technical field

The present invention relates to a control method of combined equipment, in particular to an image display device, an image data providing device, an image display system, a control method of the image display system, a control program and a recording medium for controlling an image display device displaying images. the

Background technique

In recent years, the use of digital home appliances is expanding. Furthermore, these digital home appliances having a communication function represented by digital televisions and HDD (Hard Disk Drive: Hard Disk Drive) recording devices are connected to a network, and various services can be utilized and various functions can be performed through the network. the

However, the other side requires loading multiple functions into these digital home appliances. Therefore, problems arising at the development site in response to the diversity of digital home appliances are becoming more and more serious. Specific issues include suppressing increases in development man-hours and test man-hours, reducing losses due to rework, and quickly responding to changes in equipment functions in response to rapidly changing markets. the

As can be seen from the present situation described above, there is a need for a structure capable of efficiently developing digital home appliances. In addition, it is desirable to provide a structure in which a user who has purchased the digital home appliance can easily update the program of the device once it is released to the market. the

As a method of changing the function of a digital home appliance, for example, as Java (registered trademark) in a mobile phone, etc., or downloading a program, or automatically updating a digital home appliance (such as an HDD recording device) etc. (for example, refer to the following Non-Patent Document 1 and Non-Patent Document 2). the

However, there is a problem that it is not easy to change the program of the digital home appliance to change the function of the device. the

Specifically, in the methods described in Non-Patent Document 1 and Non-Patent Document 2, the Internet browser included in the digital home appliance is software for browsing data acquired from an external device. Digital home appliances can acquire and display data distributed via the Internet using the function of an Internet browser. At this time, if the assigned data is changed, the display content of the digital home appliance can be changed. the

However, it is not easy to change the function performed by the digital home appliance for the displayed content. This is because the function of the Internet browser is determined by the program stored in the storage device by the digital home appliance. In order to change the function of the Internet browser included in the digital home appliance, the data distributor needs to update the program and distribute the updated program to the digital home appliance. the

Since the distributor must constantly update the program in order to change the function, there is a problem that the burden of development increases. Also, there is a problem for users of digital home appliances that they are forced to acquire a new program from a distributor every time a function is updated, which is inconvenient. the

In addition, the configuration for changing the functions of digital home appliances as described above is not as complete as the configuration for changing the functions of a personal computer (PC). This is because digital home appliances such as televisions and cellular phones are mostly combined equipment, and the functions performed by the combined equipment are burned in non-volatile storage devices such as ROM (read-only memory) during manufacture and cannot be stored. Implemented by rewriting the program. the

Therefore, even if the function of a digital home appliance once launched is to be changed, only the ROM itself can be replaced. However, this method cannot be said to be a simple operation that anyone can implement, and it is not realistic because it requires a huge cost. the

In addition, the above-mentioned problems are not limited to digital home appliances, as long as they are composite devices whose functions are executed by programs burned in ROM at the time of manufacture, the same problems will occur. the

Specifically, the receiving unit 63 a receives the display data request message 6 transmitted from the television 1 , and transmits the display data request message 6 accepted by the receiving unit 63 a to the request message analyzing unit 70 of the control unit 60 . The transmitting unit 63b transmits the display data 7 generated upon receiving a request from the television 1 . The transmitting unit 63 b transmits the display data 7 transmitted from the display data generating unit 62 to the requesting television 1 . the

Also, when generating the display data 7, if the display data 7 is used to display the display screen of the album photo, the communication unit 63 communicates with the album management server 3 (FIG. 2) and requests the album management server 3 to become The album 5 (or photo) of the object is displayed, and the album 5 (photo) is acquired from the album management server 3 . the

Furthermore, when the display data generating device 2 has the network album DB 8 , it is not necessary to acquire the album 5 (photo) by the communication unit 63 . In this case, the album 5 (photo) received by the receiving unit 63a from a communication terminal device such as PC4 is stored in the network album DB8. the

The request message analysis unit 70 analyzes the display data request message 6 transmitted from the television 1 . For example, when the display data request message 6 is a message requesting data for displaying a slide show display screen of a certain album, the request message analysis unit 70 extracts the album ID and the display screen ID contained in the display data request message 6 ( It can be determined that the request is information on a slide show display screen), terminal ID (information that can identify the requester's television 1 ), and other various related information. the

The pattern data selection unit 61 selects optimum pattern data for generating the requested display data according to the analysis result of the request message analysis unit 70 . The pattern data selection unit 61 selects the optimum pattern data specified by the analysis result from the pattern data storage unit 91 . The pattern data selected by the pattern data selection unit 61 is transmitted to the control script generation unit 80 which generates a control script based on the pattern data. the

The above-mentioned schema data refers to control script schema information (or a combination with format scripts) having the formats of the above-mentioned various scripts. That is, the prototype of the control script. If the information indicating the correspondence relationship between the identification information of the display object and its display position and display size information, the information specifying the operation menu screen, album title and remarks, etc. are called control scripts, then the mode data can be said to be The container before the embedded content. the

For example, when it is determined from the analysis of the request message analysis unit 70 that the data for displaying the slide show display screen is requested from the television 1, the mode data selection unit 61 selects the control unit for configuring the slide show display screen from the mode data storage unit 91. Schema information for the script. Then, the control script generating unit 80 generates a control script based on the pattern data selected above. the

The control script generation unit 80 uses the pattern data selected by the pattern data selection unit 61 to generate a control script to be included in the requested display data. the

The control script generating unit 80 extracts all information included in the display data from various information stored in the storage unit 90 according to the analysis result of the request message analyzing unit 70 (identification of the content of the control script). Then, embed the determined content (for example, album title, photo ID, screen transfer destination information, etc.) into the above pattern data to complete the control script. the

According to the above example, the completed control script becomes a control script for configuring a slide show display screen. the

The display data generating unit 62 generates the display data specified by the display data request message 6 and sends it to the television 1 . More specifically, the control script generated by the control script generation unit 80 is combined with the display object specified by the display object specification script included in the control script to generate a screen for displaying the display screen requested by the television 1. Display data. the

The display data thus generated includes a control script of optimum information obtained in accordance with the content of the display data request message 6 as a request from the television 1 . the

According to the above configuration, based on the analysis result of the request message analysis unit 70 , the optimal pattern data is selected by the pattern data selection unit 61 , and the optimal content is determined by the control script generation unit 80 . Therefore, the display data generation device 2 can create an appropriate control script based on the display data requested by the television 1 and provide it to the television 1 . The television 1 can realize the photo application function according to the appropriate control script. the

As can be seen from the above, the TV 1 can be controlled by the control script so that according to the content of the display screen (display data) requested by the TV 1 to be displayed, an operation suitable for the display data is performed. the

In this way, by generating a control script and providing it to the television 1, it is possible to easily change the function of the television 1 without performing a program update. Furthermore, since the control script is generated corresponding to the display data, it is possible to provide the television 1 with a control script personalized according to the content of the display data. the

Implementation mode 1

Background Technology and Issues

Conventionally, in devices such as televisions and mobile phones that incorporate built-in computers, when changing the appearance or specifications of installed applications, it is necessary to change the combined applications. the

For example, when realizing a GUI screen or the like with a web browser, changing the display position and the like can be realized by rewriting the content (display data) that is original data. the

Patent Document 1 (Japanese Laid-Open Patent Publication: Japanese Unexamined Patent Publication No. 2005-51563 (published on February 24, 2005)) discloses that while the layout of the image displayed on the screen on the receiving side is grasped by the transmitting side, it can be changed by simple operations. The content delivery method of its layout and the content delivery system. the

However, changing the functions that the browser itself has still requires changing the programs that are incorporated into the device. Furthermore, it is not possible to flexibly change the function of the content receiving side (combined device (television 1)) according to the content of the transmitted content (display data). the

In the above-mentioned method of Patent Document 1, if the distributor prepares the program in advance so that the setting file and the plug-in can be distributed and changed later, it is not necessary to rewrite the entire software in order to change the function of the distribution target device. However, even in this case, in order to flexibly change the function of the device according to the content to be delivered, it is necessary to deliver the above-mentioned setting file of the operation menu corresponding to the content with the content. Therefore, there is a problem that it is difficult to manage content and set files regardless of the distribution side or the device of the distribution destination. the

Therefore, in this embodiment, the TV 1 and the display data generating device 2 (network album system 100) that can use control scripts that are included in the display data and are easy to manage will be described. According to the content of the display data (display screen/content) displayed by the television 1, the operation options of the operation menu to be displayed are selected, so that the executable functions of the television 1 are personalized. the

In the example shown in FIG. 7, the display data request message 6 is formed by integrating five records into one structure. In the display data request message 6 shown in FIG. 7, the first column C101 indicates the data name, and the second column C102 indicates the data content with the data name. In addition, the data type of each data can be appropriately selected according to the content, capacity, and use indicated by each data. the

The record R1 indicates the album ID (identification information) of the album to which the photograph (request image) to be displayed on the display screen when the display data request message 6 requests the slide show display screen belongs. The record R2 indicates the photo ID (identification information) of the photo to be displayed on the display screen. In this embodiment, the so-called photo ID refers to the uniquely determined display order in the album, and "NO.1" in FIG. 7 indicates the photo whose display order is 1 in the album identified by record R1. the

The record R3 indicates a display screen ID for identifying the type of display screen requested by the display data request message 6 . In the example shown in FIG. 7, the display screen ID "cr_C" means a slide show display screen. "Therefore, this display data request message 6 is a message requesting a slideshow display screen for slideshow display of the photos whose display sequence is 1 in the album indicated by the record R1.

The record R4 indicates a terminal ID for identifying the television 1 as the requester for generating the display data request message 6 . In the example shown in FIG. 7, the IP address of the television 1 is stored. Thereby, the display data generating device 2 can specify from where the display data request message 6 was sent, and thus can specify a return destination of the generated display data 7 . In addition, the terminal ID may be any information as long as the display data generating device 2 can uniquely identify each terminal (television 1) receiving the display data 7 in the network album system 100. The display data generating device 2 may use a terminal ID provided every time the TV 1 registers, or may use a MAC address, a product serial number, or the like as the terminal ID. the

Furthermore, the display data request message 6 may include specification information of the television 1 as shown in records R5 to R7.

This signal is notified by the event processing unit 11 to the display target ID specifying unit 31 , and the display target ID specifying unit 31 specifies the album ID selected by the user from the album ID storage unit 53 . Alternatively, the user may manually input the album ID while the album ID input screen is displayed on the display unit 15, and at the same time transmit a signal of the pressed button to the display target ID determination unit 31, and determine it as the album ID. the

As a method of specifying photo IDs, for example, it is considered that slide shows must be displayed in the display order in advance. When the event processing unit 11 detects that an instruction input for instructing the start of the slide show is made, the display object ID specifying unit 31 specifies NO. 1 indicating that the display order is the first as the photo ID. Or, in the state where the slide show display screen whose display order is No. ID is enough. the

The request display screen specifying unit 32 specifies the type of display screen to be requested by the display data request message 6 among the various display screens described above. The requested display screen determining unit 32 determines which display screen is requested according to the event detected by the event processing unit 11 and the operating state of the television 1 at the time. the

In the request rule storage unit 54, for (1) the combination of the event detected by the event processing unit 11 and (2) the operating state of the TV set 1, it is stored in correspondence with the display screen ID of the display screen of (3) the request, The request display screen determination unit 32 can determine which display screen is to be requested based on the notification from the event processing unit 11 and the request rule storage unit 54 . For example, when the event processing unit 11 detects that the photo application function has been activated by the display data execution processing unit 40 of the television 1, the request display screen determination unit 32 determines the initial screen of the application as the requested display screen. the

The display screen ID of the display screen specified by the requested display screen specifying unit 32 is, for example, included in the record R3 of the display data request message 6 shown in FIG. 7 . the

The related information extracting unit 33 acquires necessary related information included in the display data request message 6 from the related information storage unit 52 among various related information related to the television 1 registered in advance. the

The photo rotation control unit 143 controls the basic function execution unit 42 to execute rotation and display processing of a photo according to the operation function definition script 132 . For example, when the user selects an operation option of “rotate right 90 degrees”, the photo is displayed on the display unit 15 in a state of turning the photo 90 degrees to the right. the

The display control unit 24 draws a display area based on the display screen data notified from the control script execution unit 41 , and displays the display screen specified by the display data on the display unit 15 on the television 1 . the

Data Execution Processing Flow for TV Display

FIG. 10 is a flowchart showing the flow of display data execution processing in the television 1 . In FIG. 10 , as an example, the processing flow of the television 1 that displays the slide show display screen and executes the slide show by receiving the requested data for displaying the slide show display screen will be described. the

When receiving a notification from the event processing unit 11 to start display data execution processing, the control script analysis unit 140 acquires the received data for displaying the slide show display screen from the display data storage unit 51 according to the notification, and includes The control script is analyzed (S101). the

The slide show execution control unit 141 executes a script (such as a layout definition script) for displaying the slide show display screen on the display unit 15 ( S102 ). The display control unit 24 draws the slide show display screen according to the control of the slide show execution control unit 141 and displays it on the display unit 15 ( S103 ). Accordingly, the first drawing is completed, and a photograph as the display object 111 included in the data for displaying the slide show display screen can be displayed, for example, as shown in FIG. 11( a ). Here, it becomes an event standby state (for example, the user performs a button input through the operation unit 13, etc.) (S104). Also, when the slide show is automatically reproduced, as shown in FIG. 11( a ), the slide show execution control unit 141 displays an automatic film advance icon 1101 indicating this, according to the control script. Alternatively, the slideshow execution control unit 141 may display the photo title 1102, the operation method screen 1103, and the like in accordance with the control script. the

For example, when drawing for the first time ( FIG. 11( a )), when the user operates and presses the yellow button (not shown) or the OK button (not shown) provided on the operation unit 13, the signal is transmitted through the operation accepting unit 21. Going to the event processing section 11, the event processing section 11 detects the event (YES in S104). the

When it is known from the judgment of the event processing unit 11 that the yellow button has been pressed (y in S105 ), the control script execution unit 41 executes the corresponding processing. the

Here, the yellow button of the operation unit 13 is a button for operating the TV 1 to display the operation menu 1104 ( FIG. 11( b )), and when pressed while the operation menu 1104 is displayed, it is a closing operation. The menu 1104 is a button for operating the television 1 to return to the state shown in FIG. 11( a ). In this way, the correspondence between each button provided on the operation unit 13 and the function to be executed by the television 1 when the button is pressed is described in the operation content definition script included in the control script. the

When the control script execution unit 41 receives the notification from the event processing unit 11, it is determined whether or not the operation menu 1104 is opened when the yellow button is pressed (S106). the

Then, when it is determined that the menu 1104 has not been opened ("No" in S106), the operation menu control unit 142 displays the corresponding menu 1104 according to the operation menu determination script 122 of the control script 110 included in the data for displaying the slide show display screen. The operation menu 1104 of the content corresponding to the data is displayed (S107). Specifically, the basic function execution unit 42 is controlled to transfer data to be displayed to the display control unit 24 . Accordingly, the display screen of the display unit 15 shifts from FIG. 11( a ) to FIG. 11( b ). the

On the other hand, when it is determined that the operation menu 1104 is being displayed (YES in S106 ), the operation menu control unit 142 closes the displayed operation menu 1104 in accordance with the control script 110 . Accordingly, the display screen of the display unit 15 shifts from FIG. 11( b ) to FIG. 11( a ). the

In S105, when it is known from the judgment of the event processing unit 11 that the OK button has been pressed (k in S105), the control script execution unit 41 executes the corresponding processing. the

Here, when the OK button of the operation unit 13 is pressed in the state where one of the operation options in the above-mentioned operation menu 1104 is selected, if the operation option has a sub-operation menu, the TV 1 is operated to open the sub-operation menu. Buttons for menus. For example, as shown in Fig. 11(b) and Fig. 11(c), if the OK button is pressed in the state where the operation option 1105 representing "photo rotation" is selected, the operation menu control section 142 will display the sub-operation menu 1106 . Or, if the selected operation option has no sub-operation menu (if not defined in the operation menu determination script), then when the operation option is selected, the control script execution unit 41 executes the sub-operation menu corresponding to the operation option according to the control script 110 . processing. In addition, when the OK button is pressed while none of the menus are open, the slideshow execution control unit 141 performs slideshow execution processing. the

More details are described below. the

Similar to S106, when the control script execution unit 41 receives the notification from the event processing unit 11, it is determined whether or not the operation menu 1104 is opened when the OK button is pressed (S109). the

Then, when it is determined that the operation menu 1104 has not been opened ("No" in S109), the slide show execution control unit 141 performs a slide show execution process (S110). Specifically, when the OK button is pressed while the display screen of FIG. 11( a ) is being displayed, the slide show execution control unit 141 displays a slide show of photos in the display order next to the photo being displayed on the display screen. the

On the other hand, when it is determined that the operation menu 1104 is open (YES in S109), when the OK button is pressed, the control script execution unit 41 determines which of the operation options of the open operation menu 1104 is focused on (S111 ). The so-called focus state means the state of using the cursor to select an operation option. In this embodiment, in order to distinguish it from other operation options, only the display area of the selected operation option is displayed in another color (for example, the display area representing "photo rotation" Action option 1105). the

As shown in FIG. 11( b ), when it is determined that the OK button is pressed in the state of focusing on the operation option 1105 representing "photo rotation" ("Yes" in S112), the control script execution unit 41 then proceeds to determine the Opening and closing of the operation menu and the focus position in sub-operation options (S113). the

Here, when it is determined that the sub-operation menu 1106 is closed (A in S113), the operation menu control unit 142 displays the sub-operation menu corresponding to the operation option indicating "photo rotation" according to the operation menu determination script 122 (S114). FIG. 11(c) shows an example of a sub-operation menu 1106 in which operation options 1105 are displayed. the

On the other hand, when it is determined that the focus is on a certain operation option in the sub-operation menu 1106 of the operation option 1105 (for example, "turn left 90 degrees" or "turn right 90 degrees" shown in FIG. 11(C) (S113 In B), the photo rotation control part 143 controls the basic function execution part 42 according to the operation function definition script 132, and executes photo rotation processing (S115). For example, in the state of focusing on the sub-operation option of "turn left 90 degrees" ( Fig. 11 (c)) when the confirm button is pressed, the photo rotation control part 143 carries out the processing of turning left 90 degrees to the horizontal photo 1107 shown in Fig. 11 (c). Thus, as shown in Fig. 11 (d), the photo It is displayed on the display unit 15 as a vertical photo 1108 turned 90 degrees to the left.

On the other hand, when it is determined that the focus is on an operation option other than the operation option 1105, when the operation option has a sub-operation menu and the sub-operation menu is closed ("No" in S112 and A in S116), The operation menu control unit 142 displays a sub-operation menu of the above-mentioned other operation options (S117). On the other hand, when the sub-operation menu of the above-mentioned other operation options is opened and focused on a certain sub-operation option ("Yes" in S112 and B in S116), the control script execution unit 41 defines the script 132 according to the operation function, Execute the function corresponding to the sub-operation option (S118). the

In S116 , when the operation option is an option without a sub-operation menu, the control script execution unit 41 executes the function corresponding to the operation option according to the operation function definition script 132 . the

In addition, when displaying the rotated photo after the photo rotation processing in S115, if the script "close the operation menu after photo rotation processing" is included in the control script, then as shown in FIG. 11(d), the photo rotation control unit 143 When the operation menu is closed, the rotated photo is displayed. When the above-mentioned "close operation menu" script is not included, as shown in FIG. 11( e ), the photo rotation control unit 143 displays the rotated photo while keeping the operation menu open. the

FIGS. 12 to 15 are diagrams showing specific examples of control scripts that each part of the control script execution unit 41 refers to when executing the above-mentioned display data execution processing. the

The script 132a shown in FIG. 12 is included in the operation function definition script 132 shown in FIG. 3 . In the script 132a, it is described which function is to be executed according to the display state when the yellow button is pressed. The control script execution unit 41 (operation menu control unit 142 ) can execute the above-mentioned processes of S106 to S108 according to the script 132 a. the

The script 132b shown in FIG. 12 is included in the operation function definition script 132 shown in FIG. 3 . In the script 132b, it is described which function is to be executed according to the display state of the main operation menu and the sub-operation menu (sub-operation menu 1106 of FIG. 11(c) ) when the yellow button is pressed. More specifically, the description is: when the OK button is pressed, if the sub-operation menu is not opened, then open the sub-operation menu, if the sub-operation menu is opened, then switch the sub-operation menu to non-display, and execute the sub-operation option function. the

For example, the script 132d defines the photo rotation function to be executed by the photo rotation control unit 143 when one of the photo rotation sub-operation options (in the sub-operation menu 1106) is selected by pressing the OK button. the

The control script execution unit 41 (the operation menu control unit 142 and the photo rotation control unit 143 ) can execute the above-mentioned processing of S113 to S118 according to the script 132b. the

The script 122a shown in FIG. 13 is included in the operation menu determination script 122 shown in FIG. 3 . According to the description of the script 122a, the main operation menu 1104 to be displayed (for example, FIG. 11(b)) is determined according to the content of the currently displayed display screen. The following function is defined in the above-mentioned script 132a (Fig. 12): that is, when the yellow button is pressed, the operation menu (g id="menu") determined by the script 122a is displayed. the

The script 122b shown in FIG. 13 is included in the operation menu determination script 122 shown in FIG. 3 . The script 122b determines the sub-operation menu 1106 of the operation option 1105 indicating "photo rotation". The following function is defined in the operation function definition script 132: that is, when the OK button is pressed in the state where the operation option 1105 is displayed, the sub-operation menu (g id="submenu2") determined by the script 122b is displayed. the

Here, when the landscape photo 1107 shown in FIG. As the case where rotation is not required, it is assumed that the album author (the photo holder) is for reasons such as that it is inappropriate to display the photo vertically because the television 1 itself does not have the function of rotating the photo, or that the state of the horizontal photo 1107 is already suitable for the orientation of the photo. Own) U don't want to rotate it. the

In this case, it is only necessary to provide the optimal operation menu determination script 122 to the television 1 based on the photograph (content of the display data) as the object to be displayed. the

In such a case, it is desirable that the television 1 not execute the function of "photo rotation" with respect to the display data including the above-mentioned photo. In this case, the display data generation device 2 may provide a control script including the script 122a' shown in FIG. 14 instead of the script 122a shown in FIG. 13 . In this case, the operation function definition script 132 of the control script does not need to include a script related to the photo rotation function. Script 122a' shown in FIG. 14 determines that operation menu 1104 (FIG. 16) does not include operation option 1105 indicating "photo rotation" compared to script 122a. According to such a script, as shown in FIG. 16 , the operation menu control unit 142 can display the operation menu 1104 on the display unit 15 . the

As can be seen from the above, the optimal control script is provided to the television 1 according to the content of the display data, whereby the television 1 can always display an optimal operation menu according to the display data. the

Furthermore, by appropriately changing the control script, it is also possible to control the television 1 so that only the operation options specified in the operation menu 1104 are displayed in two levels, similarly to the sub-operation menu. For example, although photo rotation can be performed, it is not desirable to actively use the photo rotation function on the side that provides the photo. In this case, as long as the operation menu determination script 122 (Fig. 17(a)) and the operation function definition script 132 are provided to the TV set 1, the operation option of "other" is set in the operation menu 1104, only in this option When selected, it is only necessary to display the operation option 1105 in the second level, similar to the sub-operation menu. the

By providing the above-mentioned operation menu specifying script 122 and operation function defining script 132 to the television 1, as shown in FIG. Also, when the above-mentioned operation option 1105 is selected, the photo rotation control unit 143 can execute photo rotation processing. the

Alternatively, the following configuration may be adopted: that is, when the same control script for displaying the operation menu 1104 is provided to the television 1 regardless of whether the picture can be rotated, the control script execution unit 41 judges whether the picture can be rotated according to the control script. , to determine whether to display the sub-operation menu 1106 of "photo rotation". the

For example, the display data generating device 2 provides the television 1 with a script 132b' shown in FIG. 15 instead of the script 132b of FIG. 12 . Accordingly, the television 1 operates according to the script 1230 described in the script 1230 to execute subsequent processing only when photo rotation is possible. That is, the operation menu control unit 142 executes the process of displaying the sub-operation menu 1106 of “photo rotation” specified by the script 122b of FIG. the

As can be seen from the above, by providing the script 132b' shown in FIG. 15 to the TV 1, the TV 1 can display the sub-operation menu 1106 only when the photo is rotatable. the

In addition, in S110 shown in FIG. 10 , the slide show execution process executed by the slide show execution control unit 141 can be controlled by the script 132 c shown in FIG. 12 . the

When the user presses the OK button of the operation unit 13 while the operation menu 1104 shown in FIG. the

When the slide show execution control unit 141 presses the OK button while the slide show itself is being played back automatically, instead of displaying the icon 1101 showing that the film is progressing automatically, it displays the icon 1109 that is stopping the film progressing, and stops the slide show. Automatic playback of movie shows. On the other hand, when the OK button is pressed while playback of the slide show is stopped, instead of the icon 1109 showing that the film is being advanced, the icon 1101 being automatically advanced is displayed, and the automatic playback of the slide show is restarted. As described above, by providing the script 132c to the television 1 and pressing the OK button while the operation menu is not open, the television 1 that controls the automatic reproduction of the slide show can be realized. the

Next, a detailed description will be given of the display data generation device 2 that generates display data including the above-mentioned control script in response to a request from the television 1 and supplies it to the television 1 . the

The display data generating device 2 can acquire information stored in the web album DB 8 through the communication unit 63 as needed. the

When each part of the request message analysis unit 70 receives the display data request message 6 ( FIG. 7 ) received from the television 1 , it executes the request message analysis process shown in FIG. 5 ( S4 ). Moreover, each part of the control script generation part 80 executes the control script generation process for generating a control script using the pattern data selected by the pattern data selection part 61 in S5 (S6). the

In the following description, an example of the case where the television 1 receives a display data request message 6 requesting a slide show display screen (display data) as shown in FIG. structure. the

The display data generation means 2 generates display data 7 ( FIG. 3 ) as a response to the display data request message 6 ( FIG. 7 ). Specifically, based on the content of the slideshow display screen requested by the display data request message 6, an operation menu screen (operation menu determination script 122 (FIG. 3)) is generated, and the TV screen when each operation option is selected is specified. 1 (generate operation function definition script 132). the

The display object ID acquiring section 71 of the request message analyzing section 70 acquires a display object ID for identifying a display object to be displayed included in the display data request message. In this embodiment, for example, the album ID and photo ID included in the display data request message 6 shown in FIG. 7 are acquired. Accordingly, the display data generation device 2 can determine which photo in which album is requested to display the display screen for slideshow. the

The display screen ID acquiring unit 72 acquires the display screen ID indicating the type of the display screen included in the display data request message. As described above, in this embodiment, there are various types of display screens provided by the display data generation device 2 to the television 1. Therefore, the display data request message includes a display screen ID indicating which type of display screen the television 1 requests. The display screen ID acquisition unit 72 acquires the display screen ID included in the display data request message, so that the display data generation device 2 can determine which display screen data is requested. the

In addition, when there is only one type of display screen generated in the display data generating device 2, the display screen ID acquisition unit 72 may not be provided. the

The related information acquisition unit 73 acquires the related information of the television 1 that is the requester of the message included in the display data request message. Using the example in FIG. 7 , the related information acquisition unit 73 acquires the terminal ID and specification information (the number of pixels of the screen) of the television 1 from the display data request message 6 . the

However, related information is not limited to the example shown in FIG. 7 . For example, as shown in the related information table of FIG. 8, the display data request message 6 includes user information related to the user of the TV set 1, other specification information (screen size, model name, software version) of the TV set 1. information, etc.), or the setting information set in the television 1, adopts a structure to acquire these information. Specifically, the model name of the TV set 1 stored in the related information table (FIG. 8) and the version information of the software installed on the TV set 1 in order to realize the photo application function are included in the display data request shown in FIG. In the message 6 , the relevant information acquiring unit 73 can acquire the model name and software version information of the requesting television 1 from the display data request message 6 . the

The display data generating device 2 uses various related information acquired by the related information acquiring unit 73 as a judgment material for generating optimal display data (control script) according to the request of the television 1 . the

In the present embodiment, the related information acquiring unit 73 acquires the screen pixel count of the television 1 as related information. Therefore, the display data generation device 2 can generate optimal display data (control script) based on the number of pixels or the size of the photograph specified as the display object and the number of screen pixels of the television 1 . the

Or, when the user information includes the age information of the user and the available display data varies with age, the display data generating device 2 can select the control data contained in the display data according to the age information acquired by the related information acquisition part 73. Script and display objects. Alternatively, when requesting display data with a limit on the available age, the display data generating device 2 can generate an error message including an error message instead of generating the requested display data if the age of the user does not satisfy the condition. processing of display data, etc. the

In addition, in the display data generating device 2 , when the above-mentioned related information is not used when generating the display data, the related information acquisition unit 73 may not be provided. the

As described above, the pattern data selection unit 61 selects the optimum pattern data for generating the requested display data from the pattern data storage unit 91 . In the present embodiment, pattern data as a prototype of the display screen is selected based on the display screen ID acquired by the display screen ID acquisition unit 72 . the

FIG. 19 is a diagram showing an example of a pattern data table stored in the pattern data storage unit 91 . In the example shown in FIG. 19 , various display screen prototypes of the above-mentioned various display screens (single-image display screen, slide show display screen, thumbnail display screen, etc.) are stored in association with display screen IDs. the

In the example shown in FIG. 7 , the display screen ID acquiring unit 72 acquires the display screen ID “cr_C” from the display data request message 6 . Therefore, the pattern data selection unit 61 refers to the pattern data storage unit 91 shown in FIG. The content of the pattern data selected by the data selection unit 61 is synthesized and completed as a control script.

The control script generation unit 80 uses the pattern data selected by the pattern data selection unit 61 to generate a control script to be included in the requested display data. the

The display object attribute determination unit 81 of the control script generation unit 80 determines the attribute of the display object specified by the display object ID acquisition unit 71 . Display object attribute judging section 81 acquires attribute information (album information/photo information) of an album (photo) from the network album DB 8 (FIG. Attributes. the

For example, the display object attribute determination unit 81 can determine whether the photo specified as the display object needs a rotation function, whether the number of pixels of the photo is smaller than the number of pixels of the TV set 1 of the requesting party, whether to add a note to the photo, whether to update the photo Plus copyright protection lock, etc. However, it is not limited to the above-mentioned example, and the display object attribute determination unit 81 can identify the display object according to the relevant information included in the display data request message received from the television 1, the album information of the specified album, and the photo information of the photo. Various attributes are judged. the

The image analysis unit 82 analyzes the image data when the display object is image data (photographs in an album, etc.). the

More specifically, the color information of each pixel of the photo is analyzed to determine the color tone of the photo. As shown in FIG. 11( b ) and FIG. 11( c ), the operation menu 1104 is displayed superimposed on the photo. In this case, it is preferable that the color of the operation menu 1104 is more conspicuous than the tone of the photograph so that the user can easily see it. Therefore, the image analysis unit 82 can specify a color that stands out from the color tone of the photo as the color of the operation menu, thereby specifying the color tone of the photo, and outputting it to the operation menu generation unit 85 . the

In addition, the image analysis unit 82 may perform image recognition processing to recognize the shooting position of the subject in the photo. Then, the processing result is output to the operation menu generation unit 85 . Accordingly, the operation menu generation unit 85 can determine the display position of the operation menu without covering the subject of the photo. the

FIG. 20 is a diagram showing an example of an album information table stored in the network album DB8. In the example shown in FIG. 20 , album information is stored as a record associated with an album ID for each album, forming a table structure. the

The column of "Album ID" indicates an album ID for identifying an album. The display object attribute determination unit 81 acquires the album information of the album specified by the display object ID acquisition unit 71 based on the album ID. the

The column of "album author" indicates the album author who made the album. The "album title" column indicates the title of the album. The column of "Album Remarks" indicates the remarks on the album given by the author of the album. The column of "album creation date" indicates the album creation date when the album was created (registered in the album management server 3). The album basic information is the information set and registered by the album author U in the album management server 3 through the PC 4 . the

The "Number of Photos" column indicates the number of photos contained in the album. The column of "photo ID" indicates a photo ID for identifying a photo included in the album. In the present embodiment, photo IDs represent display order. When displaying a plurality of photos in a slide show or as thumbnails, the control script generator 80 generates a layout definition script so that the photos are displayed in the display order described above. The "photo file name" column indicates the file name of the photo. the

In addition, the columns of "sound file name" and "effect ID" will be described later. the

FIG. 21 is a diagram showing an example of a photo information table stored in the network album DB8. In FIG. 21, as an example of the photo information table, the photo information table shows a list of photos included in the album (FIG. _20) whose album ID is _0125478225142584. However, the photo information table stored in the web album DB 8 is not limited to this table. That is, in the network album DB 8, the above-mentioned photo information table is prepared for each album managed by the album information table of FIG. 20 . the

The display object attribute determination unit 81 and the image analysis unit 82 are configured by referring to the photo information table associated with the album based on the album ID acquired by the display object ID acquisition unit 71 . the

As shown in Figure 21, the photo information table for managing album photos all stores a record for each photo, storing: the photo ID (display order) that uniquely identifies the photos in the album; and the " Photo file name", "horizontal pixel number", "vertical pixel number", "data size", "photo title", "photo note", "rotation function", "copyright protection information", and photo data body. the

The "horizontal pixels" column indicates the horizontal pixels of the photo. The column of "Vertical Pixels" indicates the vertical pixels of the photo. The "Data Size" column indicates the data size of the photo. The "photo title" column indicates the photo title set by the album author for each photo. The column of "Photo Remarks" indicates the remark on the photo registered by the album author for each photo. the

The column of "rotation function" indicates whether or not the rotation function is necessary. A photo whose "rotation function" is "yes" means that the photo needs to be rotated, and a photo whose "rotation function" is "does not" means that the photo does not need to be rotated. The necessary/non-necessary setting of the rotation function may be performed when the album author U uploads the photo to the album management server 3 . Album creator U can set the rotation function to "do not" and upload photos that do not want to be rotated. the

In addition, instead of the column of "rotation function", a column of "vertical direction" indicating the vertical direction of the photo may be provided. Therefore, if the actual up-and-down direction of the photo coincides with the up-and-down direction of the photo, the display object attribute determination unit 81 can determine that the rotation function is unnecessary. the

The column of "copyright protection information" indicates whether there is copyright protection information assigned to the photograph. A photo with "Copyright protection information" as "Yes" means that a copyright protection lock is attached, and printing and copying are prohibited, and a photo with "No" means that printing and copying are free. the

The above album information ( FIG. 20 ) and photo information ( FIG. 21 ) are read as necessary when the image analysis unit 82 analyzes the photo when the display object attribute judging unit 81 judges the attribute of the album (photo). the

As described above, the display target attribute judging unit 81 and the image analyzing unit 82 refer to the network album DB 8, judge the properties of the album and the photo that are the data to be displayed, perform image analysis of the photo, and output the result to the operation option selection part 83 and an operation menu generating part 85. the

In addition, in the above description, it has been explained that the album information and the photo information are formed by a table structure, and the table structure has records composed of multiple columns, but the present invention is not limited thereto. The album (photograph) information may be appropriately structured so as to include information necessary for the display data generating device 2 to determine the attribute of the display object. the

In addition, in the above description, the structure in which the display object attribute determination unit 81 determines the necessity of the rotation function of the photo based on the "rotation function" of the photo information is adopted, but the present invention is not limited thereto. For example, the image analysis unit 82 may specify the top and bottom of the photo using an image analysis algorithm, and determine whether or not it matches the top and bottom of the actual photo data. If the specified top and bottom of the photo match the top and bottom of the actual photo, the display object attribute determination unit 81 determines that the rotation function is not required for the photo. the

The operation option selection unit 83 selects an operation option included in the operation menu displayed on the display screen. The operation option selection unit 83 selects operation options (functions of the television 1 ) to be included in the operation menu based on the determination and analysis results output by the display object attribute determination unit 81 and the image analysis unit 82 . Accordingly, a control script for displaying an optimal operation menu corresponding to the contents of the display data (display screen) can be completed. In addition, the above-mentioned control script can provide various functions of the operation options listed in the operation menu to the television 1 . the

The operation option selection unit 83 refers to the selection rule stored in the option selection rule storage unit 93 , and selects an operation option to be added to the operation menu on the display screen based on the determination result and the analysis result. the

FIG. 22 is a diagram showing an example of a rule table for selecting an operation option by the operation option selection unit 83 stored in the option selection rule storage unit 93 . the

As shown in Fig. 22, in the rule table, each function that can be provided to the television 1 according to the description of the control script is listed in advance, and each function and various information related to each function and the function ID (column C1) stored in association. the

"Function" in the column C2 indicates the content of the functions provided to the above-mentioned television 1 . the

The "judgment method" in the column C3 indicates the procedure of judging the requested photograph or display data request message. These respective determination processes are executed by the display object attribute determination section 81 (also the image analysis section 82, the operation option selection section 83, and the like). Based on the determination result, the operation option selection unit 83 can determine whether to add a function operation option to the operation menu. the

"Selection rule" in column C4 indicates a rule for the operation option selection unit 83 to determine whether to add the operation option of the function to the operation menu (or sub-operation menu) based on the judgment result generated by the judgment method shown in column C3. In the column C4, for each determination result (搃f) in the column C41, a selection action (搕hen) for specifying an action to be taken by the operation option selection unit 83 is specified (column 42). the

As described above, the operation option selection unit 83 selects the operation option to be added based on the determination result of the display object attribute determination unit 81 according to the “selection rule” in the column C4. the

In addition, even if neither judgment is performed, the information in the column C3 and the column C41 is unnecessary for the functions (for example, functions 5 to 7) that are common to all display data and should always be provided. In this embodiment, for functions 5 to 7, it is specified as the selection rule of "always add in the operation menu"

The selection result by the operation option selection section 83 (for example, the function ID of the function selected by the operation option selection section 83 ) is transmitted to the operation function definition generation section 84 and the operation menu generation section 85 . the

Based on the function ID selected by the operation option selection unit 83, the operation function definition generating unit 84 extracts from the operation function storage unit 94 the content of the operation function definition script 132 (FIG. 3 ) for the television 1 to execute the function, and embeds it in the pattern data. middle. the

Based on the function ID selected by the operation option selection unit 83 , the operation menu generating unit 85 generates an operation menu (operation menu specifying script 122 ( FIG. 3 )) including the operation options of the function. Specifically, the operation option name (text data (contents) indicating each operation option in the operation menu 1104 of FIG. 11( b )) is extracted from the operation function storage unit 94 based on the function ID, and embedded in the pattern data. the

In addition to embedding the above-mentioned operation option names (contents), the operation menu generator 85 calculates the display position and display size (start point X and Y coordinates, width, height(content)), and embedded in the schema data. the

In addition, as described above, the operation menu generation unit 85 may determine the display color of the operation menu or the display position of the operation menu based on the analysis result of the image analysis unit 82 . the

As a method of determining the display color, it is conceivable, for example, to select a blue color when the overall tone of the photo is relatively red, or to select a black color when the color tone of the superimposed position of the operation menu is relatively white. the

FIG. 23 is a diagram showing an example of a function table stored in the operation function storage unit 94 . The feature table stores information about what should be embedded in the schema data. the

As shown in FIG. 23 , in the function table, the functions that can be provided to the television 1 according to the description of the control script are listed in advance, and each function and various information related to each function are stored in association with the function ID. . Different from the rule table (FIG. 22), various information is stored in association with each sub-operation option (function 1-1, 1-2, etc.) in the sub-operation menu. the

"Operation option name" in the column C5 indicates text data representing each operation option in the operation menu 1104 of FIG. 11( b ). The operation menu generation unit 85 embeds the text data (operation option name) of the column C5 and the display position and display size information of each operation option into the pattern data to complete the operation menu specifying script. the

"Script" in the column C6 indicates an operation function definition script that defines predetermined processing to be executed by the television 1 as a photo application function. As shown in Fig. 23, scripts are prepared for each function. The operation function definition generation part 84 embeds the script of the column C6 into pattern data, and completes each script prepared for each function into one operation function definition script. the

In addition, in FIG. 23, the script of the column C6 is shown in sentences for easy understanding, but the operation menu generator 85 actually extracts from the column C6 and embeds the information in the pattern data, as shown in the script 132b of FIG. It is constituted as text data described by XML. the

In addition, the function table shown in FIG. 23 is an example for explanation, and does not limit this invention. In addition to the functions shown in FIG. 23 , the display data generating device 2 can provide the TV 1 with all other functions (second functions) executed when the TV 1 displays a picture (the first function). the

Fig. 24 is a diagram showing a specific example of pattern data. In FIG. 24 , only a portion of the operation menu specifying script 122 generated by the operation menu generating unit 85 in the pattern data of the display screen ID “Scr_C” shown in FIG. 19 is shown. Script 240 is a prototype of a script for specifying an operation menu, and script 250 is a prototype of a script for specifying a sub-operation menu. the

In FIG. 24, "_***_" indicates the part where the operation menu generation part_85 embeds the content. Specifically, the replacement position 241 is replaced with the operation option name, the replacement position 242 is replaced with the display position of the operation option (X and Y coordinates of the starting point), and the replacement positions 243 and 244 are replaced with the display size (width) of the operation menu. and height). the

In this way, when the actual values determined by the operation function definition generation unit 84 are embedded in all the replacement positions, the operation menu determination script 122 ( FIG. 13 ) in the control script is completed. the

25 and 26 are diagrams showing specific examples of the operation function definition script generated by the operation function definition generation unit 84 . The operation function definition generation part 84 determines the script from the function table (column C6) of the operation function storage part 94 according to the selection result of the operation option selection part 83, thereby completing the operation function definition script of each function. Fig. 25 shows a specific example of an operation function definition script defining a "rotation function". According to the operation function definition script of FIG. 25, when the photo rotation process is executed according to the script 132d of FIG. 12, the photo currently being displayed at that time is not displayed, and the rotation position is calculated (the variable rotateno is calculated). Then, based on the calculated rotation position, the rotated photo is displayed (script 132d in FIG. 12 ), and the photo rotation function is realized. FIG. 26 shows a specific example of an operation function definition script defining a "remark display function". The operation function definition generating unit 84 embeds the scripts of these functions into the pattern data, thereby completing one operation function definition script. the

The script synthesis unit 86 synthesizes various scripts (for example, the operation menu determination script 122 ( FIG. 13 ) or the operation function definition script 132 ( FIG. 12 ), etc.) generated by the above-mentioned control script generation unit 80 to generate a control script. . The control script generated by the control script synthesizing unit 86 includes a script for providing appropriate functions to the television 1 in accordance with the content of the display data requested by the display data request message. the

In addition, in the above-mentioned example, each part of the control script generation part 80 was only described as generating the operation menu determination script 122 and the operation function definition script 132 according to the pattern data, but the present invention is not limited thereto. Each part of the control script generation part 80 (not shown) embeds appropriate content in the pattern data selected by the pattern data selection part 61, and completes the display object specification script 121, the attribute information specification script 123, and the state transition shown in FIG. The script 131 is defined and provided to the script synthesis unit 86 . the

The control script generated by the script synthesis unit 86 is supplied to the display data generation unit 62 . The display data generation unit 62 synthesizes the control script acquired from the script synthesis unit 86 and the display object to generate display data, and supplies the data to the requesting television 1 through the transmission unit 63b. the

Examples of the display objects specified by the display data generation unit 62 include album information, photo information, photographs stored in the network album DB 8, and other images (images of operation buttons, etc.) stored in the display object storage unit 92. common image on each display screen), etc. the

In this way, the television set 1 receiving the above-mentioned display data can display the requested display screen (such as a slide show display screen), and during the display process of the display screen, it can execute according to the control script of the display data. Scheduled photo app functionality. The display data generating device 2 can appropriately change the control script according to the content of the requested display data, and provide it to the television 1 . As can be seen from the above, the functions of the television 1 can be easily changed according to the contents of the displayed display data. the

Furthermore, when a new photo application function is added to the service of the network album system 100, it is expected that the function can also be added to the TV 1 that has been distributed in the market. According to the display data generation device 2 of the present invention, a new function can be easily added to the television 1 simply by newly generating the control script and providing it to the television 1 . For example, when adding a photo fade-in function to a slide show, you only need to describe the function of the above effect in the control script, and add the corresponding operation option in the operation menu confirmation script. the

FIG. 27 is a flowchart showing in detail the flow of processing (S3 to S8 in FIG. 5 ) for generating display data in the display data generating device 2 . the

When the receiving unit 63a receives the display data request message ( FIG. 7 ) from the television set 1 ("Yes" in S201), the request message analysis unit 70 analyzes the received display data request message (S202). In other words, the display object ID acquiring unit 71 acquires an album ID and a photo ID, the display screen ID acquiring unit 72 acquires a display screen ID, and the related information acquiring unit 73 acquires specification information (number of pixels of a screen). the

Then, the pattern data selection unit 61 selects optimum pattern data for generating the requested display data from the pattern data table in the pattern data storage unit 91 based on the display screen ID (S203). Here, as an example, pattern data for generating data for displaying a slide show display screen is selected. the

The control script generating unit 80 generates a control script included in the display data based on the selected pattern data. First, the control script generator 80 specifies a photo to be displayed stored in the network album DB 8 based on the album ID and the photo ID. the

The display object attribute determination unit 81 acquires photo information ( FIG. 21 ) of the identified photo from the Internet album DB 8 ( S204 ). the

Then, the display object attribute determination unit 81 determines the attribute of the photograph based on the acquired photograph information and the specification information included in the display data request message (S205). The details are as follows. the

(1) Determine whether the top and bottom of the photo are correct. the

The display object attribute judging section 81 judges whether the vertical direction of the photo is correct (whether or not the rotation function is required) from the photo information table shown in FIG. . the

(2) Compare the number of pixels of the screen of the television 1 with the number of pixels of the photo. the

The display object attribute determination unit 81 compares the number of screen pixels (R5) of the television 1 shown in FIG. 7 with the number of picture pixels obtained from the “horizontal pixels” and “vertical pixels” shown in FIG. Whether the number is less than the number of screen pixels. the

(3) Determine whether the photo has a note. the

The display object attribute determination unit 81 determines whether or not a comment is stored in the “photo comment” shown in FIG. 21 . the

(4) Determine the copyright protection information of the photograph. the

The display object attribute judging unit 81 judges whether or not to apply a copyright protection lock to the photograph based on the "copyright protection information" shown in FIG. 21 . the

Then, the image analysis unit 82 acquires the identified photograph from the web album DB 8 and analyzes the photograph (S206). More specifically, the color tone of the photo is determined, and the display position of the object being photographed is determined. the

The operation option selection unit 83 selects operation options (functions provided to the television 1 ) to be displayed in the operation menu according to the determination result of the display object attribute determination unit 81 ( S207 ). the

The operation option selection unit 83 determines an operation option for adding a rotation function to the operation menu and its sub-operation options when it is determined that the top and bottom of the specified photo are incorrect according to the selection rule (column C4). The television 1 may be provided with a swivel function only if the swivel function is required. the

Also, when it is determined that the number of pixels of the photo is smaller than the number of pixels of the screen of the TV 1, an operation option of a screen size switching function (a function of enlarging the photo and displaying it in the full screen size of the TV 1) is added to the operation menu. Only when the size of the photo is smaller than the screen size of the TV 1 , can the enlarged display function be provided to the TV 1 . the

When it is determined that a photo has a comment, an operation option for the comment display function is added. When it is determined that the photo is not protected by a copyright protection lock, the operation option of the printing function is added to the operation menu. Therefore, when the copyright protection lock is attached to the photo displayed on the display screen, it is possible to control the television 1 so that it cannot be printed. the

In addition, the operation option selection unit 83 may be configured to select an operation option to be selected based on the content of the related information acquired by the related information acquisition unit 73 . For example, setting information (information for setting whether to always display the operation method screen 1103 like FIG. 11( a ) (“operation method display” in FIG. 8 )) is included in the display data request message as related information. the

When the operation option selection section 83 judges the content of the above-mentioned setting information "operation method display" and sets the operation method display to "No", it determines not to add the operation option of the operation method display function (or as a child of the operation option "other"). operation options). On the other hand, when the setting operation method is displayed as "Yes", it is determined to add the operation option. the

Therefore, the operation method display function is provided to the television 1 only when the requester's television 1 is set to "display the operation method screen". the

When the operation option selection unit 83 selects an operation option (function) to be included in the operation menu from the option selection rule storage unit 93 in S207, it provides the function ID of the selected function to the operation function definition generation unit 84 and the operation menu. Generate part 85. the

Then, the operation function definition generation part 84 extracts the script (operation function definition script) of column C6 from the function table (FIG. 23) of the operation function storage part 94 based on the above-mentioned function ID, and embeds it in the schema data, thereby generating the operation function definition. script (S208). The operation menu generation part 85 extracts the operation option name of column C5 based on the said function ID, embeds it in pattern data, and generates an operation menu determination script (S209). At this time, the display size, display position, display color, etc. of the operation menu are calculated, and the calculation results are embedded in the pattern data. the

The script synthesizing unit 86 synthesizes various scripts generated by the respective sections of the control script generating unit 80 to generate a control script (S210). the

The display data generating part 62 determines all required display objects, and extracts them from the Internet album DB 8 and/or the display object storage part 92 (S211), and synthesizes them with the control script generated above to generate the display data ( S212). the

The transmission unit 63b transmits the display data generated by the display data generation unit 62 as a response to the display data request message of the television 1 (S213). the

In the flowchart of FIG. 27 , the case of generating a slide show display screen for one photo included in an album is described, but when continuously generating slide show display screens for all photos included in an album, it is also possible to create a slide show display screen for each photo. The processing of S204 to S212 is repeated for one photo. the

According to the above-mentioned structure and method, the display data generation device 2 generates the optimal operation menu screen according to the display data requested by the television 1, and uses the functions corresponding to the operation options of the operation menu together with the data on the above-mentioned operation menu screen. Provided to TV1. The television set 1 that has received the above-mentioned display data can display the requested display screen (for example, a slide show display screen), and during the display process of the display screen, can execute a predetermined program according to the control script of the display data. Photo app features. the

That is, using the control script of the display data, for each display data (display screen) displayed on the television 1, the operation options of the operation menu to be displayed are selected, so that the functions executable by the television 1 can be individualized. change. the

By changing the control script and providing it to the television 1 as described so far, the functions of the television 1 can be easily changed. the

Changes involving the operation menu include: increasing or reducing the operation options of the operation menu; changing the presence or absence of a sub-operation menu and the number of sub-operation options for a certain operation option; changing the name of the operation option as required; and changing the name of the operation menu Display position, display color, etc. the

In addition, the television 1 can dynamically change the operation menu according to its own actions according to the control script. the

For example, the operation menu control unit 142 (FIG. 9) may dynamically change the operation option name of the operation option 1110 of the film advance control shown in FIG. "Automatic film advance start/stop" in the example of c)). the

In the control script, text data of two types of operation option names to be displayed in the operation option 1110 of the film advance control is prepared in advance. The first one is to indicate that the operation option of the function of starting the automatic film advance is named "automatic film advance start", and the second is that the operation option of the function of stopping the automatic film advance is named "automatic film advance stop". the

Moreover, in the case of displaying the operation menu 1104, when the television set 1 is automatically reproducing the slide show, it is preliminarily prepared in the above-mentioned control script to display the operation option name "automatic film advance stop" in the area of the operation option 1110. script, when the television 1 is stopping the automatic playback of the slide show, a script specifying the display operation option named "start of automatic film advance" is prepared in advance in the above-mentioned control script. the

Therefore, when the slide show execution control unit 141 presses the OK button (after the operation menu 1104 is called) while the slide show is being played back automatically, the operation menu control unit 142 displays a display including “ The operation menu 1104 of the operation option 1110a of "Auto Film Advance Stop". On the other hand, when the OK button is pressed when the slide show execution control unit 141 is stopping the automatic playback of the slide show, as shown in FIG. Operation menu 1104 . In this way, the television 1 can dynamically change the display of the operation menu 1104 according to the above-mentioned control script. the

Or, it is also possible to control the display method other than the operation menu (the icon 1101, the photo title 1102, the operation method screen 1103, etc. shown in FIG. Corresponding to the addition of a script defining the function of stopping the automatic reproduction of the slide show of photos contained in the album, a script for instructing a change of changing the icon 1101 indicating that the automatic reproduction is in progress to that indicating An icon 1109 during stoppage of film advance is automatically reproduced. the

Furthermore, by changing the operation of the television 1 when a predetermined event is detected in the control script, the functions of the television 1 can be easily changed. For example, for the photo rotation function, you can also add a sub-operation option that can rotate the photo 180 degrees each time instead of 90 degrees each time, or use the control script to arbitrarily change the time width of automatically displaying a photo in a slide show . the

Modification 1 - Change the display order of operation options

When the operation menu generating unit 85 of the display data generating device 2 generates the operation menu specifying script for displaying the operation menu, the display order of the operation options is determined according to predetermined conditions, thereby specifying the operation menu to display the operation options in this order. the

It is assumed that, for example, the display order of the operation options is determined according to the frequency with which the user utilizes each function. the

Every time the television 1 executes a function provided by the display data generating device 2 , it transmits menu use information indicating that the function is used to the display data generating device 2 . The function ID for identifying the function used is included in the menu use information. In addition, the above-mentioned menu usage information may include the terminal ID of the television 1, user information, and date and time information for using the function. the

In the function table shown in FIG. 23, the display data generating device 2 has a column for storing the number of times of use for each function. the

When the display data generating device 2 receives the menu use information from the television 1, the request message analyzing unit 70 acquires the function ID from the received menu use information, and specifies the function used by the television 1. The function use count management unit (not shown) of the control unit 60 adds 1 to the use count of the specified function in the function table of the operation function storage unit 94. In this way, the utilization count is stored for each function (operation option). the

Then, when the operation menu generation unit 85 generates the operation menu determination script, the operation menu generation unit 85 reads the usage count from the operation function storage unit 94 for each operation option selected by the operation option selection unit 83 . The operation menu generation unit 85 may generate the operation menu determination script so that the operation options are arranged in descending order of the number of times of use. the

FIG. 29( a ) and FIG. 29( b ) are diagrams showing an example of operation menu display before and after changing the display order of operation options. As shown in FIG. 29( a ), the television 1 previously displayed an operation menu 1104 with an operation option 1105 indicating "photo rotation" in front of the control script. At this time, the operation option 1111 of "photo list display" is displayed in the third place. the

Thereafter, the television 1 requests the data for displaying the slide show display screen from the display data generating device 2 again. The display data generation device 2 determines the display order of display options according to the frequency of use of each function at that time, and generates a new control script. At this time, if the function of "displaying a list of photos" is most frequently used by users, the operation menu generating unit 85 of the display data generating device 2 generates an operation menu determination script such that the operation option 1111 of "displaying a list of photos" is displayed on First. the

The television 1 displays an operation menu 1104 with the operation option 1111 of "photo list display" as the first one as shown in FIG. 29(b) according to the new control script including the operation menu determination script. the

In this way, the pattern of the operation menu can be dynamically changed according to the number of times the user uses the function, so that the operation options of the frequently used functions are located at an easy-to-select position (for example, at the top of the list). Thereby, it is possible to always provide the user with an operation menu that makes it easy to select frequently used functions. the

Alternatively, the display data generating device 2 may store, for each photo in the album, the number of times the photo has been requested and browsed by the user's television 1 . In this way, the display data generation device 2 can generate a control script for displaying the photographs so that popular photographs that are frequently browsed are decorated to make them stand out, or are marked and displayed. the

Modification 2 - focus movement

By using the control script, the operation menu control unit 142 ( FIG. 9 ) of the television 1 can be operated as follows. the

Specifically, the operation menu control unit 142 determines the focus position according to the information set in the television 1 and its own working state according to the control script. Then, the cursor is positioned at the determined focus position, and only the operation option is displayed in a conspicuous color (focus display processing). the

FIG. 30 is a diagram showing a specific example of a control script for the television 1 to execute in-focus display processing. As shown in Figure 30, when the (sub) operation menu is displayed, the control script stipulates: (1) read the setting information; (2) read the action of the slide show execution control unit 141; (3) make the cursor The (sub)operation item is located in accordance with the read content; and (4) the display color of the (sub)operation item where the cursor is located is changed to display the (sub)operation menu. the

The television 1 performs the above-mentioned operations (1) to (4) in accordance with the above-mentioned control script. the

Here, the process of performing focused display of the sub-operation menu after the main operation option is selected will be described in more detail. The operation menu control unit 142 of the display data execution processing unit 40 first reads setting information in accordance with the control script of FIG. 30 . The setting information refers to the setting information (column group C12 ) in the related information table stored in the related information storage unit 52 shown in FIG. 8 . If the example shown in FIG. 8 is used for description, then the operation menu control unit 142 reads out “remark display”=“proceed”, “operation method display”=“proceed”, “loop reproduction”= Values of "No", "Film Advance Interval" = "10 seconds". the

Then, the operation menu control unit 142 reads the operating state of the slide show execution control unit 141 and determines whether the slide show is being automatically reproduced or stopped. Here, it is determined that reproduction is in progress. the

Next, the operation menu control unit 142 determines a (sub)operation menu to be displayed on the display unit 15 based on the operation menu determination script. Then, determine the operation option consistent with the content read above, and place the cursor on the operation option. the

The operation menu control unit 142 changes the display color of the operation option where the cursor is located, and displays the operation menu. the

31( a ) to ( e ) are diagrams showing examples of sub-operation menus that are displayed in focus on the television 1 based on the control script described above. the

Fig. 31(a) shows an example of a sub-operation menu displaying the operation option of "remark display setting". In the above example, since the operation menu control unit 142 has read the value of "remark display" = "go", the sub-operation menu is displayed by specifying the sub-operation option of "display photo remark" as the focus position. the

Fig. 31(b) shows an example of a sub-operation menu in which the operation option "operation method display setting" is displayed. In the above example, since the operation menu control unit 142 has read the value of "display operation method" = "go", the focus position is determined as the sub-operation option of "display operation method" and the sub-operation menu is displayed. the

Fig. 31(c) shows an example of the sub-operation menu displaying the operation option of "loop reproduction". In the above example, since the operation menu control unit 142 has read the value of "loop playback" = "not performed", the sub-operation option of "no loop playback" is determined to be the focus position and the sub-operation menu is displayed. the

Fig. 31(d) shows an example of the sub-operation menu displaying the operation option of "automatic film advance interval". In the above example, since the operation menu control unit 142 has read the value of "film advance interval" = "10 seconds", the focus position is determined as the sub-operation option of "advance film at 10-second intervals" and the sub-operation menu is displayed. the

Fig. 31(e) shows an example of a sub-operation menu displaying the "automatic film advance start/stop" operation option. In the above example, since the operation menu control unit 142 judged that “the slide show execution control unit 141 is in automatic playback of the slide show”, it determined that the focus position was the sub-operation option of “Start automatic film advance” and displayed the sub-operation option. Action menu. the

In this way, by providing the above-mentioned control script to the television 1, the television 1 can display an operation menu focused on a predetermined operation option consistent with its content according to the information set in the television 1 and its own working state. the

Implementation mode 2

Background Technology and Issues

Conventionally, for an image display device that processes and displays large-capacity digital image data, the rendering process of rendering an image in an image buffer such as VRAM (Video Random Access Memory) and displaying it on the display unit is a high-load process. , and performing such rendering processing at a higher speed becomes a problem to be solved. the

Therefore, in order to perform rendering processing at a higher speed, efforts have been made to increase the speed of rendering processing by enriching hardware resources and configurations, or reducing the amount of processed data to reduce the load of rendering processing. the

For example, Patent Document 2 (Japanese Laid-Open Patent Publication: JP-A-6-149533 (published on May 27, 1994)) discloses that in the segment rendering method with double buffers, by omitting the The processing of a buffer, thereby enabling high-speed rendering processing graphics and display devices and their high-speed rendering methods. the

However, in the device of Patent Document 2, even if the information is partially updated, all the information (the amount of the entire screen) must be re-rendered, so there is a problem that useless information other than the part that needs to be re-rendered will be generated. Redraw processing. the

Therefore, Patent Document 3 (Japanese Laid-Open Patent Publication: JP-A-11-65813 (published on March 9, 1999)) discloses a rendering processing device capable of partially updating information and preventing delays in rendering processing. the

However, in the device of Patent Document 3, an application built in the device calculates a re-rendering area required for re-rendering. Therefore, the order in which the device calculates the re-rendering area cannot be dynamically changed according to the content of the information (display data), and the re-rendering area is calculated in a fixed order no matter what kind of information is re-rendered. Therefore, there is a problem that, for a certain piece of information, an area not intended by the information provider is included in the re-rendering area, resulting in useless re-rendering processing. the

Furthermore, if other information that does not need to be updated (particularly, objects with complex shapes, etc.) is partially included in the above-mentioned undesired re-rendering area, it is necessary to cut out the relevant part in the re-rendering area (clip processing). At this time, there is a problem that the more complicated the shape of the object to be redrawn in this part, the greater the load on the device for editing processing. the

In addition, in image display devices such as televisions and mobile phones, there are often restrictions on the design of hardware resources (restrictions on manufacturing costs, restrictions on the size of the device itself, etc.), and there are many ways to increase the speed of rendering processing without taking these into consideration. resources are unrealistic. In particular, for an image display device such as a television having a limited storage area, it is desired to realize more efficient re-rendering processing. the

Therefore, in the present embodiment, in the control script of the display data, the optimal reproduction of the display data is specified based on the content of the display data (display screen) displayed on the television 1 (FIGS. 1, 6, and 9). Depict the area. The so-called optimal re-rendering area refers to the minimum re-rendering area that does not require complicated processing. The television 1 can perform efficient re-rendering processing by determining an optimal re-rendering region in consideration of the contents of the display data according to the control script. Considering the contents of the display data means, for example, which object can be updated on the display screen, or whether the display position of the object is fixed or moving, etc., but is not limited thereto. the

Next, the television 1 and the display data generating device 2 (network album system 100 ) capable of specifying an optimum redrawing area and efficiently performing redrawing processing will be described. the

About the control script (redrawing the control script)

FIG. 32 is a diagram showing a specific example of a control script included in the display data ( FIG. 3 ) according to this embodiment. The example shown is that the control script in FIG. 32 includes: a layout definition script 112 that specifies three graphics for displaying a circle, a cloud, and a pop-up box; A case where the radius of the circle displayed above is changed from -50 to 100 and displayed when a predetermined signal (for example, '') is input to the operation unit 13 . the

In the layout definition script 112, the above-mentioned three figures are defined by sandwiching tags ("<" and ">"), respectively (script 112a). Image data or text data (or audio/video data) displayed on a display screen is defined by such a set of tags, and in the following description, regardless of the data format, it will be referred to as an object. the

As shown in FIG. 33( a ), the television 1 can display the above-mentioned three objects (circle 331 , cloud 332 , and pop-up box 333 ) on the display unit 15 according to the above-mentioned layout definition script 112 . the

Next, a re-rendering control script for determining an optimal re-rendering area and efficiently executing the re-rendering process will be described for the television 1 according to the present embodiment. the

The re-rendering control script constitutes a part of the above-mentioned control script, and is composed of the re-rendering area definition script 112b and the re-rendering area change script 113b. the

The redrawing area definition script 112b defines the area to be redrawn in a rectangular shape using the start point (X and Y coordinates) of the area and the width and height of the area. In addition, the object in the redrawing area is an object for the television 1 to determine the redrawing area. Since it is not an object that the user wants to see, as shown in FIG. The rectangle of the redrawing area is not displayed in (since the color is not set (specified as "none"), the user cannot see it regardless of whether the "visibility" of the display attribute is displayed or not). the

The re-rendering area change script 113b acquires the re-rendering area defined by the re-rendering area definition script 112b, and defines a change process to be performed on this part. In the example shown in FIG. 32, the redrawing area change script 113b stipulates that when the signal 'a' is input, the non-display setting is changed to display (change function "setTrait("visibility","visible");") . In this way, by defining change processing using the redrawing area change script 113b, the television 1 can judge the necessity of redrawing the redrawing area defined by the redrawing area definition script 112b at an appropriate timing. the

33(b) is a diagram showing an example display of the display unit 15 after the TV 1 executes the change process according to the operation content definition script 113 when a predetermined button of the operation unit 13 is pressed and a signal 'a' is input. The radius of the circle 331 is changed from 50 to 100 and displayed by the operation content definition script 113 . the

If the above-mentioned re-drawing control script is not described in the control script, then when the target object (circle 331) changes, the TV 1 will change the circumscribed rectangle of the target object (reticulate in the dotted line frame of FIG. 33 (c) area 334) is determined as the re-rendering area. Then, when an object (cloud 332 or popup 333 ) is partially included in the redrawing area, clipping processing (cutting out the portion of the object included in the redrawing area) is performed. For the calculation of the clipping area (the blacked-in portion in FIG. 33(c) ), the more complex the shape of the object is, the higher the load on the television 1 will be. the

In this embodiment, when the circle 331 is changed, the television 1 determines the rectangular area (hatched area 335 inside the dotted line frame in FIG. 33( c )) previously defined by the re-rendering control script as the re-rendering area. Therefore, since the target object (cloud 332 or pop-up frame 333 ) is completely contained (or not contained at all) in the redrawing area, clipping processing is not required. As a result, the redrawing processing efficiency of the television 1 can be improved. the

In this way, in order to avoid clipping of the object, it is desirable to define the redrawing area of the redrawing area definition script so as not to partially include the object. the

The display data generation device 2 that generates display data (consisting of control scripts and display objects) determines a redrawing area for all objects (graphics, photos, operation menus, text data, etc.) described in the control script, and makes the redrawing area The rendering area completely includes the target object or does not include the target object at all (so as not to include only a part of the target object), thereby generating a re-rendering area specifying script. That is, the display data generation device 2 calculates the minimum necessary re-rendering area based on the content (object position) of the display screen (display data) requested by the television 1, and designates such a re-rendering area The control script of is provided to TV1. the

Hereinafter, the configuration of the television 1 for re-rendering according to the above-mentioned re-rendering control script will be described in detail. the

TV structure 2-details

FIG. 34 is a block diagram showing the configuration of main parts of the television 1 according to the present embodiment. FIG. 34 is the same as FIG. 9 of Embodiment 1, and is a diagram showing the display data execution processing unit 40 of the television 1 shown in FIG. 1 in more detail. the

The TV 1 shown in FIG. 34 differs from that in FIG. 9 in that the control script execution unit 41 includes a change detection unit 144, a redrawing area determination section 145 , clipping section 146 , and rendering section 147 ; the storage section 50 has a redrawing area information storage section 55 . the

In addition, although not shown here, the control script execution unit 41 may include the slide show execution control unit 141 and the operation menu control unit 142 already described. the

Furthermore, the television 1 further includes the temporary storage unit 18 and the frame buffer 19 constituted by a volatile storage device such as a RAM as described above. the

The temporary storage unit 18 temporarily stores the display data fetched from the display data storage unit 51 and the display data processed by each part of the processing unit 40 . the

The frame buffer 19 temporarily stores display screen data for one screen to be displayed on the display unit 15 , which is generated after the processing of each part of the display data execution processing unit 40 is completed. The display screen data stored in the frame buffer 19 is drawn on the display unit 15 by the display control unit 24 and displayed so that the user can see it. the

The control script analysis unit 140 analyzes the control script as described above. Next, the function of the control script analysis unit 140 will be described in more detail. the

About the DOM tree

In this embodiment, more specifically, the control script analysis unit 140 has a function of developing a control script that is an XML document into a tree structure called a DOM (Document Object Model: Document Object Model) tree. A DOM tree defines the logical structure of an XML document. By expanding the control script into a DOM tree, the data in the control script can be processed for each object described by tags, and the relationship between objects can be identified. The advantage of the DOM tree is that desired objects can be accessed regardless of the order in which the control scripts are described. the

For example, the control script shown in FIG. 32 is expanded like the DOM tree shown in FIG. 35 . Such a DOM tree output by the control script analysis unit 140 is expanded on the temporary storage unit 18 of the television 1, and is read by each unit of the display data execution processing unit 40 as necessary. the

The change detection unit 144 detects a script that specifies change processing described in the control script (for example, a change function of the re-rendering area change script 113b, etc.), and determines the necessity of re-rendering processing for each object. the

When the change detection unit 144 detects a change processing script describing a process of changing an object being displayed and determines that redrawing of the object is necessary, it sets a changed flag on the object on the DOM tree. Setting the change flag indicates that the object needs to be redrawn. the

In the control script shown in FIG. 32 and FIG. 35, the change detection unit 144 detects the rectangle identified by ID='updatearea' (the hatched part in FIG. The circle identified by circle' (the circle 331 in FIG. 33( a )) is used as the object to be redrawn. Therefore, in FIG. 34, the change detection unit 144 sets change flags 341 for the rectangular object "rect" and the circular object "circle".

What the change detection unit 144 detects is not limited to the above-mentioned change function, and for example, an animated object may be detected. Only by changing the target object, the target object that needs to be redrawn can be detected correctly, and the target object that is the subject of change can also be detected under any conditions. the

The re-rendering area specifying unit 145 acquires information on objects whose change flags are set by the change detection unit 144 from the temporary storage unit 18 , and specifies the re-rendering area. the

Specifically, the re-rendering area specifying unit 145 scans the DOM tree ( FIG. 35 ) stored in the temporary storage unit 18 , and acquires the re-rendering areas of all objects for which the change flag 341 is set. The table that lists the re-rendering regions acquired by the re-rendering region specifying unit 145 is referred to as a re-rendering region list. The re-rendering area specifying unit 145 generates a re-rendering area list, and stores it in the re-rendering area information storage unit 55 . In addition, when the target object has a circular or other complex shape, a circumscribed rectangular area completely including the target object is calculated, and the calculated rectangle is added to the list as a redrawing area of the target object. the

When all the re-rendering regions are added to the list according to the DOM tree, the re-rendering region determination unit 145 scans all the re-rendering regions listed, and merges them into one if there are overlapping regions. That is, the circumscribed rectangles of all overlapping redrawing regions are calculated. the

FIG. 36( a ) is a diagram showing an example of a redrawing area list stored in the redrawing area information storage unit 55 . An example of a redrawing region list generated by the redrawing region specifying unit 145 based on the control scripts shown in FIGS. 32 and 35 is shown. the

A redrawing area list is generated for each control script constituting a display screen. In the examples shown in FIGS. 32 and 35 , since the change flag 341 is set for the rectangular object "rect" and the circular object "circle", the redrawing areas of these two objects are added to the list. In the redrawing area list, corresponding to the control script ID for identifying the control script of FIG. 32 and FIG. X and Y coordinates of the rectangle's starting point, width, height). the

Once the re-rendering area specifying unit 145 lists all object re-rendering areas for which the change flag is set, then merges the re-rendering areas that overlap each other. Then, finally determine one re-rendering area (or a plurality of them if they do not overlap), and determine it as the final re-rendering area. the

FIG. 36( b ) is a diagram showing an example of determined re-rendering area information stored in the re-rendering area information storage unit 55 . An example of combining the redrawing regions in Fig. 36(a) is shown. In the example of FIG. 36(a), since the listed re-rendering areas are overlapped as shown in FIG. 33(c), the circumscribed rectangular area 334 of the circle 331 and the predefined rectangular area 335 Combined to calculate a definite redrawing area. Also, since a plurality of definite redrawing areas may be calculated for one control script, each redrawing area can be individually managed using the redrawing area ID. the

Thus, the determined re-rendering area output by the re-rendering area specifying unit 145 is supplied to the rendering unit 147 that executes the re-rendering process on the determined re-rendering area. the

The rendering unit 147 performs re-rendering of the specified re-rendering area specified by the re-rendering area specifying unit 145 . The clipping unit 146 performs clipping processing. the

Specifically, first, the rendering unit 147 reflects the change processing result on the change target object (object provided with the change flag 341 ) in the identified re-rendering area, and writes the result to the temporary storage unit 18 . the

Then, the rendering unit 147 scans the DOM tree, and acquires a script defining the object as long as there is an object other than the change target partially included in the determined re-rendering area. This is because the information after the change cannot be correctly displayed unless the object is re-drawn even if it is included in the definite re-rendering area. Here, when the above-mentioned object is completely included in the determined re-rendering area, the above-mentioned object is written into the temporary storage unit 18 based on the acquired script. the

On the other hand, when the acquired object is partly included in the determined re-rendering area, the trimming unit 146 calculates the part of the object included in the determined re-rendering area, and sends it back to the rendering unit 147 as a clipping area. . The rendering unit 147 writes the clipping area acquired from the clipping unit 146 into the temporary storage unit 18 . the

In addition, the re-rendering area designated by the re-rendering control script can be defined by the display data generation device 2 according to the content of the display data as described above so that it does not partially include objects (especially objects with complex shapes). . Therefore, the determined re-rendering area calculated by the television 1 does not contain complex shapes, and high-load clipping processing can be avoided. the

As a result, all objects that need to be re-rendered in the determined re-rendering area are written to the temporary storage unit 18 . Finally, the rendering unit 147 renders the data written in the temporary storage unit 18 to the frame buffer 19 in the determined re-rendering area after the change process, and updates the data stored in the frame buffer 19 in the determined re-rendering area before the change process. The data. Then, the re-rendering of the determined re-rendering area is completed, and the changed new information is displayed on the display unit 15. the

According to the above configuration, when receiving display data including a re-rendering control script specifying a re-rendering area, the television 1 first displays an initial display screen in accordance with the control script of the display data. Then, when the change detection unit 144 detects that the displayed information has been changed, the re-rendering area determination unit 145 determines the re-rendering area according to the re-rendering control script included in the control script. The rendering unit 147 performs re-rendering in the determined re-rendering area specified by the re-rendering area specifying unit 145, and displays a new display screen reflecting the change. the

Here, the re-rendering area specified by the re-rendering control script is defined in advance based on the content of the display data as a re-rendering area that does not require complex processing and requires a minimum. That is, the fixed re-rendering area determined by the television 1 according to such a re-rendering control script does not partially include the target object. In this way, clipping processing of the object can be avoided, and only a minimum necessary area can be re-rendered. As a result, the re-rendering process can be executed efficiently. the

In addition, since the designation of the re-rendering area is realized by using the control script, the television 1 can always determine the optimal re-rendering area according to the content of the display data, so that the TV 1 can avoid the load of clipping processing and can always be high. Efficiently perform redrawing processing. the

Redraw the processing flow

FIG. 37 is a flowchart showing the flow of re-rendering processing in the television 1 . The re-rendering process is performed by the control script when the event processing unit 11 detects a predetermined event after the control script execution unit 41 ( FIG. 34 ) analyzes (expands into a DOM tree) and executes the control script of the display data to draw the initial screen. executed by each part of section 41. the

The re-rendering process generally consists of three steps. That is, the steps of the change detection unit 144 determining the necessity of re-rendering based on the re-rendering area change script; the steps of the re-rendering area determination unit 145 determining the re-rendering area based on the re-rendering area definition script; The determined re-rendering area is re-rendered. the

Next, the details of each step will be described. the

In the state where the initial screen is being displayed, when the event processing unit 11 detects a predetermined event (“Yes” in S301), the control script execution unit 41 and the event processing unit 11 execute the event according to the currently expanded DOM tree (control script). Processing of data for display (S302). When the change detection unit 144 detects a redrawing area change script such as a change function (or animation object) from the currently executing control script ("Yes" in S303), it sets a change flag to the detected change target object (S304 ). At this time, one or more objects to be changed may be detected. the

Then, the re-rendering area determination unit 145 generates a re-rendering area list for each object based on the change target object detected by the change detection unit 144. the

First, the re-rendering area determination unit 145 scans the DOM tree of the above-mentioned control script expanded in the temporary storage unit 18, and sequentially acquires objects (S305). Next, when the change flag is set on the acquired object (YES in S306), the re-rendering area of the object to be changed is calculated and added to the re-rendering area list (S307). Here, if the target area is defined as a rectangle, it is listed as it is, and if it is defined as a shape other than a rectangle, the circumscribed rectangle of the target is calculated and listed. The processing of S305-S307 is executed for all objects on the DOM tree. the

Next, the re-rendering area determination unit 145 finally scans the re-rendering areas added to the re-rendering area list, if there are overlapping re-rendering areas, merge them, and output the final determined re-rendering area to the rendering unit 147 (S308). the

Then, the rendering unit 147 writes all objects included in the determined definite re-rendering area to the temporary storage unit 18 to prepare display data for rendering in the frame buffer 19 . the

First, the rendering unit 147 scans the DOM tree expanded in the temporary storage unit 18, and sequentially acquires objects (S309). It is determined whether part of the obtained object overlaps with the determined re-rendering area (S310). Then, when it is determined that the object overlaps with the determined redrawing area (YES in S310 ), it is then determined whether the acquired object is an object to be changed with a change flag ( S311 ). the

When the drawing unit 147 determines that the object is a change target object (YES in S311 ), each part of the control script execution unit 41 executes change processing on the change target object according to the change script ( S312 ). Then, the changed object obtained by the change process is written to a predetermined area of the temporary storage unit 18 (S313). the

On the other hand, when it is determined in S311 that the object is not an object to be changed ("No"), the rendering unit 147 next determines whether the overlapping portion of the object and the determined re-rendering area is only a part or all (S314). Here, when it is determined that the acquired object completely overlaps the determined redrawing area ("No" in S314), the acquired object is written as it is to the predetermined area of the temporary storage unit 18 (S315). On the other hand, when it is determined that the acquired object partially overlaps with the definite re-drawing area (YES in S314), the clipping unit 146 calculates the overlapping portion of the target object and the definite re-drawing area (the clipping area). (S316). Then, the rendering unit 147 writes the clipping area of the acquired object to a predetermined area of the temporary storage unit 18 (S317). The processes of S309-S317 are executed for all objects on the DOM tree. the

Finally, the rendering unit 147 re-renders the data of the changed definite re-rendering area whose writing is completed from the temporary storage unit 18 to the definite re-rendering area of the frame buffer 19 . Then, the re-rendering of the determined re-rendering area ends, and the changed new information is displayed on the display unit 15 . the

As described above, the re-rendering area designated by the re-rendering area definition script is defined in advance based on the content of the display data as a re-rendering area that does not require complex processing and requires the minimum. That is, the determined re-rendering region determined by the re-rendering region specifying unit 145 according to such a script does not partially include objects of complex shapes. Therefore, it is possible to avoid clipping processing of an object having a complex shape, and to redraw only a minimum necessary area. As a result, the re-rendering process can be efficiently executed. the

In addition, since the designation of the re-rendering area is realized by using the control script, the television 1 can always determine the optimal re-rendering area according to the content of the display data, so that the TV 1 can avoid the load of clipping processing and can always be high. Efficiently perform redrawing processing. the

As described above, using the control script to designate the redrawing area on the display screen in advance is particularly effective for a display screen containing many complex-shaped objects and a display screen that undergoes many changes in response to events. the

Next, specific examples of the redrawing area specified in this way will be described using the examples in Fig. 38(a) to (i), so that clipping processing of complex-shaped objects can be avoided, and only the minimum required area can be redrawn. . If the television set 1 determines the re-rendering region according to the re-rendering region specified in FIG. On the other hand, compared with the case where the re-rendering area is determined, the re-rendering process can be performed more efficiently without the load of clipping processing. the

38( a ) to ( d ) are diagrams showing specific examples of a display screen including a complex-shaped object displayed on the display unit 15 . Changes that occur between the display screens in FIGS. 38( a ) to ( d ) and correspondences with events that cause the changes are also indicated by arrows. the

Figure 38(e)～(h) respectively illustrate the occurrence of Figure 38(a)→(b), (c)→(d), (a)→(c), (b)→(d) in the display screen The definite redraw area determined when the change of . Here, the determined re-rendering area shown in Fig. 38 (e) to (h) means that when there is no re-rendering area definition script, it is determined by using the re-rendering area calculated for each object that needs to be changed. Determine the repainting area. the

FIG. 38(i) shows the determined re-rendering area determined according to the re-rendering area definition script. the

FIG. 38( a ) is a display screen for displaying the weather (four) at regular intervals of the day, and the forecast of temperature and precipitation probability at each time, and shows an initial screen displayed by initially processing the data for display. The cursor 381 represents the weather forecast at four times of the day, focusing on the weather forecast icon at a future time closest to the initial screen display time among the four weather forecast icons 382 . The background cloud (object of complex shape) 383 is a pattern of the display screen, and is always placed behind various information of the weather forecast (all objects) on any screen. In addition, each weather symbol 384 within each weather forecast icon 382 is also an object with a complex shape that increases the processing load of clipping. the

When the yellow button provided on the operation part 13 is pressed in the state in which FIG. 38( a ) is displayed, it changes from FIG. 38( a ) to the display screen of FIG. 38( b ). That is, a 12-point detailed information popup 385 is displayed. Therefore, as shown in FIG. 38( e ), a region 380 e that is a circumscribed rectangle of the detailed information popup 385 is determined as a determined re-rendering region. the

When the right cross button provided on the operation unit 13 is pressed while FIG. 38( a ) is displayed, the display screen of FIG. 38( c ) is displayed. That is, the cursor 381 moves from the weather forecast icon 382 at 12 o'clock to the weather forecast icon 382 at 18 o'clock. Therefore, as shown in FIG. 38( g ), a region 380 g that is a circumscribed rectangle of the above-mentioned two weather forecast icons 382 is determined as a definite redrawing region. the

Similarly, when there is no re-rendering area definition script, since the circumscribed rectangle of each object that has changed is determined as the definite re-rendering area, each definite re-rendering area (areas 380e to 380h ) is displayed on any one of the display screens. , all partially contain complex-shaped objects such as the background cloud 383 or the weather sign 384, and as a result, a high-load editing process must be performed. the

Therefore, as shown in FIG. 38(i), the re-rendering area is designated by the re-rendering area definition script so as to completely include or not include complex-shaped objects, and to limit it to the required minimum area. As a result, the TV 1 can specify an optimal definite re-rendering region without partially including a complex-shaped object as shown in the region 380i according to the re-rendering region definition script. the

As a result, clipping processing can be avoided, and re-drawing processing can be performed efficiently. the

Modification 3 - Redrawing processing when the photo is rotated

In the above-mentioned example, the television 1 that avoids clipping processing and efficiently executes re-rendering processing based on a control script that designates a re-rendering area so that it does not partially include complex-shaped objects has been described. the

However, the control script is not limited to the above examples. The re-rendering area can also be designated by the control script, so that the object placed at the predetermined display position is always the object of the re-rendering process, regardless of the complexity of its shape, and it does not matter whether the object is an object to be changed. the

In this way, the following cases are specifically considered for the case where the designation of the re-rendering area inevitably occurs based on the display area of the object. the

When the display screen is changed, the following situation may occur: that is, due to hardware limitations, that is, the limit of the storage capacity of the temporary storage unit 18, in order to temporarily save the data generated during the change process, it is necessary to use the display screen actually output to the display unit 15 for saving. The area secured for the data (hereinafter referred to as the ARGB area). the

In this case, before rendering the display screen data output to the display unit 15 in the ARGB area, it is necessary to clear the area (dirty area) used for the change process in the ARGB area. the

However, it is not enough to just clear the dirty area. If there is an object in the area before the change, it is necessary to redraw the object (not the object to be changed) to restore it. Therefore, as described above, it is necessary to designate a redrawing area so that redrawing can be accurately performed on an object involved in the change process (an object overlapping with a dirty area during the change process). the

Next, taking the case where the change processing (S312 in FIG. 37) is the photo rotation processing (S115 in FIG. 10) as an example, the display area of the object and the area that is dirty (presumably dirty) during the photo rotation processing A description will be given of the television 1 that executes the re-rendering process in accordance with a control script that designates a re-rendering area. the

Problems when rotating photos

The structure of the staging department

FIG. 39 is a block diagram showing the configuration of main parts of the television 1 (particularly, the temporary storage unit 18 ) that executes the photo rotation process. As described in Embodiment 1, the photo rotation control unit 143 executes photo rotation and display processing according to the control script. More specifically, the photo rotation control unit 143 implements the following operations: that is, using the temporary storage unit 18 as a work area, acquires a photo to be rotated from the display data storage unit 51, rotates the acquired photo, and converts the rotated The rotated photo is sent to the frame buffer 19 so that the rotated photo is displayed on the display unit 15 . the

The photo rotation control unit 143 serves as the temporary storage unit 18 of the work area, and has an ARGB area 181 , a spare area 182 , and a YUV area 183 . The above three areas are fixed by hardware in the temporary storage unit 18 . the

The YUV area 183 is an area for temporarily storing JPEG photographs received in YUV format and stored in the display data storage unit 51 . the

The ARGB area 181 and the spare area 182 are areas for temporarily storing the JPEG photograph in the YUV format stored in the YUV area 183 into the ARGB format. the

The ARGB area 181 is an area for storing display screen data actually output to the display unit 15 . Display image data output to frame buffer 19 must be provided by ARGB181. The spare area 182 is an area used as a spare area for the work area when the control script execution unit 41 performs change processing such as rotation on the photograph converted into the ARGB format. the

In addition, the so-called YUV format refers to a format in which a color is represented by three pieces of information: a luminance signal (Y), a difference between the luminance signal and a blue component (U), and a difference between a luminance signal and a red component (V). Since a large amount of data is allocated to the luminance signal, a high data compression rate can be obtained with a small amount of image quality degradation, which is an advantage of using the YUV format. the

Therefore, when a photo is included in the display data and supplied from the display data generating device 2, the photo is always in the YUV format. Therefore, since it needs to be converted into an RGB format (ARGB format) for display on the display unit 15, after the photo is expanded in the YUV area 183 by the control script execution unit 41, it is converted into the ARGB format, and is displayed in the ARGB area 181 or the spare area. After being expanded in 183, it is sent to the frame buffer 19. the

The state of the ARGB area and the preparation area when the photo is rotated

Next, the ARGB area 181 and the spare area when the photo rotation control unit 143 rotates a photo will be described with reference to FIG. 182 status and problems in this case. the

FIG. 40( a ) shows the state of the ARGB area 181 and the spare area 182 at the time of initial drawing. In the ARGB area 181 , data of the display screen currently being displayed on the display unit 15 (the circular object 190 , the vertical photograph 185 , and the background) are stored. No data is stored in the spare area 182 . Alternatively, some data may remain from other operations. the

Here, when an instruction to rotate the vertical photo 185 by 90 degrees is input, the photo rotation control unit 143 executes photo rotation processing. Therefore, first, as shown in FIG. 40( b ), the vertical photo 185 converted into the ARGB format in the ARGB area 181 is called out and temporarily stored in the ARGB area 181 . Then, as shown in FIG. 40( c ), a photo obtained by rotating the temporarily stored vertical photo 185 by 90 degrees is temporarily stored in the spare area 182 as a horizontal photo 186 . Then, as shown in FIG. 40( d ), the dirty area (ie, the area temporarily used during the rotation process) 188 of the ARGB area 181 is cleared. Then, the photo rotation control unit 143 determines the re-rendering area, and re-renders the changed (rotated) display screen. the

At this time, in the case where the re-rendering area definition script is not specifically designated, according to the above-mentioned flow, the television 1, as shown in FIG. ) area is determined as a re-rendering area, and the circumscribed rectangles of these areas are determined as a re-rendering area (determined re-rendering area 184). the

Once the re-rendering area 184 is confirmed, as shown in FIG. Next, the photograph rotation control unit 143 detects the circular object 190 partially overlapping the determined re-drawing region 184 determined as described above. Then, as shown in FIG. 40( f ), the clipping unit 146 cuts out the area to be redrawn, and writes the clipping area 187 of the circular object 190 into the ARGB area 181 . The display screen data stored in the ARGB area 181 is output to the frame buffer 19 and displayed on the display unit 15 . the

In this way, if the re-rendering area is not designated by the re-rendering area definition script so as to completely include the above-mentioned circular object 190, the horizontal photo 186 and the circular object 190 must be displayed originally as shown in FIG. 40(h), but The left side of the above-mentioned circular object 190 is displayed without being restored, and there is a problem that the photo rotation process cannot be performed correctly. the

In order to solve the above problems, it is necessary to change the control script provided to the television 1 . Specifically, as long as it is known from the dirty area 188 shown in FIG. 40(d) that it is an area that has been previously dirty due to predetermined processing, use the re-rendering area definition script to specify that all objects overlapping with the dirty area are completely included. Such a redrawing area is sufficient. the

In addition, in this embodiment, since the called photo must be drawn from the upper left, the dirty area 188 can be determined according to the starting point coordinate (X, Y)=(0, 0) and the size of the photo. That is, a control script specifying the region 189 as a redrawing region is provided to the television 1 . the

FIG. 41 is a diagram showing an example of a control script for designating a redrawing area based on the circular object 190 and the area 189 used in the photo rotation process. The re-rendering area definition script 112c is a script for specifying the area 189 as a re-rendering area, and the re-rendering area change script 113c is a script for making the change detection unit 144 recognize the specified re-rendering area as an object to be changed. the

Photo rotation processing flow

FIG. 42 is a flowchart showing the flow of photo rotation processing executed by the photo rotation control unit 143 as the change processing in S312 of FIG. 37 . In addition, it is assumed that the re-rendering area specifying unit 145 specifies the area 189 in FIG. 40(i) as the determined re-rendering area in S308 of FIG. 37 . Hereinafter, the object judged to be the object to be changed in S311 of FIG. 37 is referred to as a photo to be rotated. the

The photo rotation control unit 143 determines whether the rotated data of the photo to be rotated is stored in the spare area 182 (S401), and if it is determined that it is not stored ("No" in S401), then it is determined whether the above-mentioned rotated data is stored in the YUV area 183. Object photo (S402). When the photo rotation control unit 143 determines that the photo to be rotated is stored in the YUV format in the YUV area 183 (YES in S402), it converts the photo to be rotated from the YUV format to the ARGB format, and stores it in the ARGB area 181. Expand (S404). On the other hand, when it is determined that the photo to be rotated is not stored in the YUV area 183 (No in S402), the photo rotation control unit 143 writes the photo to be rotated stored in the display data storage unit 51 into the YUV area. 183 (S403), and then execute the step of S404. the

Then, the photo rotation control unit 143 rotates the photo to be rotated stored in the ARGB area 181 at an angle determined by the control script, draws the rotated photo in the spare area 182 (S405), and returns to the determination of S401. the

In S401, when it is determined that the rotated data of the photo to be rotated is stored in the spare area 182 ("Yes"), the photo rotation control unit 143 clears the fixed re-rendering determined by the re-rendering area determination unit 145 in the ARGB area 181. area (S406). the

Finally, the photo rotation control unit 143 writes the rotated photo to be rotated temporarily stored in the spare area 182 into the ARGB area 181 ( S407 ), and ends the photo rotation process. the

Afterwards, as already described in Fig. 37, if there are other objects (circular object 190 in the example of Fig. , write it into the ARGB area 181 , and output the updated determined re-rendering area in the ARGB area 181 to the frame buffer 19 . the

As described above, even when it is necessary to use the temporary storage area (ARGB area 181) in which the display screen data should be stored during the change process, an optimal control script can be generated based on the content of the display data and provided to the television 1. , and the optimal control script only needs to designate the area known to be pre-dirty due to the change process and the re-rendering area completely including the object overlapping with the dirty area. the

The television 1 can accurately determine the object that needs to be re-rendered and perform the re-rendering even if it is an object other than the target object to be changed according to the re-rendering area specified by the above-mentioned control script. the

As can be seen from the above, even when the storage capacity of the temporary storage unit 18 is limited, it is possible to realize the television 1 capable of performing modification processing on large-capacity digital image data and displaying it. the

In addition, in the above explanation, the case where the photo format is assumed to be JPEG has been explained, but the format that can be displayed on the TV 1 is not limited to JPEG, and bitmap, PNG (Portable Network Graphic: Portable Network Graphics) and the like can also be displayed. Photos and images in various formats. In addition, when whether or not rotation processing can be applied differs depending on the format, the photo rotation control unit 143 may be configured in such a way that it determines the format of the photo to be rotated, and performs photo processing only for photos in a format that can be rotated. Rotation processing. the

Variation 4 - Redrawing during preloading

In the above example, an example was described in which an area to be redrawn is partially designated based on the content of display data (area dirty by the change process and object involved in the change process). However, the redrawing area definition script specifying the redrawing area is not limited to this, and a redrawing area definition script specifying the entire screen as the redrawing area may be provided to the television 1 as necessary. the

As described above, when the television 1 acquires display data (first display data), the first control script included in the first display data is expanded into a DOM tree and written into the temporary storage unit 18 (preloading). . Then, when the display data is displayed for the first time, since there is no previous rendering data, rendering is performed on the entire screen regardless of the re-rendering area. the

Afterwards, when the first display screen is changed, the above structure and method are used to re-render only the determined re-rendering area which is the difference from the last rendering data. the

However, even when displaying another display screen, that is, displaying a second display screen different from the above-mentioned second display screen according to the second control script of the second display data, the DOM tree of the above-mentioned first control script will be generated in the television 1. The status is stored in the temporary storage unit 18 as it is. the

In this case, when the preloaded first display data is displayed once, the second display data is displayed, and then the first display data is displayed again, it may be determined that there is no redrawing area. Assume that this is the case where the change script detected by the change detection unit 144 (animated object, change function, etc.) is not included in the first control script of the first display data. Alternatively, it is assumed that even if such a change script exists in the first control script, only a part of the entire screen is specified as the re-rendering area. the

As described above, when it is determined that there is no redrawing area or only part of the redrawing area is determined, regardless of whether an event for returning from the second display screen to the first display screen is detected, the display screen does not change from the second display screen to the first display screen. The screen transitions to the first display screen or only a part of the display screen returns to the first display screen, etc. The problem that the display screen transition cannot be performed correctly. the

In this case, it is necessary to designate the re-rendering area as the entire screen so that the entire screen returns from the second display screen to the first display screen. the

Therefore, when processing display data for a display screen different from the display screen displayed so far, a redrawing area definition script specifying the redrawing area as the entire screen is included in each control script and provided to the television 1 . the

Thus, in the television 1, when the event processing unit 11 detects the input of a signal instructing to return from the currently displayed second display screen to the previously displayed first display screen, the control script execution unit 41 displays the first The first control script for the display screen determines the entire screen as the determined re-rendering area, and re-renders the entire screen of the first display screen. Therefore, even when returning to the original display screen from a different display screen, screen transition can be accurately performed. the

As described above, by describing the re-rendering control script in the control script based on the content of the display data and providing it to the television 1, the re-rendering area desired by the author of the display data (display data generating device 2) can be specified. By describing in the control script, you can always specify the area you want to update, or you can always not specify the area you don't want to update. the

In addition, for an animation object detected by the change detection unit 144 as a change object, the redrawing area required for the movement of the object may be used as a circumscribed rectangle of the object so that the TV 1 can determine the control script. . the

Also, the shape of the redrawing area is not limited to a rectangle. Any graphics may be used as long as they are simple graphics that do not require complicated clipping processing. For example, a redrawing area having a shape such as a hollow rectangle like a frame, a circle, or an ellipse may be defined in the control script. the

Implementation mode 3

In the description of Embodiment 1 above, a case was described in which a control script is generated based on the content of display data, an operation menu to be displayed is appropriately changed, and a photo application function corresponding to the operation menu is provided to the television 1 . the

Each photo application function that provides the control script to the television 1 is described in an operation function definition script such as scripts 132a to 132d in FIG. 12 included in the control script, for example. When (definition of event) and how to do (definition of function to be executed) are described in the operation function definition script. As described in Embodiment 1, the photo application function of the television 1 can be flexibly changed by changing the defined part of the function to be executed according to the content of the display data. the

Furthermore, as shown in FIG. 12 , the definition of a function to be executed corresponds to the definition of an event that triggers the television 1 to execute the function. These events are often detected by the event processing unit 11 when the user presses various buttons provided on the operation unit 13 . For example, since script 132a describes as

if(evt.data=='y'),

Therefore, it indicates that the function of displaying/not displaying the operation menu defined by the script 132a is executed in response to pressing of the yellow button ('y' indicates a signal input through the yellow button) of the operation unit 13 . That is, the yellow button (event) corresponds to the function of display/non-display of the operation menu. the

In this embodiment, a case will be described in which the operation of the television 1 operated by the operation unit 13 is controlled by appropriately setting combinations of buttons (events) and functions of the operation unit 13 in the operation function definition script. In this way, different functions can be assigned to the same button for each display data, or the same function can be assigned to different buttons for each display data. the

In the display data generating device 2 that generates a control script, among these combinations of buttons and functions, an optimal combination is selected according to the contents of the display data when generating the control script. That is, since the operation function definition script is always generated in consideration of the operability of the user regardless of the display data to be displayed on the television 1 , the operability of the user on the television 1 can be maintained. the

In addition, the display data generation device 2 may generate an operation function definition script by changing the combination of the above-mentioned buttons and functions in response to a request from the television 1 . For example, the TV 1 sends an instruction to the display data generating device 2 (the user may also perform the operation on the TV 1) so that it can respond to the OK button, and the execution has so far been performed in response to the yellow button. action of some kind. The display data generating device 2 can generate an operation function definition script by associating the above-mentioned function with the OK button instead of the yellow button based on the instruction. the

Fig. 43 is a diagram showing an example of an operation function definition script. In the script 431, an event of "when the OK button (of the operation unit 13) is pressed" is defined. 'k' indicates a signal input via the OK button. the

Further, after the script 431, a function to be executed by the control script execution unit 41 of the television 1 when the OK button is pressed is defined. Here, as an example, it is defined that when the TV 1 is displaying the display screen of FIG. 11( b ), when it is detected that the OK button is pressed, the operation menu control unit 142 displays the display screen of FIG. 11( c ), that is, the sub-operation Functions of the menu 1106 . the

Here, it is assumed that the display data generation device 2 changes the script 431 of the operation function definition script shown in FIG. 43 into

if(evt.data=='d')

Then provided to the TV 1. In this case, when the right cross button is pressed instead of the OK button, the television 1 displays the sub-operation menu 1106 . 'd' indicates the signal input via the right cross button. the

As described above, in the operation function definition script, by changing the combination of buttons and functions, that is, changing the definition of events, it is possible to control the television 1 to execute the same function by inputting different buttons. the

In addition, the television 1 can display a display screen (transition screen) different from the display screen currently being displayed in response to a button being pressed according to the state transition definition script. In the state transition definition script, describe the transition target information to determine which display screen to transition to when an event occurs. Therefore, in the state transition definition script, the combination of the button and the transition destination information may be changed, for example, as described below. the

44( a ) and ( b ) are diagrams showing the transition of the display screen when the OK button is pressed. the

As shown in FIG. 44( a ), when the TV 1 detects that the OK button is pressed while the album history screen 440a is being displayed, it acquires a slideshow display screen 440b (first, the title screen of the album) and displays it. On the operation method screen 1103 of the album history screen 440a, an explanation for transitioning to the slideshow display screen 440b (title screen) by the OK button may be displayed. the

In this case, in the state transition definition script, the OK button is associated with the transition destination information for transitioning to the slide show display screen 440b. the

As shown in FIG. 44( b ), when the television 1 detects that the OK button is pressed while the album history screen 440a is being displayed, it acquires and displays a thumbnail display screen 440c. In this case, unlike FIG. 44( a ), an explanation for transitioning to the thumbnail display screen 440 c by pressing the OK button may be displayed on the operation method screen 1103 . the

In this case, unlike FIG. 44( a ), in the state transition definition script, an OK button is associated with transition destination information for transitioning to the thumbnail display screen 440c. the

Therefore, even if the same button is pressed, the display screen to which the television 1 transitions can be changed. the

Furthermore, the television 1 can also describe a state transition definition script so that when the same button is pressed, the transition target is changed according to a predetermined condition. According to the example shown in Fig. 44 (a), (b), by using the state transition definition script that describes the condition, the TV 1 with the following functions can be realized: that is, for example, in the album history screen 440a through the OK button In the case of selecting an album, it is determined whether to transfer to the slide show display screen 440b of the album or to the thumbnail display screen 440c according to the number of photos contained in the selected album. the

Fig. 45 is a diagram showing a specific example of a state transition definition script when describing a condition. Let this state transition definition script correspond to the OK button. In the state transition definition script shown in FIG. 45 , in order to make the control script execution unit 41 of the television 1 perform condition determination, determine the transition target according to the condition and display the display screen of the transition target, the following necessary information is described. the

The script 451 defines a method for acquiring information to be judged (here, the number of photos in the selected album). The control script execution unit 41 acquires information on the number of photos in the selected album from a predetermined file (top.svg) according to the script 451 . In addition, in this embodiment, the above-mentioned file is generated by displaying a value of "10" if the number of album photos is 10 or less, and a value of "11" if it is more than 11, as a photo sheet number information. The above-mentioned file only needs to be described in the same control script together with the state transition definition script so that it can be identified by the name "top.svg". In addition, the above-mentioned file is generated by the display data generating device 2 . Specifically, the display data generating device 2 refers to the album information table shown in FIG. 20 , and generates the file by including the value "10" or "11" in the file according to the number of photos in the requested album. the

The script 452 defines a method for judging the information to be judged (here, information on the number of photographs acquired from the file). According to the script 452, the control script execution unit 41 judges whether the photo number information is "10" or "11". the

Script 453 defines decision conditions. In the example shown in FIG. 45 , the case of the number of photographs information is divided into "10" and "11", and the name of the script defining the function to be executed by the control script execution unit 41 ("cpm_title", "cpm_thumbnail"). the

The script 454 defines functions to be executed by the control script execution unit 41 according to each determination condition. That is, the control script execution unit 41 can obtain and display the slide show display screen 440b according to the script "cpm_title" when (1) the photo number information is "10" (10 or less); and (2) When the photo number information is "11" (11 or more), according to the script "cpm_thumbnail", the thumbnail display screen 440c can be acquired and displayed. the

Therefore, the state transition definition script is described by defining the conditions and the function of each condition. When a button is pressed, according to the predetermined condition, the TV 1 can be controlled to select an appropriate action from a plurality of actions and implement. the

As described above, using the control script, it is possible to easily change the correspondence between each button provided on the operation unit 13 and the function of the television 1 assigned to the button. the

Implementation Mode 4

By using the control script, the following functions executed by the television 1 can be controlled. the

(1) Control of data acquisition function for display

The television 1 transmits a display data request message requesting desired display data to the display data generating device 2 , and acquires the requested display data from the display data generating device 2 . the

The display data acquisition function of the television 1 can be controlled by defining when and which display data to acquire on the side of the display data generation device 2 in the control script. the

For example, assume that there is a case where the second display screen of the second display data is always displayed after the first display data of the first display data is displayed. At this time, if the control script of the first display data describes the acquisition of the second display data, the television 1 can perform the process of displaying the first display screen of the first display data according to the above control script, And acquire the above-mentioned second display data. the

Here, it takes a certain amount of time until the television 1 requests display data from the display data generating device 2 through the communication network until the requested display data is acquired. Therefore, when an instruction to display the display data is received from the user, the process of acquiring and displaying the display data is started, and this operation cannot respond quickly to the user's instruction, thereby impairing the user's convenience. the

Therefore, when the display screen (display data) to be displayed next can be predicted, the television 1 acquires the next second display data in advance while processing the first display data according to the above-mentioned control script. Therefore, when a user's instruction is input, the next display screen can be displayed immediately based on the display data acquired in advance and stored in the device. Thereby, the response speed of the display data display process can be improved, and the user's convenience can be maintained. the

(2) Control of data management functions for display

The television 1 uses the display data storage unit 51 to manage the display data acquired from the display data generation device 2 . Specifically, in response to an event detected by the event processing unit 11 , the display data is stored in the display data storage unit 51 , or is determined to be unnecessary and deleted from the display data storage unit 51 . the

By defining how to manage the display data in the control script, it is possible to control the display data management function in the display data storage unit 51 of the television 1 . For example, the following cases are defined: that is, the acquired display data is saved so as not to be deleted from the display data storage unit 51; section 51; and the predetermined display data stored in the display data storage section 51 is deleted; and the like. the

As described above, since it takes a certain amount of time to acquire display data from the display data generating device 2 , it is preferable to store frequently used (displayed) display data in the display data storage unit 51 . the

Therefore, when the display data generation device 2 transmits the display data commonly used in the television 1 to the television 1, it includes a control script that defines the storage of the display data so that it will not be displayed from It is deleted by the data storage unit 51 . the

According to the above control script, the television 1 can always save frequently used display data in the display data storage unit 51, thereby reducing the communication amount with the display data generating device 2 and improving the response speed of display data display processing. the

For each piece of display data, the display data generating device 2 may count the frequency of use of the display data in the television 1, determine a storage method of the display data according to the frequency of use, and generate a control script. Every time the television 1 uses (displays) the display data, it transmits display data use information to the display data generating device 2 . The display data generating device 2 can store the display data usage information transmitted from the television 1, and manage the usage frequency for each display data. the

In addition, since the configuration of the control script generated by the display data generation device 2 according to the frequency of use is the same as the configuration described in "Modification 1 - Changing the display order of operation options" of the first embodiment, its description is omitted here. the

Implementation Mode 5

Modification 5 - Adding visual and auditory effects when displaying thumbnails/slideshows

In the network album system 100 of the present invention, the display data generation device 2 can also add the following functions to the television 1 by providing the control script to the television 1 . That is, a function of outputting visual effects and auditory effects according to the contents of the display screen (albums and photos) being displayed on the television 1 . the

The control script generating part 80 of the display data generating device 2 can also generate a control script defining an output effect or an action of a sound, so that when the TV 1 displays an album, visual ( and hearing) effects. The so-called effect refers to the visual effect added to the target when the target is displayed (or not displayed) (for example, a photo of an album displayed in a slide show, etc.). Specifically, various effects such as fade-in (fade-out), slide-in (slide-out), enlargement, and blinking are conceivable. In addition, effects such as adding animation such as a panning screen to objects (persons, etc.) other than photographs, or zooming, panning, or scrolling of people are also included in the effects. the

In this embodiment, for example, as shown in FIG. 20 , audio file information is managed for each album and effect information is managed for each photo in the album information table. the

The column of "sound file name" indicates the file name of the sound file related to the album. The sound file is output as a sound (music, effect sound, etc.) when the TV 1 displays a photo album in thumbnail or slide show. the

The "effect ID" column indicates an effect ID for identifying an effect associated with each photo included in the album. The display data generating device 2 describes the operation of the television 1 related to the above-mentioned effects in the control script so that the television 1 executes the effect specified by the effect ID. the

Fig. 46 is a block diagram showing the configuration of main parts of the display data generation device 2 for generating display data with added visual and auditory effects. The difference with the display data generation device 2 of FIG. 18 is that the control script generation part 80 also includes a sound determination script generation part (control script generation unit) 87 and an effect definition script generation part (control script generation unit) 88; The unit 90 further includes an audio file storage unit (effect information storage unit) 95 and an effect information storage unit (effect information storage unit) 96 . the

The audio specifying script generation unit 87 generates an audio specifying script including link information of an audio file to be output together with the display of the album. The effect definition script generation unit 88 generates an effect definition script executable by the television 1 based on the effect definition information stored in the effect information storage unit 96 . the

The audio file storage unit 95 stores audio files. The sound files are stored in a file format that the television 1 can handle, such as midi format. The television 1 acquires the above-mentioned audio file from the display data generating device 2, and outputs it to the audio output section 17 ( FIG. 1 ) through the audio output control section 25 . the

Alternatively, the display data generating unit 62 may include an audio file in the display data 7 and supply it to the television 1 . the

The effect information storage unit 96 stores effect definition information defining effects. FIG. 47 is a diagram showing an example of an effect definition script stored in the effect information storage unit 96 . the

In the example shown in Fig. 47, six columns are prepared for each effect. the

"effectID" in the column C21 indicates the above-mentioned effect ID. Column C22 represents the effect name. For example, the effect name "Fill-opacity" indicates an effect of changing the opacity of an object (here, a photograph). the

"dur" of the column C23 indicates the time (seconds here) to apply the effect. For example, when expressed as 3 seconds, it means that the effect (opacity change) is applied for 3 seconds. the

"from" in the column C24 indicates the initial value of the object. Specifically, represents the opacity of the photo before the effect is applied. When "from" is expressed as 0.8, it means that the photo will start to be displayed at an opacity of 0.8. Furthermore, the smaller the opacity value, the more transparent it is. the

"to" in the column C25 indicates the final value of the object. That is, represents the opacity of the photo after the effect has been applied for "dur" seconds. When "to" is expressed as 0, it means to change the photo to an opacity of 0. the

"end" in the column C26 indicates a key (button) assigned a function of interrupting the operation of the effect in the television 1 . The value of "end" is determined for one key provided on the operation unit 13 of the television 1 shown in FIG. 1 . When the key of the operation part 13 determined by "end" is pressed while the TV 1 is executing the effect, the TV 1 stops executing the effect. the

For example, when the effect of the effect ID "effect00" shown in Figure 47 is applied to a photo, when TV 1 performs a slide show to display the above photo according to the content of the effect definition script, the opacity can be reduced within 3 seconds. Varies from 0.8 to 0 for display. Then, in that case, the effect can be interrupted when the "y" button (yellow button) is pressed due to user action. the

In the example shown in FIG. 47, three kinds of effect definition scripts are shown, but the present invention is not limited thereto, and various effect definition scripts may be stored. the

The television 1 can execute the above-described actions in accordance with the operation function definition script 132 described in the operation content definition script 113 (FIG. 3). the

Next, the operation of the display data generating device 2 for generating a control script with added visual and auditory effects will be described in detail. Next, a case where the display data generating device 2 generates the display data 7 for slide show display in response to a request from the television 1 will be described as an example. However, it is not limited thereto, and the display data 7 with added visual and auditory effects may be generated in the case of thumbnail display. the

FIG. 48 is a flowchart showing the flow of processing for generating display data by the display data generating device 2 according to the present embodiment. The difference between Fig. 48 and Fig. 27 is that: before the script synthesizing section 86 synthesizes in S210, the sound determination script generation section 87 of the control script generation section 80 generates a sound determination script, and the effect definition script generation section 88 generates an effect definition script; and The display data generating unit 62 extracts a sound file in addition to the object to be displayed in S211. In addition, in S201 to S213, except for the point that the extracted audio file is also synthesized into the display data, the processing is the same as that of FIG. 27 , so the description will not be repeated here. the

FIG. 49 is a schematic diagram showing an example of a layout definition script 112 ′ and a layout definition script 112 respectively included in the pattern data 171 and the control script 110 stored in the pattern data storage unit 91 according to the present embodiment. the

In this embodiment, in the pattern data 171 acquired by the pattern data selection unit 61 of the display data generation device 2 from the pattern data storage unit 91, the layout definition script 112' further includes an image determination script 274, album basic information 275, and sound OK script 279. Also, the image specifying script 274 includes an effect pattern 274a as a prototype of the effect corresponding to the slide show photo. the

Also, image specifying script 274 ( 284 ) and sound specifying script 279 ( 289 ) are specific examples of display object specifying script 121 , and album basic information 275 ( 285 ) is a specific example of attribute information specifying script 123 . the

After S209 (FIG. 48), the control script generating unit 80 embeds the sound file name (that is, the link information of the sound file) in the sound specifying script 279 shown in FIG. 49 to generate the sound specifying script 289 (S209a). Based on the album ID (and photo ID) acquired by the display object ID acquisition unit 71, the audio file name to be embedded is extracted from the album information table stored in the network album DB 8 . For example, in the example shown in FIG. 20 , when it is determined that the first photo in the album with the album ID "0125478225142584" is to be displayed as a slide show, the control script generator 80 extracts the sound file name "bgm1.midi" according to the album ID, The link information of the sound file is embedded in the sound specific script 279 . The television 1 can obtain and reproduce the audio file "bgm1.midi" from the display data generating device 2 during the slideshow display based on the audio definition script 289 thus generated. the

Next, the control script generating unit 80 embeds the attribute information of the effect in the effect schema 274a, and generates the effect definition script 284a (S209b). the

FIG. 50 is a diagram showing a specific example of the effect schema 274a and the effect definition script 284a shown in FIG. 49 . Portions sandwiched by "_" and "_" respectively correspond to attribute information of effects in the effect definition script table shown in FIG. 47 (columns C21 to C26). That is, the control script generating unit 80 extracts six types of attribute information specifying effects from each column, and embeds them in the part of "_***_", thereby generating the effect definition script 284a. the

It will be specifically described using the example of FIG. 20 described above. According to the display data request message 6 of the television 1, it is determined that the first photo (photo ID=No. 1) of the album of the album ID "0125478225142584" is to be displayed in a slide show. The control script generating unit 80 specifies effects based on the above-mentioned album ID and photo ID. In the above example, since the above-mentioned album ID and photo ID are associated with the effect ID "effect00", the effect of the effect ID "effect00" is determined as the effect added to the above-mentioned photo. the

Next, the control script generation unit 80 extracts the attribute information of the effect from each column of the effect definition script table in the effect information storage unit 96 based on the specified effect ID. The control script generating unit 80 embeds each piece of extracted attribute information in a corresponding position, thereby generating the effect definition script 284a. In the effect definition script 284 a of FIG. 50 , it is described that the opacity of the white rectangle overlapping with the photograph, which is the object, is changed from 0.8 to 0 within 3 seconds. Then, when the yellow key (key (y)) of the operation unit 13 of the television 1 is pressed, a function of interrupting the change process is assigned to the yellow key, and the change process is interrupted. the

Finally, the display data generation unit 62 synthesizes the control script 110 generated by the control script generation unit 80 , the display object 111 (slideshow photo), and other objects (sound files, etc.) to generate the display data 7 . the

As can be seen from the above, if the TV set 1 acquires the above-mentioned display data 7, it can prompt the user to add auditory and/or visual effects to thumbnails or slideshow photos according to the control script 110 including the above-mentioned sound determination script 289 and/or effect definition script 284a. Effect. Specifically, in S11 of FIG. 5 , when the effect definition script 284a is described in the slideshow display data, the television 1 displays the photo by the method defined in the effect definition script 284a. the

In addition, in the present embodiment, the control script 110 can specify the timing at which the effect processing starts. For example, in the above example, since an effect is added to the display/non-display of the photo, the time when the photo is switched is described in the control script 110 as the timing at which the effect processing starts. Alternatively, in the thumbnail display screen, when the cursor is positioned on a thumbnail image and the thumbnail image needs to be zoomed in, the control script 110 may also define the time when the cursor is touched as the start timing of the effect processing. the

Also, as described above, if the control script 110 is used to describe the effect processing, it is possible to specify the object to which the effect is added for each object. Therefore, the range of adding effect processing can be limited only to the range of the target object instead of the whole screen. Therefore, compared with the case of performing effect processing on the entire screen, the load of effect processing on the television 1 can be greatly reduced. the

In addition, in the data for slide show display, it is not necessary to include the audio specifying script 289 in all the data for display of each photo. For example, the control script 110 may be written such that the audio specifying script 289 is included only in the display data for displaying the first picture, and playback is continued when the subsequent pictures are displayed. the

Also, as described above, in the present embodiment, the display data generation device 2 describes in the effect definition script 284a the operation of interrupting the application of the effect (effect processing) corresponding to the event of pressing the yellow button. As a result, the user can interrupt effect processing at any timing by pressing a button. the

If the effect processing is performed during the processing of the data for slide show display, the load on the television 1 will be increased, and the response to the user's key operation will be slowed down, resulting in poor operability. This is because, usually, the CPU load of effect processing is large. the

However, according to the above configuration, when the yellow button is pressed, the effect processing is interrupted, and the television 1 immediately displays the target picture. Therefore, effect processing not desired by the user can be omitted, the load on the television 1 can be reduced, and the processing efficiency of the television 1 can be improved. the

Furthermore, the event that triggers the interrupt processing is not limited to pressing the yellow button. For example, the control script generating unit 80 may describe the script so that "when the GUI screen of the operation menu is called" is used as a trigger to suspend the effect processing. the

Also, when assigning the function of calling (displaying) the GUI screen of the operation menu to the yellow key, if "when the yellow key is pressed" is used as the condition for interrupting the effect processing (end="accessKey(y)"), the result will be The script is described in such a way that "when the GUI screen of the operation menu is called" is used as a trigger, and the effect processing is interrupted. the

It is also possible to describe the script so that even during the effect processing, as long as there is a key operation indicating to transfer to the next slide or the previous slide, the effect is interrupted and the designated slide is immediately transferred. the

Furthermore, when the user does not wish to perform effect processing that increases the load, a GUI screen configured to enable selection of whether or not to have an effect may be displayed from the above-mentioned operation menu. In this case, the script is described such that when the user selects no effect, the television 1 does not execute effect processing from the beginning. the

Alternatively, the control script 110 may be described so that the presence or absence of the effect can be switched by a simple operation of pressing a button provided on the operation unit 13 of the television 1 without calling the above-mentioned operation menu. the

FIG. 51 is a diagram showing a specific example of the control script 110 including an operation function definition script 132 that defines the operation of the television 1 in order to switch the presence or absence of an effect according to the user's key operation. the

In the example shown in FIG. 51, the control script 110 includes: an effect definition script 284b; an operation function definition script 132e that controls the execution of the effect definition script 284b; The operation function definition script 132f. the

The operation function definition script 132e is defined to execute the effect defined by the effect definition script 284b when the effect flag defined in the script indicates "1" when the processing of the display data 7 is initialized. the

Furthermore, in the operation function definition script 132f, an operation of switching the above-mentioned effect flag when the blue key (key (b)) of the operation unit 13 is pressed is defined. the

According to such a control script 110 , the television 1 can switch whether or not to have an effect when the user presses the blue button. the

In addition, in the example of FIG. 51 mentioned above, the structure which controls presence or absence of an effect by changing the attribute "visibility" of the effect definition script 284b is adopted, but the description method of the control script 110 is not limited to this. For example, the TV 1 can disable the effect according to a script describing an action of changing the value of the attribute "display" of the effect definition script 284b to "none". In this case, the television 1 can perform rendering at a higher speed than the rendering process of the entire SVG related to the visibility attribute. the

In addition, in the above description, the case where effects and sounds are applied when displaying still images such as photographs is described, but the present invention is not limited thereto, and effects and sounds may be applied to moving images when displaying moving images in thumbnail display or slide show. the

Also, in the above description, a case where one effect processing is defined for one target object has been described, but the present invention is not limited thereto. A plurality of effect definition scripts may be described in advance in the control script 110 for one object. In this way, the user can not only select whether to enable/disable the effect from the menu, but also can select a desired effect to be added to the object from the above-mentioned plurality of effects. the

For example, two kinds of animations (effects) based on the spring theme of a certain character are prepared for males and females, and are defined in advance in the control script. Then, according to the control script, the television 1 can add and display the animation selected by the user among the above two animations to the above-mentioned character. the

Also, in this embodiment, the display data generating device 2 has an effect definition script table and provides the TV 1 with the effect definition script included in the display data 7, but it is not limited to this. Even if the TV 1 has an effect definition script table, the same effect can be obtained. That is, the display data generating device 2 may be used as a script indicating which effect is added to which photo in correspondence with the photo description effect ID. the

Based on the effect ID included in the display data 7 , the television 1 can refer to its own effect definition script table, and can prompt the user to add an appropriate effect to an appropriate photo. the

As a result, a network album system capable of providing various album contents that can be better enjoyed by each user according to the user's preference can be realized. the

Modification 6 - Character display processing when the effect is valid

When the television 1 adds effects to display photos in an album in a slide show using the above-mentioned method, character display processing may be performed in addition to the processing of adding effects and drawing photos. The character display process refers to a process of superimposing and displaying text data included in the display data 7 on a photograph. the

FIG. 52 is a diagram showing an example of a slide show display screen displayed on the display unit 15 of the television 1 . As shown in FIG. 52, when the slide show display screen is displayed, in addition to displaying photos, operation information 152 indicating the operation guide of the remote controller, playback status display 153 indicating the playback status of the slide show, photo titles 154, And a comment 155 added to the photo. These characters are described as text data in the layout definition information of the display data 7 , and the display data 7 is processed by the television 1 to be displayed. In addition, text data is not limited to the above. the

The above-described character display processing is a processing that adds a relatively large load, similarly to the effect processing. Therefore, when the television 1 performs slide show display processing in which the effect is effective, both the effect processing and the character display processing must be executed every time the television 1 draws a slide show. In this case, due to the load of the character display processing, the intentionally added effect processing cannot be performed smoothly, or the response of the key operation from the remote controller (operation unit 13 ) is deteriorated, thereby impairing user convenience. the

Therefore, in the present embodiment, a method for distributing the load on the television 1 in the slide show display process when the effect is effective to smooth the operation of the television 1 will be described. the

Control script for distributing load over time

In this embodiment, when displaying a slide show, the television 1 uses a control script to control the execution time of each processing in the television 1 so that the effect processing and the character display processing are not executed simultaneously. Specifically, the following description is made in the control script: that is, when the effect is valid, the character display process is started after the effect process is completed. the

FIG. 53 is a diagram showing a specific example of the control script 110 defining the operation of the television 1 so that the character display process starts after the effect process is completed. the

In the example shown in FIG. 53 , the control script 110 includes: an operation function definition script 132g; an effect definition script 284b; and a display object determination script 121a. the

The display object specifying script 121a is a character specifying script for specifying text data to be displayed. the

In the operation function definition script 132g, a script for command execution character display processing and a script for defining its execution timing are described. Specifically, the operations of the television 1 are defined in the operation function definition script 132g so that when the effect processing of the effect definition script 284b ends, the characters of the display object specifying script 121a are displayed. the

In addition, the time when the effect processing defined by the script ends may be the time when the effect processing is executed to the end, or may be the time when it is interrupted by user operation or the like. the

When the television 1 needs to execute both the effect processing and the character display processing according to the above-mentioned control script 110, the effect processing can be executed first, and then the character display processing can be executed after completion. That is, high-load processing can be distributed temporally. Therefore, since the load is no longer concentrated for a while, it is possible to solve the problem that the added effect processing cannot be performed smoothly or the response of the key operation from the remote controller (the operation unit 13 ) is deteriorated. the

Furthermore, although effect processing and character display processing as high-load processing that should be temporally distributed have been exemplified, it is not limited thereto. The display data generation device 2 can describe in the control script 110 the execution timing of any high-load processing that is preferably not executed simultaneously with the effect processing. For example, the display data generation device 2 may describe in the control script that after the operation menu display process as the function of the television 1 described in the first embodiment is started, the execution of the effect process is interrupted. the

Display structure of data generation device

In this embodiment, the display data generating device 2 ( FIG. 46 ) generates display data 7 including effect processing in response to a request from the television 1 . the

In this case, the display data generating device 2 generates the control script 110 defining the operation (and its timing) of the television 1 so that the processing that should not be executed during the above-mentioned effect processing is executed after the above-mentioned effect processing. For high-load processing that should not be executed during the effect processing, pattern data describing a timing not to execute simultaneously with the effect processing is stored in the pattern data storage unit 91 in advance. Specifically, the pattern data selection section 61 can select from the pattern data storage section 91 pattern data including a script describing execution of character display processing after effect processing and a script describing interrupting execution once operation menu display processing starts. Script for effects processing. The control script generating unit 80 generates the control script 110 based on the pattern data. the

Therefore, it is possible to control the television 1 so that high-load processing such as character display processing and operation menu display processing and effect processing are executed in a time-shifted manner. Thereby, concentration of load on the television 1 can be avoided, allowing the user to operate the television 1 smoothly. the

Alternatively, a list in which high-load processing is associated with the start and end timing of the processing may be registered in the storage unit 90 in advance. When generating a control script including a process registered in the list, the control script generation unit 80 generates the control script based on the list and executes (interrupts) at a timing corresponding to the process. the

In addition, the display data generation device 2 can generate a control script related to effect processing based on the content of the received display data request message 6 . the

For example, as shown in FIG. 7 , when a display data request message 6 including model name and software version information is received, the related information acquiring unit 73 acquires the message. the

The information about the function corresponding to the model and the software version is prestored in the storage unit 90, therefore, the display data generation device 2 (pattern data selection unit 61/control script generation unit 80) based on the model name and software version information, The function of the television 1 can be determined. Specifically, it can be determined whether or not the television 1 has a function of outputting visual effects (effect processing) and auditory effects (sound effects, music, etc.). the

When the television 1 is displaying the photos in the web album in a slide show (thumbnail), the control script generation unit 80 generates an image for effect processing or sound output only if it is determined that it is a type capable of effect processing or sound output. control script. Alternatively, when it is determined that the television 1 is of a type capable of effect processing or audio output, the pattern data selection unit 61 selects pattern data including a scenario for performing effect processing or audio output. the

Conversely, when it is determined that the television 1 is of a type that cannot perform sound output or effect processing, since descriptions related to effect processing or sound output are unnecessary, the control script generation unit 80 generates a slide show that does not include these descriptions. (Thumbnail) Control script for displaying photos. the

Thereby, the display data generation device 2 can remove unnecessary descriptions according to the specifications of the television 1, and can always generate and provide a control script that is optimal for the requesting television 1. the

Implementation mode 6

Modification 7 - Change function of control script in TV 1

In each of the above-mentioned embodiments, a case has been described in which, in the network album system 100, the control script generating unit 80 of the display data generating device 2 located on the side of the server providing the display data generates a control script based on the above-mentioned pattern data, The television 1 operates according to the control script. the

However, the web album system 100 of the present invention is not limited to the above structure. A configuration may also be employed in which the TV 1 as a client receiving the display data 7 uses its own device to change a part of the control script provided by the display data generating device 2 and operate according to the changed control script. the

Specifically, the operation content definition script 113 defining the operation of the TV 1 is included in the control script provided by the display data generating device 2 so that the TV 1 can modify a part of the control script or replace it with other values. the

The display data execution processing unit 40 of the television 1 can modify a part of the control script provided by the display data generation device 2 or replace it with other values according to the above-mentioned operation content definition script 113, based on the information pre-stored in the device. . the

At this time, the operation content definition script 113 in the control script provided by the display data generation device 2 includes a reference script for instructing to refer to and acquire information of the TV 1 as the client, so that the information stored in the TV 1 or Make appropriate changes according to the content of this information. The display data execution processing unit 40 of the television 1 obtains the information of the specified device according to the above-mentioned reference script, and transfers the obtained information as a variable value to, for example, the layout definition script 112. As a result, the information obtained from the device Embedded in the control script, the control script to be finally executed (displayed) by the display data execution processing unit 40 is completed. the

As a result, not only the display data 7 designated from the server side but also the display data 7 changed on the client side are processed and provided to the user. Each device and the user of the device provide more personalized services. Therefore, it is possible to construct the network album system 100 capable of more flexibly responding to various needs of each user. the

Next, the operation of the television 1 will be described by taking the case where the television 1 displays the album history screen 440a shown in FIG. 44(a) based on the display data 7 as an example. The television 1 changes a part of the control script received from the display data generating device 2 according to the reference script, and displays the album history screen according to the changed control script. the

Application example 1- Display number of change history

As shown in FIG. 6 , the television 1 stores album IDs of albums that the user has browsed in the past (up to three albums from the most recent album) in the album ID storage unit 53 . When requesting the display data 7 for displaying the album history screen from the display data generator 2, the television 1 transmits the album ID stored in the album ID storage unit 53 to the display data generator 2 (display data request message 6). the

The display data generation device 2 generates the display data 7 of the album history screen according to the above display data request message 6 and provides it to the TV 1. The photo album history screen displays the last three items browsed in the TV 1 in the past related to the album. historical information. As for the display data 7 , the layout of the album history screen, the operation of the television 1 necessary for displaying the screen, and the like are defined in the control script. the

In this embodiment, if the received control script includes the operation content definition script 113 including the reference script, the TV 1 changes a part of the above control script according to the operation content definition script 113 using the data stored in the device. . Fig. 54 is a diagram showing a specific example of a control script including a reference script. The reference script 160 defines the acquisition of the value of the setting information "historical display number" and takes this value as the variable value "h_max". The television 1 acquires the information of the "number of historical displays" stored in the related information table of FIG. 8 . the

Then, in the example shown in FIG. 8 , the television 1 detects that the number of history display items is two, and changes the control script so that only the album history of the above-mentioned two items is displayed. Specifically, change the visibility attribute of the album history information to "hidden". the

Furthermore, the television 1 can also change the control script so that the album selection function assigned to the number keys for selecting an album from the album history screen is disabled. That is, since there are two displayed album histories, the control script is changed so that only the numeric keys "1" and "2" are valid. That is, the television 1 can change the control script that defines the button to be pressed and the action to be executed when the button is pressed as described in the third embodiment, according to the number of historical displays. the

FIG. 55 is a diagram showing a specific example of a control script obtained by changing a part of the control script received from the display data generating device 2 by the television 1 . The visibility attribute 161 shown in the dotted line box is provided to the television 1 in the state of "visible" before the change, but according to the setting information "historical display number" (= two), the television 1 becomes "hidden". state. the

Then, according to the changed control script, when the display data execution processing unit 40 executes the display data 7 of the album history screen, an album history screen in which only two pieces of album history information are displayed is output based on the above-mentioned setting information ( FIG. 56 ). . Next, in the state where the album history screen is displayed as shown in FIG. 56, a part of the control script is changed so that the number keys of "3" are invalid, so that the third segment cannot be selected. the

As described above, the TV 1 can change a part of the control script when displaying the album history screen based on the setting information stored in the TV 1, and change the state when the display data generation device 2 provides the number of displays. the

Application example 2: Always display the album specified by the user

In this embodiment, the album ID storage unit 53 of the television 1 may store, in addition to the album IDs of the most recently browsed albums, the album IDs of the albums whose album history screen is always displayed regardless of the browsing time. Therefore, set the always-on display setting of this album to be valid. This setting can also be stored in the related information table shown in FIG. 8 . In this way, regardless of the period of past browsing, the user can select another album that he always wants to display instead of the third album, and always display it on the album history screen. the

The television 1 first receives display data to be displayed sequentially from the most recently browsed album. As shown in FIG. 57 , the display data 7 includes a reference script 162 stored in the television 1 that instructs to refer to an album ID that is always displayed. The television 1 obtains the album ID that is always displayed according to the reference script 162, and changes a part of the control script of the current album history screen when the always display setting is enabled. Specifically, for example, the current historical information of the third album is replaced with the acquired historical information of the always-displayed album. the

FIG. 58 is a diagram showing a specific example of a control script before replacement of the TV 1 and a control script after replacement. the

After television 1 acquires the album ID displayed all the time according to the reference script 162 of Figure 57, according to the follow-up control script, the album history information 163a of the third piece is replaced with the album history information 163b of the album displayed all the time. the

Since the display data execution processing unit 40 executes the display process of the album history screen according to the replaced control script, it outputs the album history screen in which the history information of the album that is set to be valid is always displayed in the third stage instead of the original display content. . the

As described above, the TV 1 can change (replace) a part of the control script based on the information of the always-display setting stored in the device, so that the album that is set to be valid is always displayed on the album history screen, thereby changing the display. Content. the

In addition, there is no particular limitation on replacing several photo albums that are always displayed. What is necessary is just to designate in advance in the control script before a change (replacement) sent from the data generating apparatus 2 for display. the

In the above description, the structure of changing (replacing) a part of the control script of the television 1 is described by taking the album history screen as an example, but the present invention is not limited thereto. The structure in which the television 1 changes (replaces) a part of the control script may be combined with the structures in the above-described embodiments. the

In each embodiment, the television 1 changes a part of the control script acquired from the display data generation device 2 based on various information that can be acquired from the television 1 . the

For example, in Embodiment 1, the television 1 receives display data 7 for displaying an operation menu based on display contents. According to the present embodiment, the TV 1 can change a part of the control script contained therein based on various information of the device acquired by the TV 1 (for example, the related information table in FIG. 8 ). For example, if there is an operation menu option that defines an action that does not meet the specifications of this device, you can delete that option. Thereby, the television 1 can display operation menu items suitable for the specification information of the television 1 . the

In addition, examples of the information stored in the device acquired by the television 1 according to the reference script are not limited to the information listed in the above-mentioned application examples. The television 1 can obtain all information stored in the device, and pass it to the layout definition script 112 as a variable value. For example, the acquired information includes not only text data such as album IDs and album titles, but also index images of each album, etc. When displaying the album history screen, the control script provided by the data generation device 2 may be displayed. Part of is replaced with the title and index image acquired from this device, and a new album history screen is displayed. the

It is also possible to change the control script of the effect or sound output together with the album (photograph) using the information stored in the television 1 . the

Application example 3: Always output certain visual and auditory effects

In the present embodiment, the television 1 on the client side adopts a configuration in which the album information table shown in FIG. 20 is stored in the device. That is, the TV 1 can determine the effect and sound related to the album or photo to be displayed according to the album information table stored in the device. Here, the album information table stored in the television 1 does not need to be consistent with the information stored in the network album DB 8 referred to when the display data generating device 2 generates the control script. For example, in this device, effects or sounds that the user particularly likes are stored in association with a certain album (or photo). Therefore, the television 1 can appropriately select the user's favorite sound and effect for the effect to be output together with the album (photograph). the

The television 1 first receives the requested display data 7 from the display data generating device 2 . Here, as an example of the display data 7, it is the display data for displaying a slide show display screen, and in the control script included in the display data 7, a photo and corresponding output sound and effect (first) are defined. sounds and effects). Furthermore, the operation content definition script 113 contained in the control script includes a reference script, and defines an operation of replacing the sound and effect to be output with the sound and effect managed in the device. the

The display data execution processing unit 40 obtains the sound and effect (second sound and effect) related to the photo to be displayed from the album information table stored in the device according to the above-mentioned reference script, and compares it with the above-mentioned first sound and effect. to replace the description. the

Thus, the display data execution processing unit 40 can output the second sound and effect registered in the TV 1 as the user's preference, instead of outputting the second sound and effect specified by the display data generation device 2, together with the above-mentioned photo according to the replaced control script. first sounds and effects. the

Alternatively, the television 1 may be configured as follows. That is, the television 1 is configured to store the effect definition script table shown in FIG. 47 in its own device. the

In the present embodiment, in the control script provided by the display data generating device 2, only the "effect ID" corresponding to the photo is described, and a reference script is described at the definition position of the detailed operation related to the effect. the

According to the above-mentioned reference script and the effect ID corresponding to the above-mentioned photo, the TV set 1 obtains the required information from the effect definition script table saved by the device, and completes the definition of detailed actions related to the above-mentioned effect. the

In this way, the television 1 can be configured to always output the effects stored in the device together with the photos. the

In addition, regardless of the effect ID defined in the control script (or whether it is defined or not), it can be replaced with a description of the action to determine the effect to output the effect, or multiple A randomly selected effect among effects is replaced. the

Alternatively, the following structure may also be adopted: that is, the television 1 does not store the above-mentioned album information table and the above-mentioned effect definition script table, but only pre-stores (for example, user's favorite) sounds and effects. the

In this embodiment, even if the control script provided by the display data generation device 2 includes a description of certain sounds and effects, the TV 1 can replace a part of the control script according to the reference script, so that the TV output is always output. Sounds and effects pre-stored in Unit 1. Or, when a plurality of sounds and effects are stored in the television set 1, the television set 1 can also replace and output the sound and effects randomly selected from the stored plurality of sounds and effects when the photo is reproduced. the

Accordingly, the television 1 can be configured such that the sound and effect registered in the television 1 are always output regardless of the sound and effect output by the specified display data generating device 2 . Therefore, it is possible to provide a service that suits the user's preference according to the setting content in each television 1 on the client side. the

The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. the

In addition, in the above description, the case where the television 1 which is the image display device of the present invention displays an image according to the display data generated by the display data generating device 2 which is the image data providing device of the present invention is described. However, the image display device and the image data providing device of the present invention are not limited thereto. the

The control script execution unit 41 controls the basic function execution unit 42 to execute the second function according to the control script. the

Therefore, using the control script, not only the function of displaying the object but also various second functions can be realized in the image display device. the

Furthermore, in addition to defining the above-mentioned first and second functions, a re-rendering area is also defined in the above-mentioned control script. The so-called re-rendering area refers to the area of the display screen that should be re-rendered when the image display device needs to change the display content due to the execution of the first or second function. Among the above-mentioned first and second functions, the functions accompanied by the change of the displayed content are referred to as functions accompanying the change. the

When the above-mentioned control script execution unit 41 executes the above-mentioned modified supplementary functions, it controls the above-mentioned basic function execution unit 42 according to the definition of the re-rendering area described in the above-mentioned control script, determines the re-rendering area, and executes the re-rendering of the re-rendering area. . the

Thus, by using the control script, when the first or second function is executed on the image display device, the display content in the re-rendering area defined by the control script can be changed. the

The control script is a script that can be included in the display data every time according to the content to be displayed, and can be provided to the image display device. Therefore, according to what kind of object is displayed, what kind of function is executed, etc., the re-rendering area can be arbitrarily and dynamically defined, and the image display device can be re-rendered. the

As can be seen from the above, even after the image display device is launched, the above-mentioned second function to be executed by the image display device can be flexibly added or changed, and the basic function program stored in the basic function program storage unit can be easily implemented without updating the basic function program. Functional change of the image display device. Furthermore, the re-rendering area can be dynamically defined according to the situation, and the image display device can be re-rendered easily. the

In addition, even when the basic function program storage unit is realized by a nonvolatile storage device such as ROM and the stored basic function program cannot be easily rewritten, the functions of the image display device can be easily changed as described above. Therefore, when the image display device of the present invention is applied to a combination device, the effect is particularly large. the

Also, since functions can be changed easily in this way, it is possible to save the trouble of considering all requirements before selling and installing a large number of functions in advance to cover these requirements for pre-installed functions. As a result, the burden of image display device development can be reduced. the

Then, the control script defining the first function and the second function described above is included in the display data together with the image displayed by the image display device and supplied to the image display device. Therefore, it is possible to manage the displayed image in association with the second function, and it is easy to perform both on the side that generates and transmits the display data and on the side (image display device) that receives and processes the display data. manage. the

Furthermore, since the control script is generated for each display data (and the image contained therein), the image display device can efficiently acquire only the display data (object) processed by itself based on the display data (object). Secondary functions required, or in the case of these functions incidental to changes, obtain control scripts that define appropriate rerendering regions. the

From the above, it is possible to efficiently develop an image display device and to easily change the functions of an already-marketed image display device. the

Furthermore, it is preferable that the above-mentioned control script is defined so that the above-mentioned redrawing area completely includes the display area of the above-mentioned object or does not include the display area of the above-mentioned object at all. the

According to the above configuration, the image display device determines the redrawing region so as to completely include or not include the target object when specifying the redrawing region necessary for executing the changed incidental function according to the above-mentioned control script. That is, the re-rendering area does not include only a part of the object. the

Therefore, using the control script, the image display device can be controlled so as to execute the re-rendering process only on objects completely included in the re-rendering area. the

As described above, the control script can arbitrarily designate the redrawing area where the image display device performs redrawing, and therefore, it is particularly effective in the following cases. the

For example, assume that the above-mentioned display screen contains overlapping objects. the

When the change incidental function is executed while an object (hereinafter referred to as a change target object) is displayed, an area (for example, a circumscribing rectangle) completely including the change target object is determined as a redrawing area. However, as long as some other overlapping objects are included in the re-rendering area, correct re-rendering cannot be performed only by re-rendering the object to be changed included in the re-rendering area. It is necessary to re-render all objects contained in the above-mentioned re-rendering area. the

Here, when another object is partly included in the redrawing area, it is necessary to perform a process of specifying only a part (clipping area) of the object included in the redrawing area in order to perform redrawing. In this way, the processing of finding the clipping area is called clipping processing. The more complicated the shape of the object, the higher the processing load on the image display device. Therefore, it is desirable to determine the redrawing area so as to completely include or not include the target object. Also, in order to reduce the load of the re-rendering process, it is also desirable to limit the re-rendering area to the necessary minimum. the

Here, if the above-mentioned control script is used, according to the content of the display data, it is possible to designate the redrawing area so that objects (particularly objects with complex shapes that increase the load of clipping processing) are not partially included, and limit it to the minimum required area. the

Therefore, when re-rendering is performed according to such a control script, the image display device avoids the clipping process and only determines the minimum necessary area as the re-rendering area, so that the re-rendering process can be performed efficiently. the

Alternatively, the above-mentioned re-rendering area may also be defined in the above-mentioned control script in such a way that it is the entire display screen of the device. the

According to the above configuration, when the image display device executes the additional function of changing, the entire display area is determined as the re-rendering area according to the above-mentioned control script, and the re-rendering is executed. the

Therefore, desired redrawing can be performed on the entire display screen, and the display screen can be switched accurately. the

In addition, the method of specifying the re-rendering area in the above-mentioned control script is an example, and is not limited thereto. For example, in an image display device with insufficient work storage area, in order to switch the display screen smoothly, it is also possible to designate a re-rendering area so that a predetermined display device is always re-rendered or designate an object so that a certain target object is always re-rendered. re-rendering, so that the image display device determines the re-rendering area. the

In order to achieve the above object, the image data providing device of the present invention generates display data for the image display device to display the object, and the image data providing device is characterized in that it includes: generating a control device that defines at least the first function of displaying the above-mentioned object and a display data generating part 62 for generating display data, the display data including the above-mentioned object and the above-mentioned control script generated by the control script generating part 80, the control script generating part 80 generating control A script, the control script also defines the action of the image display device when the first function is used to display the object as the second function, and also defines a re-rendering area, and the re-rendering area refers to when the first function or The second function is an area of the display screen to be redrawn by the image display device when the additional function is changed accompanying a change of the display screen in the image display device. the

According to the above configuration, the control script generation unit 80 generates a control script that defines the first function and the second function, and defines an area where re-rendering is required when each function is changed as a re-rendering area. the

Thus, even after the image display device is launched, the above-mentioned second function to be executed by the image display device can be flexibly added or changed, and the image display can be easily performed without updating the basic function program stored in the basic function program storage unit. Functional changes of the display device. Furthermore, the re-rendering area can be dynamically defined according to the situation, and the image display device can be re-rendered easily. the

Preferably, the control script generation unit 80 generates a control script defined such that the redrawing area completely includes the display area of the object or does not include the display area of the object at all. the

In this way, the image display device can be controlled so that high-load clipping processing can be avoided, and the minimum required area can be specified as the re-rendering area, so that efficient re-rendering processing can be performed. the

Alternatively, the control script generation unit 80 may generate a control script that defines the redrawing area so as to be the entire display screen of the image display device. the

Therefore, in the image display device, desired redrawing can be performed on the entire display screen, and the display screen can be switched accurately. the

Supplement 4

In order to achieve the above object, the image display device of the present invention processes display data acquired from the outside to display an image, and the image display device is characterized in that the display data includes an image and a control script, and the control script defines the The first function of the image and the operation of the device when the image is displayed using the first function, that is, the second function, the image display device includes: executing the basic function program stored in the basic function program storage unit called from the above control script and the control script execution unit 41 that controls the above-mentioned basic function execution unit 42 according to the above-mentioned control script, and executes the above-mentioned first function and the above-mentioned second function defined in the above-mentioned control script. In the above-mentioned control script, at least As the second function, the control script execution unit 41 displays the image according to the control script and executes the visual effect output function on the image. the

According to the above configuration, the image display device acquires display data including an image and a control script defining at least a first function for displaying the image, processes the display data, and displays the image. Specifically, the control script execution unit 41 controls and executes the basic function execution unit 42 that executes the basic function program called from the control script included in the display data according to the control script, and executes the function (first function) defined in the control script. , displaying the image. That is, one or more basic functions described above are combined based on the control script to realize one function (the first function described above, etc.) of the image display device. the

Furthermore, in the control script, in addition to defining the first function of displaying an image, an operation of the image display device when the object is displayed by the first function is defined as a second function. The above-mentioned second function is also a function of the image display device realized by combining the above-mentioned basic functions. the

The control script execution unit 41 controls the basic function execution unit 42 to execute the second function according to the control script. the

Therefore, by using the control script, not only the function of displaying images but also various second functions can be realized in the image display device. the

Specifically, a visual effect output function for displaying an image displayed by the first function accompanying an action is defined in the control script as the second function. the

Therefore, the control script execution unit 41 displays the image using the first function, and executes the visual effect output function on the image. That is, the above-mentioned image is displayed with motion. the

Thus, by using the control script, the above-mentioned visual effect output function can be included in the display data every time according to the content to be displayed, and can be provided to the image display device. Thus, depending on what kind of image is displayed, the image display device can be made to perform a visual effect output function. Utilizing the second function, that is, the visual effect output function, very interesting content can be provided to the user in combination with the displayed content. the

As can be seen from the above, even after the image display device is launched, the above-mentioned second function to be executed by the image display device can be flexibly added or changed, and the basic function program stored in the basic function program storage unit can be easily implemented without updating the basic function program. Functional change of the image display device. the

In addition, even when the basic function program storage unit is realized by a nonvolatile storage device such as ROM and the stored basic function program cannot be easily rewritten, the functions of the image display device can be easily changed as described above. Therefore, when the image display device of the present invention is applied to a combination device, the effect is particularly large. the

Also, since functions can be changed easily in this way, it is possible to save the trouble of considering all requirements before selling and installing a large number of functions in advance to cover these requirements for pre-installed functions. As a result, the burden of image display device development can be reduced. the

Furthermore, the control script defining the above-mentioned first function and second function is included in the display data together with the image displayed by the image display device and supplied to the image display device. Therefore, the displayed image can be managed in association with the second function, and it is easy to perform both on the side that generates and transmits the display data and on the side (image display device) that receives and processes the display data. manage. the

Moreover, since the control script is generated for each display data (and the image contained therein), the image display device can efficiently acquire only the display data (image) required for its own processing based on the display data (image). The second function (visual effect output function). the

From the above, it is possible to efficiently develop an image display device and to easily change the functions of an already-marketed image display device. the

Preferably, in the above-mentioned control script, an object display function of superimposing and displaying an object on the image displayed by the above-mentioned first function is defined as the above-mentioned second function, and the timing of each of the above-mentioned second functions is defined such that The device does not execute the object display function during the execution of the visual effect output function, and the control script execution unit 41 executes each of the second functions according to the timing defined by the control script. the

In the above-mentioned control script, an object display function may also be defined as the above-mentioned second function. The above-mentioned panel display function is a function of superimposing and displaying an object on the image displayed by the above-mentioned first function. The so-called object refers to an object displayed on an image display device, and refers to all display objects such as images, moving images, graphics, texts, photographs, and illustrations. the

In addition, the control script execution unit 41 executes a visual effect output function and an object display function on the image displayed by the first function according to the control script. Here, since the timing of each function is defined in the above-mentioned control script, the above-mentioned object display function is not executed during the execution of the above-mentioned visual effect output function. Each function is performed like an object display function. the

If the above-mentioned visual effect output function and the above-mentioned object display function are executed at the same time, the image display device has to superimpose and display the object on the image displayed along with the motion. In this way, the process of drawing other characters or graphics while superimposing on the animation-added image becomes a high-load process. Therefore, there is a problem that the load is concentrated on the image display device, and each function cannot be smoothly executed. the

According to the above configuration, since the control script execution unit 41 executes each function according to the control script so as not to execute the visual effect output function and the object display function at the same time, concentration of load on the image display device can be avoided. the

Specific examples of the object display function include a character display function (a function to display comments or titles of photos (images), etc.) and an operation menu display function (a function to display a list of operations that a user can perform on photos). the

In the above-mentioned control script, the start of the above-mentioned object display function may also be defined as the end condition of the above-mentioned visual effect output function, and when the above-mentioned control script execution unit 41 starts to execute the above-mentioned object display function, it will end the execution of the above-mentioned object display function according to the above-mentioned end condition. Visual effect output function. the

According to the above structure, the control script executing unit 41 executes the above-mentioned visual effect output function, once an instruction to start the above-mentioned object display function is inserted (for example, an instruction to execute the above-mentioned object display function through user operation, etc.), End condition, end the visual effect output function being executed. the

Therefore, since the object display function can be executed after the visual effect output function is terminated (interrupted), it is possible to avoid the situation where the load is concentrated on the image display device. the

Alternatively, in the above-mentioned control script, the end of the above-mentioned visual effect output function may also be defined as the start condition of the above-mentioned object display function. Execute the object display function described above. the

According to the above structure, when the above-mentioned control script execution unit 41 executes the above-mentioned visual effect output function, once an instruction or command to start the above-mentioned object display function is inserted to simultaneously (or almost simultaneously) execute the visual effect output function and the object display function, According to the above starting conditions, the visual effect output function is executed first, and then the above object display function is started to be executed. the

Therefore, since the object display function can be executed after the execution of the visual effect output function is completed, concentration of load on the image display device can be avoided. the

In the above-mentioned control script, an auditory effect output function may also be defined as the above-mentioned second function, and the auditory effect output function outputs sound data related to the image displayed by the above-mentioned first function, and the above-mentioned control script execution unit 41 follows the above-mentioned control script, At least one of the above-mentioned visual effect output function and the above-mentioned auditory effect output function related to the image displayed by the above-mentioned first function is executed. the

Therefore, since the image display device can use the first function and the visual effect output function to display an image and output sound data related to the image, it can provide richer content to the user. the

In order to achieve the above object, the image data providing device of the present invention generates display data for displaying an image by the image display device, and the image data providing device is characterized in that the above-mentioned display data includes an image and a control script, and the control script defines how to display the image. The first function of the image and the second function of the operation of the image display device when the image is displayed by the first function, the image data providing device includes: displaying the display data according to a request sent from the image display device The display object ID acquisition part 71 that acquires the identification information of the requested image with the data request message; the control script generation part 80 that generates the control script, and the control script defines the display determined by the identification information acquired by the above-mentioned display object ID acquisition part 71. The first function of the request image, and at least define the visual effect output function of displaying the request image accompanying the action as the second function; The above-mentioned control script generated by the control script generating unit 80 . the

According to the above configuration, the image data providing device generates display data for displaying a requested image, that is, a requested image, based on a display data request message generated by the image display device for requesting the display data. The display data includes a request image and a control script defining a first function for displaying the request image and the aforementioned second function related to the request image. Here, at least a visual effect output function for displaying the requested image by adding an action to the requested image is defined as the second function. the

Specifically, the display object ID acquisition unit 71 acquires identification information of a requested image from the display data request message. Based on this identification information, the requested image to be included in the display data is specified. the

Then, the control script generating unit 80 generates a control script defining a first function for displaying the requested image. Also, add the following definitions to this control script. That is, it is a definition of an operation as the second function of the image display device when the requested image is displayed by the first function. The control script generating unit 80 generates a control script defining the second function (at least the visual effect output function) based on the content of the display data request message. the

Finally, the display data generation unit 62 generates display data including the request image and the control script generated by the control script generation unit 80 . the

Thus, based on the display data (image) requested by the image display device, a control script defining the first and second functions can be generated, and the display data including such a control script can be provided as a request to the image display device. response. the

The control script generating unit 80 generates the control script to define, as a second function, an operation of the image display device when displaying the requested image by the first function in addition to the first function of the image display device to display the requested image. The second function described above is also a function of the image display device realized by combining basic functions of the image display device. the

Therefore, by generating a control script based on the content of the display data and providing it to the image display device, not only the function of displaying the requested image but also various second functions can be provided to the image display device. Moreover, as the second function, since at least the above-mentioned visual effect output function is defined, the above-mentioned image display device can add actions to the image displayed by the first function and display it. Using this visual effect output function, it is possible to combine the displayed content to the user. Provide more interesting content. the

As described above, even after the image display device is launched, the second function executed by the image display device can be flexibly added or changed without updating the basic function program stored in the basic function program storage unit of the image display device. Functional changes of the image display device can be easily performed. the

In addition, even if the above-mentioned basic function program storage unit of the image display device is realized by a nonvolatile storage device such as ROM, and it is impossible to easily rewrite the stored basic function program, the image display device can be easily changed as described above. function. Therefore, when the control script generated by the control script generation unit 80 is provided to a combined device having the basic function execution unit 42 of the image display device, the effect is particularly large. the

Also, since the functions of the image display device can be easily changed in this way, it is possible to save the trouble of considering all needs before selling the functions preinstalled in the image display device and installing a large number of functions in advance to cover these needs. As a result, the burden of image display device development can be reduced. the

Then, the control script defining the first function and the second function described above is included in the display data together with the image displayed by the image display device and supplied to the image display device. Therefore, the displayed image can be managed in association with the second function, regardless of whether it is on the side that generates and transmits display data (image data providing device) or on the side that receives and processes display data (image display device). device), are easy to manage. the

In addition, since the control script generating unit 80 generates a control script for each display data (and image contained therein), the image display device can efficiently process the image display device according to the display data (image). A second function necessary for displaying data (image) is provided to the image display device. the

From the above, it is possible to efficiently develop an image display device and to easily change the functions of an already-marketed image display device. the

The visual effect applicable to the image provided to the image display device may be stored in the effect information storage unit in association with the image, and the control script generation unit 80 determines from the effect information storage unit that the image is associated with the requested image. a visual effect, and a control script defining a visual effect output function for outputting the visual effect is generated. the

According to the above configuration, the control script generating unit 80 specifies the visual effect applicable to the request image requested by the display data request message from the effect information storage unit, and defines in the control script the visual effect for executing the above visual effect on the request image. Effect output function. the

Thus, a control script can be generated and provided so that the image display device can execute a visual effect suitable for an image requested by the image display device. the

Preferably, the display data request message includes specification information indicating basic functions of the image display device, and the control script generator 80 determines whether the control script includes the visual effect output function based on the specification information. definition. the

According to the above configuration, the display data request message transmitted from the image display device includes specification information indicating which basic functions the image display device has. Based on the specification information, the control script generation unit 80 determines whether or not the image display device has a basic function for executing a visual effect output function. Then, based on the determination, it is determined whether the visual effect output function is included in the control script provided to the image display device. the

Therefore, it is possible to provide a more suitable control scenario based on the basic functions of the image display device described above. the

Specifically, when the control script generation unit 80 determines that the image display device is a model that can execute the visual effect output function, it may determine that the visual effect output function is included in the control script provided to the image display device. definition. On the other hand, when it is determined that the image display device is a model that cannot execute the visual effect output function, it may be determined that the definition of the visual effect output function is not included. the

For an image display device that does not originally have a basic function for executing the second function, it is useless even if the second function is defined. Therefore, in this case, by not including the definition of the second function in the control script, the data volume of the control script can be reduced, and the load of the processing of sending and receiving information, the analysis processing of the control script, and the like can be reduced. the

The control script generation unit 80 may generate a control script that further defines, as a second function, an object display function for superimposing and displaying an object on an image displayed by the first function, and defines the timing of each of the second functions. so that the above-mentioned image display device does not execute the above-mentioned object display function during the process of executing the above-mentioned visual effect output function. the

According to the above configuration, the control script generation unit 80 generates a control script that defines an object display function that superimposes and displays an object on an image displayed by the first function as the second function, and further defines the functions of each of the above functions. Timing, so that the object display function and the above-mentioned visual effect output function are not executed at the same time. the

Therefore, in the image display device, the object display function and the above-mentioned visual effect output function may not be executed simultaneously. the

If the above-mentioned visual effect output function and the above-mentioned object display function are executed at the same time, the image display device has to superimpose and display the object on the image displayed along with the motion. In this way, the process of drawing other characters or graphics while superimposing on the animation-added image becomes a high-load process. Therefore, there is a problem that the load is concentrated on the image display device, and each function cannot be smoothly executed. the

According to the above control script, since the image display device does not execute the visual effect output function and the object display function at the same time, it is possible to avoid the situation where the load is concentrated on the image display device. the

In addition, the specific example of the timing of each said 2nd function is as follows. the

In the above image data providing device, the control script generation unit may generate a control script such that the control script defines start of the object display function as an end condition of the visual effect output function. the

Alternatively, the control script generation unit may also generate the control script such that the control script defines the end of the visual effect output function as a start condition of the object display function. the

In order to achieve the above object, the image display system of the present invention is characterized in that it includes: the above-mentioned image display device; The above-mentioned control script included in the data executes the visual effect output function related to the above-mentioned requested image. the

In order to achieve the above object, the method for controlling an image display system of the present invention is a method for controlling an image display system including an image data providing device and an image display device that processes display data generated by the image data providing device to display an image. The present invention is characterized by comprising: a request step in which the image display device requests display data from the image data providing device, the display data includes an image and a control script, and the control script defines a first function for displaying the image and uses the second function to display the image.
