2. Description of the Related Art In recent years, a large number of television receivers that receive character information multiplexed and transmitted on television broadcast radio waves and display the information on a television screen have been circulating. These television receivers receive broadcast radio waves including video information of a television broadcast and text information of a teletext, and select a video information program or a text information program with a remote controller or the like, thereby obtaining the video information or the video information of the selected program. The character information is displayed on the screen of the television receiver. After downloading and storing the character information received by the television receiver in a batch process in an information terminal device or the like, carry the information terminal device to another location and display and confirm the stored character information. A system for processing is described in, for example, JP-A-10-224747.

As described above, in a conventional apparatus capable of displaying video information or text information on a screen of a television receiver by selection with a remote controller or the like, for example, when video information is displayed, it is attempted to display text information. To do this, it is necessary to interrupt the currently displayed video information and then switch to the text information screen for display.

Recently, there is a television receiver which can display a plurality of screens simultaneously on one display device by providing a plurality of receiving devices. When you try to display, switch the screen of the display device to multiple small screens,
A program such as a text broadcast is displayed on this small screen.

Further, a device has been developed in which a communication line such as a telephone line is connected to a television receiver, and bidirectional communication with, for example, an Internet server device or a specific program of a broadcasting station can be performed through the communication line. However, input of information to be transmitted in such two-way communication is only input of simple response information using the cursor buttons of the conventional remote control, or a soft keyboard is displayed on the screen of the television receiver Then, information generated by selecting a display character on the soft keyboard with a cursor of a remote controller is input.

[0006]

As described above, when trying to receive text information with a conventional television receiver, the currently viewed television program is interrupted and the screen is switched to a text broadcast screen. , There is a problem that it is annoying to other viewers who are currently watching a television program or the like.

In a television receiver capable of simultaneously displaying a plurality of screens, a character broadcast can be viewed on another screen simultaneously with the currently viewed television program. The screen becomes smaller, especially at normal viewing distances, which makes it difficult to see the text of the teletext, and there is a problem that the text cannot be read unless approaching the TV receiver. There is a problem that it is annoying to those who are watching.

[0008] Further, in the case of performing bidirectional communication with, for example, an Internet server device or a specific program of a broadcasting station through a communication line connected to a television receiver, when inputting and transmitting information, Conventionally, it is only necessary to input simple response information using the cursor button of the remote control, or to display a soft keyboard on the screen of the TV receiver and select the characters displayed on this soft keyboard with the cursor of the remote control However, there is a problem in that it is difficult to input information and characters on the screen are difficult to see, making it difficult to use.

As a means for inputting characters, a method of connecting a dedicated keyboard or the like constituted by hardware to a television receiver has been conventionally proposed. However, such a keyboard is not required for ordinary television viewing. There is a problem that it is bothersome and expensive.

In Japanese Patent Application Laid-Open No. 10-224747, after character information received by a television receiver is downloaded and stored in an information terminal device in a batch process, the information terminal device is carried to another place and stored. A system for confirming and processing character information is disclosed, but it is difficult to confirm accumulated character information easily and in real time because such information terminal devices process character information in a batch process. There is a problem that is.

[0011] The present invention has been made in view of the above,
It is an object of the present invention to provide an information receiver and an information terminal that can easily view a text broadcast or the like and can easily input information without changing a display screen during viewing.

[0012]

In order to achieve the above object, according to the present invention, an information receiver analyzes information received from an information terminal by an information receiving means, and in accordance with a result of the analysis, a character information receiving means. The information transmitting means is controlled to transmit the received character information to the information terminal for one screen, and the information terminal requests the information receiver to transmit the character information via the transmitting means. For example, the information receiver and the information terminal are respectively controlled by a television receiver and its remote controller in order to receive the character information for one screen transmitted from the information receiver through the receiving means and to control the information to be displayed on the display means. When applied to a TV receiver, the character information can be viewed on a screen that is easy and easy to read with the remote control of the information terminal without interrupting and switching the other display screens being displayed on the TV receiver. It can be.

The character information control unit 8 can transmit the input response information from the character information communication unit 19 to an external device such as a broadcasting station or an Internet server device via a communication line 25 such as a telephone line.

Next, the operation of this embodiment will be described in more detail with reference to the flowcharts shown in FIGS. 3 to 12 and FIG.

First, a process for displaying character information on the remote controller 30 in accordance with an instruction from the remote controller 30 will be described with reference to FIG. The display of the character information can be displayed on the display device 15 of the remote controller 30 without changing the image currently displayed on the receiver 21.

That is, in the input means 16 of the remote controller 30, an instruction to "display the character information on the remote controller" is input together with the channel designation information of the teletext. This instruction is input, for example, in the input character portion 1 of the input field 16a.
"Display character information on the remote control" by touching the Roman character display or Kana display touch button display of 6c
Instruction information, and then the control information section 16
b) can be performed by touching “confirm”, or by switching the TV / text broadcast selection button 41 to the text broadcast side and switching the receiver / remote control display switching button 39 to the remote control side. You can also. Further, the channel designation information of the teletext can be performed by the channel button 31 of the input unit 16.

Thus, the display device 15 of the remote controller
The instruction "display text information on the remote control" input from the remote controller 30 together with the text broadcast channel designation information is controlled by the control device 17 of the remote control 30.
Is transmitted to the receiver 21. In the receiver 21, the instruction and the channel designation information are received by the input control unit 10 via the remote control receiving unit 11. The input control unit 10 supplies the received instruction to the character information control unit 8 and supplies the channel designation information to the television control unit 4.

Since the character information control section 8 always checks whether or not there is a display instruction of character information from the remote controller 30 as shown in step S11 of FIG. 3, the character information control section 8 receives the instruction from the remote controller 30 as described above. Upon receipt, the content is analyzed, and if it is determined that the character information is to be displayed on the remote controller 30, the character information data for one screen is read from the storage device 9 (step S13).

The storage device 9 stores the channel selection unit 1 and the signal processing unit 2 in the storage device 9 based on the character broadcast channel designation information supplied from the input control unit 10 to the television control unit 4 as described above. The character information corresponding to the designated text broadcast channel is selected, and the selected character information is stored under the control of the character information control unit 8 via the character information signal processing unit 6. is there.

As described above, the character information data for one screen read from the storage device 9 under the control of the character information control unit 8 is generated on the character information screen by the display control unit 7 (step S15). It is checked whether or not the display destination of the character information is the remote controller 30 (step S1).
7). In this description, as described above, the remote controller 3
Since the display destination is specified by the receiver / remote control display switching button 39 of 0, the character information screen data for one screen is transmitted from the display control unit 7 to the remote control transmitting unit 12 via the character information control unit 8. Is transferred (step S2
1). Then, it is transmitted from the remote control transmission unit 12 to the remote control 30.

The remote controller 30 receives the character information data for one screen transmitted from the receiver 21 by the signal receiving unit 14, temporarily stores the character information data in the storage device 18 under the control of the control device 17, and then displays the data on the display device 15. It is displayed on the screen 15a. In this case, since the character information is displayed on the display device 15 of the remote controller, the character information is not affected on the screen of the program currently being viewed by the receiver 21 at all.
That is, the broadcast that is currently being viewed by the receiver 21 is not interrupted, and the broadcast is performed smoothly. Further, since the transfer of character information data is fixed to one screen, there is no need to perform complicated processing such as overflow detection.

When it is determined in step S17 that the display destination is not the remote controller but the receiver 21, specifically, the display destination is changed to the receiver side by the receiver / remote controller display switching button 39 of the remote controller. If it is specified, the process proceeds to step S19, where the character information data for one screen is transferred from the display control unit 7 to the display switching / combining unit 3, and is supplied from the display switching / combining unit 3 to the display device 5, This is displayed as switching from the program currently being received or combining a plurality of screens.

As described above, the text information of the text broadcast received by the receiver 21 is transmitted from the receiver 21 to the remote controller 30 via a wireless line using infrared rays, for example, and displayed on the display device 15 of the remote controller 30. If the wireless line between the receiver 21 and the remote controller 30, for example, the infrared ray is temporarily interrupted by some obstacle such as a person during the continuous execution of the process of The character information is not transmitted from the receiver 21 to the remote controller 30, but is skipped. However, in order to prevent such a state, for example, the remote controller 30 receives the character information every time one screen is received. A response signal is returned to the
When the receiver 21 confirms the response signal, the receiver 21 transmits the character information for the next one screen. When the receiver 21 cannot receive the response signal, the character information transmitted immediately before has some trouble. The above-described problem can be solved by performing processing such as transmitting the same character information again until it is determined that the object is interrupted and the response signal is received.

FIG. 4 is a flowchart specifically showing the processing of the control device 17 of the remote controller 30 when the remote controller 30 inputs an instruction to display character information on the remote controller in the processing of FIG. As shown in FIG. 4, the control device 17 of the remote controller 30
6 to check whether there is an input (step S2).
5, S27), when there is an input from the input means 16, a control signal including the input information is transmitted to the receiver main body 21 via the signal transmission unit 13 (step S29). The control signal transmitted to the receiver 21 includes a command to "display character information on a remote controller" and a channel number of a text broadcast as described above.

FIG. 5 is a flowchart specifically showing the processing of the controller 17 of the remote controller for receiving the character information transmitted from the receiver 21 in the processing of FIG. In FIG. 5, the control device 17 of the remote controller constantly monitors the reception status of the signal receiving unit 14 and
It is checked whether or not there is a display data signal from the receiver 21 (step S31). When it is detected that there is a display data signal, the information received by the signal receiving unit 14, ie, the character information in this example, Are once stored in the storage device 18 and then displayed on the display device 15 (step S33).

Next, referring to the flowchart shown in FIG. 6, when there are a plurality of remote controllers 30 in the configuration of FIG. 1, the receiver 21 receives a character information display instruction from an arbitrary one of the plurality of remote controllers 30. The process performed by the character information control unit 8 of the receiver 21 when displaying the character information received by the remote control 30 on the display device 15 will be described.

In the embodiment shown in FIG.
When there are a plurality of 0's, it is necessary to identify each of the plurality of remote controllers 30. For this identification, an ID, identification information and the like are assigned to each remote controller 30.

Note that the identification information is not limited to normal ID information, and various methods are possible. For example, different frequencies are assigned to the respective remote controllers 30, and the receiver 21 and the remote controller 21 are used by using these frequencies. It is also possible to perform communication with the device 30, and the method is not limited to a specific method. The point is that it is only necessary to know which remote controller has requested the character information. However, in the present invention, such information is referred to as identification information, and in the description of the embodiment, the term remote control ID will be used for easy understanding.

The processing shown in FIG. 6 is different from the processing shown in FIG.
And that the processing content of step S21 is changed to transfer the character information together with the remote control ID as shown in step S53, and the other processing is the same.

That is, in the process of FIG.
Is transmitted to the receiver 21 together with the channel designation information of the teletext, the remote control ID is also transmitted from the remote controller 30 to the receiver 21. This remote control ID
Is transmitted, in particular, there are a plurality of remote controllers 30, and any one of the plurality of
When transmitting information or an instruction to the remote controller 1, the remote controller 30 assigns the remote control ID assigned to the remote controller 30 together with the transmission of the information or the instruction in order to identify which remote controller 30 transmits the information or the instruction. It is automatically transmitted from the remote controller 30 to the receiver 21.

As shown in step S11 of FIG. 6, when the character information control unit 8 of the receiver 21 detects that there is a display instruction of character information from the remote controller 30, the character information control unit 8 transmits the character information together with the instruction information from the remote controller 30. Then, the remote controller ID is obtained (step S43), whereby the remote controller 30 from among the plurality of remote controllers 30 is identified. When the character information data for one screen read from the storage device 9 is transferred from the display control unit 7 to the remote control transmission unit 12 via the character information control unit 8 in the same manner as in the processing of FIG. , The remote control ID is also transferred (step S53).

The character information data for one screen and the remote control ID transferred to remote control transmitting section 12 in this manner are transmitted from remote control transmitting section 12 to each remote control 30. In each remote controller 30, the received information is analyzed by the control device 17, and it is determined whether or not the remote controller ID included in the information matches its own remote controller ID. Only the remote controller 30 whose remote controller ID matches the remote controller ID assigned to itself receives the character information for one screen from the receiver 21, then temporarily stores the character information in the storage device 18 and temporarily stores the character information in the display device 15. It is displayed.

FIG. 7 shows an input of an instruction to display character information to remote controller 30 which has issued a character information display instruction among a plurality of remote controllers in the above-described processing of FIG. 6 is a flowchart specifically showing processing of the control device 17 of the remote controller 30 in the case. As shown in FIG. 7, the control device 17 of the remote controller 30 that attempts to display character information always monitors whether there is an input from the input unit 16 (steps S61 and S63). If there,
The remote controller ID is added to the control signal including the input information (step S65), and the control signal with the remote controller ID is transmitted from the signal transmitter 13 of the remote controller 30 to the receiver main body 21 (step S67). . This process is the same as the above-described process of FIG. 4 except that a remote control ID is added.

FIG. 8 shows the control of the remote controller 30 when the character information transmitted from the receiver 21 in the above-described processing of FIG. 6 is a flowchart specifically showing a process of the device 17. In FIG. 8, each control device 17 of the plurality of remote controllers 30 constantly monitors the reception status of the signal receiving unit 14 and checks whether or not the signal receiving unit 14 has a display data signal from the receiver 21. When the presence of the display data signal is detected (step S71), the information received by the signal receiving unit 14, ie, in this example, the remote control ID received together with the character information
And checks whether or not this remote control ID matches the remote control ID assigned to itself (step S73). If the remote control IDs do not match, the process ends. If the remote control IDs match, the character information received together with the remote control ID is temporarily stored in the storage device 18.
And then display it on the display device 15 (step S75).

Next, with reference to the flowchart shown in FIG. 9, the processing in the character information control section 8 of the receiver 21 when character information is input from the input means 16 of the remote controller 30 to the receiver 21 will be described. This processing is performed, for example, when character input is required in response to an inquiry from a broadcasting station or a server device of the Internet in a text broadcast or the Internet or the like. It corresponds to waiting for input.

The character information control unit 8 of the receiver 21 monitors whether a character is input from the remote controller 30 via the input control unit 10 (steps S81 and S83), and
When a character is input from 0, control is performed so that this character information is input to the corresponding display field (step S8).
5). The display field in the input of the character information to the corresponding display field is the receiver 2 when the receiver 21 is designated by an instruction from the remote controller 30.
This is a corresponding display field of the first display device 5, and a corresponding display field of the display device 15 of the remote controller 30 when the remote controller 30 is designated.

FIG. 10 is a flowchart showing the input processing of the character information in the remote controller 30 with respect to the processing shown in FIG. That is, the controller 17 of the remote controller 30
Monitors the input from the input means 16 at all times and determines whether or not this input information is a control signal (step S).
91, S93). If the input information is not a control signal,
The input information is sequentially displayed on the temporary display section 16d of the display device 15 while being sequentially stored in the storage device 18 (step S).
95). As a result, when the input information from the display device 15 of the remote controller 30 is ordinary character information that is not a control signal, for example, a person name, a place name, an age, and other ordinary information responding to an inquiry from a broadcast station, an Internet server device, or the like. In the case of the character information, the input character information is displayed as it is on the temporary display section 16d of the input field 16a of the input means 16, for example, "Taro Toshiba" as it is.

In this way, the character information is sequentially displayed on the temporary display section 16d by the input means 16 and input, and after the desired character information is input, for example, the "determination" of the control information section 16b of the input means 16 is performed. Alternatively, completion of the input is instructed by inputting a control signal such as “execute” (not shown). When the input completion instruction, that is, the input of the control signal is identified by the control device 17 (step S93), the input means The character information from 16 is transmitted to the control device 17
Is transmitted from the signal transmission unit 13 to the receiver 21 under the control of (step S97).

Next, referring to the flowchart shown in FIG. 11, a case where a program different from this program is displayed on the display device 15 of the remote controller 30 without changing the screen of the program currently being viewed on the receiver 21. The process in the television control unit 4 of the receiver 21 will be described.

In FIG. 11, the television control unit 4 of the receiver 21
Checks whether there are a plurality of program display instructions including an instruction from the remote controller 30 (step S101).
If there are a plurality of program display instructions, it is checked whether or not the display destination of the sub-program, which is not the main program, displayed on the display device 5 of the receiver 21 is the remote controller 30 (step S103). If the display destination of the sub-program is the remote control 30, the remote control transmission unit 12
Is transferred to the receiver (step S107). However, if the display destination of the sub-program is not the remote controller 30 but the receiver 21, the display switching / synthesizing unit 3 is transmitted from the television control unit 4. The data of the designated program is transferred to the display device 5 (step S105).
The sub-program is displayed by switching to a plurality of small screens.

When the data of the sub-program is transferred, the remote-control transmitter 12 of the receiver 21 transmits the data of the sub-program to the signal receiver 14 of the remote controller 30. The remote controller 30 temporarily stores the data of the sub-program received by the signal receiving unit 14 in the storage device 18 under the control of the control device 17, and then displays the data on the display screen 15a of the display device 15. In this way, the desired sub-program can be displayed on the display device 15 of the remote controller 30 for viewing without interrupting the screen currently displayed by the receiver 21.

Next, with reference to the flowchart shown in FIG. 12, a description will be given of the processing in the character information control section 8 for inputting character information from the input means 16 of the remote controller 30 and confirming it on the display screen 15a of the remote controller 30. . In this process, the character string input by the input means 16 of the remote controller 30 is once transmitted to the character information control unit 8 of the receiver 21, and the screen information on which the processing for the input of the character string has been performed in the receiver 21 is transmitted to the remote controller 30. The content is received at 30 and its contents are confirmed.

In this process, when inputting character information from the remote controller 30, first, as shown in FIG.
In the display processing of the character information from 1 to the remote controller 30, an input field is displayed on the display screen 15a of the remote controller 30 as shown by a rectangular box in FIG. The character input process is performed as shown in FIG. 13, whereby the character input in response to, for example, an inquiry “What is your name?” As shown in FIG. 13A is performed, for example, as shown in FIG.
Such a response input is performed.

That is, step S of the processing shown in FIG.
At 111, the remote controller 30 is used until the screen is completed.
Is input to the input field displayed on the display screen 15a of FIG. 10 by the processing of FIG. 10, and in the above example of "Ichiro Tanaka", the character information input from the input means 16 of the remote controller 30 is first input. "Tanaka ..." is sequentially input to the temporary display section 16d of the means 16, for example, "Tanaka Ichiro" is input and displayed on the temporary display section 16d, and then "Conversion" of the control information section 16b is touched. Then, “Tanaka Ichiro” displayed on the temporary display section 16d is converted into “Kanji” by “Ichiro Tanaka” and the temporary display section 16d
Is displayed (step S113). After the input of the character information in this manner, for example, when a touch operation is performed on a touch button display such as “confirm” or “execute” (not shown) in the control information section 16b, the character information “Ichiro Tanaka” is The signal is transmitted from the signal transmission unit 13 of the remote controller 30 to the receiver 21 as shown in step S97. In the receiver 21, the display control section 7 is received by the remote control receiving section 11 via the input control section 10 and the character information control section 8.
Supplied to When receiving the character information, the display control unit 7 displays the information obtained by processing the input of the character information on the display device 5 when the display device 5 of the receiver 21 does not display another program or the like. However, when the display device 5 is displaying another program or the like, the display control unit 7 transfers the display control unit 7 to the remote control 30 again via the character information control unit 8 and the remote control transmission unit 12 (step S115). Remote control 30
The received character information can be received by the signal receiving unit 14 and displayed on the display screen 15a of the display device 15 under the control of the control device 17, for example, as shown in FIG. That is, the information input by the input means 16 of the remote controller 30 can be reflected and confirmed on the display device 15 of the remote controller 30.

When the input screen is completed in step S111 in FIG. 12, information to be transmitted to the outside of the input screen, for example, information “Ichiro Tanaka” in FIG. The text information is transmitted from the character information communication unit 19 to an external device such as a broadcasting station or an Internet server device via the communication line 25.

In the above embodiment, the receiver 21
Of the display device 5 can be constituted by, for example, a CRT,
The display device 15 of the remote controller 30 can be composed of, for example, liquid crystal, but is not limited to this, and various display means can be used. Also, the receiver 21
