The user can get an overview of the program-related information data that can be acquired from the display on the display unit 242. Further, the context information display processing unit 39 causes the display unit 242 to display what context information has been transmitted after the context information has been transmitted to the context conversion server 2.

[0061] The program related information data processing unit 301 analyzes the program related information data received from the context conversion server 2 via the transmission / reception processing unit 36, and displays the program related information data. The display processing in the part 302 can be performed. For example, when program related information data is described in XML (Extensible Markup Language) format, which is SVG (Scalable Vector Graphics) format, the program related information data processing unit 301 uses SVG (XML parser) etc. A format analysis process is performed to form a tree structure, and a program related information data display unit 302 performs a conversion process to a drawing command so that the drawing Z display process can be performed.

The program related information data processing unit 301 also performs a process for a user operation performed on the program related information data operation receiving unit 303. More specifically, the program related information data processing unit 301 performs processing such as enlargement / reduction or switching processing of the display range such as scrolling and panning. When the program related information data is divided into a plurality of pieces, the program related information data processing unit 301 acquires an unacquired unit through the transmission / reception processing unit 36. Furthermore, when program related information data is provided in XML format such as SVG format, if link information to the web page is embedded, the program related information data processing unit 301 selects the context conversion server 2. In addition to notifying the linked link, it is installed in the mobile communication terminal 1 and also cooperates with an application such as a web browser to perform application startup processing. The embedded link information is not limited to the URL of the WEB page, but can also specify a specific function or application on the mobile communication terminal 1 in a format such as device: ZZ. In such a case, the program related information data processing unit 301 cooperates with the designated application to perform application activation processing.

[0063] Generally, software executed by the control unit 22 is stored and distributed in a recording medium such as the external storage unit 232, and the recording medium force is read by a memory slot or the like of the mobile communication terminal 1, and is described above. This is executed by the control unit 22. The hardware itself of the mobile communication terminal 1 described above is general. Therefore, it can be said that the most essential part of the present invention is software recorded on a recording medium such as the external storage unit 232.

FIG. 4 shows a specific example of the configuration of the context conversion server 2 that works on the present embodiment.

Referring to FIG. 4, the terminal data transmission / reception unit 41 communicates with the mobile communication terminal 1 via the computer network 5 in context information, user action context information, and a program. Send and receive related information data. The terminal data transmission / reception unit 41 includes various communication protocols required for the computer network 5 to which the mobile communication terminal 1 and the context conversion server 2 are connected, such as TCP / IP and http. The protocol used by the terminal data transmitter / receiver 41 may be a uniquely defined application protocol.

[0065] The context information processing unit 42 analyzes the context information received from the mobile communication terminal 1, and extracts information for specifying the content of the program currently being viewed on the mobile communication terminal 1 that is the context information transmission source. The program content information is acquired. More specifically, the context information processing unit 42 extracts channel history information, time information, location information, or movement history information indicating a history of communication with the communication base station included in the context information. The recorded title may be the program name itself. The context information processing unit 42 acquires the program content information currently being viewed on the mobile communication terminal 1 that is the context information transmission source to the program content service server 3 via the program content server inquiry processing unit 43.

[0066] The context information processing unit 42 also searches the context conversion rule DB 45 via the context conversion rule DB search unit 44 based on the program content information acquired via the program content server inquiry processing unit 43. Based on the search result, the context information processing unit 42 performs processing for generating user action context information to be transmitted to the mobile terminal 1 that is the context information transmission source. More specifically, for example, the context information processing unit 42 uses a program category such as drama or -use included in the program content information received from the program content service server 3 as a parameter, and uses the context conversion rule DB. The context conversion rule DB45 is searched through the search unit 44. The context information processing unit 42 generates user action context information based on the information provided from the context conversion rule DB search unit 44.

[0067] The context information processing unit 42 further sends the information service server inquiry processing unit 46 to the information service server based on the response to the user action context information received by the mobile communication terminal 1 through the terminal data transmission / reception unit 41. Make an inquiry request. More specifically, the context information processing unit 42 receives from the mobile communication terminal 1. Based on the user action included in the response to the one-action context information, the context conversion rule DB 45 is searched through the context conversion rule DB search unit 44 to extract the corresponding search combination rule. The context information processing unit 42 also extracts action-related data included in the response to the user action context information as a parameter, and sends an inquiry request to the information service server 4 to the information service server inquiry processing unit 46. To do.

[0068] Based on the program content information query received from the context information processing unit 42, the program content server query processing unit 43 queries the program content service server 3 and the program content information via the computer network 5 and the program content. Information acquisition processing is performed. The program content server inquiry processing unit 43 is composed of one or more search execution modules (described later). The program content server inquiry processing unit 43 uses the SOAP (Simple Object Access Protocol) and WSDL (Web services Description Language) required for inquiring program content information with the program content service server 3 and acquiring program content information. No, it is realized by Web services such as REST (Representational State Transfer).

[0069] The context conversion rule DB search unit 44 provides an interface for realizing the search or update operation of the context conversion rule DB 45. The context conversion rule DB search unit 44 receives the search parameters from the context information processing unit 42, searches the context conversion rule DB 45 using the parameters, and finds the search results corresponding to the received parameters. Return to the context information processing unit 42. The context conversion rule DB search unit 44 also receives parameters to be applied to the combination of searches described in the context conversion rule DB 45 from the context information processing unit 42 as necessary. Update conversion rule DB45. The context conversion rule DB search unit 44 is provided in a query language for a standard RDBMS (Relational Database Management System) such as SQL (Structured Query Language).

[0070] Further, the context conversion rule DB search unit 44 may perform the following processing. The first process is a process for searching the context conversion rule DB 45 in advance based on the program content information acquired via the program content server inquiry processing unit 43. This first place It is desirable that the processing is performed at the timing when the program of each broadcasting station is switched. The context conversion rule DB45 search must be based on the context information (for example, program genre) obtained from the program content information capability. The second process is a process of generating response information to the user action context to be transmitted to the mobile communication terminal 1. The third process is a process of temporarily storing as a cache in the context conversion rule DB search unit 44.

[0071] By executing the first processing power up to the third processing, it is possible to shorten the response time even when traffic of user action context information transmitted from the mobile communication terminal 1 is concentrated. . The context conversion rule DB search unit 44 deletes the information temporarily stored as a cache when the program switched when the first process is completed is completed. Therefore, only the cache of the program being broadcast is temporarily stored, so that it is possible to keep the memory consumption to the minimum necessary, and the search inside the cache becomes fast.

[0072] Context conversion rule DB45 is a search combination rule corresponding to a combination of one piece of information (eg, user action context) included in the context information, one piece of information (eg, program category) contained in the program content information, and information. This is a database that describes a model of program related information data used when creating program related information data. Context conversion rule DB45 is a database for converting context information into search combination rules. The name of the search expression, the domain of the search destination site as the contents of the search expression, parameters such as keywords for searching the domain of the search destination site, and the search results and data format obtained from the search destination site It is defined as a search combination rule. The information stored in the context conversion rule DB 45 is preferably registered in advance by a mobile phone carrier, Internet connection carrier, information service carrier, etc., but this is not restrictive.

The information service server inquiry processing unit 46 makes an inquiry request to the information service server 4 based on the request content received from the context information processing unit 42, and acquires related information data. More specifically, the information service server inquiry processing unit 46 receives the search combination rule ID and predetermined parameters from the context information processing unit 42. Based on the search combination rule ID, the information service server query processing unit 46 executes the search execution module with the parameters as arguments in accordance with the search combination rule extracted by searching the context conversion rule DB45, and A request for acquiring related information data is sent to the server 4, and related information data is acquired from the information service server 4. The information service server inquiry processing unit 46 includes one or more search execution modules (described later). The information service server query processing unit 46 is realized by SOAP, WSDL, REST and!, And the Tatsu Web service necessary for inquiring related information data with the information service server 4 and acquiring related information data.

[0074] The intermediate data conversion unit 47 performs processing for converting the related information data acquired from the information service server 4 by the information service server inquiry processing unit 46 into a format that can be processed by the program related information data creation unit 48. . More specifically, the intermediate data converter 47 maps the items of related information data acquired from the information service server 4 to items that can be referred to in the program related information data template.

[0075] The program related information data creation unit 48 combines the related information data acquired from the information service server 4 with the program related information data template stored in the program related information data template DB40, thereby generating program related information data. Create For this reason, the related information data acquired from the information service server 4 needs to be in a format that can uniquely refer to the program related information data template. For example, if the information related to the headline of program-related information data is referred to by the item “title> in the program-related information data template title>, the heading to be obtained from a certain information service server 4> The headline> item that you want to obtain from the service server 4 is converted to the title> item by using processing such as XSLT (Extensible Stylesheet Language Transformations).

The program related information data creation unit 48 uses the output of the intermediate data conversion unit 47 based on the information of the program related information data template stored in the context conversion rule DB 45 to transmit to the mobile communication terminal 1 Generate related information data. More specifically, the program-related information data creation unit 48 acquires template data corresponding to the search combination rule ID from the program-related information data template DB 40, and outputs the output of the intermediate data conversion unit 47 to the template data. The process of combining is performed to create program related information data. The program-related information data creation unit 48 uses the program-related information data template stored in the context conversion rule DB 45, for example, to “examine” as user action context information when watching a “song program”. If you select `` Create encyclopedia style '' program-related information data, or if you select `` Listen '' as user action context information while watching `` Song program '', Program-related information data can be created in a “CD catalog style”.

The program related information data created by the program related information data creating unit 48 is stored in the created program related information data storage unit 49. When exactly the same context information is transmitted from the mobile communication terminal 1 or when there is a request for retransmission of program related information data from the mobile communication terminal 1, the created program related information data storage unit 49 By using the stored program information data, the above processing can be omitted.

[0078] The program-related information data model DB 40 holds a model of program-related information data corresponding to the search combination ID. More specifically, the program-related information data template DB40 determines the layout, background color, character color, and character size of related information data required for creating program-related information data for each search combination ID. It holds the template data that describes the layout information such as the background image and decoration and the display order on the mobile communication terminal 1. The template is described in the SVG format, for example.

FIG. 5 is a diagram showing a specific example of the structure of the context conversion rule database 45 of the context conversion server 2 according to the present embodiment.

[0080] The search combination rule 52 is given ID 51, which is a unique identifier for specifying the search combination rule. Program related information corresponding to the search combination rule 52 Data template ID stored in the DB40, element 54 of the program content information to which the search combination rule 52 can be applied (more specifically, program category), user action The extraction conditions for the information to be acquired in connection with the user action context from the context 55 and the mobile communication terminal 1 are associated with the search combination rule 52.

[0081] The search combination rule 52 uses a predetermined description method, the name of the search expression, and the contents of the search expression as key words for searching the domain of the search destination site and the domain of the search destination site. Parameters such as search mode, search results obtained from the search destination site, and their data formats are specified. Although not particularly limited, the “search combination rule 52” can correspond to class information in an object-oriented language. In the example of Fig. 5, the search destination domain is described in the form of referring to the ID as the search execution module ID. The URL that indicates the actual location of the search destination, the data format of the search keyword, and the number of requested related information data can be further specified in the definition of the search execution module that can be referred to by ID. Multiple searches can be executed by listing multiple search execution module IDs.

Furthermore, in a certain search expression, the search result of another search expression can be used as a search parameter. For example, as shown in FIG. 5, in the search expression “encyclopedia search”, the search execution modules checkPedia01, checkPedia02, and checkPedia03 that make up the search expression are search expressions for acquiring performer names. Search execution module of getPerson You can search using personnames that is the search result of NameOl as a parameter. In this way, the search can be performed in the form of “search for encyclopedia information on performers” by indicating the order of search in a predetermined description format and the interrelationship of search expressions as constituent elements.

FIG. 6 is a diagram showing a specific example of a search execution module definition included in the search combination rule description 52 of FIG. 5, more specifically, an interface definition of the search execution module. In FIG. 6, the getPersonNameOl service that searches for performers by “acquire performer name” described in the search combination rule 52 of FIG. 5 is defined.

The definition of the search execution module is given a search execution module ID 61 that can uniquely specify the search execution module in the search combination rule description. As shown in FIG. 6, in the search execution module definition, the location of the search destination domain or the location 62 of the service that is the transmission destination of the search request provided by the search destination domain can be described in the URL format, for example.

Further, in the search execution module definition, input data 63 for searching the search destination domain can be defined. More specifically, the identification ID and data format of the parameter sent to the search request destination URL are described in the search execution module definition. You can. Here, the channel information being viewed is specified as an integer Ch parameter, and the viewing time is specified as an integer Time parameter in the same way, and the viewing area (base station address) is displayed in an arbitrary character string format. Specify with region ^, parameter.

The input data 63 is applied as a parameter based on the context information received from the mobile communication terminal 1 by performing a predetermined procedure to be described later. As described above, the context information is information stored in the user's terminal or information capable of acquiring a predetermined functional capability in the user's terminal. This makes it possible to collect related information data according to the user's situation from the information service server 4.

[0087] The search execution module definition can further define the output data 64 of the search execution module, which is related information data. More specifically, the identification ID indicating the output contents of the search execution module, the same data format It is also possible to specify the mapping with the contents received as a response to the meter sent to the search request destination URL. Here, if the content received as the item “acting>” from the information service server 4 is output as personnames in arbitrary string format, the definition is made! /

FIG. 7 is a diagram showing a specific example of the search combination rule description 52 of FIG. 5 by the XML description. The search combination rule description combines two or more search execution modules whose definitions are shown in Fig. 6 to search for program related information.

First, the search module getPersonNameOl obtains a list of program performers names personnames from the program content service server 3 using the primary context information sent from the user. Personnames can be reused as a parameter of the search execution module described in the rule description. Next, the search module checkPediaOl sets the performer name list personnames as a keyword parameter and searches for information related to the performers. At this time, the search module checkPediaOl requests title (title), description (text), and picture (image) as items included in the output data. Furthermore, another search execution module getSongtitleOl sets a performer name list personnames as a keyword parameter, and retrieves incoming music melody of performers. At this time, the search module checkPediaOl is included in the output data. Request titles (title, title) and ringtones (ring melody) as required items.

Here, transmission / reception of context information between the mobile communication terminal 1 and the context conversion server 2 will be described. Here, as a method for the user to send the context information to the context conversion server 2, the primary context information (described later) and the secondary context information (described later) are divided into two times, that is, the mobile communication terminal 1 and the context. An embodiment in which a method of performing communication twice between conversion servers 2 is selected will be described. Note that the context information communication method is not limited to two round trips, but may be sent once as described later. Or, the communication method of context information is to communicate 3 times or more.

[0099] The user action context information that can be selected by the user is not limited to one. The user selects multiple options such as HTML (HyperText Markup Language) checkboxes and sends the user action context information as a single piece of context information to the mobile communication terminal 1 and the context conversion server 2. It's good.

[0100] When the software button is selected, the pressed button image is displayed. Further, when the selected software button is pressed while a plurality of software buttons are selected, the context information power is generated based on the user action context information of the selected software button and transmitted to the context conversion server 2.

FIG. 12 shows an example of a record extracted from the context conversion rule DB 45 in the context conversion server 2.

[0102] In FIG. 11, a broadcast service is watching a program classified as a song program as a program category. When a program-related information data acquisition request is transmitted by a user operation, the context conversion server 2 analyzes the context information (primary context information) included in the program-related information data acquisition request, and Through communication with the service server 3, the user is informed that the category of the program currently being viewed is a song program. The context conversion server 2 extracts the record that can be extracted with “program category = song program” from the context conversion rule DB 45 for the mobile communication terminal 1 that has requested acquisition of program-related information data, and stores it in the record. Send the described user action context information.

[0103] The mobile communication terminal 1 displays the user action context information received as a response to the primary context information as options as shown in FIG. Here, by user operation When the user action context information button of “Performer” is selected from the options 84, the mobile communication terminal 1 uses the selection result to obtain context information (secondary context information) that is a response to the user action context information. Is generated and sent to Context Conversion Server 2.

The context conversion server 2 analyzes the secondary context information, and extracts a record with ID = 10 from the context conversion rule DB 45 by matching the program category column and the user action column shown in FIG. As described above, the options provided from the context conversion server 2 are selected by the user operation on the mobile communication terminal 1 and transmitted to the context conversion server 2, whereby the context conversion rule DB45 combination rule in the context conversion server 2 is selected. Search conditions are added, the search accuracy is improved, and program-related information data that is highly convenient for the user can be provided.

FIG. 13 shows a flowchart of processing in which the mobile communication terminal 1 transmits context information to the context conversion server 2. First, the software button 82 shown in FIG. 8 is selected by a user operation.

In steps S 1001 to S 1005, control unit 22 performs processing for acquiring primary context information and temporarily storing it in a memory corresponding to internal storage unit 231. Specifically, in step S1001, the control unit 22 acquires channel information of the program being viewed and stores it in the memory. In step S1003, the control unit 22 acquires the current time information and stores it in the memory. In step S 1005, the location information acquisition unit 25 acquires the current location information of the mobile communication terminal 1 and stores it in the memory. In step S1007, control unit 22 performs determination according to the context batch transmission setting. If YES, the control shifts to the process in step S 1607 in FIG. If NO, control transfers to step S 1009. In step S1009, the mobile communication terminal 1 transmits the primary context information temporarily stored in the memory in step S1001 to step S1005 to the context conversion server 2 via the communication unit 21.

Here, the transmission method from mobile communication terminal 1 to the server is not particularly limited. For example, you may communicate with the server immediately by HT TP communication. In this case, instead of the processing from step S1001 to step S1005, the mobile communication terminal 1 includes the broadcast data processing unit 32. Information representing the program schedule included in the broadcast signal may be extracted as an EPG, and the extracted information may be transmitted. When communicating to the server immediately by HTTP communication, the broadcast data display processing unit 33 may display information on the program being broadcast according to an arbitrary application based on the information included in the broadcast signal as an EPG. Good. Instead of EPG, when information indicating the schedule of a program is included in the broadcast signal in the same manner as EPG, the information may be extracted and transmitted by control unit 22. The mobile communication terminal 1 may display information on the program being broadcast based on the information. When the mobile communication terminal 1 displays information according to the application, the information of the program being broadcast may be displayed according to the browser. Also, when transmitting from the mobile communication terminal 1 to the server, the transmission / reception processing unit 36 configures the body of the email or the attached file including the primary context information and sends it to the server as an email. Good. In this case, the title of the e-mail may include “Create Program Related Data” and other information that identifies the program being viewed.

In step S 1011, mobile communication terminal 1 receives user action context information from context conversion server 2. In step S1013, the control unit 22 analyzes the received user action context information and displays it on the screen. Here, the screen display in the state shown in FIG. In step S1015, the mobile communication terminal 1 accepts selection by user operation of user action context information via the operation unit 241.

In step S1017, control unit 22 collects data in portable communication terminal 1 associated with the selected user action context information. For example, data extracted from a browser history card installed in the mobile communication terminal 1 that includes a specific URL, file name list data of an image file stored in the data folder, mobile communication terminal 1 Data that represents information on the location of data, and data such as viewing history data of broadcasting applications correspond to collection targets. In the case of the present embodiment, the collected file name list data is data representing the file name, the file size, and the file data format. Note that the content of the collected file name list data is not particularly limited, and data other than these data may be included, or at least a part of these data may be missing. [0110] In step S1019, the control unit 22 stores the collected data in the terminal in the internal storage unit 231 as action-related data of the user action context information. In step S1021, the mobile communication terminal 1 sends the user action selected in step S1015 and the action-related data stored in the internal storage unit 231 in step S1019 via the communication unit 21 to the secondary context information. To the context conversion server 2. In step S1023, the control unit 22 displays the transmitted menu and ends the process.

14 to 16 show the contents of data exchanged between the mobile communication terminal 1 and the context conversion server 2 described in the flowchart of FIG.

FIG. 14 is a specific example of the primary context information transmitted in step S1009 of FIG. The primary context information includes, as channel information, 10CH, which is the channel number of the broadcast service program that was being viewed when the software button 82 was pressed. The primary context information includes time information when the software button 82 is pressed as time information. The primary context information includes, as regional information, position information calculated by a GPS device mounted on the terminal and position information based on information on base station antenna power with which the terminal is communicating. The primary context information includes information for identifying the terminal type, such as the model name of the mobile phone and the software version number, as the terminal type. The primary context information includes JPEG (Joint Photographic Experts Group), rendering formats such as HTML and SVG as the program-related information data format that can be displayed. The primary context information includes information that uniquely identifies the terminal, such as an e-mail address or IP address, as a program-related information data notification destination.

[0113] The primary context information includes history information that the terminal has moved for a predetermined period as the movement history. More specifically, the history information is a history of communication between the mobile communication terminal 1 and the base station during the period when the time force when the software button 82 is pressed is also traced back for a certain period, and includes the address of the base station or the latitude of the base station. Contains longitude information. In addition, the mobile communication terminal 1 transmits a channel number, region information, and time information as primary context information. When the program guide function is available, the mobile communication terminal 1 omits these, and the context information is changed from the program name that can be obtained from the program guide function and the information on the WEB page of the program as program identification information. It may be sent to the replacement server 2.

FIG. 15 shows user action context information transmitted from the context conversion server 2. Here, six user action context information items of “see”, “examine”, “buy”, “listen”, “enjoy”, and “collect” are described. Furthermore, the user action context information of “examine” and “view” includes the definition of the extraction condition of the action related data stored in the terminal. The mobile communication terminal 1 extracts information stored in the terminal according to the action-related data extraction condition definition.

FIG. 16 shows the secondary context information transmitted in step S1021 of FIG. In this case, two user action context information items “examine” and “view” are selected. Further, the secondary context information includes information on favorite bookmarks of browsers installed in the mobile communication terminal 1 as action-related data of “examine”. Further, the secondary context information includes an image file stored in the data folder of the mobile communication terminal 1 as action-related data of “view”. Incidentally, if “local”, which will be described later, is included in the secondary context information as the user action context information, and “local” is selected in step 1015, the secondary context information is “local”. It includes information on the location of the mobile communication terminal 1 associated with the user action context information.

FIG. 17 shows a series of processing flowcharts until the context conversion server 2 receives the primary context information and also transmits the program-related information data to the mobile communication terminal 1.

[0117] First, in step S1201, the context conversion server 2 receives and analyzes primary context information. In step S1203, the context conversion server 2 makes an inquiry to the program content service server 3 through the information service server inquiry processing unit 46 based on the channel information, time information, and region information included in the primary context information. To do. The program content service server 3 is a server that provides information on a so-called program guide, and can specify a program from channel information, time information, and regional information. Accordingly, the program category such as program dramas and variety is identified and returned to the context conversion server 2. Furthermore, the program content service server 3 displays the performers of the specified program and the contents of the program content. It is also possible to provide the context conversion server 2 with the theme song of the program, the incoming song, the homepage address of the program, event information related to the program, and the like. On the other hand, when the context conversion server 2 receives information about the program name category and program WEB page that can be acquired from the program guide function installed in the mobile communication terminal 1 as the primary context information, the context conversion Server 2 does not need to access program content service server 3.

[0118] In step S1205, the context conversion server 2 searches the context conversion rule DB 45 using the program category received from the program content service server 3 in step S 1203 as a search key. The context conversion server 2 generates user action context information from the search result record (S1207). Further, the user action context information may be generated based on information that can be acquired from the program content service server 3. For example, the user action context information options shown in FIG. 11 are based on information that can be acquired from the program content service server 3, and the user action context information is generated and transmitted to the terminal. , Program homepages, events, etc. are displayed on the screen.

[0119] In step S1203, an example is shown in which channel information, time information, and region information are received as primary context information, but the content of primary context information is not limited to such information. When the context conversion server 2 receives user profile information or information about the terminal, for example, location information of the terminal by GPS, as primary context information, the generated user action context information is changed. Yo! For example, when the primary context information includes GPS information, user action context information “local” may be provided. “Local” corresponds to expressing a situation in which limited information is requested to the surrounding area based on the location information of the user.

In step S1209, the context conversion server 2 transmits the generated user action context information to the mobile communication terminal 1. In step S1211, the context conversion server 2 receives the secondary context information transmitted from the terminal camera in step S1021 in FIG. In step S1213, the context conversion server 2 analyzes the secondary context information. In step S1215, the context conversion server 2 starts from the mobile communication terminal 1. Using the user action context information included in the received secondary context information as a search key, the context conversion rule DB 45 is searched, and the corresponding search combination rule is extracted. In step S1217, the context conversion server 2 determines whether the search execution module described in the extracted search combination rule includes a search execution module to which action-related data can be applied. If YES in step S1217, in step S1219, the context conversion server 2 updates the description so that action-related data is added to the search parameters of the search execution module included in the conversion rule description. . On the other hand, in the case of NO in step S1217, the context conversion server 2 advances the control to step S1221 without updating the description of the search parameter of the search execution module.

[0121] In step S1221, the context conversion server 2 executes an inquiry to each information service server 4 according to the search execution module description described in the combination rule, and acquires related information data. In step S 1223, the context conversion server 2 converts the related information data, which is the query result, into an intermediate language. In step S1225, the context conversion server 2 acquires a program related information data template that defines layout information and the like, and synthesizes the related information data converted into the intermediate language as program related information data. In step S1227, the context conversion server 2 transmits the combined program related information data to the mobile communication terminal 1 and ends the process.

FIG. 18 shows a data exchange sequence between the mobile communication terminal 1 and the context conversion server 2. In the mobile communication terminal 1, the software button 82 is selected by a user operation while viewing a program.

[0123] In step S1301, mobile communication terminal 1 acquires primary context information including channel information, time information, and region information, and transmits the primary context information to context conversion server 2. At this time, the mobile communication terminal 1 may present to the user that the primary context information has been transmitted. In addition to the dialog display as shown in FIG. 22 described later, the presentation method includes blinking of light such as sound, vibration, and LED (Light Emitting Diode).

[0124] In step S1303, the context conversion server 2 adds the received primary context information. The program content service server 3 is inquired based on the channel information, time information, and regional information included. Based on the response of the program content service server 3, the program name can be specified and the category of the program can be determined.

[0125] In step S1305, the context conversion server 2 searches the context conversion rule DB 45 using the program category of the specified program as a condition, and extracts a matching record. The context conversion server 2 generates a list of user action contexts included in the extracted record, and transmits it to the mobile communication terminal 1 as user action context information.

[0126] In step S1307, the mobile communication terminal 1 displays an option for acquiring the received program-related information data on the screen based on the user action context information so that it can be selected by a user operation. When the user action context is specified by the user operation, the mobile communication terminal 1 extracts the data in the terminal associated with the user action context, and the terminal power is also converted into the context conversion server 2 as secondary context information. Send back to. At this time, the mobile communication terminal 1 may present to the user that the secondary context information has been transmitted. In addition to the dialog display as shown in Fig. 22 described later, the presentation method includes blinking of sounds such as sounds, vibrations, and LEDs.

[0127] In step 1309, the context conversion server 2 searches the context conversion rule DB45 based on the primary context information and the secondary context information transmitted from the mobile communication terminal 1, and specifies the combination rule. The search execution module description is updated accordingly. In step S1311, the context conversion server 2 executes a query to the information service server 4 according to the description of the combination rule, and acquires the query result. In step S1313, the context conversion server 2 synthesizes the query result of the information service server 4 as data for the mobile communication terminal 1, and transmits the data generated by the synthesis to the mobile communication terminal 1.

FIG. 19 is a diagram showing a specific example of a method for displaying program-related information data in the mobile communication terminal 1. The program-related information data 1401 is obtained by combining predetermined portions of the program-related information data template with the contents of intermediate data, which is related information data received from each service sano. More specifically, the program related information data is converted into intermediate data. The related information data received from the information service server 4 is composed of a set of laid out related information data 1402 laid out based on a program related information data template.

[0129] laid-out related information data 1402, and text 1411, JPEG and PNG (Portable N etwork Graphics), GIF (Graphic Interchange Format) such as an image 1412, Web sites and _We b link information indicating the location of a specific function by the service 1413, a script for executing a predetermined calculation process such as Java (registered trademark) Script, an input button 1414 to which the script is assigned, and a moving picture 1415 such as MPEG2 or MPEG4.

[0130] The layout related information data 1402 does not have to have a one-to-one relationship with the related information data acquired from the information service server 4. One layout related information data 1402 includes a plurality of related information data. May be.

[0131] The program-related information data template includes a description of the display order when the mobile communication terminal 1 displays and a description of the operation when displayed. Display order description and display order behavior can be expressed in a script using, for example, the <script> tag included in the SVG format.

[0132] Referring to FIG. 20, mobile communication terminal 1 treats layout related information data 1421, 1422, 1 423, and 1424 as a set of objects using <g> tag, and handles this <g> tag as scr. Operate from ipt to switch display with pan, switch with scrolling effect, etc., and display multiple layout related information data by using enlargement / reduction effect be able to.

[0133] Next, a case where a method in which context information is communicated once between the mobile communication terminal 1 and the context conversion server 2 is selected will be described. The context information communicated in this case is information including the primary context information and the secondary context information described above. As described above, the context information may be transmitted in three or more times.

FIG. 21 is a diagram showing a specific example of screen display on display unit 242 of mobile communication terminal 1 when program-related information data is acquired. In FIG. 21, the program 81 by the broadcast service is displayed in the center of the screen. In addition, a software button 82 for requesting acquisition of program-related information data is displayed at the lower right of the screen. The mobile communication terminal 1 executes the functions of various applications by accepting user operations through the operation unit 241. User operations may be accepted by the combination of the cursor keys and the enter button. Can be assigned to any hardware button! /, And can be assigned to a selection operation with a pointing device such as a mouse or pen touch panel! /.

When the user wants to acquire program related information data related to a program, the user performs an operation on the operation unit 241 assigned to the software button 82 displayed as “Related Information”. When such an operation is performed, the screen display on the mobile communication terminal 1 transitions to the state shown in FIG. In this case, on the screen of the mobile communication terminal 1, a program related information data acquisition column 1503 that is information related to acquisition of program related information data is displayed. In the program related information data acquisition field 1503, context information 1504 is displayed.

[0136] When the operation on the operation unit 241 assigned to the software button 82 is executed, the mobile communication terminal 1 transmits a program-related information data acquisition request to the context conversion server 2. When this acquisition request is transmitted, the context conversion server 2 analyzes the context information included in the program-related information data acquisition request, and communicates with the program content service server 3 to display the program currently being viewed by the user. Know that the category is a song program. The context conversion server 2 extracts a record that can be extracted with “program category = song program” from the context conversion rule DB 45 based on the request for acquiring the program related information data, and program related information data among the extracted records. User action context information corresponding to the acquisition request is transmitted to the mobile communication terminal 1.

[0137] The context information 1504 "inspect (store) listen (ringtone)" shown in FIG. 22 is set by the user based on a menu displayed when the setting button 86 is pressed. The setting button 86 in FIG. 22 is a software button for transitioning to a screen (FIG. 23) for performing settings related to acquisition of program-related information data of the broadcast service receiving application or program-related information data acquisition application.

FIG. 24 is a diagram showing a screen when setting is made so that context information is collectively transmitted from mobile communication terminal 1 to context conversion server 2 on the setting screen of FIG. This figure is also a diagram representing each item specified by the context information. When the column “Send user action related information” is selected with focus 87 and the user performs a predetermined operation, the screen display on mobile communication terminal 1 transitions to the state shown in FIG. [0139] When the user performs a predetermined operation in the state of FIG. 24, the focus 87 moves. When the item is selected by the focus 87, the mobile communication terminal 1 can change the setting of the selected item to other settings as well as the default setting power.

[0140] Each item shown in Fig. 24 is classified into an item with a check box, an item without a check box !, and an item. When the former item is selected with focus 87, the check box image changes according to the user's operation. The check box pattern corresponds to whether the item is valid or not. When the latter item is selected with focus 87, a pull-down menu is automatically displayed. Each item included in the pull-down menu can be selected with the focus 87. However, among those items, the items that are displayed light cannot be selected with the focus 87.

[0141] When the user performs an operation on the operation unit 241 assigned to the confirm button 88 displayed as "OK", the screen display on the mobile communication terminal 1 transitions to the state shown in FIG. Also, data rewriting for each item shown in FIG. 24 is performed inside the mobile communication terminal 1.

[0142] Even when the user performs an operation on the operation unit 241 assigned to the cancel button 89 displayed as "Return", the screen display on the mobile communication terminal 1 transitions to the state shown in FIG. The However, data rewriting is not performed for each item shown in FIG.

[0143] When the user performs an operation on the operation unit 241 assigned to the confirm button 88 during the period in which the screen display on the mobile communication terminal 1 is in the state shown in FIG. Transition to the state of Fig. 21. In addition, processing for transmitting the data shown in FIG. 29 as an electronic mail is performed inside the mobile communication terminal 1.

[0144] When the user performs an operation on the operation unit 241 assigned to the cancel button 89 while the screen display on the mobile communication terminal 1 is in the state shown in FIG. 29, the screen on the mobile communication terminal 1 is also displayed. The display transitions to the state shown in FIG. However, the process of sending the data shown in Fig. 29 as an e-mail is not performed.

FIG. 25 shows a flowchart of processing in which the mobile communication terminal 1 transmits context information to the context conversion server 2. The processing up to step S 1007 is as described above. In step S1609, the controller 22 controls each item displayed on the screen shown in FIG. It is determined whether or not there are valid items. If YES, control transfers to step S1 611. If NO, control transfers to step S1613.

In step S 1611, control unit 22 stores user action context information in the internal storage unit 231 for the item determined to be valid in step S 1609. In step S1613, the mobile communication terminal 1 displays an error on the display unit 242 and ends the process.

In step S1615, control unit 22 determines whether or not action-related data is set in the user action context information stored in internal storage unit 231. If YES, control transfers to step S1617. If NO, control transfers to step S1619. In step S1617, the control unit 22 stores the set value of the action related data in the internal storage unit 231. In step S1619, the control unit 22 stores data representing “NULL” in the action context. In step S1621, the mobile communication terminal 1 transmits context information to the context conversion server 2 via the communication unit 21. In step S1623, the mobile communication terminal 1 displays the transmitted menu on the display unit 242 and ends the process.

FIG. 26 shows the contents of the context information exchanged between the mobile communication terminal 1 and the context conversion server 2 described in the flowchart of FIG. Each information constituting the context information is the same as that of the primary context information and the secondary context information described above.

FIG. 27 shows a series of processing flowcharts until the context conversion server 2 receives the context information and transmits the program-related information data to the mobile communication terminal 1 as well.

[0150] First, in step S1801, the context conversion server 2 receives and analyzes the context information. In step S 1803, the context conversion server 2 makes an inquiry to the program content service server 3 based on the channel information, time information, and area information included in the context information. The program content service server 3 is a server that provides information on a so-called program guide, and can specify a program from channel information, time information, and regional information. Accordingly, the program content service server 3 discriminates the power category of the program such as the drama or variety of the program, and returns the result of the discrimination to the context conversion server 2. further, The program content service server 3 provides the context conversion server 2 with the performers of the specified program, a synopsis of the program content, the theme song or inserted song of the program, the address of the program homepage, event information related to the program, etc. May be.

In step S1809, the context conversion server 2 refers to the context conversion rule DB 45 using the user action and the program category received from the program content service server 3 in step S 1803 as search keys. After the reference, the context conversion server 2 determines whether there is a rule corresponding to the combination of the user action and the program category. If YES, control transfers to step S 1813. If NO, control transfers to step S 1819. In step S1813, the context conversion server 2 determines whether the search execution module described in the extracted search combination rule includes a search execution module to which action-related data can be applied. If YES, control transfers to step S 1815. If NO, control proceeds to step S 1817 without updating the search parameter description of the search execution module.

[0152] In step S1815, the context conversion server 2 updates the description so that action-related data is added to the search parameters of the search execution module included in the conversion rule description. In step S1817, the context conversion server 2 sets the template ID to the template “no applicable parameter”. In step S1819, the context conversion server 2 creates program related information data “No related data”. In step S1821, the context conversion server 2 executes an inquiry to each information service server 4 according to the search execution module description described in the combination rule, and acquires related information data. In step S1823, the context conversion server 2 converts the related information data as the query result into an intermediate language. In step S1825, the context conversion server 2 acquires a program related information data template that defines the information outside the layer, and synthesizes the related information data converted into the intermediate language as program related information data. In step S1827, the context conversion server 2 transmits the synthesized program-related information data to one mobile communication terminal and ends the process.

[0153] FIG. 28 shows a data exchange sequence between the mobile communication terminal 1 and the context conversion server 2. Indicates In the mobile communication terminal 1, the software button 82 is selected by a user operation while viewing a program.

[0154] In step S1901, the mobile communication terminal 1 uses the user action context for acquiring channel information, time information, region information, and program related information data, and data in the terminal associated with the user action context. To extract. The mobile communication terminal 1 sends the extracted data back to the context conversion server 2 as context information.

[0155] In step S1903, the context conversion server 2 makes an inquiry to the program content service server 3 based on the channel information, time information, and area information included in the context information received from the mobile communication terminal 1. The context conversion server 2 can specify the program name and the program category based on the response of the program content service server 3.

[0156] In step S1905, the context conversion server 2 searches the context conversion rule DB 45 to identify the combination rule, and updates the description of the search execution module as necessary. In step S1907, the context conversion server 2 executes a query to the information service server 4 according to the description of the combination rule, and acquires the query result from the information service server 4. In step S1909, the context conversion server 2 synthesizes the query result of the information service server 4 as data for the mobile communication terminal 1, and transmits the information generated by the synthesis to the mobile communication terminal 1.

[0157] As described above, by exchanging context information between the mobile communication terminal 1 and the context conversion server 2, the search accuracy of the query result of the information service server 4 that can be received as program-related information data is It is expected that the situation will be narrowed down while taking into account the user's situation.

[0158] The power when the data exchange sequence between the mobile communication terminal 1 and the context conversion server 2 makes two round trips compared to the case of 1 round trip, because the context information that can be used by the context conversion server 2 increases. , Context conversion rules based on context information The search accuracy of search combination rules from DB45 is improved. In other words, the keys related to the user's intentions in the search results based on keywords related to vague program content. The search result is expected to be close to the image of adding a mode and narrowing down the search results.

[0159] Further, since it is used as an additional parameter for querying various information service servers via the search execution module description included in the action-related information power search combination rule description included in the context information, the query result of the information service server The search accuracy is expected to be narrowed down in consideration of the user's situation. In other words, even if the program specified by the user is the same, the user's status such as moving is included in the context information transmitted from the mobile communication terminal 1 to the context conversion server 2, and so on. By using information such as the usage status and preferences of other applications, it becomes possible to receive program-related information data that has been narrowed down in consideration of the user's status.

[0160] In addition, while viewing a program, simply press the program-related information data button at the user's favorite timing, and you can refer to the search overview of program-related information data that can be used at that timing. By selecting the one that most closely matches the user's request, a merit is achieved in that highly accurate search results can be obtained. If the number of round trips is increased to 3 round trips and 4 round trips, the search conditions on the context conversion server will increase. Related information data can be derived.

[0161] Furthermore, the mobile communication terminal 1 repeats multiple rounds of context information and narrows down the search results using AND (conjunction) of the context information, so that the user can use it with simple operations. It is possible to obtain a search result, that is, program-related information data with high accuracy according to the situation of the user.

[0162] Furthermore, in the present embodiment, when transmitting from the mobile communication terminal 1 to the context conversion server 2, the mobile communication terminal 1 communicates with the context conversion server 2 according to an arbitrary application. The effect of can be obtained. The first effect is that the program name information described in the EPG can be used as it is as information that can identify the program. The second effect is that applications can be added or replaced. [0163] Furthermore, since the application of the mobile communication terminal 1 is a browser, the mobile communication terminal 1 requests information related to which program by displaying the program that the user is viewing. If it can be presented to the user, the effect can be obtained.

[0164] Furthermore, when sending from the mobile communication terminal 1 to the context conversion server 2 according to the present embodiment, the mobile communication terminal 1 includes primary context information included in the body of an email or an attached file. When configured and sent to the context conversion server 2 as mail, the display screen at the time of data acquisition request can be in the same format as in FIG. Instead of using the same format as in Fig. 29, the TV program screen being broadcast can be displayed either on the left or right side of the mail creation screen shown in Fig. 29. In this way, if a title such as “June 26, 2006 18:00 Nara 4 Channel related information (1)” is automatically assigned, the following effects will be obtained. Is obtained.

[0165] The first effect is that it is very easy for the user to split. Users can send a request by email and receive a reply by email. The second effect is that when a search result is received as a reply to a request mail, only one search result can be found immediately by looking at the subject line. This effect is particularly meaningful when the content that can be displayed is limited, such as a mobile phone. The third effect is that the context conversion server 2 can obtain information for specifying a program only by the title without analyzing the mail text. The fourth effect is that the context conversion server 2 can easily replace the content described in the title with the information acquired from the program information server, more specifically, the program name. . This effect allows the user to see at a glance which program related information is available by looking at the title.

[0166] Further, in the program related information data acquisition menu 83, one or more user function context information can be selected, so that a plurality of searches can be executed as a result of a single data acquisition request. Since it is not necessary to make a search execution request, the procedure on the user side is reduced.

[0167] In addition, the control unit 22 of the mobile communication terminal 1 collects file name list data when collecting data in the mobile communication terminal 1 associated with the user action context selected in step S1017. As a result, the information service server 4 The data included in the data can be treated as an additional keyword, and the data format and size of the image file can be determined based on the data included in the file name list data. As a result, the range of search results desired by the user can be narrowed down.

[0168] In addition, when collecting data in the terminal associated with the user action context selected in step S1017, the control unit 22 stores information on the favorite bookmark of the browser installed in the mobile communication terminal 1, By collecting browsing history information, the information service server 4 can search by limiting the domain (site URL) to be searched. For example, when the control unit 22 uses the browser history or the above-mentioned favorite as the related information of “viewing”, the information service server 4 only displays the images provided at the sites where the history and favorites are recorded. Searching can be performed. Thereby, the mobile communication terminal 1 can display the search result of the site that the user considers convenient or the site that the user trusts as user action context information in step S1013.

[0169] Note that, as a first modification of the present invention, the mobile communication terminal 1 may repeat the round-trip of context information a plurality of times, and expand the combination rule by ORing the context information. As a result, the mobile communication terminal 1 can acquire program related information data from a deeply related one to a shallowly related one in consideration of the user's situation. For example, instead of processing (drama & watch & sponsor) (drama & watch) + (watch & sponsor) + (drama & sponsor) + (drama & sponsor) You can search for information. In that case, as described above, there is no need to increase the number of combinations infinitely. For example, the logical product AND of adjacent context information may be used. The information may not be the pinpoint content that the user originally wanted to know, but the user can find valuable relevance from the unexpected search results obtained.

[0170] Also, as a second modification of the present invention, prior to the transmission of context information, the screen display on the mobile communication terminal 1 is temporarily changed during the transition from the state of FIG. 21 to the state of FIG. You may transition to 29 states. FIG. 29 is a diagram showing a screen display on portable communication terminal 1 when context information is transmitted by electronic mail. [0171] Further, as a third modification of the present invention, the program-related information data may be transmitted by electronic mail. FIG. 30 is a diagram showing a screen display on portable communication terminal 1 when program-related information data is received by electronic mail.

[0172] As a fourth modification of the present invention, the primary context information may include at least one of the following information. The first information is information on the history of responses to user action context information. The second information is time information for executing the search. Choices can be presented according to the choices made by the users and the choices of the history of responses to user action context information.

[0173] For example, when the user frequently selects "see" as the user action context information and "view" is included as an option of the user action context information, the mobile communication terminal 1 always displays "see". It can be presented as the first option. When information on the time to execute the search is used, the information required by the user can be searched accurately. Normally, the information service server 4 constantly updates information. Therefore, the results may be different even if the search is executed on the spot when requested and when the search is executed one day after the request is received even under the same search conditions. For this reason, if the search execution time is specified in the primary context information in Fig. 14 (or the response to the user action context in Fig. 16), different results can be obtained even in the same context. More specifically, if the user “sees” the impression of a TV program or detailed news reports about specific news using the mobile communication device 1, it will be much more beneficial to perform a search the next day. I can imagine that I can do it.

[0174] The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
