[Overview of application control information (AIT)]
The application control information (AIT) of this embodiment is an application ( Hereafter, it may be referred to as a broadcast cooperation application.) and is information intended to instruct its control. In addition, the broadcast cooperation application is (1) a broadcast managed system that operates only in a broadcast reception state based on a control signal such as start/end contained in a broadcast signal, and is permitted to access broadcast resources based on the control signal. applications, (2) non-broadcast managed applications that are allowed to access broadcast resources based on means such as application authentication in an operation mode in which activation/termination, etc. are not controlled by broadcast signals, and (3) broadcast resources. It may be distinguished from other general applications for which access is not permitted.

AIT transmission methods include a method of transmitting AIT in section format or XML (eXtensible Markup Language) format by broadcasting waves using a data carousel (DC) method or the like, and a method of transmitting AIT files in section format or XML format over the Internet. 200 server device using http (Hypertext Transfer Protocol) or https (Hypertext Transfer Protocol Secure). Other methods may be adopted.

FIG. 6 is a data configuration diagram showing an example of the data configuration of AIT. AIT mainly includes application type 901, application identifier 902, application control code 903, application profile 904, application acquisition source information 905, application boundary and access authority setting 906, activation priority 907, cache information 908, server access distribution parameter 909. , etc. Furthermore, other information may be included.

The application type 901 defines the application description method. In this embodiment, it is assumed that the description method of the application is HTML. The application identifier 902 is identification information composed of an organization identification for identifying a business and an application identification numbered for each business, for identifying an application unit. Note that an application unit is a set of HTML documents and their reference resources, each of which has an HTML document existing at a location specified by the application acquisition source information 905 as an entry document. The application control code 903 defines operation control for the target application, and describes one of (1) automatic activation, (2) operable, (3) termination, and (4) prefetch. . The application profile 904 is a value indicating the functions of the television receiver required by the application, and indicates a combination of functions that the television receiver has as options. Whether or not the application can be used is determined by referring to this value.

The application acquisition destination information 905 is information specifying the acquisition destination of the application, and is location information for acquiring the HTML document to be referred to first when the application is started. Since applications are assumed to be transmitted by broadcasting and stored on a server device on a communication network, the location information specified by the application acquisition destination information 905 also corresponds to both cases of acquisition by broadcasting and acquisition by communication. Regulations are made. The application boundary and access restriction setting 906 is information indicating an operable range as a broadcast managed application as a set of one or more areas (URL: Uniform Resource Locator). Also, access restrictions to broadcast resources for each area are set for each function. Application boundary and access restriction settings 906 specify the range of document transitions to prevent unexpected document transitions and access to inappropriate broadcast resources due to the chain of document transitions from the entry document when the application is started. do. In addition, it is possible to set access authority to specific broadcast resources for each area within the range of the document transition.

Activation priority 907 defines which of the data broadcast by the broadcast service and the broadcast managed application by the HTML document should be preferentially activated when they exist at the same time. unconditionally designating data broadcasting as top priority on the PMT, designating the startup priority of a specific application type on the PMT, and designating the startup priority of the target application with the startup priority 907; shall be possible. Cache information 908 is information used for cache control when holding application resources in preparation for reuse of the application, and describes the version of the application, the expiration date of the cache, and the like. With this information, it is possible to cache application resources assuming reuse even after the application ends. The server access distribution parameter 909 is a parameter set for distributing access for the purpose of reducing the load on the server where access is concentrated at the acquisition destination of the application. The television receiver may operate to stochastically delay the application of application control codes according to the setting of this parameter.

The operation of the broadcast receiving apparatus 100 of this embodiment will be described below.

[Operation sequence at application startup]
First, the process of activating the broadcast cooperation application based on the AIT transmitted by the broadcast wave in the broadcast receiving apparatus 100 of the present embodiment will be described. In the broadcast receiving apparatus 100 of the present embodiment, when the data broadcast by the broadcast service and the broadcast cooperation application exist at the same time, which one is prioritized based on the information on the PMT, the application control code 903 of the AIT, the activation priority 907, and the like. It is possible to specify whether to start with

FIG. 7A is an operation sequence diagram showing an example of the operation sequence of the broadcast-linked application when it is specified that the broadcast-linked application should be preferentially activated. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, the main controller 101 then acquires the PMT data string separated by the first separator 132. (S101), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S101 that the activation priority of the broadcast-linked application is high (S102), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S103), and the acquired AIT The application control code 903 in the data string is confirmed (S104). In the process of S104, if the application control code 903 is "automatic start", furthermore, the application profile 904 of the acquired AIT data string is confirmed (S105), and execution of the broadcast cooperation application specified in the AIT is confirmed. When it is confirmed that it is possible, based on the information described in the application acquisition destination information 905, a transmission request for the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121. (S106).

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S107). Note that a known method may be used for the authentication process, and a detailed description thereof will be omitted. Next, under the control of the application control unit 161, the application engine 162 of the broadcast receiving device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121. (S108).

FIG. 7B is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when it is specified that the data broadcast by the broadcast service should be preferentially activated. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, the main controller 101 then acquires the PMT data string separated by the first separator 132. (S201), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S201 that the data broadcast by the broadcast service has a high activation priority (S202), the data broadcast reception processing unit 141 acquires the BML data string separated by the first separation unit 132 and converts it into a BML document. Play back (S203). When automatic activation of data broadcasting is set by the BML document, and when the user requests activation of data broadcasting using an operation terminal (portable information terminal 700, remote controller, etc.) (S204), data broadcasting engine 142 generates data broadcasting screen information by executing the reproduced BML document, and displays it on the video display unit 173 (S205).

After the process of S205 or simultaneously with the process of S205, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S206), and confirms the application profile 904 of the acquired AIT data string. (S207). In the process of S207, when it is confirmed that the broadcast-linked application specified by the AIT can be executed, an entry button to the executable broadcast-linked application is displayed on the data broadcasting screen. The entry button may always be displayed, and the color scheme may be changed from the inactive color to the active color only when the broadcast cooperation application can be executed. By changing the shape, the entry button may be switched between an inactive state and an active state.

When the user selects the entry button using the operation terminal (S208), the data broadcasting engine 142 ends the process of executing the BML document and generating data broadcasting screen information (S209). Subsequently, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S210), and confirms the application acquisition destination information 905 of the acquired AIT data string. Further, based on the information described in the application acquisition destination information 905 confirmed in S210, a transmission request for the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S211).

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S212). Next, under the control of the application control unit 161, the application engine 162 of the broadcast receiving device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121. (S213).

FIG. 7C is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when no priority activation is specified. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, the main controller 101 then acquires the PMT data string separated by the first separator 132. (S301), the startup priority described in the PMT is confirmed. When it is confirmed in the process of S301 that the broadcast-linked application has a high activation priority (S302), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S303), and the acquired AIT The application control code 903 in the data string is confirmed (S304). In the process of S304, if the application control code 903 is "startable" instead of "automatic start", the display of the broadcast program is continued without starting neither the data broadcasting by the broadcasting service nor the broadcast cooperation application.

When the user uses the operation terminal to make a request to start data broadcasting after the process of S304 (S305), the BML data string is acquired and the BML Reproduction of documents, generation of data broadcasting screen information, etc. are performed (not shown). On the other hand, when the user uses the operation terminal to request activation of the broadcast-linked application launcher after the processing of S304 is completed (S306), the application control unit 161 separates the AIT data separated by the first separation unit 132. A string is obtained (S307), and the application profile 904 of the obtained AIT data string is confirmed (S308). Furthermore, the application control unit 161 displays a list of executable broadcast-linked applications as a broadcast-linked application launcher on the video display unit 173 (S309).

When the user selects a predetermined broadcast-linked application from the broadcast-linked application launcher displayed in S309 using the operation terminal (S310), the application control unit 161 separates the AIT data string separated by the first separation unit 132 into (S311), and confirms the application acquisition destination information 905 of the acquired AIT data string. Further, based on the information described in the application acquisition destination information 905 confirmed in S311, a transmission request for the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S312).

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S313). Next, under the control of the application control unit 161, the application engine 162 of the broadcast receiving device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121. (S314).

In addition, in the activation sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, an example of acquiring AIT from broadcast waves is described. Alternatively, the AIT file may be acquired from. Also, the acquisition of the broadcast cooperation application may be performed not from the server device (service provider server 400) on the network but from the broadcast wave. That is, when the location information described in the application acquisition destination information 905 of AIT indicates a broadcast wave, the application control unit 161 transmits the HTML data string by the data carousel method or the like and is separated and output by the first separating unit 132. , and the application engine 162 executes the reproduced HTML document (broadcast-linked application).

It should be noted that if there is no information specifying the activation priority when the data broadcast by the broadcasting service and the broadcast cooperation application exist simultaneously on the PMT, the activation is performed only by information such as the application control code 903 and the activation priority 907 of the AIT. You may make it confirm a priority. Similarly, even if the acquisition of the information on the PMT fails, the activation priority may be confirmed only by information such as the application control code 903 of the AIT and the activation priority 907 . That is, regardless of the information on the PMT, the AIT is periodically checked, and if there is a broadcast-linked application specified by "automatic start" in the application control code 903 of the AIT, the broadcast-linked application Activation is prioritized, and if there is no broadcast-linked application designated by "automatic activation" in the application control code 903 of the AIT, activation of data broadcasting by the broadcasting service may be prioritized.

Further, when there is no response from the service provider server 400 for a predetermined period of time or more when the distribution request for the broadcast cooperation application is made in S106, S211, or S312, a message such as "Please wait for a while" is displayed on the video display unit 173. You may make it display. Alternatively, in this case, a message may be displayed asking the user to stop executing the broadcast cooperation application.

Further, the activation sequence of the broadcast cooperation application is not limited to the three patterns described above, and it goes without saying that the activation sequence may be different.

[Operational sequence when linking mobile information terminals]
In the broadcast receiving device 100 of the present embodiment, it is assumed that the functions of the broadcast communication cooperation service can be expanded by cooperative operation between the broadcast receiving device 100 and the mobile information terminal 700 .

Also, the broadcast cooperation application can be executed on the portable information terminal 700, and for example, a service linked to the broadcast program being displayed on the broadcast receiving device 100 can be displayed on the portable information terminal 700 as well. It should be noted that in order to extend the functions by cooperative operation between the broadcast receiving apparatus 100 and the mobile information terminal 700, it is desirable that the cooperation control application is activated on the mobile information terminal 700, and the operation on the mobile information terminal 700 is performed. It is assumed that the broadcast cooperation application to operate is controlled by the cooperation control application.

This figure shows a series of flows (first time) from when the portable information terminal 700 performs authentication processing with the broadcast receiving apparatus 100 to when the cooperative operation becomes possible. It is assumed that the cooperative control application is installed in the storage unit 710 of the mobile information terminal 700 in advance as the cooperative control program 7002 .

When the user instructs the activation of the cooperative control application on the portable information terminal 700 (S401), the cooperative control execution unit 7102 of the portable information terminal 700 searches for a television receiver capable of communication (cooperative operation) on the network ( S402), the search result is displayed on the display unit 741 as a television receiver list. If a communicable television receiver cannot be found, a message to that effect is displayed and the process ends. When the user selects an arbitrary television receiver (broadcast receiving device 100 of this embodiment) from the television receiver list, the cooperation control execution unit 7102 displays a login screen for connecting to the broadcast receiving device 100 on the display unit 741. do. When the user inputs authentication information (login name and password specified by the broadcast receiving apparatus 100, etc.) to the login screen via the operation unit 730 (S403), the cooperation control execution unit 7102 receives the input authentication information. is stored in the authentication information storage area 7012 and simultaneously transmitted to the broadcast receiving apparatus 100 (S404). The process of transmitting the authentication information to the broadcast receiving device 100 may be performed via the LAN communication unit 721 and the router device 210, or may be performed directly to the broadcast receiving device 100 via the NFC communication unit 723. .

Terminal cooperation control section 191 of broadcast receiving apparatus 100 that has received the authentication information via LAN communication section 121 refers to authentication information storage area 1012 to check whether the received authentication information is correct. (S405). When the received authentication information is confirmed to be correct by the process of S405, the information of the mobile information terminal 700 is stored in the authentication information storage area 1012, and the mobile information terminal 700 is authenticated (S406). The portable information terminal 700 that has obtained the authentication of the broadcast receiving apparatus 100 displays the basic screen of the cooperative control application (for example, the advanced remote control screen) on the display unit 741 (S407).

[EPG screen of broadcast receiving device]
FIG. 16A is a screen display diagram showing an example of an electronic program guide (EPG) display screen in the broadcast receiving apparatus 100 of this embodiment. The EPG display screen 173e is a distribution schedule of broadcast programs in the digital broadcasting service of this embodiment, which is created by the main control unit 101 based on the program information data string output from the first separation unit 132. FIG. It is assumed that the EPG display screen 173e is displayed on the video display unit 173 by selecting the program guide key 741a7 on the basic screen 741a of the cooperative control application.

In this embodiment, the EPG display screen 173e is in a matrix form with the vertical axis representing time and the horizontal axis representing service IDs (channels). indicate. Detailed information 173e1 of each broadcast program is mainly composed of a title area 173e2 and a detailed description area 173e3, as shown in FIG. 16A.

The title area 173e2 displays the program title of each broadcast program, symbols representing attributes of each broadcast program, and the like. The symbols and the like representing the attributes of each broadcast program are, for example, a symbol that symbolizes "New" that means that it is a new program, a symbol that symbolizes "Replay" that means that it is a rebroadcast program, etc. Alternatively, a mark or the like that symbolizes "data", which means that data broadcasting by a broadcasting service is supported, may be used. Further, in the case of a broadcast program for which a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 of the present embodiment is prepared, a mark or the like that symbolizes "Linkage" to that effect may be used. The detailed explanation area 173e3 displays related information such as the contents of each broadcast program, the performers, the URL of the homepage introducing each broadcast program, and the like.

It should be noted that even if a broadcast cooperation application is prepared for the broadcast program, the mark or the like symbolizing the "Linkage" displayed in the title area 173e2 is displayed on the information display device as a result of checking the application profile 904. If execution by 100 is not possible, it may not be displayed. In addition, the mark symbolized by "Linkage", which is displayed in the title area 173e2 and indicates that the broadcast program is prepared with the executable broadcast-linked application, furthermore, the linked operation with the portable terminal device is possible. The color, shape, font, etc. may be changed depending on whether or not it is. If the linked operation with the portable terminal device is possible, the symbol symbolized "Mobile" may be displayed together with the symbol symbolized "Linkage".

The presence or absence of the mark symbolizing "Linkage" and the symbol symbolizing "Mobile" is indicated in advance in the EIT information including detailed information of each broadcast program. Whether or not the broadcast program has a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 of the embodiment, whether or not the executable broadcast cooperation application can perform cooperative operation with a mobile terminal device, It may be controlled by acquiring information such as. Alternatively, the information obtained from the program distribution information of the digital broadcast programs prepared in a predetermined server device on the Internet 200 is stored in an electronic program guide created based on the program information data string obtained from the broadcast waves of the digital broadcast service. You may make it add.

As described above, on the EPG display screen 173e, there is a symbolic mark of "Linkage" indicating that the broadcast program is prepared with an executable broadcast-linked application, and that linkage operation with a mobile terminal device is possible. By displaying the symbolized mark of "Mobile" indicating , the user can easily grasp the correspondence status of each broadcast program in the broadcast receiving apparatus 100 to the broadcast-communication cooperation service. Needless to say, the marks obtained by symbolizing the predetermined characters representing the attributes of each broadcast program may be replaced with the characters themselves, sentences, or the like. By changing the background color of the detailed information 173e1 of each broadcast program, the correspondence status of each broadcast program to the broadcast-communication cooperation service may be indicated. In addition, the symbolized mark of "Linkage" and the symbolized mark of "Mobile" are not usually displayed in the title area 173e2. It may be made to be displayed.

The broadcast receiving apparatus 100 of this embodiment has a function of making viewing reservation and/or recording reservation for each broadcast program from the EPG display screen 173e. For example, while the EPG display screen 173e is displayed, the cursor key 741ac on the basic screen 741a of the cooperative control application is used to move the program selection cursor 173e4 on the EPG display screen 173e, and the enter key 741ad selects an arbitrary broadcast program. is selected, reservation for viewing and/or recording of the selected broadcast program is made.

In the above-described process, if the broadcast program for which the viewing reservation and/or the recording reservation has been made is a broadcast program corresponding to the broadcast and communication cooperation service, the broadcasting is triggered by the viewing reservation and/or the recording reservation. Acquisition of the broadcast cooperation application prepared for the broadcast program may be started without waiting for the broadcast start time of the program. That is, information (location information such as URL) designating the acquisition destination of the broadcast cooperation application is described in the EIT information including detailed information of each broadcast program. In this way, the broadcast receiving device 100 can grasp the information of the acquisition destination of the broadcast cooperation application prepared for each broadcast program at the time when the broadcast program is selected with the program selection cursor 173e4. Become. Therefore, the broadcast receiving apparatus 100 can start acquiring the broadcast cooperation application before the broadcast start time of the broadcast program.

In addition, if the broadcast program for which the viewing reservation and/or recording reservation has been made is a broadcast program compatible with the broadcast and communication cooperation service and is a broadcast program that can be operated in cooperation with the mobile terminal device, The broadcast cooperation application (terminal side) provided in the above may also start acquiring before the broadcast start time of the broadcast program by the same processing as described above.

It should be noted that the configuration and effects of this embodiment are the same as those of the first embodiment unless otherwise specified. Therefore, the differences between the present embodiment and the first embodiment will be mainly described below, and descriptions of common points will be omitted as much as possible to avoid duplication.

The present embodiment is an example of the start sequence of the broadcast cooperation application corresponding to the case where the broadcast cooperation application is cached in advance due to the viewing reservation and/or recording reservation of the broadcast program described in FIG. 17 .

FIG. 18 is an operation sequence diagram showing an example of the operation sequence of the broadcast-linked application when it is specified that the broadcast-linked application should be preferentially activated. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, the main controller 101 then acquires the PMT data string separated by the first separator 132. (S801), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S801 that the broadcast-linked application has a high activation priority (S802), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S803), and the acquired AIT The application control code 903 in the data string is confirmed (S804). In the process of S804, if the application control code 903 is "automatic start", furthermore, the application profile 904 of the acquired AIT data string is confirmed (S805), and execution of the broadcast cooperation application specified in the AIT is confirmed. When it is confirmed that it is possible, it is confirmed whether the broadcast cooperation application is cached in the RAM 104 or the storage 110 and whether it is the latest version (S806), and branch processing is performed (S807) according to the confirmation result. .

In the branch processing S807, if the broadcast cooperation application is cached and is the latest version (Yes), the broadcast cooperation application is activated (S812).

In the branch processing S807, if it is not cached or if it is not the latest version (No), based on the information described in the application acquisition source information 905, via the LAN communication unit 121, the predetermined service provider server 400 (S808).

Note that a known method may be used for the authentication process, and a detailed description thereof will be omitted. Subsequently, the application control unit 161 cache-writes the predetermined broadcast cooperation application distributed from the service provider server 400, which is received via the LAN communication unit 121, in the RAM 104 or the storage 110 (S810). The expiration date of the cooperative application cache is set (S811). Next, the application engine 162 of the broadcast receiving device 100 activates the cached broadcast cooperation application under the control of the application control unit 161 (S812).

FIG. 19 shows an example of a flowchart of the cache expiration date setting process S811.

In FIG. 19, first, the cache control information 908 of the application control information AIT is confirmed, and branch processing is performed (S901). When the expiration date is described in the cache control information 908, the expiration date of the cache of the broadcast cooperation application is set based on the expiration date information described in the cache control information 908 (S902), and the process ends. do. On the other hand, if there is no cache control information 908 or if the expiration date is not described in the cache control information 908, based on the EPG information, the broadcast end time of the program with which the broadcast cooperation application is linked is determined by the broadcast cooperation application. is set as the expiration date of the cache (903), and the process ends.

FIG. 20 is a diagram showing an example of a broadcast program, channel selection in the broadcast receiving apparatus 100, a cache of the broadcast cooperation application, and an execution state of the broadcast cooperation application. Here, the cache control information 908 is not described in the application control information AIT of the broadcast-linked application A0 and the broadcast-linked application B0, and the expiration date of the cache of the broadcast-linked application A0 is set to the time t3 when the program A0 ends. shall be

In FIG. 20, channel A is selected until time t0, and broadcast cooperation application A0 linked to program A0 is being executed.

At time t0, when program A0 on channel A becomes a commercial, channel B is selected, and the broadcast cooperation application linked to program A0 is terminated. On the other hand, for the broadcast cooperation application that cooperates with program B0 on channel B, the cache of the broadcast cooperation application that cooperates with program B0 is written from time t0 to time t1 by the processing of S801 to S811 in FIG. Start the broadcast cooperation application linked to .

At time t2, channel A is selected when program B0 on channel B becomes a commercial, and the broadcast cooperation application linked to program B0 is terminated. On the other hand, for the application linked to program A0 on channel A, the processes from S801 to S812 in FIG. 18 are performed to execute the application linked to program A0.

At time t3, since program A0 ends, the broadcast cooperation application linked to program A0 is ended. Also, the cache of the broadcast cooperation application linked to the program A0 whose cache expiration date is set to the program end time t3 is cleared.

At time t4, program A1 starts, and from time t4 to t5, the processing of S801 to S811 in FIG. Launch the app.

With the above processing, for example, even when switching to another channel only during a commercial period in the middle of a program, when switching to the original channel, the broadcast cooperation application linked to the program of the original channel is cached in the broadcast receiving device 100. Therefore, it is possible to quickly start the application linked to the program of the original channel. Also, at the end of the program, clearing the cache of the broadcast-linked application linked to the ended program increases the free space of the RAM 104 or the storage 110 for use as the cache of the application linked to the next program. can be used, and caching can be performed efficiently.

A third embodiment of the present invention will be described below. It should be noted that the configuration and effects of this embodiment are the same as those of the second embodiment unless otherwise specified. Therefore, the differences between the present embodiment and the second embodiment will be mainly described below, and descriptions of common points will be omitted as much as possible to avoid duplication.

In this embodiment, a case will be described in which the broadcast cooperation application is executed in both the broadcast receiving apparatus 100 and the mobile information terminal 700. FIG.

FIG. 21 is an operation sequence diagram showing an example of the activation sequence of the broadcast cooperation application of the broadcast receiving apparatus 100 and the mobile information terminal 700. As shown in FIG.

That is, after the processing of S601 to S611 in FIG. 8C, the application control unit 161 of the broadcast receiving device 100 acquires the AIT data string separated by the first separating unit 132 (S620), When it is confirmed that the application can be executed, it is confirmed whether the broadcast-linked application is cached in the RAM 104 or the storage 110 and whether it is the latest version (S621), and branch processing ( S622) is performed.

In the branch processing S622, if the broadcast cooperation application is cached and is the latest version (Yes), the broadcast cooperation application is activated (S627).

In the branch processing S622, if it is not cached or if it is not the latest version (No), based on the information described in the application acquisition source information 905, via the LAN communication unit 121, the predetermined service provider server 400 (S623).

Service provider server 400 that has received the distribution request for the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, to application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S624). Note that a known method may be used for the authentication process, and a detailed description thereof will be omitted. Subsequently, the application control unit 161 caches the broadcast-linked application distributed from the service provider server 400 via the LAN communication unit 121 to the RAM 104 or the storage 110 (S625). The expiration date of the cache is set (S626). Next, the application engine 162 of the broadcast receiving device 100 activates the cached broadcast-linked application under the control of the application control unit 161 (S627).

Next, the terminal cooperation control unit 191 of the broadcast receiving apparatus 100 acquires the broadcast cooperation application (terminal side) to be executed on the mobile information terminal 700, which is acquired from the AIT or the broadcast cooperation application (TV side) executed in S627. URL information and the like are transmitted to the portable information terminal 700 (S628). The cooperation control execution unit 7102 of the portable information terminal 700 confirms whether the broadcast cooperation application (terminal side) is cached in the RAM 704 or the storage 710 and is the latest version (S629), and branches according to the confirmation result. Processing (S630) is performed.

In the branch processing S630, if the broadcast cooperation application is cached and is the latest version (Yes), the broadcast cooperation application (terminal side) is activated (S635).

In the branching process S630, if it is not cached or if it is not the latest version (No), LAN communication is performed based on the acquisition destination URL information of the broadcast cooperation application (terminal side) received via the LAN communication unit 721. A transmission request for the broadcast cooperation application (terminal side) is transmitted to the predetermined service provider server 400 via the unit 721 (S631).

Service provider server 400, which has received the transmission request of the broadcast cooperation application (terminal side), performs authentication processing of portable information terminal 700 as necessary based on the control of application management/distribution execution unit 4103, and then performs application A predetermined broadcast cooperation application (terminal side) stored in the storage area 4013 is distributed via the LAN communication unit 421 (S632). The HTML browser engine 7103 of the mobile information terminal 700 caches the broadcast cooperation application distributed from the service provider server 400 received via the LAN communication unit 121 in the RAM 704 or the storage 710 (S633), and the broadcast cooperation The application cache expiration date is set (S634). Next, the cached broadcast cooperation application (terminal side) is activated (S635).

Here, the cache expiration date setting processing S626 and S634 are performed in the same manner as the cache expiration date setting processing shown in FIG. In the portable information terminal 700, acquisition of the cache control information 908 and program broadcast end time information is performed by transmitting the AIT (or the cache control information 908) and EPG information in step S628, or transmitting the AIT file and EPG information to a predetermined You may perform by acquiring from a server apparatus.

With the above processing, for example, even when switching to another channel only during a commercial period in the middle of a program, when switching to the original channel, the broadcast receiving apparatus 100 and the portable information terminal 700 are linked to the program of the original channel. Since the broadcast cooperation application is cached, it is possible to quickly activate the broadcast cooperation application in cooperation with the program of the original channel. In addition, at the time when the program ends, by clearing the cache of the broadcast cooperation application linked to the ended program, it is possible to increase the free space of the RAM 104 or the storage 110 and the RAM 704 or the storage 710 for use as a cache next time. This allows for efficient caching.

In the above example, the operation sequence of the broadcast-linked application has been described when it is specified that the broadcast-linked application is preferentially automatically started. A cache expiration date may also be similarly set for a broadcast-linked application in which no preferential activation is specified.

Also, the case where the broadcast-linked application is acquired from the service provider server 400 has been described, but even in the case of acquiring and executing the broadcast-linked application described in BML or the like from the broadcast signal as in data broadcasting, the cache is similarly stored. An expiration date may be set.

In addition, since there is no need to cache the broadcast-linked application when the program corresponding to the broadcast-linked application ends, even if there is cache control information in the cache expiration date setting process S811 shown in FIG. Based on the EPG information, the broadcast end time of the program with which the broadcast collaboration application is linked may be set as the expiration date of the cache.

In addition, in the second and third embodiments, when the program ends, the cache of the broadcast cooperation application linked to the ended program is cleared. If the free space in 710 is equal to or greater than a predetermined capacity, it is not necessary to clear the cache immediately after the program ends, and the cache may be cleared at least after the program end time set as the cache validity period. Furthermore, when the free space of the RAM 104 or the storage 110, the RAM 704 or the storage 710 used as a cache becomes less than a predetermined capacity, clearing is performed in ascending order of the set expiration date (program ending time is near). You may make it By retaining the cache of the broadcast collaboration application at least until the broadcast end time of the program that the broadcast collaboration application is linked to, even if the channel is temporarily switched due to commercials etc., the application linked to the program of the original channel It is possible to start up quickly.
