The application control code 903 defines the operation control for the target application, and one of (1) automatic start, (2) operable, (3) termination, and (4) prefetch is described. .. The application profile 904 is a value indicating the function of the television receiver required by the application, and indicates a combination of the functions that the television receiver has as an option. By referring to this value, the availability of the application is determined.

The application acquisition destination information 905 is information for specifying the acquisition destination of the application, and is location information for acquiring the HTML document to be first referred to when the application is started. Since it is assumed that the application is transmitted by broadcasting or placed on a server device on the communication network, the location information specified in the application acquisition destination information 905 also supports both broadcasting acquisition and communication acquisition. Regulations are made. The application boundary and access restriction setting 906 is information indicating the operable range as a broadcast managed application as a set of one or more areas (URL: Uniform Resource Locator). In addition, access restrictions to broadcast resources for each area are set for each function. The application boundary and access restriction setting 906 specifies 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. To do. Further, it is possible to set the access authority to a specific broadcast resource in each area within the range of the document transition.

The activation priority 907 defines which of the data broadcasting by the broadcasting service and the broadcasting managed application by the HTML document is to be started with priority when they exist at the same time. Unconditionally specify data broadcasting as the highest priority on the PMT, specify the startup priority of a specific application type on the PMT, and specify the startup priority of the target application with the startup priority 907. Shall be possible. The cache information 908 is information used for cache control when holding an application resource in preparation for reuse of an application, and describes an application version, a cache expiration date, and the like. With this information, it is possible to cache application resources that are supposed to be reused even after the application is terminated. 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 application acquisition destination or the like. The television receiver may operate to stochastically delay the application of the application control code according to the setting of this parameter.

It is possible to specify whether to start.

FIG. 7A is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when the broadcast cooperation application is specified to be started with priority. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, the main control unit 101 then acquires the PMT data string separated by the first separation unit 132. (S101), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the broadcast cooperation application is high in the processing of S101 (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 of the data string is confirmed (S104). When the application control code 903 is "automatic start" in the process of S104, the application profile 904 of the acquired AIT data string is further confirmed (S105), and the broadcast cooperation application specified in the AIT is executed. When it is confirmed that it is possible, the transmission request of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905. (S106).

The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the broadcast receiving device 100 in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S107). A known method may be used for the authentication process, and detailed description thereof will be omitted. Next, 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 based on the control of the application control unit 161. (S108).

FIG. 7B is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when it is specified to preferentially start the data broadcasting by the broadcast service. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, the main control unit 101 then acquires the PMT data string separated by the first separation unit 132. (S201), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the data broadcasting by the broadcasting service is high in the processing of S201 (S202), the data broadcasting reception processing unit 141 acquires the BML data string separated by the first separation unit 132 and obtains the BML document. Play (S203). When the automatic start of data broadcasting is set by the BML document, and when the user makes a data broadcasting start request using an operation terminal (portable information terminal 700, remote control, etc.) (S204), the 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 processing of S205 or at the same time as the processing 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). When it is confirmed in the process of S207 that the broadcast cooperation application specified in the AIT can be executed, an entry button for the executeable broadcast cooperation application is displayed on the data broadcasting screen. The entry button may be displayed at all times, 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 inactive state and the active state of the entry button may be switched.

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 the 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 of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S211).

The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the broadcast receiving device 100 in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S212). Next, 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 based on the control of the application control unit 161. (S213).

FIG. 7C is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when none of the priority activations is specified. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, the main control unit 101 then acquires the PMT data string separated by the first separation unit 132. (S301), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the broadcast cooperation application is high in the processing of S301 (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 of the data string is confirmed (S304). In the process of S304, when the application control code 903 is "startable" instead of "automatically started", the display of the broadcast program is continued without starting either the data broadcasting by the broadcasting service or the broadcasting cooperation application.

When the user makes a data broadcasting activation request using the operation terminal in the state after the processing of S304 is completed (S305), the acquisition of the BML data string and the BML are performed in the same manner as the processing after S205 in FIG. 7B. Documents are played back, data broadcasting screen information is generated, etc. (however, not shown). On the other hand, when the user requests to start the broadcast cooperation application launcher using the operation terminal after the processing of S304 is completed (S306), the application control unit 161 separates the AIT data by the first separation unit 132. The column is acquired (S307), and the application profile 904 of the acquired AIT data column is confirmed (S308). Further, the application control unit 161 displays a list of executable broadcast cooperation applications on the video display unit 173 as a broadcast cooperation application launcher (S309).

When the user selects a predetermined broadcast cooperation application from the broadcast cooperation application launcher displayed in S309 using the operation terminal (S310), the application control unit 161 selects the AIT data string separated by the first separation unit 132. Acquire (S311), and confirm 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 of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S312).

The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the broadcast receiving device 100 in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S313). Next, 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 based on the control of the application control unit 161. (S314).

In the activation sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, an example of acquiring AIT from the broadcast wave is described, but a predetermined server device specified by the information description of PMT or the like is described. You may get the AIT file from. Further, 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 the AIT indicates a broadcast wave, the HTML data string transmitted by the application control unit 161 by the data carousel method or the like and separated and output by the first separation unit 132. The HTML document may be reproduced from the above, and the reproduced HTML document (broadcasting cooperation application) may be executed by the application engine 162.

If there is no information to specify the activation priority when the data broadcasting by the broadcasting service and the broadcasting cooperation application exist on the PMT at the same time, the activation is performed only by the information such as the AIT application control code 903 and the activation priority 907. You may want to check the priority. Similarly, even if the acquisition of the information on the PMT fails, the startup priority may be confirmed only by the information such as the application control code 903 of the AIT and the startup priority 907. That is, the AIT is checked regularly regardless of the information on the PMT, and if the broadcast cooperation application specified by "automatic start" exists in the application control code 903 of the AIT, the broadcast cooperation application is used. Priority may be given to activation, and if the broadcasting cooperation application specified by "automatic activation" does not exist in the application control code 903 of AIT, priority may be given to activation of data broadcasting by the broadcasting service.

If there is no response from the service provider server 400 for a predetermined time or more when a broadcast cooperation application distribution request is made in S106, S211, or S312, a message such as "Please wait" is sent to the video display unit 173. It may be displayed. Alternatively, in this case, a message asking the user to cancel the execution of the broadcast cooperation application may be displayed.

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

[Operation sequence when linking mobile information terminals]
In the broadcast receiving device 100 of this embodiment, it is assumed that the function of the broadcasting communication cooperation service can be expanded by the cooperation operation between the broadcasting receiving device 100 and the mobile information terminal 700. For example, by installing an application (cooperation control application) prepared by the manufacturer of the television receiver, the mobile information terminal 700 can be used as a high-performance remote controller of the broadcast receiving device 100. Further, the broadcast cooperation application can be executed on the mobile information terminal 700, and for example, a service linked to the broadcast program displayed by the broadcast receiving device 100 can be displayed on the mobile information terminal 700. In order to expand the functions by the cooperative operation of the broadcast receiving device 100 and the mobile information terminal 700, it is desirable that the cooperative control application is started on the mobile information terminal 700 and operates on the mobile information terminal 700. It is assumed that the broadcast cooperation application to be operated is controlled by the cooperation control application.

FIG. 8A is an operation sequence diagram showing an example of an operation sequence when the cooperation control application is started on the mobile information terminal 700. The figure shows a series of flow (first time) until the mobile information terminal 700 performs the authentication process with the broadcast receiving device 100 and the cooperative operation becomes possible. It is assumed that the cooperation control application is installed in advance in the storage unit 710 of the mobile information terminal 700 as the cooperation control program 7002.

When the user instructs the mobile information terminal 700 to start the cooperation control application (S401), the cooperation control execution unit 7102 of the mobile information terminal 700 searches for a TV receiver capable of communicating (cooperation operation) on the network (S401). S402), the search results are displayed on the display unit 741 as a list of television receivers. If a communicable TV receiver cannot be found, a message to that effect is displayed and the process ends. When the user selects an arbitrary television receiver (broadcast receiver 100 of this embodiment) from the television receiver list, the cooperation control execution unit 7102 displays a login screen for connecting to the broadcast receiver 100 on the display unit 741. To do.

Therefore, in the following, the differences between the present embodiment and the first embodiment will be mainly described, and the common points will be omitted as much as possible in order to avoid duplication.

This embodiment is an example of the activation 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 the recording reservation of the broadcast program described with reference to FIG.

FIG. 18 is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when the broadcast cooperation application is specified to be started with priority. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, the main control unit 101 then acquires the PMT data string separated by the first separation unit 132. (S801), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the broadcast cooperation application is high in the processing of S801 (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 of the data string is confirmed (S804). When the application control code 903 is "automatic start" in the process of S804, the application profile 904 of the acquired AIT data string is further confirmed (S805), and the broadcast cooperation application specified in the AIT is executed. 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 the latest version (S806), and branch processing (S807) is performed according to the confirmed result. ..

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

In the branch processing S807, if it is not cached or if it is not the latest version (No), the predetermined service provider server 400 is used via the LAN communication unit 121 based on the information described in the application acquisition destination information 905. The distribution request of the broadcast cooperation application is transmitted to (S808).

The service provider server 400 that has received the distribution request of the broadcast cooperation application performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the broadcast receiving device 100 in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S809). A known method may be used for the authentication process, and 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 received via the LAN communication unit 121 to the RAM 104 or the storage 110 (S810), and the broadcast is performed. Set the expiration date of the cache of the linked application (S811). Next, the application engine 162 of the broadcast receiving device 100 activates the cached broadcast cooperation application based on the control of the application control unit 161 (S812).

FIG. 19 shows an example of the 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 cache expiration date of the broadcast cooperation application is set based on the expiration date information described in the cache control information 908 (S902), and the process is terminated. To do. On the other hand, when there is no cache control information 908 or the expiration date is not described in the cache control information 908, the broadcast end time of the program linked with the broadcast cooperation application is set by the broadcast cooperation application based on the EPG information. (903) is set as the expiration date of the cache of, and the process is terminated.

FIG. 20 is a diagram showing an example of a channel selection in the broadcast program and the broadcast receiving device 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 cooperation application A0 and the broadcast cooperation application B0, and the cache expiration date of the broadcast cooperation application A0 is set to the time t3 at which the program A0 ends. It is assumed that it is.

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

At time t0, when the program A0 of the channel A becomes a commercial, the channel B is selected, and the broadcast cooperation application linked to the program A0 is terminated. On the other hand, regarding the broadcast cooperation application linked to the program B0 of the channel B, writing to the cache of the broadcast cooperation application linked to the program B0 is performed from time t0 to t1 by the processing of S801 to S811 of FIG. Start the broadcast cooperation application linked to.

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

Since the program A0 ends at the time t3, the broadcast cooperation application linked to the program A0 ends. In addition, the cache of the broadcast cooperation application linked to the program A0 whose expiration date of the cache is set to the program end time t3 is cleared.

Program A1 starts at time t4, writes to the cache of the broadcast cooperation application linked to program A1 by the processing of S801 to S811 in FIG. 18 from time t4 to t5, and broadcast cooperation linked to program A1 at time t5. Launch the app.

By the above processing, for example, even if the channel is switched to another channel only during the commercial period in the middle of the program, the broadcast cooperation application linked to the program of the original channel is cached in the broadcast receiving device 100 when the channel is switched to the original channel. Therefore, it is possible to quickly start the application linked to the program of the original channel. In addition, when the program ends, the free space of the RAM 104 or the storage 110 to be used as the cache of the application linked to the next program is increased by clearing the cache of the broadcast cooperation application linked to the finished program. It is possible to cache efficiently.

Hereinafter, Example 3 of the present invention will be described. Unless otherwise specified, the configuration and effects of this example shall be the same as those of Example 2. Therefore, in the following, the differences between the present embodiment and the second embodiment will be mainly described, and the common points will be omitted as much as possible in order to avoid duplication.

In this embodiment, a case where the broadcast cooperation application is executed on both the broadcast receiving device 100 and the mobile information terminal 700 will be described.

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

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 separation unit 132 (S620), and the broadcast cooperation designated in the AIT. When it is confirmed that the application can be executed, it is confirmed whether the broadcast cooperation application is cached in the RAM 104 or the storage 110 and the latest version (S621), and branch processing is performed according to the confirmed result (S621). S622) is performed.

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

In the branch processing S622, if it is not cached or if it is not the latest version (No), the predetermined service provider server 400 is used via the LAN communication unit 121 based on the information described in the application acquisition destination information 905. (S623), the distribution request of the broadcast cooperation application is transmitted to.

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

Next, the terminal cooperation control unit 191 of the broadcast receiving device 100 acquires the broadcast cooperation application (terminal side) to be executed on the mobile information terminal 700, which is acquired from the broadcast cooperation application (television side) executed by AIT or S627. The URL information and the like are transmitted to the mobile information terminal 700 (S628). The cooperation control execution unit 7102 of the mobile 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 confirmed result. The process (S630) is performed.

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

In the branch processing S630, if it is not cached or 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).

The service provider server 400 that has received the transmission request of the broadcast cooperation application (terminal side) performs the authentication process of the mobile information terminal 700 as necessary based on the control of the application management / distribution execution unit 4103, and then applies the application. The 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 cache-writes the broadcast cooperation application distributed from the service provider server 400 received via the LAN communication unit 121 to the RAM 704 or the storage 710 (S633), and the broadcast cooperation. Set the expiration date of the cache of the application (S634). Next, the cached broadcast cooperation application (terminal side) is started (S635).

Here, the cache expiration date setting processes S626 and S634 are performed in the same manner as the cache expiration date setting process shown in FIG. In the mobile information terminal 700, to acquire the cache control information 908 and the broadcast end time information of the program, the AIT (or cache control information 908) and the EPG information are transmitted in the process S628, or the AIT file and the EPG information are predetermined. This may be done by obtaining it from the server device.

By the above processing, for example, even when switching to another channel during the commercial period in the middle of the program, the broadcast receiving device 100 and the mobile information terminal 700 are linked to the program of the original channel when switching to the original channel. Since the broadcast cooperation application is cached, it is possible to quickly start the broadcast cooperation application linked to the program of the original channel. Further, at the time when the program ends, the free space of the RAM 104 or the storage 110, the RAM 704 or the storage 710 to be used as the cache can be increased by clearing the cache of the broadcast cooperation application linked to the ended program. It is possible to cache efficiently.

In the above example, the operation sequence of the broadcast cooperation application is described when the broadcast cooperation application is specified to be started automatically with priority, but it is specified to start the data broadcasting by the broadcasting service with priority. In this case, or in the case of the broadcast cooperation application in which neither priority activation is specified, the expiration date of the cache may be set in the same manner.

Further, although the case of acquiring the broadcast cooperation application from the service provider server 400 has been described, the cache is also used in the case of acquiring and executing the broadcast cooperation application described in BML or the like from the broadcast signal as in the case of data broadcasting. You may set an expiration date.

Since it is no longer necessary to cache the broadcast cooperation application when the program corresponding to the broadcast cooperation 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 linked with the broadcast cooperation application may be set as the expiration date of the cache.

Further, in the second and third embodiments, when the program ends, the cache of the broadcast cooperation application linked to the ended program is cleared, but the RAM 104 or storage 110, RAM 704 or storage used as the cache is used. When the free space of 710 is equal to or more than a predetermined capacity, it is not necessary to clear the cache immediately at the end of the program, and the cache may be cleared at least after the program end time set as the cache expiration date. Further, when the free space of the RAM 104 or the storage 110, the RAM 704 or the storage 710 used as the cache becomes less than the predetermined capacity, the set expiration date is cleared in order from the shortest (closest to the program end time). You may try to do it. By holding the cache of the broadcast cooperation application at least until the broadcast end time of the program linked with the broadcast cooperation application, the application linked to the program of the original channel can be used even when the channel is temporarily switched due to commercial etc. It becomes possible to start up quickly.
