[Overview of application control information (AIT)]
The application control information (AIT) of the present embodiment is an application (in this embodiment, the broadcast receiving apparatus 100) that cooperates with the broadcast service in the broadcast communication cooperation function supported by the broadcast receiving apparatus 100 (in the present embodiment, the broadcast receiving apparatus 100). Hereinafter, it may be referred to as a broadcast cooperation application.) It is assumed that the information is intended to inform the existence of the application and to instruct its control. The broadcast cooperative application operates only in a broadcast reception state based on a control signal such as activation / termination included in a broadcast signal, and the broadcast managed app is permitted to access a broadcast resource based on the control signal. An application, (2) a non-broadcast managed application in which access to the broadcast resource is permitted based on means such as application authentication in an operation mode in which activation / termination is not controlled by the broadcast signal, and (3) broadcast resource It can be distinguished from other general applications where access is not permitted.

An L-format AIT file is transferred from a server device on the Internet 200 to http (Hype
rtext Transfer Protocol) or https (Hyperte)
Any of the distribution methods using xt Transfer Protocol Secure) may be used. Other methods may be adopted.

FIG. 6 is a data configuration diagram showing an example of the data configuration of the AIT. AIT is mainly
Application type 901, application identifier 902, application control code 903, application profile 904, application acquisition destination information 90
5, application boundary / access authority setting 906, activation priority 907, cache information 908, server access distribution parameter 909, and the like. Furthermore, other information may be included.

The application type 901 defines the application description method. In this embodiment, it is assumed that the application description method is HTML. The application identifier 902 is identification information composed of an organization identification for identifying a business operator and an application identification numbered for each business operator for identifying an application unit. Note that an application unit is a set of HTML documents and their reference resources that use an HTML document existing at a location specified by the application acquisition destination information 905 as an entry document. The application control code 903 defines operation control for the target application, and is (1) automatic start, (2) operable, (3) end,
(4) One of the prefetches is described. Application profile 904
Is a value indicating the function of the television receiver requested by the application, and is a combination of functions that the television receiver has as an option. Whether or not the application can be used is determined by referring to this value.

The application acquisition destination information 905 is information for specifying an application acquisition destination, and is location information for acquiring an HTML document that is referred to first when the application is started. Since the application is assumed to be transmitted by broadcast or placed on a server device on a communication network, the location information specified by the application acquisition destination information 905 is also compatible with both broadcast acquisition and communication acquisition. Regulations are made. The application boundary and access restriction setting 906 has an operable range as a broadcast managed application in one or more areas (URL: Uniform Resource).
This is information shown as a set of (Locator). Moreover, the access restriction to the broadcast resource for each area is set for each functional unit. Application boundary and access restriction setting 90
6 specifies a range of document transition for preventing transition to an unexpected document due to a chain of document transitions from an entry document at the time of application activation, access to inappropriate broadcast resources, and the like. In addition, it is possible to set an access right to a specific broadcast resource in units of areas within the document transition range.

The activation priority 907 specifies which one is to be activated preferentially when there is a data broadcast by a broadcast service and a broadcast managed application by an HTML document at the same time. Unconditionally designating data broadcasting as the highest priority on the PMT, designating the priority of activation of a specific application type on the PMT, and designating the activation priority of the target application as the activation priority 907; Is possible. The cache information 908 is information used for cache control when an application resource is held in preparation for application reuse. With this information, application resources can be cached assuming reuse 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 a server on which access is concentrated at an application acquisition destination or the like. The television receiver may operate to stochastically delay application of the application control code according to the setting of this parameter.

  Below, operation | movement of the broadcast receiving apparatus 100 of a present Example is demonstrated.

The application control unit 161 acquires the AIT data sequence separated by the first separation unit 132 (S103), and confirms the application control code 903 of the acquired AIT data sequence (S104). In the process of S104, if the application control code 903 is “automatic start”, the application profile 904 of the acquired AIT data string is further confirmed (S105), and the execution of the broadcast cooperation application specified in the AIT is performed. When it is confirmed that it is possible, a transmission request for the broadcast cooperative app is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition source information 905. (S106).

The service provider server 400 that has received the transmission request for the broadcast cooperative application performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores it in the application storage area 4013. Distribution of the predetermined broadcast cooperation application memorize | stored is performed via the LAN communication part 421 (S107). Note that a known method may be used for the authentication process, and detailed description thereof is omitted. Next, the application engine 162 of the broadcast receiving device 100 is controlled based on the control of the application control unit 161.

(S202), the data broadcast reception processing unit 141 acquires the BML data string separated by the first separation unit 132 and reproduces the BML document (S203). When automatic activation of data broadcasting is set by the BML document, and when the user makes a data broadcasting activation request using an operation terminal (such as the portable information terminal 700 or a remote controller) (S204), the data broadcasting engine 14
2 generates data broadcast 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 acquires the obtained AIT
The application profile 904 of the IT data string is confirmed (S207). S207
When it is confirmed that the broadcast cooperative app specified in the AIT can be executed in the process, an entry button for the executable broadcast cooperative app is displayed on the data broadcast 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. The entry button may be switched between an inactive state and an active state by changing the shape.

When the user selects the entry button using the operation terminal (S208), the data broadcast engine 142 ends the process of executing the BML document and generating the data broadcast 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 broadcast cooperation application transmission request 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 for the broadcast cooperative application performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores it in the application storage area 4013. Distribution of the predetermined broadcast cooperation application memorize | stored is performed via the LAN communication part 421 (S212). Next, the broadcast receiving apparatus 10
Based on the control of the application control unit 161, the 0 application engine 162 activates the predetermined broadcast cooperative app received from the service provider server 400 received via the LAN communication unit 121 (S213).

FIG. 7C is an operation sequence diagram illustrating an example of an operation sequence of the broadcast cooperative app when none of the priority activations is defined. The figure shows that the broadcast receiving apparatus 100 is operated by PMT and AIT.
This shows a series of flow from confirming as appropriate to starting a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing of a channel desired by the user and acquires a TS, next, the PM separated by the first separation unit 132 by the main control unit 101
The T data string is acquired (S301), and the activation priority described in the PMT is confirmed. S3
In the process 01, it is confirmed that the activation priority of the broadcast cooperative application is high (S302).
The application control unit 161 acquires the AIT data sequence separated by the first separation unit 132 (S303), and confirms the application control code 903 of the acquired AIT data sequence (S304). In the process of S304, when the application control code 903 is “startable” instead of “automatic start”, the display of the broadcast program is continued without starting either the data broadcast by the broadcast service or the broadcast cooperative application.

When the user makes a data broadcast activation request using the operation terminal in the state after finishing the process of S304 (S305), the acquisition of the BML data string and the BML are performed as in the processes after S205 of FIG. 7B. Document reproduction, data broadcast screen information generation, etc. are performed (however, illustration is omitted)
. On the other hand, when the user makes a launch request for the broadcast cooperative app launcher using the operation terminal in the state after finishing the processing of S304 (S306), the AIT data separated by the first separation unit 132 by the application control unit 161 A 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 cooperative apps on the video display unit 173 as a broadcast cooperative app launcher (S309).

When the user selects a predetermined broadcast cooperative app from the broadcast cooperative app launcher displayed in S309 using the operation terminal (S310), the application control unit 161 displays 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 for the broadcast cooperative app is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S31).
2).

The service provider server 400 that has received the transmission request for the broadcast cooperative application performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores it in the application storage area 4013. Distribution of the predetermined broadcast cooperation application memorize | stored is performed via the LAN communication part 421 (S313). Next, the broadcast receiving apparatus 10
Based on the control of the application control unit 161, the 0 application engine 162 activates the predetermined broadcast cooperation app distributed from the service provider server 400 received via the LAN communication unit 121 (S314).

7A to 7C, the example of acquiring the AIT from the broadcast wave has been described in each of the broadcast cooperative app activation sequences. However, a predetermined server device designated by the information description of the PMT or the like is described. The AIT file may be acquired from the AIT file. Also, the acquisition of the broadcast cooperation application is not performed from the server device (service provider server 400) on the network,
You may go 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 sequence 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 HTML document is reproduced from the application, and the application engine 162 executes the reproduced HTML document (broadcast cooperation application).

If there is no information for specifying the activation priority when there is a data broadcast by the broadcast service and a broadcast cooperative application at the same time on the PMT, the AIT application control code 90
3 and the activation priority 907 may be used to confirm the activation priority.
Similarly, when the acquisition of the information on the PMT fails, the activation priority may be confirmed only by information such as the AIT application control code 903 and the activation priority 907. In other words, the AIT is periodically checked regardless of the information on the PMT, and when there is a broadcast cooperative application specified by “automatic activation” in the application control code 903 of the AIT, the broadcast cooperative application Priority is given to activation, and AIT application control code 90
If there is no broadcast cooperation application designated by “automatic activation” in FIG. 3, priority may be given to activation of data broadcasting by the broadcasting service.

In addition, if a response from the service provider server 400 is not received 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 displayed on the video display unit 173. It may be displayed. Alternatively, in this case, a message for inquiring the user to cancel the execution of the broadcast cooperative app may be displayed.

In addition, the launch sequence of the broadcast cooperation application is not limited to the above three patterns,
Needless to say, it may be activated by a different sequence.

[Operation sequence when linking portable information terminals]
In the broadcast receiving apparatus 100 according to the present embodiment, it is assumed that the function of the broadcast communication cooperation service can be expanded by the cooperative operation between the broadcast receiving apparatus 100 and the portable information terminal 700.

As shown in FIG. 16A, the detailed information 173e1 of each broadcast program mainly includes a title area 173e2 and a detailed description area 173e3.

In the title area 173e2, a program title of each broadcast program, a symbol representing the attribute of each broadcast program, and the like are displayed. The symbols or the like indicating the attributes of each broadcast program are, for example, a sign obtained by symbolizing “New” indicating a new program, or “Replay” indicating a re-broadcast program.
, Etc., as a symbol. Alternatively, it may be a mark or the like that symbolizes “data” meaning that it corresponds to data broadcasting by a broadcasting service. Also, the broadcast receiving apparatus 1 of the present embodiment
In the case of a broadcast program for which a broadcast cooperation application that can be executed at 00 is prepared, a symbol or the like that is a symbol of “Linkage” indicating that may be used. The detailed explanation area 173e3 displays related information such as the program contents and performers of each broadcast program, the URL of a homepage introducing each broadcast program, and the like.

Note that the symbol or the like symbolized “Linkage” displayed in the title area 173e2 indicates that the information display device is the result of the confirmation of the application profile 904 even when a broadcast cooperation application is prepared for the broadcast program. If execution at 100 is not possible, it may not be displayed. In addition, the mark that is displayed in the title area 173e2 and symbolizes “Linkage” indicating that it is a broadcast program for which the executable broadcast cooperation application is prepared can be further linked with a mobile terminal device. The color, shape, font,
Etc. may be changed. When cooperative operation with a mobile terminal device is possible, the “Linkag”
A mark symbolizing “Mobile” may be displayed together with a mark symbolizing “e”.

The presence / absence of display of the symbol “Linkage” or the symbol “Mobile” is described in advance in EIT information including detailed information of each broadcast program. Whether or not the broadcast cooperative app that can be executed by the broadcast receiving apparatus 100 according to the embodiment is a broadcast program, whether or not the executable broadcast cooperative app can perform a cooperative operation with the mobile terminal device, It may be controlled by acquiring such information. Alternatively, the information acquired from the program distribution information of the digital broadcast program prepared in a predetermined server device on the Internet 200 is converted into an electronic program guide created based on the program information data string acquired from the broadcast wave of the digital broadcast service. You may make it add.

As described above, on the EPG display screen 173e, it is possible to perform a cooperative operation with a sign symbolizing “Linkage” indicating that it is a broadcast program for which an executable broadcast cooperative application is prepared and a portable terminal device. By displaying a mark symbolizing “Mobile” indicating the “mobile”, the user can easily grasp the corresponding status of each broadcast program to the broadcast communication cooperation service in the broadcast receiving apparatus 100. Needless to say, a mark obtained by symbolizing a predetermined character representing the attribute of each broadcast program may be replaced with the character itself or a sentence. By changing the background color of the detailed information 173e1 of each broadcast program, the corresponding status of the broadcast program to the broadcast communication cooperation service may be indicated. In addition, the “Linkage” symbolized “Mobil”
The mark or the like symbolized with “e” is not normally displayed in the title area 173e2, but may be displayed in a pop-up only when each broadcast program is selected by the program selection cursor 173e4.

The broadcast receiving apparatus 100 according to the present embodiment has a function of performing viewing reservation and / or recording reservation for each broadcast program from the EPG display screen 173e. For example, when the EPG display screen 173e is displayed, the cursor key 741ac on the basic screen 741a of the cooperation control application is used to execute E
The program selection cursor 173e4 on the PG display screen 173e is moved, and the enter key 741ad
By selecting an arbitrary broadcast program, the viewing reservation and / or recording reservation of the selected broadcast program is performed.

In the above-described processing, when the broadcast program for which the viewing reservation and / or recording reservation has been made is a broadcast program corresponding to a broadcasting / communication cooperation service, the broadcast is triggered by the viewing reservation and / or recording reservation being made. You may make it start acquisition of the broadcast cooperation application prepared for the said broadcast programs, without waiting for the broadcast start time of a program. That is, information (location information such as URL) for specifying the acquisition destination of the broadcast cooperative application is described in EIT information including detailed information of each broadcast program. In this way, the broadcast receiving apparatus 100 can grasp the information on the acquisition destination of the broadcast cooperative app prepared for each broadcast program when the broadcast program is selected with the program selection cursor 173e4. Become. Therefore, the broadcast receiving apparatus 100 can start acquiring the broadcast cooperative app before the broadcast start time of the broadcast program is reached.

In the case where the broadcast program for which the viewing reservation and / or the recording reservation has been made is a broadcast program corresponding to the broadcasting / communication cooperation service and is a broadcast program capable of cooperative operation with the mobile terminal device, The broadcast cooperation application (terminal side) prepared in the above may be started before the broadcast start time of the broadcast program by the same processing as described above. In addition, as shown in FIG. 16B, information on the acquisition destination of the broadcast cooperative app (terminal side) prepared for the mobile terminal device (
2D barcode 173e5 etc. indicating location information such as URL) EPG display screen 1
It may be displayed on 73e to prompt the user to download a broadcast cooperative app (terminal side) prepared for the mobile terminal device.

As described above, if the broadcast receiving apparatus 100 refers to the acquisition destination information of the broadcast cooperative app included in the EPG information and starts acquiring the broadcast cooperative app before the broadcast start time of the broadcast program is reached. It becomes possible to distribute the load of the service provider server 400 that stores the broadcast cooperation application. In addition, even when the network communication speed between the service provider server 400 and the information display terminal 100 is insufficient, the broadcast cooperative app can be effectively used immediately after the broadcast program starts broadcasting. become.

FIG. 17 is an operation sequence diagram illustrating an example of an acquisition sequence of a broadcast cooperative app when a broadcast program viewing reservation and / or recording reservation is made on the EPG display screen 173e.

During viewing of the digital broadcast service, the main control unit 101 of the broadcast receiving apparatus 100 acquires the program information data sequence output from the first separation unit 132 (S701). When the user makes an EPG screen activation request using the operation terminal (S702), the EPG display screen 1 is displayed on the video display unit 173.
73e is displayed (S703). When the user selects an arbitrary broadcast program on the EPG display screen 173e using the operation terminal to make a viewing reservation and / or recording reservation for the broadcast program (S704), the main control unit 101 performs the first separation. The program information data string acquired from the section 132 is confirmed (S705), and further, the location of the acquisition destination of the broadcast cooperative application linked to the broadcast program for which the viewing reservation and / or recording reservation has been made is confirmed (S706).

After the processing of S706, the application control unit 161 transmits a transmission request for the broadcast cooperative app to the predetermined service provider server 400 via the LAN communication unit 121 based on the confirmed URL (S707). The service provider server 400 that has received the transmission request for the broadcast cooperative application performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores it in the application storage area 4013. Distribution of the predetermined broadcast cooperation application memorize | stored is performed via the LAN communication part 421 (S708). Subsequently, the application control unit 161 converts the predetermined broadcast cooperative app received from the service provider server 400 received via the LAN communication unit 121 into the RA.
The data is cached in the M104 or the storage 110 (S709).

According to the above-described direction transmitting / receiving apparatus 100 of the present embodiment, a function with higher added value can be executed.

Hereinafter, Example 2 of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified. For this reason, below, the difference between a present Example and Example 1 is mainly demonstrated, and in order to avoid duplication about a common point, description is abbreviate | omitted as much as possible.

Although the embodiment in the case of performing the portable information terminal cooperation process (hereinafter referred to as the terminal cooperation) has been described in the first embodiment, a more detailed embodiment will be described.

When performing cooperation with the portable information terminal, the portable information terminal 70 in the same house as the broadcast receiving apparatus 100 is used.
There is a case where it is desired to restrict the use of terminal cooperation only to 0 (this restriction is hereinafter referred to as the same house restriction)
. For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), the display screen of the broadcast receiving apparatus 100 and the display screen of the portable information terminal 700 are closely related, or the broadcast receiving apparatus 100 This is the case where the user of the portable information terminal 700 wants to surely view the displayed advertisement video.

The point that must be considered as a procedure is a determination as to whether or not the target broadcast cooperation application imposes the same in-house restriction. If it is assumed that all broadcast cooperation apps have the same home restriction, this determination is not necessary. However, if there is no restriction, the broadcast receiving device 100 may provide control information regarding the presence of the same home restriction. Need to get and change the operating procedure. The control information regarding the presence or absence of this restriction may be acquired from a broadcast signal (for example, described as an AIT item) or may be acquired from a server designated by a broadcast station.

In the present embodiment, including the above procedure, a procedure for guaranteeing that the portable information terminal 700 exists in the same home as the broadcast receiving device 100 will be described.

Usually, devices existing in the same house exist on a local network connected to the same router device 210. Therefore, since the portable information terminal 700 is connected to the same local network as the broadcast receiving device 100, it can be determined that the portable information terminal 700 exists in the same home. Note that a known method may be used to determine whether the target device is connected to the local network, and a description thereof is omitted.

Even if the portable information terminal 700 is not on the local network, NFC, Blu
It can also be determined that the user is in the same home by directly communicating with the broadcast receiving apparatus 100 by eTooth, infrared communication, or the like. In this case, communication for acquisition of broadcast cooperation applications etc.
The direct communication described above or mobile phone communication may be used.

As described above, a plurality of methods for confirming the presence in the same house are conceivable, but which method is used is described in, for example, the AIT and read by the broadcast receiving apparatus 100.

Furthermore, once it can be confirmed that the portable information terminal 700 exists in the same house, it may be assumed that the portable information terminal 700 exists in the same house until the end of the program, or a certain valid time (for example, 10 minutes)
It is also possible to use a method in which it is assumed that it exists in the same house within the effective time, but if the effective time has passed, it is not considered to exist in the same house unless newly confirmed. This valid time is described in, for example, AIT and read by the broadcast receiving apparatus 100.

Furthermore, for example, an event signal is set in the broadcast signal at an arbitrary time during the program progress,
A method of confirming that the portable information terminal 700 exists in the same house every time this event signal is received can be adopted.

  It is also possible to use a combination of the former two methods.

Next, a specific procedure for permitting terminal cooperation only for the portable information terminal 700 existing in the same house will be described. In this embodiment, when the portable information terminal 700 acquires a broadcast cooperation application,
Alternatively, a restriction is set when acquiring information used by the broadcast cooperation application (hereinafter, information used by the broadcast cooperation application and the broadcast cooperation application, specifically HTML documents, streaming video, etc., which are broadcast together) Called linkage information). There are two types of broadcast cooperation information acquisition methods: communication acquisition acquired from the broadcast station server 300 or the operator server 400 and broadcast acquisition acquired from broadcast waves. In the case of communication acquisition, there are two types: a method of acquiring after the start of broadcast reception and a method of acquiring before the start of broadcast reception. Furthermore, in the case of communication acquisition, when the broadcast receiving apparatus 100 acquires once and the portable information terminal 700 acquires from the broadcast receiving apparatus 100, and the portable information terminal 700 acquires directly from the broadcast station server 300 or the operator server 400. There is. There are various methods, but when viewed from the portable information terminal 700, the mobile information terminal 700 can be broadly divided into two cases: acquisition from the broadcast receiving device 100 and acquisition from the broadcast station server 300 or the operator server 400.

In the present embodiment, a case where the portable information terminal 700 acquires broadcast cooperation information from the broadcast receiving apparatus 100 will be described, and a case where the mobile information terminal 700 acquires from the server will be described in the next embodiment.

  FIG. 18A shows the procedure of this embodiment.

First, before performing terminal cooperation, in each of the portable information terminal 700 and the broadcast receiving device 100,
The cooperation control application which is an application for controlling terminal cooperation is activated (S1000).
1, S10002). In this state, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100 (S10003). Next, AIT is acquired from the broadcast signal (S1000).
4). From this AIT information, it is determined whether the target mobile information terminal application has the same in-home restriction (S10006). If there is a restriction, the process proceeds to step S10008, and the first stage when the terminal cooperation request is made. Then, the process proceeds to step S10009, and it is determined whether the portable information terminal 700 for which the terminal cooperation request has been made is in the same home as the broadcast receiver 100 (S10).
009). As a result of the determination, if it is determined that they are not in the same home, a response indicating that the cooperation is not permitted is sent to the cooperation control application on the portable information terminal side, and the process is terminated (S10011).

Here, in the first place, if it is assumed that all terminal-linked apps have the same in-house restrictions, S
The determination of 10006 is not performed and skipped. If there is both an application with the same home restriction and an application without the same house restriction, the determination in S10006 is performed.

If it is determined that the portable information terminal 700 is in the same home or is an app that does not have the same home restriction, the process advances to step S10012 to perform a broadcast cooperation application-related service. This service (S100
12), the broadcast cooperation information distribution request (S10013) from the portable information terminal 700 is processed, and the broadcast cooperation information is distributed to the portable information terminal 700 (S10018). The broadcast cooperation information includes information received by the broadcast receiving device 100 from the distribution server (S10014, S1001).
5, S10016), acquired from the broadcast signal (S10017), broadcast receiving apparatus 100
There are things that are remembered. Reception of broadcast cooperation information by the broadcast receiving apparatus 100 (S100
16, S10017) is a broadcast cooperation information distribution request (S1001) from the portable information terminal 700.
In addition to the case of 3), there may be cases where the broadcast receiving apparatus 100 acquires autonomously, or acquisition based on the occurrence of an event from a broadcast signal. And the portable information terminal 70
Distribution of broadcast cooperation information to 0 (S10018) may also be spontaneous from the broadcast receiving apparatus 100 side.

After a series of broadcast related information reception (acquisition) and distribution processing is completed, it is determined whether or not the broadcast receiving apparatus 100 continues to watch the same program (S10019). A response indicating that the cooperation is not permitted is sent to the cooperation control application, and the process ends (S100).
20).

If viewing continues, the process returns to the procedure of S10005, and if there is a home restriction, it is confirmed whether the portable information terminal 700 is in the same house (S10009), but a preset valid time has passed since the previous confirmation. Or whether a confirmation request (S10007) from the broadcast signal or the distribution server has been generated since the previous confirmation (S10008). If neither condition is satisfied, whether the user is in the same house Confirmation (S10009) is not performed,
The process proceeds to execution of the next broadcast cooperative application-related service (S10012) via S10010. Here, the confirmation request (S10008) from the broadcast signal is described as being acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Furthermore, this confirmation request may be described in the AIT.

The procedure described above is a loop processing procedure for the broadcast signal, the broadcast receiving device 100, the portable information terminal 700, and the entire distribution server in the section indicated by the arrow in S10022. The confirmation request in S10007 may be at any timing in the loop.

Further, the authentication information described in the AIT may be incorporated in the authentication key used for authentication (S10015) at the distribution server. Thereby, it can confirm that it is a legitimate authentication request. Further, if the authentication information described in the AIT is changed as the program progresses, and the authentication server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program That you ’re watching In this case, the AIT information is appropriately read and updated (S10021). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method for substantially changing the authentication information, a method of changing the URL of the distribution server itself as the program progresses can be used.

As described above, the portable information terminal 700 receives a broadcast signal every time a preset valid time is executed or a confirmation request is received from a broadcast signal or a distribution server while executing the broadcast cooperation application related service (S10012). By checking whether it is in the same house as the device 100,
Broadcast-related applications that have the same in-house restrictions can be executed appropriately. Furthermore, by using the authentication information incorporated in the broadcast signal for authentication at the distribution server, the validity of the distribution request can be ensured, and if the authentication information of the broadcast signal is appropriately changed, the same program You can also confirm that you are watching

According to the portable information terminal cooperation technology according to the present embodiment described above, it is possible to realize the same in-home restriction for the portable information terminal that cooperates with the broadcast receiving apparatus.

In the present embodiment, a case where the portable information terminal 700 acquires broadcast cooperation information from a distribution server will be described.

  FIG. 18B shows the procedure of this example.

First, before performing terminal cooperation, in each of the portable information terminal 700 and the broadcast receiving device 100,
The cooperation control application which is an application for controlling terminal cooperation is activated (S1010).
1, S10102). In this state, the portable information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100 (S10103). Next, AIT is acquired from the broadcast signal (S1010).
4). Information such as a URL related to the distribution server is acquired from the information of the AIT, and the information is transmitted to the portable information terminal 700 (S10105). Next, a time confirmation request is issued from the broadcast receiving apparatus 100 to the distribution server (S10106), and based on this request, time information is transmitted from the distribution server to the broadcast receiving apparatus 100 (S10107). As a result, the subsequent authentication key issuance (S10115) can be performed in accordance with the time of the distribution server, but may be omitted if there is no problem in time lag.

  Thereafter, the loop control indicated by the arrow in S10127 is entered.

First, the mobile information terminal 700 issues an authentication key issue request or broadcast cooperation information distribution request to the broadcast receiving apparatus 100 (S10109). The authentication key is used in a broadcast cooperation information distribution request to the distribution server in the subsequent stage (S10125). The broadcast cooperative distribution request in S10109 is a distribution request for information acquired from a broadcast signal, and corresponds to the procedure in S10126 in the subsequent stage.

In any case, when the request of S10109 is issued from the portable information terminal, it is determined whether or not it is a broadcast cooperation application with the same in-home restriction (S10111), and if there is a restriction, the next step S1011 is performed.
If not, the procedure of S10112 is skipped and the procedure proceeds to S10114. If all the broadcast cooperative apps have the same in-house restriction, the determination in S10111 is not performed, and the process proceeds to S10112. In S10112, it is determined whether or not the portable information terminal that has issued the request is in the same house, and if not, the terminal cooperation is terminated (S10113). If in the same house, the requested procedure, acquisition of broadcast cooperation information from the distribution server (S10125) or acquisition of broadcast cooperation information from the broadcast signal (S10126) is performed. Since there may be acquisition from a broadcast signal in addition to acquisition from the distribution server, the procedure of S10126 is also described.

  First, the acquisition procedure (S10125) of the broadcast cooperation information from a delivery server is demonstrated.

First, an authentication key requested from the information cooperation terminal 700 is issued from the broadcast receiver 100. At this time, the authentication key includes time information at the time of issuance, and within a predetermined time (for example, 1
It is assumed that it is effective only for 0 minute). The distribution server confirms the authentication information including whether or not the authentication key is within the valid time, and if the authentication is OK, the distribution of broadcast cooperation information is permitted. Thereafter, distribution of information is permitted within the valid time, but the distribution is stopped when the valid time has passed. For example, the streaming video cannot be viewed after the valid time has passed.

The valid time set in advance may be held in the distribution server, or the broadcast receiving apparatus 100.
May be acquired from a broadcast signal (for example, AIT) and the valid time information may be incorporated into the authentication key. The mobile information terminal 700 is notified in advance of information about the valid time, and requests the issuance of an authentication key before the valid time expires. Alternatively, the effective time is managed by the broadcast receiving apparatus 100, and it is confirmed that the portable information terminal 700 is in the same house before the effective time expires, and then automatically from the broadcast receiving apparatus 100 to the portable information terminal 700. An authentication key may be issued.

The valid time may be the same in one program or may be changed according to the progress of the program. Further, if there is no valid time setting, it may be handled that once authentication is performed, the authentication is valid during program viewing.

Furthermore, the authentication information described in the AIT may be incorporated in the authentication key used for authentication (S10117) at the distribution server. Thereby, it can confirm that it is a legitimate authentication request. Further, if the authentication information described in the AIT is changed as the program progresses, and the authentication server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program That you ’re watching In this case, the AIT information is appropriately read and updated (S10124). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method for substantially changing the authentication information, a method of changing the URL of the distribution server itself as the program progresses can be used. The URL change in this case is the case where the distribution server is the same and the entrance is different. However, the URL may be changed to a new distribution server due to a change in the broadcast cooperation application or the like. In this case, every time a change is made, the procedure of distribution server information transmission (S10105), time confirmation request (S10106), and time information transmission (S10107) is performed.

  Next, the procedure (S10126) for acquiring broadcast cooperation information from a broadcast signal will be described.

In this case, after it is confirmed that the portable information terminal 700 is in the same house, the broadcast receiving apparatus 100 acquires broadcast cooperation information from the broadcast signal (S10119), and then distributes the information to the portable information terminal 700. (S10120).

In addition, when changing broadcast cooperation information with advancing of a program, notification of a change may be issued from a broadcast signal (S10110), and broadcast cooperation information may be acquired by using the notification as a trigger. In that case, if it is acquisition from a delivery server, an authentication key will be issued to the portable information terminal from the broadcast receiving apparatus 100 (S10115), and it will be notified that there was a change notification. If it is within the valid time, the authentication key issuance may be omitted and only the notification of the change notification may be given. In the case of acquisition from a broadcast signal, the broadcast receiving apparatus 100 acquires information (S10120) and distributes it to the portable information terminal (S10120). In the case of acquisition from a broadcast signal, it may be confirmed that the portable information terminal 700 is in the same home for each change notification, and the confirmation is omitted if it is within the valid time as in the second embodiment. It doesn't matter. Here, a change notification from the broadcast signal (S101)
10) is described so as to be acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Further, this change notification may be described in the AIT.

After the reception (acquisition) and distribution processing of a series of broadcast-related information is completed, it is determined whether or not the broadcast receiving device 100 continues to watch the same program (S10121). A response indicating that the cooperation is not permitted is sent to the cooperation control application, and the process ends (S101).
23). If the viewing is continued, the process returns to S10108, and the loop process S10127 is continued.

Thus, by including the time information in the authentication key used for authentication of the distribution server and managing the effective time, it can be confirmed that the portable information terminal 700 is regularly in the same home as the broadcast receiving device 100, Broadcast-related applications that have the same in-house restrictions can be executed appropriately.
Furthermore, by using the authentication information embedded in the broadcast signal for authentication on the distribution server,
The validity of the distribution request can be ensured, and if the broadcast signal authentication information is appropriately changed, it can be confirmed that the same program is being viewed.

According to the portable information terminal cooperation technology according to the present embodiment described above, even when the portable information terminal that cooperates with the broadcast receiving apparatus acquires the broadcast cooperation information from the distribution server, it is possible to realize the same in-home restriction. .

In the second and third embodiments, the procedure for realizing the same in-house restriction in terminal cooperation has been described. However, depending on the broadcast cooperation application, use from outside the house may be permitted. In this embodiment, such a case will be described. For example, when a program such as TV shopping is publicity / advertising, it is desirable for broadcasters to be able to use a broadcast cooperation application regardless of whether it is inside or outside the house. In the case of such a program, once registered in the broadcast receiving apparatus 100, the use of the broadcast cooperation application may be permitted regardless of whether the portable information terminal 700 is in the house. In this case, the broadcast video itself is converted into streaming data, and the broadcast receiver 1
If there is a broadcast cooperation application that is distributed from 00 to the portable information terminal 700 via the Internet, the convenience is further enhanced. The streaming data may be encrypted by the broadcast receiving apparatus 100 for copyright protection. Whether or not the broadcast cooperative application permits use from outside the home, including distribution of broadcast video outside the home, is described in data (for example, AIT) in the broadcast signal.

A specific procedure is shown in FIG. 18C. Since part of the procedure is common to the second and third embodiments, the description of the same parts as those of the second and third embodiments is omitted. If there is a terminal cooperation request (S10203) from outside the house, the broadcast receiving apparatus 100 confirms whether the request source is a registered portable information terminal if the application is permitted to be used outside the house ( In S10205), the cooperation is permitted. Here, if necessary, authentication may be performed between the portable information terminal 700 and the broadcast receiving apparatus 100 in order to protect the copyright of the broadcast video and the broadcast cooperation information (
S10207). In this case, the authentication may be authentication in an authentication server (S
10207). Information about whether copyright protection is necessary and information about an authentication method for copyright protection is acquired from a broadcast signal (for example, described in AIT), and control is performed accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving apparatus 100 is followed. For example, a predetermined copyright protection process may be performed. Further, when such information is not stored in the broadcast signal, the broadcast receiving device 1
It may be determined in advance that no copyright protection processing is performed at 00.

Specific examples (1) to (4) of authentication for copyright protection are shown below. Only one of the following authentications may be performed. Or you may perform combining the some authentication illustrated below. Moreover, you may perform combining the authentication illustrated below and the other authentication process which is not illustrated below.

(1) Authentication by ID and Password When registering the portable information terminal 700 in the broadcast receiving apparatus 100, the ID and password are issued, and the broadcast receiving apparatus 100 permits cooperation by confirming this ID and password.

(2) Use of encryption key In addition to the authentication using the ID and password, an encryption key for decrypting encrypted video data and the like is transmitted from the broadcast receiving apparatus 100 to the portable information terminal. This encryption key may be acquired from a broadcast signal (for example, described in AIT).

(3) Use of authentication server A method of issuing an encryption key for decrypting encrypted video data or the like from the authentication server.
The portable information terminal 700 transmits the ID and password to the authentication server and acquires the encryption key. In this case, the location information (specifically, URL) of the authentication server is used as a broadcast signal (for example, A
And the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700, so that safety is further improved. If the mobile information terminal 700 cannot obtain the encryption key, the video or the like cannot be decrypted. Therefore, by requesting the authentication with the authentication server from the broadcast receiving apparatus 100, it is possible to authenticate the copyright, or the mobile information terminal Authentication may be completed by notifying the broadcast receiving apparatus 100 from 700 that the encryption key has been acquired. Note that charging by the authentication server may be performed.

(4) Mutual authentication of encryption keys The encryption keys possessed by the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated, and the confirmation of copyright protection is made by taking confirmation.

If the information stored in the broadcast signal indicates that copyright protection by a predetermined method is necessary, if the copyright protection cannot be authenticated by the predetermined method, terminal cooperation is not permitted.
Even when the broadcast signal is not specified and authentication is performed by the default method of the broadcast receiver 100, if the copyright protection cannot be authenticated by the default method, terminal cooperation is not permitted.

When the terminal cooperation is permitted, the request from the portable information terminal 700 (S10211), the broadcast receiving apparatus 100 is not confirmed without checking whether the portable information terminal 700 exists in the same house.
In accordance with a request from the broadcast signal (S10210), distribution of broadcast cooperation information to the portable information terminal 700 (S10217), issuance of an authentication key for the distribution server (S10212)
)I do. In this case, the control that sets the valid time may not be performed. The portable information terminal 700 outside the home acquires broadcast cooperation information from the broadcast server 100 or the distribution server using the issued authentication key (S10215). In addition, authentication information (for example, described in AIT) acquired from the broadcast signal is incorporated in the authentication key issued by the broadcast receiving apparatus 100, and the distribution server is an authentication key in which the authentication information acquired from the broadcast signal is embedded. If access is permitted, it is possible to further optimize use outside the home.

In addition, there may be cases where it is better not to allow unlimited use of broadcast-linked apps, such as when discounting as a program viewing premier. In such cases, authentication may be performed once with a portable information terminal in the same house. It is preferable to use the distribution server even if it is not in the same house. In this case, the portable information terminal 700 may not be registered in the broadcast receiving device 100.

A specific procedure in this case is shown in FIG. 18D. Since some of the procedures are the same as those in FIG. 18C, the description of the overlapping portions is omitted. First, in the state where the portable information terminal 700 is in the same house as the broadcast receiving device 100, the portable information terminal 700 transmits the broadcast receiving device 10 to the broadcast receiving device 100.
A terminal cooperation request is made to 0, and the broadcast receiving apparatus 100 confirms that the portable information terminal 700 is in the same home (S10305) and permits cooperation. Here, if necessary,
In order to protect the copyright of the broadcast video and the broadcast cooperation information, authentication may be performed between the portable information terminal 700 and the broadcast receiving apparatus 100 (S10307). In that case, the said authentication may be the authentication in an external authentication server. Broadcast signal (for example, described in AIT) Information on whether copyright protection is necessary and information on copyright protection authentication method
And control accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving apparatus 100 is followed. For example, a predetermined copyright protection process may be performed. Further, when such information is not stored in the broadcast signal, it may be determined in advance that copyright protection processing is not performed in the broadcast receiving apparatus 100.

Specific examples (5) to (7) of authentication for copyright protection are shown below. Only one of the following authentications may be performed. Or you may perform combining the some authentication illustrated below. Moreover, you may perform combining the authentication illustrated below and the other authentication process which is not illustrated below.

(5) Use of Encryption Key While the portable information terminal 700 is in the same house, the encryption key for decrypting the encrypted video data and the like is transmitted from the broadcast receiving apparatus 100 to the portable information terminal. This encryption key may be acquired from a broadcast signal (for example, described in AIT). Authentication is performed by handing over this encryption key in the same house. Furthermore, if the encryption key cannot be acquired from the broadcast signal only at a certain point in time of the program and the delivery of the encryption key to the portable information terminal 700 is limited to the same home, the user must be in the same home at that time. Limits can be set and it can be used to grant a premium to viewing.

(6) Use of authentication server A method of issuing an encryption key for decrypting encrypted video data from the authentication server.
The portable information terminal 700 transmits the ID and password to the authentication server and acquires the encryption key. In this case, the location information (specifically, URL) of the authentication server is used as a broadcast signal (for example, A
And the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700, so that safety is further improved. If the mobile information terminal 700 cannot obtain the encryption key, the video or the like cannot be decrypted. Therefore, by requesting the authentication with the authentication server from the broadcast receiving apparatus 100, it is possible to authenticate the copyright, or the mobile information terminal Authentication may be completed by notifying the broadcast receiving apparatus 100 from 700 that the encryption key has been acquired. Access to the authentication server may be performed inside or outside the house, but the location information of the authentication server can be acquired from the broadcast signal only at a certain point in time of the program, and the location information is sent to the portable information terminal 700. If delivery is limited to the same house, a restriction that the person must be in the same house at that time can be set, and it can be used for giving a premium to viewing. Note that charging by the authentication server may be performed.

(7) Mutual authentication of encryption keys The encryption keys possessed by the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated and confirmed to be copyright protection authentication. This authentication may be performed inside or outside the house.

If the information stored in the broadcast signal indicates that copyright protection by a predetermined method is necessary, if the copyright protection cannot be authenticated by the predetermined method, terminal cooperation is not permitted. Even when the broadcast signal is not specified and authentication is performed by the default method of the broadcast receiver 100,
If the copyright protection cannot be authenticated by the default method, terminal cooperation is not permitted. Since the procedure after allowing the terminal cooperation is common with the procedure of FIG.

According to the portable information terminal cooperation technique according to the present embodiment described above, it is possible to realize use of the portable information terminal linked with the broadcast receiving apparatus from outside the house while paying attention to copyright protection.

In an actual usage situation, it is more desirable to easily know whether or not there is a terminal cooperation application by a program and which terminal cooperation application can be used. In the present embodiment, a display method of the availability status of the terminal cooperation application will be described.

FIG. 19A shows a launcher screen (173b1) of a broadcast cooperative app when there is a terminal cooperative app.
This is an example of 1). Broadcast-linked apps are displayed with framed icons. A broadcast cooperation application (173b12 to 173b14) for the broadcast receiving apparatus 100 and a broadcast cooperation application (173b15 to 173b17) for the portable information terminal that are linked to the program being viewed are displayed. In the case of this example, the status of the application is indicated by the thickness of the frame line surrounding the character string and the color in the frame. Main body application A, B (173b12, 173b13) and terminal application A, B (173b15, 173)
b16) is available, and the main body application C (173b14) and the terminal application (173)
b17) is an unusable state. The state in which the terminal application cannot be used means that none of the portable information terminals 700 that are communicable with the broadcast receiving apparatus 100 have a function of executing the application.

FIG. 19B is a screen after the terminal application A is selected in FIG. 19A. The state of each portable information terminal 700 regarding the terminal application A is shown. The portable information terminal displayed on this screen is a terminal that has been linked or registered with the broadcast receiving apparatus 100 in the past.

The mobile terminal 1 (173b22) and the mobile terminal 2 (173) whose icon frame lines are solid lines
b23) is in a state where communication with the broadcast receiving apparatus 100 is possible, and the mobile terminal 3 (173b24) and the mobile terminal 4 (173b25) whose frame lines are dotted are not in a state where communication with the broadcast receiving apparatus 100 is possible. Show. In addition, the mobile terminal 1 (173b2) whose icon frame is white
2) and the mobile terminal 3 (173b24) have a function to execute the terminal application A, and the mobile terminal 2 (173b23) and the mobile terminal 4 (173b25) in which the frame is gray do not have a function to execute the terminal application A It is shown that. Further, when an application is already running on the terminal, a design icon indicating that may be used.

  An example of an icon is as follows because it is easier to understand visually if a pattern is used.

FIG. 19C is an example of a launcher screen (173b31) showing a list of broadcast cooperative apps. In addition to the broadcast receiving device 100, icons are shown for each type of portable information terminal 700. 17
3b32 and 173b33 are icons indicating the broadcast receiving device 100, and 173b34 and 1
73b35 is an icon indicating the smart phone type portable information terminal 700, and 173b36
Is an icon indicating the portable information terminal 700 of the head mounted display type. Each app is for a device indicated by an icon.

In FIG. 19C, when the application cannot be used, a mark indicating that the application cannot be used is displayed on the image of the device (in this case, a circle is a diagonal line). Further, regarding the broadcast receiving apparatus 100, when the application is already being executed, a mark indicating that (in this case, a dot in a circle) may be displayed in an overlapping manner. By this display, it is possible to prevent a useless operation of proceeding with the launcher procedure even though it has already been executed. In the case of the portable information terminal 700, it is also possible to display a mark indicating that the application is being executed when the application is being executed on all the terminals that are communicable with the broadcast receiving apparatus and can execute the application.

FIG. 19D shows a screen (173 after selecting application C (173b34) in FIG. 19C.
b41). A state of the portable information terminal 700 of a type corresponding to the application C is shown. In this screen, if the portable information terminal 700 does not have a function for executing the broadcast cooperative app, if it is not in a state where it can communicate with the broadcast receiving device 100, or if the broadcast cooperative app is already being executed, this is indicated. The mark to represent is displayed over the icon. In this example, if there is no execution function, a circle with slashes (173b44, 173b46), a triangle with an exclamation mark (173b45, 173b46) if communication is not possible, and a circle if already running The mark (173b43) is displayed.

Furthermore, it is desirable that there is a display method in which it is possible to know that there is a broadcast cooperative app when the situation changes without having to start the launcher every time. For example, when the power is turned on, when the channel is changed, when the broadcast cooperation application is changed at the beginning of the program or even during the program, the communication state between the broadcast receiving device 100 and the portable information terminal 700 is changed. If the application execution status changes, the icon is displayed for a predetermined time and the state at that time is displayed.

FIG. 19E shows an example in that case. When an icon indicating the type of each device is displayed, it indicates that there is a broadcast cooperation application corresponding to that type of device. in this case,
A circle with diagonal lines indicates that there is no device that can execute the application in that type of device that is in a usable state. A dot in a circle indicates that the app is running on all devices of that type that are ready for use.

In addition, when the status of each broadcast receiving apparatus 100 is also displayed, the convenience is further enhanced particularly when used from outside the house. In this example, while receiving the program,
A display example of receiving another program, vacant, and having another program reserved (when recording of another program is reserved from the middle of the program) is shown. Here, when there are a plurality of tuners in the broadcast receiving apparatus 100, the convenience is further different if the status is displayed for each of the plurality of tuners. Table 102
In 02, the branch number indicates the distinction between tuners in the same apparatus. For example, receiving device B
-1, the receiving device B-2 is a tuner in the same broadcast receiving device 100. In the case of terminal cooperation, if broadcast video and audio can be received as streaming data, the broadcast receiving device 10
It is not necessary to use the 0 video section, and if the tuner in the broadcast receiving apparatus 100 can be used, broadcasting can be used. Therefore, it is convenient to know the usage status of each tuner.

In order to perform the display described in this embodiment, for each broadcast cooperation app, information on whether the app is compatible with the broadcast receiving device 100 or what type of mobile information terminal 700 is compatible. There must be. In addition, information for executing the corresponding application in the broadcast receiving device 100 and the portable information terminal 700 is necessary.
