That is, the viewer U3 is a person who views the receiver 60-3 while using (operating) the terminal device 90, for example.

  The broadcasting station apparatus group 10 and the transmission antenna 20 are an apparatus group and facilities managed by a broadcasting station that is a broadcasting company. The service server group 40 is a group of devices managed by either a broadcasting station or a service provider. The receiver 60 and the terminal device 90 are devices that a viewer has.

  The broadcasting / communication cooperation system 1 is a broadcasting communication in which a broadcasting station cooperates, for example, a broadcasting service provided by an integrated digital broadcasting service (ISDB) system with a distribution service (communication service) provided by a service provider. Realize linked services.

  For example, the receiver 60 that receives the broadcast communication cooperation service acquires a broadcast program supplied from the broadcast station apparatus group 10 by the broadcast service, that is, program content data. The program content data includes broadcast program content data and various control information. This program content data includes advertisement content data. The advertising content data is content data including contents that a broadcast station introduces a program, content data including contents that a company or the like advertises a product or service, or advertises a corporate image. Then, the receiver 60 acquires an application program (hereinafter referred to as an application) associated with the acquired program content data from the service server group 40, and executes the acquired application. The application is an execution program for realizing the broadcasting / communication cooperation service in the receiver 60. Then, the receiver 60 acquires the distribution content data specified by the execution of the application from the service server group 40, and reproduces the program content data and the distribution content data by linking or associating them.

  An application supplied from the broadcast station apparatus group 10 to the service server group 40, that is, an application provided by the broadcast station is referred to as a broadcaster provided application. An application created by a service provider or an individual is called a service provider-provided application. Furthermore, among the service provider-provided applications, an application certified by the broadcasting station is called a certified application, and an application not certified by the broadcasting station is called a non-certified application.

Next, each configuration of the broadcasting / communication cooperation system 1 will be described.
The network 30 is a telecommunication line that connects the broadcasting station apparatus group 10 and the service server group 40, and is also referred to as an inter-provider network. The network 30 is a computer network capable of communicating by, for example, IP (Internet Protocol).

Further, the terminal device 90 and the receiver 60-3 communicate with each other through the network 50 or through a communication path (home LAN, wireless LAN, Universal Serial Bus (USB), etc.) different from the network 50.

The broadcast station device group 10 generates a stream in which various control information related to the content and the application is multiplexed on the content for broadcasting produced by a broadcast station, a program production company, or the like. As contents for broadcasting, there are program contents broadcast according to a broadcast schedule determined by a broadcasting station, and emergency contents broadcast regardless of the broadcast schedule. The emergency content is, for example, content used for emergency alert broadcasting. The stream is, for example, a transport stream (TS) according to the MPEG-2 system standard.
The broadcast station apparatus group 10 converts the generated stream into a digital broadcast broadcast signal, and transmits the broadcast signal to the transmission antenna 20.

Here, a transmission protocol stack of a broadcast signal for digital broadcasting will be described. As described above, the broadcast station apparatus group 10 stores video data, audio data, various control information, and the like in, for example, transport stream packets (TS packets), and multiplex-transmits these TS packets by time division.
The TS packet includes Program Specific Information / Service Information (PSI / SI) as a section. PSI / SI includes information indicating the type of data stored in the TS packet, information indicating the type of content, and the like.

  As a TS packet transmission method, there are a method of transmitting data using sections and a method of transmitting data using packetized elementary stream (PES) packets (data stream transmission method). As a system for transmitting data using sections, there are a data carousel transmission system and an event message transmission system. The data carousel transmission method is a method in which the broadcasting station apparatus group 10 repeatedly transmits one or a plurality of data (modules) at a constant period. The event message transmission method is a method in which the broadcasting station device group 10 transmits a trigger signal to the receiver 60. The event message transmission method is a method used when transmitting a message with a small amount of data. The data stream transmission method is a method used when transmitting data having real-time properties such as video data, audio data, caption data, control information for controlling synchronization with other streams, and the like.

  The specifications of the stream and the broadcast signal are defined by, for example, ARIB (Association of Radio Industries and Broadcast) standard.

  The broadcast station apparatus group 10 supplies the service server group 40 with applications, distribution content data (distribution content data), and advertisement control information produced and created by the broadcast station. The distribution content data is, for example, program content data that has already been broadcast, advertisement content data, or the like. The advertisement control information is information in which a presentation start time and a presentation end time of advertisement content data in a broadcast program are associated with information for identifying advertisement content data that can be presented in the broadcast program for each broadcast program.

  The transmission antenna 20 receives a broadcast signal transmitted from the broadcast station apparatus group 10, converts the broadcast signal into a broadcast radio wave, and radiates it into the air.

The service server group 40 takes in and stores the application and distribution content data produced and created by the broadcasting station and the advertisement control information supplied from the broadcasting station apparatus group 10.
In addition, the service server group 40 stores an application produced by a service provider and distribution content data.

Further, the service server group 40 supplies the application selected in response to the application acquisition request supplied from the receiver 60 to the receiver 60 that is the acquisition request source.

Further, the service server group 40 supplies the distribution content data selected in response to the content acquisition request supplied from the terminal device 90 to the terminal device 90 that is the acquisition request source.

  Further, the service server group 40 takes in the viewer identification information and the receiver operation history information supplied from the receiver 60. The viewer identification information is information for identifying the viewer, as will be described in detail later. The receiver operation history information is history information including information for specifying the operation of the receiver 60 (information indicating the operation content) and information indicating the operation date and time.

Further, the service server group 40 takes in the viewer identification information and the terminal usage history information supplied from the terminal device 90. The terminal usage history information is history information including information indicating the usage contents of the terminal device 90 and information indicating the usage date and time.
Receiver operation history information and terminal usage history information that share viewer identification information are history information related to operations by the viewer corresponding to the viewer identification information, and are referred to as viewer-side history information.

The service server group 40 is associated with the viewer identification information by analyzing the viewer side history information (receiver operation history information and / or terminal usage history information) for each viewer identification information. The viewer's interests, preferences, interests, hobbies and the like (hereinafter referred to as interests) are estimated, and viewer preference information is generated. A specific example of the viewer preference information will be described later.
The service server group 40 selects the advertisement content data as the personalized advertisement content data based on the advertisement control information and the viewer preference information for each viewer identification information. That is, for each viewer, the service server group 40 has advertisement content data having contents related to or corresponding to the viewer's interest and the like and adapted to the advertisement time indicated by the advertisement control information as personal advertisement content data. select.
The service server group 40 supplies the selected personal advertisement content data to the corresponding receiver 60 and / or the terminal device 90.

The receiver 60 acquires the application associated with the fetched program content data from the service server group 40 and executes it. The receiver 60 acquires the distribution content data specified by the execution of the application from the service server group 40, and reproduces the program content data and the distribution content data by linking or associating them. For example, the receiver 60 activates and executes an application (individual advertisement presentation application) that presents an advertisement for individuals corresponding to the viewer at the advertisement presentation time in a broadcast program. This personal advertisement presentation application is a broadcaster-provided application. The receiver 60 executing the personalized advertisement presentation application replaces the advertising content in the program content being presented with advertising content (personal advertising content) having contents related to or corresponding to the interest of the viewer of the device. Present.

The receiving device 60 controls the output method of program content data and distribution content data based on application presentation control information which is one of control information.
The receiver 60 can operate in conjunction with the terminal device 90 by being connected to the terminal device 90.

The receiver 60 stores viewer identification information. The viewer identification information is information for identifying a viewer who views a broadcast program by the own device, and is device identification information unique to the receiver 60, for example. Alternatively, the viewer identification information is arbitrary identification information set in the receiver 60 by the viewer. For example, in FIG. 1, the viewer of the receiver 60-1 is the viewer U1, and the viewer identification information stored in the receiver 60-1 is information for identifying the viewer U1.
Further, the receiver 60 may fetch the viewer identification information from the communication-connected terminal device 90 and set the viewer identification device as its own device for use.

  As the viewer identification information, information for identifying a single viewer may be used, or information for identifying a group composed of a plurality of viewers may be used. This group is, for example, a family or a plurality of friends.

  Each time the receiver 60 is operated, the receiver 60 additionally registers information specifying the operation and information indicating the operation date and time in the receiver operation history information. The receiver 60 supplies the viewer identification information and the receiver operation history information to the service server group 40 regularly or at a predetermined time.

The receiver 60 takes in the personal advertising content data selected and supplied by the service server group 40 based on the viewer identification information and the receiver operation history information. Then, the receiver 60 reproduces the program content data and the personal advertising content data in association with each other.
The receiver 60 is realized by, for example, a television receiver, a set top box, a computer device, a portable terminal, or the like.

The terminal device 90 can operate in conjunction with the receiver 60 by connecting to the receiver 60.
The terminal device 90 stores viewer identification information. This viewer identification information is information for identifying a user who uses the device, and is, for example, device identification information unique to the terminal device 90. Alternatively, the viewer identification information is arbitrary identification information set in the terminal device 90 by the user. For example, in FIG. 1, the user of the terminal device 90 is the viewer U3, and the viewer identification information stored in the terminal device 90 is information for identifying the viewer U3.

  The terminal device 90 additionally registers information indicating the contents used and information indicating the use date and time in the terminal use history information. The terminal device 90 supplies viewer identification information and terminal usage history information to the service server group 40 periodically or at a predetermined time or whenever it is used.

  The terminal device 90 takes in the personal advertising content data selected and supplied by the service server group 40 based on the viewer identification information and the terminal usage history information. Then, the terminal device 90 reproduces the personal advertising content data.

  In the broadcasting / communication cooperation service, the receiver 60 controls a display area (program area) for program content data and a display area (application area) for applications and distribution content data. The receiver 60 also controls audio output of program content data and audio output of applications and distribution content data. Specifically, the receiver 60 may display the program content data and the distribution content data and the audio output method (hereinafter, both methods may be referred to as output methods) for each broadcast program or asynchronously with the broadcast program. ) To control.

As a display method, for example, only the program area is displayed, the program area and the application area are displayed in an entirely or partially overlapped manner, or the program area and the application area are independently displayed without being overlapped. is there.
As an audio output method, there are methods such as outputting only the audio of the program content data, or outputting the audio of the program content data and the audio of the application and distribution content data independently or mixed.

  A display method and an audio output method requested by the broadcaster to the receiver 60 are defined as a policy. The policy has a plurality of stages depending on the importance of the contents of the program content data, the production, etc., and these stages are called policy levels. That is, the policy level indicates a level for restricting the display and audio output of the application with respect to the display and audio output of the program content data, and is represented by an integer value, for example. For example, a high policy level indicates that the level of application display and audio output restriction is high (strict regulation). For example, when it is desired to preferentially display broadcast program content data with high urgency or importance, the broadcast station sets a high policy level for the program content data.

Next, the relationship between the policy level and the display method will be described as an example where the policy level is expressed by four levels from “4” to “1”.
First, when the policy level is “4”, the receiver 60 can only display the full screen of the program content data.
When the policy level is “3”, the receiver 60 can display the broadcaster-provided application and the certified application. However, all applications are prohibited from being superimposed on the program content data, and can only be displayed outside the program content.
When the policy level is “2”, the receiver 60 can display the broadcaster-provided application and the certified application. However, only the broadcaster-provided application can be overlaid on the program content. For applications other than broadcaster-provided applications, overlay display on the program content is prohibited, and only display outside the program content is possible.
When the policy level is “1”, the receiver 60 can display the broadcaster-provided application and the certified application. The broadcast provider-provided application and the certified application can be superimposed on the program content.

The voice output method for each policy level is, for example, as follows.
That is, when the policy level is “4” or “3”, the receiver 60 can output audio only for program content data.
When the policy level is “2”, the receiver 60 can output sound only from the broadcaster-provided application. However, the receiver 60 outputs the audio of the program content data and the distribution content data independently by switching.
When the policy level is “1”, the receiver 60 can output the audio of the broadcaster-provided application and the audio of the authorized application. However, the receiver 60 independently outputs the program content data and the sound of each application by switching for both the broadcaster-provided application and the certified application.

The feature word is one or more keywords that match or relate to the content of the advertisement content data.

Next, the configuration of the broadcast station apparatus group 10 will be described.
FIG. 9 is a block diagram showing a schematic functional configuration of the broadcast station apparatus group 10. As shown in the figure, the broadcast station apparatus group 10 includes a broadcast facility 11 and a broadcast station service server (broadcast station apparatus) 12.
The broadcast facility 11 is a facility for transmitting a digital broadcast signal to the transmission antenna 20. Specifically, the broadcasting facility 11 includes a program organization device 111, a program transmission device 112, and a transmission device 113.

The program organizing device 111 generates a stream in which various control information related to the program content is multiplexed with the program content produced by a broadcasting station, a program production company, or the like. When the stream is a TS, the various control information is, for example, an event information table (Event Information Table; EIT), an application information table (Application Information Table; AIT), application presentation control information, and the like. The EIT includes meta information related to the program content, such as the program content name (title), broadcast date and time, genre, and description (summary). AIT (also referred to as application management information) is management information relating to one or more applications executed by the receiver 60. The AIT includes, for each application, application identification information for identifying the application, location information (for example, URL information) indicating the location of the application on the network, and the like. The application presentation control information is data indicating how to control the output method of program content data and distribution content data in accordance with a program being broadcast, an event included in a broadcast signal, an application provider, and the like. The application presentation control information is information indicating the policy level described above, for example. The personal advertisement presentation application is a broadcaster-provided application, and the application area overlaps to include the program area. Therefore, the policy level is “2” or “1”.
The program organization device 111 supplies the generated stream to the program transmission device 112.

Further, the program organizing apparatus 111 supplies the program guide data produced by the broadcasting station, the broadcaster-provided application, and the distribution content data to the broadcasting station service server 12.
In addition, the program organization device 111 supplies the advertisement control information created by the broadcast station to the broadcast station service server 12.

  The program transmission device 112 takes in the stream supplied from the program organization device 111. When the stream is a stream of program content, the program transmission device 112 supplies the stream to the transmission device 113 according to the broadcast schedule. Further, when the stream is an emergency content stream, the program transmission apparatus 112 supplies the stream to the transmission apparatus 113 by an event message transmission method, for example.

  For example, when broadcasting emergency content, the program transmission device 112 generates an emergency erasure signal (emergency release signal), multiplexes it into a stream, and supplies this stream to the transmission device 113. The emergency erasure signal is a signal for causing the receiver 60 that is executing the personal advertisement presentation application to stop displaying personal advertisement content data and outputting sound.

  For example, there are the following two examples of signal areas for multiplexing the emergency erasure signal. As a first example, the program transmission device 112 multiplexes an emergency erasure signal on an auxiliary channel (AC) that is a transmission path for additional information related to broadcasting. As a second example, the program transmission device 112 multiplexes an emergency erasure signal with a Transmission and Multiplexing Configuration Control (TMCC) signal that is a transmission control signal.

  The transmission device 113 takes in the stream supplied from the program transmission device 112, converts this stream into a broadcast signal, and supplies it to the transmission antenna 20.
