(Example of receiver configuration)
FIG. 4 is a diagram showing a configuration example of the receiver 5000 of the first embodiment. As shown in FIG. 4, the receiver 5000 has a communication content processing unit 5100 and a broadcast content processing unit 5300. The communication content processing unit 5100 has a hybrid cast specification connected to a network. The connection destination of the network is, for example, the above-mentioned management server 3000. The broadcast content processing unit 5300 receives the broadcast wave.

The communication content processing unit 5100 includes an IP communication interface 5101. The stream taken in via the IP communication interface 5101 is received by the streaming reception processing unit 5102, and the demodulated stream is restored to the original array state by the demultiplexer 5303. A DRAM processing unit 5104 is connected to the demultiplexer 5303, and the DRAM processing unit 5104 can operate a program to execute, for example, automatic download.

The video stream separated by the demultiplexer 5303 is decoded by the video decoder 5311, the audio stream is decoded by the audio decoder 5312, and the subtitle stream is decoded by the subtitle decoder 5313.

The decoded video data and subtitle data are combined by the synthesizer 5501 and input to the display 5002. The decoded voice data is input to the speaker unit 5003.

The broadcast content processing unit 5300 includes a broadcast tuner 5301. The stream received and demodulated by the broadcast tuner 5301 is input to the descrambler 5302. In the descrambler 5302, the input stream is descrambled with the key from the CAS (Conditional Access System) module 5304. The stream descrambled by the descrambler 5302 is input to the demultiplexer 5303.

The demultiplexer 5303 outputs data for data broadcasting to the data broadcasting reception processing unit 5330. Further, the video stream separated by the demultiplexer 5303 is decoded by the video decoder 5311, the audio stream is decoded by the audio decoder 5312, and the subtitle stream is decoded by the subtitle decoder 5313. The decoded video data and subtitle data are combined by the synthesizer 5501 and input to the display 5002. The decoded voice data is input to the speaker system 5003.

The addressable CM owned by the CM distribution server 4000 is divided into a plurality of groups tagged with "car", "sports", "travel", etc., which represent the tastes of viewers. The integrated controller 5200 downloads an addressable CM group to which a tag suitable for the viewer's preference is attached based on the information regarding the viewer's preference of the receiver 5000 acquired from the management server 3000.

The addressable CM downloaded to the recording medium 5001 is temporarily stored in the DRAM processing unit 5104. After that, the addressable CM is separated by the demultiplexer 5303, the video stream is decoded by the video decoder 5311, the audio stream is decoded by the audio decoder 5312, and the subtitle stream is decoded by the subtitle decoder 5313.

The decoded video data and subtitle data are combined by the synthesizer 5501 and input to the display 5002. The decoded voice data is input to the speaker system 5003 via the synthesizer 5502. As a result, the addressable CM is output by the display 5002 and the speaker system 5003.

The application control unit 5201 controls each block of the receiver 5000 based on the application control information regarding the reproduction of the addressable CM, and reproduces the addressable CM in a predetermined addressable CM frame.

(Management server configuration example)
FIG. 5 is a hardware configuration diagram of the management server 3000. As shown in FIG. 5, the management server 3000 has a CPU (Center Processing Unit) 3051, a ROM (Read Only Memory) 3052, a RAM (Random Access Memory) 3053, a storage unit 3054, and a communication unit 3055.

The storage unit 3054 is a storage unit such as an HDD or SSD. The storage unit 3054 stores a preference analysis program described later. By operating based on this preference analysis program, the CPU 3051 analyzes the preferences of the viewer and notifies the CM distribution server 4000 of the analysis result (preference analysis information). As a result, the addressable CM that matches the taste of the viewer is delivered to the receiver 5000 of the viewer, inserted between programs, and reproduced.

(Management server function)
FIG. 6 is a functional block diagram of each function realized by the CPU 3051 of the management server 3000 executing the preference analysis program. By executing the preference analysis program, the CPU 3051 realizes the functions of the storage control unit 3100, the analysis unit 3200, the communication control unit 3300, and the voice recognition unit 3400, as shown in FIG.

The storage unit 3100 stores the viewing history of the receiver 5000 managed by the management server 3000. The viewing history includes, for example, a program title, a program ID, a program outline, performers, a broadcast date and time, and other data.

Further, the storage control unit 3100 stores and reproduces the viewing history, playback history, recording setting, viewing reservation setting, etc. received from the receiver 5000 with respect to the storage unit 3054. Further, the storage control unit 3100 stores and reproduces the preference information acquired from the viewer's external device 6000 to the storage unit 3054.

Further, in the broadcasting system of the embodiment, the receiver 5000 and the like can be operated by voice by the voice operation device 7000. The management server 3000 recognizes the operation voice acquired from the voice operation device 7000 by the voice recognition unit 3400 and transmits the operation voice to the receiver 5000, thereby enabling the voice operation of the receiver 5000. The storage control unit 3100 stores and reproduces the operation history information corresponding to the operation voice for the receiver 5000 and the like acquired from the voice operation device 7000 to the storage unit 3054.

The analysis unit 3200 analyzes the viewer's preference and the like from the viewing history and the attribute information of the viewer of the receiver 5000 managed by the management server 3000. The attribute information of the viewer is information obtained from the viewer by a questionnaire survey or the like in advance (for example, when purchasing a receiver). The attribute information of the viewer includes, for example, gender information and generation information about the members of the household.

From this information, for example, the preference of the viewer of the receiver 5000 managed by the management server 3000 is estimated. For example, information such as car lovers, sports lovers, and travel lovers can be obtained from the viewing tendency of viewers.

Further, for example, in a broadcast program "a" targeting the target layer "Y", a commercial for a product "n" that matches the taste of the target layer "Y" is flowing, and a target interested in the product "m". It is assumed that the viewer belonging to the layer "X" is also found to be watching the broadcast program "a".

In this case, for example, the analysis unit 3200 sets the CM frame for the product "n" in the addressable CM frame, and provides the addressable CM for the product "m" to the viewers belonging to the target layer "X". It may be determined that it is suitable for.

In addition to this, we have set an addressable CM frame for broadcast programs in the night time zone that parents are likely to be watching for parents of households with children, and addressable products related to children. It is conceivable to provide a commercial.

The communication control unit 3300 notifies the broadcasting station 1000 of these analysis results by the analysis unit 3200, for example. These analysis results are acquired by the advertising company AD via the broadcasting station 1000, and the addressable CM frame is purchased by the advertiser MC of the target product.

Further, the communication control unit 3300 notifies the broadcasting station 1000 of, for example, the distribution record when the addressable CM is actually distributed in the purchased addressable CM frame. These distribution results are reported to the advertising company AD and the advertiser MC via the broadcasting station 1000.

Further, the communication control unit 3300 notifies the receiver 5000 of the taste of the viewer analyzed by the analysis unit 3200. As a result, when the receiver 5000 acquires the addressable CM from the CM distribution server 4000, the receiver 5000 can selectively acquire the addressable CM that suits the taste of the viewer.

Further, as will be described later, the communication control unit 3300 transmits a CM list for selecting the CM desired by the viewer to the viewer's external device 6000 and the receiver 5000. This CM list is a list of CM names and the like. The viewer selects the CM to be distributed from this list and designates it as the management server 3000. The communication control unit uses the CM distribution server for information indicating the CM designated by the viewer and the preference analysis information indicating the viewer's preference analyzed based on the CM specified by the viewer by the analysis unit 3200. Send to 4000.

(Hardware configuration of external device)
FIG. 7 is a diagram showing a hardware configuration of the external device 6000. As shown in FIG. 7, the external device 6000 has a CPU 6031, a ROM 6032, a RAM 6033, a timer 6034, a storage unit 6035, a communication unit 6036, a display unit 6037, an operation unit 6038, a speaker unit 6039, and a microphone unit 6040. There is.

The storage unit 6035 stores the oriented providing application program. As will be described in detail later, the CPU 6031 notifies the management server 3000 of the preference information indicating the viewer's preference based on this oriented providing application program. As a result, the CM that matches the taste of the viewer is distributed from the management server 3000 via the CM distribution server 4000.

Further, the storage unit 6035 stores image data captured by the user or acquired via a network. When the viewer specifies a desired image among the images shown in the image data, the viewer's preference is analyzed from the image specified by the management server 3000, and the CM distribution server 4000 determines the viewer's preference. Matching CMs are being delivered.

The voice operation device 7000 also has a hardware configuration similar to the hardware configuration shown in FIG. 7. In the case of the voice operation device 7000, the operation sound from the viewer is collected by the microphone unit 6040 and transmitted to the management server device 3000.

(Reproduction of addressable CM)
FIG. 8 is a timing chart at the time of addressable CM reproduction in the broadcasting system of the first embodiment. In the example of FIG. 8, it is assumed that the addressable CM that matches the taste of the viewer of the receiver 5000 has already been downloaded to the recording medium 5001. Alternatively, during the broadcast program, the addressable CM that suits the taste of the viewer may be downloaded to the recording medium 5001 by asynchronous communication or the like.

As shown in FIG. 8, in the broadcasting system of the first embodiment, when the main part of the broadcast program is started, the hybrid cast application related to the reproduction of the addressable CM is started. The hybridcast application is launched but controlled to be hidden.

Specifically, the technical specifications of the hybrid cast are standardized as the technical specifications of the IPTV forum and the standards of ARIB (Association of Radio Industries and Businesses). In the ARIB standard, when a PMT (Program Map Table) included in a broadcast signal is received, the receiver 5000 receives BML (Broadcast Markup Language), which is data broadcasting content, based on the PID (Packet ID) described in the PMT. ) Content is launched. In the initial state, the application control information is acquired from the server device on the network by the script described in the BML contents. After acquisition, the hybrid cast application is started according to the acquired application control information.

When the event message EM1 included in the broadcast signal and announcing the start of the CM is received, the hybrid cast application displays a predetermined screen over the broadcast video. At this time, in the hybrid cast application, the application control unit 5201 controls the display of the graphics from the non-display state to the display state. That is, when the hybrid cast application is started, it is controlled to be hidden, and when the event message EM1 is received, the hybrid cast application screen is displayed in a transparent state. Therefore, it does not interfere with the viewing of the main program. In a hybrid cast application, such interrupt display and overlay display are possible under predetermined conditions. The event message EM1 is included in the broadcast signal and transmitted from the broadcasting station 1000 before a predetermined time (for example, 1 second to several seconds before) of the CM start time.

The hybrid cast application screen may be displayed not only in a transparent state but also in a semi-transparent state. Even in this case, the main part of the program is not completely hidden, and the viewing of the main part of the program is not hindered. At this time, auxiliary information such as a predetermined message or mark may be displayed for the viewer in a corner of the screen or the like.

The hybrid cast application starts playing the downloaded addressable CM when the event message EM2 indicating the start of the CM included in the broadcast signal is received. Immediately after the reproduction of the addressable CM is completed, the event message EM3 indicating the end of the CM included in the broadcast signal is received. Since the length of the addressable CM is set according to the length of the addressable CM frame, the reproduction of the addressable CM ends immediately before the reception of the event message EM3.

(Example of receiver display screen)
Next, FIG. 9 is an example of a display screen displayed on the display 5002 by the receiver 5000. The display screen shown in FIG. 9 is displayed prior to downloading the addressable CM to the recording medium 5001 of the receiver 5000.

As shown in FIG. 9, when the integrated controller 5200 downloads the addressable CM from the CM distribution server 4000 to the recording medium 5001 of the receiver 5000, the integrated controller 5200 requests the viewer of the receiver 5000 to use the recording medium 5001. Display a message. The content of the message is not limited to the license agreement, but a message asking for a specific usage amount such as "how many GB will be used" may be displayed. Thereby, it can be shown that the recording medium 5001 owned by the viewer is not used without permission, and it is possible to show how much the capacity of the recording medium 5001 is used. The addressable CM is downloaded at an arbitrary timing when the recording medium 5001 is not used after the permission of the viewer is obtained.

FIG. 10 is an example of a screen displayed on the display 5002 by the receiver 5000 when the addressable CM is reproduced. As shown in FIG. 10, when the receiver 5000 receives the event message EM1 indicating that the CM is about to start, the hybrid cast application superimposes the broadcast video on the message as auxiliary information indicating that the CM is replaced. Alternatively, a semi-transparent screen SCa including a mark or the like may be displayed. Make it easier to see messages or marks by displaying them semi-transparently instead of transparently. As a result, the viewer can know that the addressable CM is started, and can indicate in advance that the CM (advertisement) is of interest to the viewer, so that the viewer is more interested than the normal CM. Watch with.

FIG. 11 is another example of the screen displayed on the display 5002 by the receiver 5000 when the addressable CM is reproduced. As shown in FIG. 11, when the receiver 5000 receives the event message EM2 indicating the start of CM, the hybrid cast application arranges the moving image SCb of the addressable CM in the screen SCa and displays and reproduces it. At this time, a message during CM replacement may be displayed on the screen SCa. The moving image SCb of the addressable CM is displayed in an area smaller than the screen SCa, for example, with respect to the screen SCa displayed on the full screen. Therefore, the message during CM replacement is not hidden and continues to be displayed as it is. As a result, it is possible to show the viewer that the CM is an addressable CM even in the addressable CM, and it is possible to make the viewer interested.

In addition, regardless of the example of FIG. 11, the moving image SCb of the addressable CM may be displayed in full screen. Further, at this time, the message during CM replacement may be displayed in the moving image SCb of the addressable CM, or may be hidden. That is, even when the video SCb of the addressable CM is displayed in full screen, the message during CM replacement may be displayed in the frame of the video SCb.

The hybrid cast application hides the screen SCa and the moving image SCb at the end of the reproduction of the addressable CM, and returns the display of the display 5002 to the screen of the original broadcast moving image.

(Display processing in receiver)
FIG. 12 is a flow chart showing an example of a procedure for displaying an addressable CM in the receiver 5000.

As shown in FIG. 12, when the main part of the broadcast program is started and the receiver 5000 receives the PMT included in the broadcast signal (step S101), the application control unit 5201 starts the hybrid cast application and hides it (step S101). S102). The hybrid cast application waits for the reception of the event message EM1 foretelling the start of the CM (step S103: No).

When the receiver 5000 receives the event message EM1 (step S103: Yes), the hybrid cast application displays the application screen by the hybrid cast application. That is, the non-display state is changed to the display state (step S104). The application screen may be a transparent screen or a screen SCa including a message to replace the CM.
