(Management server configuration example)
FIG. 5 is a diagram showing a configuration example of the management server 3000 according to the first embodiment. As shown in FIG. 5, the management server 3000 includes a storage unit 3100, an analysis unit 3200, and a notification unit 3300.

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.

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 notification 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 notification 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 notification 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.

(Reproduction of addressable CM)
FIG. 6 is a timing chart at the time of addressable CM reproduction in the system according to the first embodiment. In the example of FIG. 6, 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, it may be downloaded to the recording medium 5001 by asynchronous communication or the like during a broadcast program.

As shown in FIG. 6, in the 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 standard of ARIB (Association of Radio Industries and Businesses). According to the ARIB standard, when a PMT (Program Map Table) included in a broadcast signal is received, the receiver 5000 receives a BML (Broadcast Markup Language) which is a data broadcast content based on the PID (Packet ID) described in the PMT. ) Content is launched. In the initial state, the application control information on the server on the network is acquired by the script described in the BML contents. After that, 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 commercials for the general public is received, the hybrid cast application displays a predetermined screen superimposed on 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 in a corner of the screen for the viewer.

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.

Next, the screen displayed by the receiver 5000 on the display 5002 will be described.

FIG. 7 is an example of a screen displayed on the display 5002 by the receiver 5000 according to the first embodiment. The screen of FIG. 7 is displayed prior to downloading the addressable CM to the recording medium 5001 of the receiver 5000.

As shown in FIG. 7, 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 message requesting the viewer of the receiver 5000 to use the recording medium 5001. Is displayed. Further, as the content of the message, not only the license but also a specific usage amount such as "how many GB will be used" may be displayed as a message. 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. 8 is an example of a screen displayed on the display 5002 when the receiver 5000 according to the first embodiment reproduces the addressable CM. As shown in FIG. 8, 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 to be replaced. 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. 9 is another example of the screen displayed on the display 5002 when the receiver 5000 according to the first embodiment reproduces the addressable CM. As shown in FIG. 9, 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.

However, regardless of the example of FIG. 9, the moving image SCb of the addressable CM may be displayed in full screen. At this time, the message being replaced may be displayed in the moving image SCb of the addressable CM, or may be hidden. That is, even when the moving image SCb of the addressable CM is displayed in full screen, the message during CM replacement may be displayed in the frame of the moving image 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. 10 is a flow chart showing an example of a procedure for displaying an addressable CM in the receiver 5000 according to the first embodiment.

As shown in FIG. 10, 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. Then, the hybrid cast application waits for the reception of the event message EM2 indicating the start of the CM (step S105: No).

When the receiver 5000 receives the event message EM2 (step S105: Yes), the hybrid cast application displays the video SCb of the addressable CM on the transparent screen or the screen SCa, and starts playing the addressable CM (step S106). .. After the lapse of a predetermined time, the hybrid cast application ends the reproduction of the addressable CM (step S107). The hybrid cast application then hides the moving image SCb (screen SCa and). That is, the display state is changed to the non-display state (step S108). The hybrid cast application waits for the reception of the event message EM3 indicating the end of the CM (step S109: No).

When the receiver 5000 receives the event message EM3 (step S109: Yes), the display process of the addressable CM in the receiver 5000 ends.

In recent years, the viewing history of contents via television and the Internet has been collected, and the tastes and purchasing behaviors of viewers have been analyzed. As one means of utilizing such analysis results, there is a need for addressable commercial distribution to specific viewers. However, it has been difficult to replace the addressable CM with the CM frame in a normal broadcast program and display the switch.

In the receiver 5000 of the first embodiment, the hybrid cast application appropriately displays a screen regarding the addressable CM according to the event messages EM1 to EM3 included in the broadcast signal. As a result, the addressable CM can be displayed and reproduced in place of the CM by broadcasting.

In the receiver 5000 of the first embodiment, the hybrid cast application is started in advance by the application control unit 5201 and is controlled to be hidden. By being activated in advance, it is possible to start the reproduction of the addressable CM at a quick timing in accordance with the start of the addressable CM frame.

In the receiver 5000 of the first embodiment, when switching from the broadcast moving image, the hybrid cast application displays, for example, a screen SCa including a message to replace the CM. As a result, the time lag that may occur when switching from the broadcast video can be filled, and the screen can be smoothly transitioned to the addressable CM video without making the viewer feel uncomfortable.

(Modification example)
11 to 13 are examples of screens displayed on the display when the receiver according to the modified example of the first embodiment reproduces the addressable CM.

As shown in FIG. 11, in the receiver of the modified example, the hybrid cast application is playing the addressable CM in the margin of the screen SCc displayed on the broadcast video, that is, in the outer frame of the video SCb of the addressable CM. Auxiliary information such as a mark MKa indicating the target viewer of the above may be displayed. As a result, in the example of FIG. 11, the viewer can immediately notice the "car-related" commercial.

As shown in FIG. 12, in the receiver of the modified example, the hybrid cast application adds information such as the mark MKa of the addressable CM currently being played to the margin of the screen SCd displayed overlaid on the broadcast video, or Instead, information such as a mark MKb indicating a target viewer of the addressable CM to be reproduced next may be displayed. The information indicating the addressable CM to be reproduced next may be a thumbnail or the like. As a result, in the example of FIG. 12, the viewer knows in advance that the "baseball-related" CM will be displayed next from the "car-related" CM (advance notice of the CM), so that the viewer can be more informed. It can be interesting.

As shown in FIG. 13, in the receiver of the modified example, the hybrid cast application displays the colors and patterns of the screens SCe and SCf superimposed on the broadcast video according to the age group of the target viewers of the addressable CM. You may change the texture and the like. The screen of FIG. 13A is an example of the screen SCe of the addressable CM for the elderly. The screen of FIG. 13B is an example of the screen SCf of the addressable CM for young people. Since the visibility changes depending on the color of the screen depending on the age of the viewer, the addressable CM can be made easier to see by changing the screen. Also, when changing the screen, the viewer can be made to select the screen SCe or SCf.

[Embodiment 2]
Hereinafter, the second embodiment will be described in detail with reference to the drawings. The system of the second embodiment has the same configuration as the system of the first embodiment. In the following description, FIGS. 4 and the like will be referred to, and the same reference numerals will be given to the configurations corresponding to the configurations of the first embodiment.

The second embodiment is an example in which the broadcast signal does not include an event message.

(Reproduction of addressable CM)
FIG. 14 is a timing chart at the time of addressable CM reproduction in the system according to the second embodiment. In the example of FIG. 14, the management server 3000 notifies the receiver 5000 in advance of the predetermined time of the addressable CM frame in the predetermined broadcast program notified from the broadcasting station 1000. The hybrid cast application of the receiver 5000 replaces and displays the addressable CM based on the predetermined time notified from the management server 3000.

As shown in FIG. 14, when the main part of the broadcast program is started and the receiver 5000 receives the PMT included in the broadcast signal, the application control unit 5201 starts the hybrid cast application. At this time, as in the embodiment, the hybrid cast application is hidden.
