The acquisition unit 5100 may acquire the addressable CM frame information 91 from the distribution data of the IP broadcast transmitted by the Internet.

The requesting unit 5200 requests the CM distribution server 4000 to play an addressable CM in the CM frame registered in the addressable CM frame information 91. More specifically, the requesting unit 5200 determines the receiver ID, the CM frame ID registered in the addressable CM frame information 91, and the conditions of the addressable CM that can be reproduced in the CM frame specified by the CM frame ID. It is associated and transmitted to the CM distribution server 4000. The condition of the addressable CM that can be reproduced in the CM frame registered in the addressable CM frame information 91 is, for example, the genre of the broadcastable CM registered in the addressable CM frame information 91.

The receiving unit 5300 receives from the CM distribution server 4000 a variable-length addressable CM or a fixed-length addressable CM that can be reproduced in the CM frame specified by the CM frame ID registered in the addressable CM frame information 91. More specifically, the receiving unit 5300 includes video data of the addressable CM that satisfies the conditions transmitted by the requesting unit 5200, attribute information 92 of the addressable CM, division position information 93 of the addressable CM, and frame information 94 for still images. And receive. The receiving unit 5300 stores the received moving image data of various addressable CMs, the attribute information 92 of the addressable CMs, the division position information 93 of the addressable CMs, and the frame information 94 for still images in the storage unit 5800. The still image frame information 94 is not essential.

The editorial unit 5400 edits the variable length addressable CM according to the time length of the CM frame included in the addressable CM frame information 91. More specifically, the editorial unit 5400 extracts a portion to be reproduced from the variable length addressable CM based on the divided position information 93 of the addressable CM described with reference to FIGS. 8 and 9.

Further, the editorial unit 5400 has the same time length of the CM frame registered in the addressable CM frame information 91 by combining one or a plurality of variable length addressable CMs or one or a plurality of fixed length addressable CMs. Organize a combination of addressable CMs with a long playback time. The combination of addressable commercials is an example of the advertising content group in the present embodiment.

More specifically, the editorial unit 5400 is an addressable CM of a genre that can be broadcast in the CM frame for each CM frame registered in the addressable CM frame information 91, and corresponds to the broadcastable frame of the attribute information 92 of the addressable CM. Combine a plurality of addressable CMs in which the CM frame ID of the CM frame is registered.

FIG. 11 is a diagram showing an example of the combination 50a of the addressable CM according to the present embodiment. The combination 50a of the addressable CM shown in FIG. 11 is the combination 50a of the addressable CM reproduced by the CM frame ID “AD1” shown in FIG. In the attribute information 92 of the addressable CM, "AD1" is registered in the broadcastable frame in two, an addressable CM having a CMID of "1" and an addressable CM having a CMID of "2". Further, since the genres of the addressable CM having a CMID of "1" and the addressable CM having a CMID of "2" are the genres of CMs that can be broadcast by the CM frame ID "AD1", these two addressable CMs are CMs. It can be played back with the frame ID "AD1".

In the example shown in FIG. 11, the editorial unit 5400 has an addressable CM having a CMID of "1" (displayed as "CM1" in FIG. 11) and an addressable CM having a CMID of "1" (displayed as "CM2" in FIG. 11). And are combined so as to be played alternately.

The time length of the CM frame ID "AD1" is 180 seconds, the total time length of the addressable CM having the CMID "1" is 30 seconds, and the CM length of the addressable CM having the CMID "2" is 25 seconds. In this case, there will be a margin of 15 seconds at the end. Here, since the addressable CM having a CMID of "1" has a variable length, the editorial unit 5400 changes the time length of the addressable CM having a CMID of "1" to 15 seconds, and at the end of the addressable CM combination 50a. to add. For example, the editorial unit 5400 searches for a CM length having the same time length as the time length of the margin from the divided position information 93 of the addressable CM, and based on the start time and end time associated with the time length, the CMID. Extracts video data having the same time length as the margin time length from the video data of the addressable CM of "1". As a result, the total reproduction time of the addressable CM combination 50a is 180 seconds, which is the same as the time length of the CM frame ID “AD1”.

Further, when there are a plurality of addressable CMs that can be reproduced in one CM frame, the editorial unit 5400 combines the addressable CMs so that the addressable CMs having the longest CM length are reproduced first. When the remaining time of the CM frame is short, it becomes difficult to reproduce an addressable CM having a long CM length. Therefore, the editorial unit 5400 secures a reproduction opportunity of the addressable CM having a long CM length by reproducing the addressable CM having a long CM length first.

FIG. 12 is a diagram showing another example of the addressable CM combination 50b according to the present embodiment. Hereinafter, when the combination 50a of the addressable CM and the combination 50b of the addressable CM are not particularly distinguished, it is simply referred to as the combination 50 of the addressable CM.

When the combination 50b of the addressable CM is shorter than the time length of the CM frame, the editorial unit 5400 adds a still image to the end of the combination 50b of the addressable CM. In the example shown in FIG. 12, the total reproduction time of the combination of the addressable CM1 of 30 seconds, the addressable CM2 of 25 seconds, and the addressable CMn of 13 seconds is 2 seconds shorter than the time length of the CM frame ID “AD1”. Further, it is assumed that the addressable CM having a time length of 2 seconds is not stored in the storage unit 5800.

In this case, the editorial unit 5400 identifies the position of the still image frame in the addressable CM based on the still image frame information 94 stored in the storage unit 5800, and uses the still image frame as the combination 50b of the addressable CM. Add to the end. The editorial unit 5400 may, for example, extract a still image frame from the last reproduced addressable CM.

Further, the editorial unit 5400 may add a still image only when the difference between the time length of the CM frame and the total reproduction time of the addressable CM combination 50b is equal to or less than a predetermined time length. The predetermined time length is, for example, 3 seconds.

Further, the editorial unit 5400 may combine a plurality of still images instead of one still image. Further, the editorial unit 5400 may combine a message indicating that the still image is an advertisement, a logo, an illustration, or the like on the screen of the still image. The message, logo, illustration, or the like to be combined on the screen of the still image may be a dynamically changing image.

Further, the editorial unit 5400 may extract a frame other than the frame defined in the still image frame information 94 as a still image. For example, the editorial unit 5400 identifies a frame in which characters such as a product name are displayed or a frame in which a person's face is displayed from the video data of the addressable CM by image processing, and sets the specified frame as the addressable CM. May be added to the combination 50b of. Further, the editorial unit 5400 may extract as a still image the frame closest to the end of the video data of the addressable CM among the frames whose entire screen is not white or black included in the video data of the addressable CM. Further, the additional position of the still image may be other than the end of the addressable CM combination 50b.

Further, the editorial unit 5400 may add the image data of the still image to the combination 50b of the addressable CM instead of the frame of the moving image data of the addressable CM. As an example, the image data of the still image may be an image displaying a QR code (registered trademark), a URL, or the like. The QR code (registered trademark), URL, etc. shall be connected to, for example, the website of the provider of the addressable CM or other link destinations. By using these QR codes (registered trademarks) or URLs, the viewer can notify the provider of the addressable CM that he / she has viewed the addressable CM.

Further, the editorial unit 5400 may add short moving image data of about 2 to 3 seconds instead of a still image to the addressable CM combination 50b. The image data or short moving image data of these still images may be stored in advance in the storage unit 5800, or may be transmitted from the CM distribution server 4000 or the management server 3000 to the receiver 5000.

Further, the editorial unit 5400 converts audio data such as music and narration into the addressable CM combination 50 so that music and narration can be played during the time when the image data of the still image or the short moving image data is displayed. It may be associated. These voice data such as music and narration may be stored in advance in the storage unit 5800, or may be transmitted from the CM distribution server 4000 or the management server 3000 to the receiver 5000. Further, the editorial unit 5400 does not have to associate audio data with the time so that the image data of the still image or the short moving image data is silent during the time. The editorial unit 5400 may determine whether to mute or play sound based on the content of the image data of the still image or the short moving image data, the genre of the addressable CM played immediately before, and the like.

Further, the editorial unit 5400 shall organize the addressable CM combination 50 at any time during the broadcast time of the CM frame for reproducing the addressable CM combination 50. In this case, each time the editorial unit 5400 determines the addressable CM to be reproduced from the beginning of the addressable CM combination 50, the editorial unit 5400 obtains the CM frame ID and the CMID or detailed ID of the addressable CM included in the addressable CM combination 50. It is associated and transmitted to the reproduction control unit 5500. Further, if the acquisition unit 5100 has acquired the addressable CM frame information 91 and the like in advance before the start of the broadcast time of the CM frame, the editorial unit 5400 may combine the addressable CM before the start of the broadcast time of the CM frame. 50 may be organized. In this case, the editorial unit 5400 transmits the CM frame ID and the CMID or detailed ID of the addressable CM included in the organized addressable CM combination 50 to the reproduction control unit 5500 in association with each other.

Further, the editorial unit 5400 can change the CM length of any of the fixed length addressable CMs to the same time length as the CM frame, or change the CM length of the variable length addressable CM to the same time length as the CM frame. In some cases, one addressable CM may be selected as a reproduction target without combining a plurality of addressable CMs.

Returning to FIG. 5, the reproduction control unit 5500 reproduces the addressable CM combination 50 at the broadcast time of the CM frame registered in the addressable CM frame information 91. Further, the reproduction control unit 5500 associates the CMID of the reproduced addressable CM with the reproduced position and stores the CM reproduction record information in the storage unit 5800. Further, the reproduction control unit 5500 may store not only the reproduction record of the addressable CM but also the broadcast record of the normal CM as the CM reproduction record information. Further, the reproduction control unit 5500 may also store the viewing history of the broadcast program viewed by the viewer on the receiver 5000 in the storage unit 5800.

The transmission unit 5600 periodically transmits the CM reproduction record information stored in the storage unit 5800 to the management server 3000 in association with the receiver ID. Further, the transmission unit 5600 may transmit the reproduction record by the reproduction control unit 5500 to the management server 3000 each time. Further, the transmission unit 5600 may further transmit the viewing history of the broadcast program viewed by the viewer on the receiver 5000 to the management server 3000.

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.

(Reproduction processing of addressable CM)
Next, the flow of the reproduction processing of the addressable CM in the transmission / reception system S configured as described above will be described.

FIG. 15 is a sequence diagram showing an example of the flow of the reproduction processing of the addressable CM according to the present embodiment.

First, the broadcasting station 1000 transmits the addressable CM frame information 91 to the receiver 5000 by a broadcast wave (S1). The acquisition unit 5100 of the receiver 5000 acquires the addressable CM frame information 91 from the broadcast wave and stores it in the storage unit 5800.

Then, the request unit 5200 of the receiver 5000 requests the CM distribution server 4000 to play an addressable CM in the CM frame registered in the addressable CM frame information 91 (S2). The receiving unit 4200 of the CM distribution server 4000 receives the request transmitted from the receiver 5000. Further, the search unit 4300 of the CM distribution server 4000 searches for an addressable CM that satisfies the request transmitted from the receiver 5000.

Next, the transmission unit 4400 of the CM distribution server 4000 transmits the addressable CM searched by the search unit 4300 to the receiver 5000 (S3). That is, the transmission unit 4400 transmits the attribute information of the addressable CM satisfying the conditions, the division position information of the addressable CM, and the moving image data of the addressable CM to the receiver 5000. Then, the receiving unit 5300 of the receiver 5000 uses the video data of the addressable CM transmitted by the requesting unit 5200, the attribute information 92 of the addressable CM, and the divided position information 93 of the addressable CM as a CM distribution server. Receive from 4000.

Next, the editorial unit 5400 of the receiver 5000 edits the variable-length addressable CM transmitted from the CM distribution server 4000 according to the time length of the CM frame included in the addressable CM frame information 91 (S4). Further, the editorial unit 5400 has the same time length of the CM frame registered in the addressable CM frame information 91 by combining one or a plurality of variable length addressable CMs or one or a plurality of fixed length addressable CMs. A combination 50 of addressable CMs having a long reproduction time is organized.

Further, the reproduction control unit 5500 stores the CM reproduction record information in the storage unit 5800.

Then, the transmission unit 5600 of the receiver 5000 transmits the CM reproduction record information stored in the storage unit 5800 to the management server 3000 in association with the receiver ID (S6). The receiver 3100 of the management server 3000 associates the receiver ID received from the receiver 5000 with the CM reproduction record information and stores it in the storage unit 3400. Further, the analysis unit 3200 of the management server 3000 analyzes the tastes and the like of the viewer based on the CM reproduction record information and the attribute information of the viewer. Then, the notification unit 3300 of the management server 3000 notifies the broadcasting station 1000 of the analysis result by the analysis unit 3200. Here, it is assumed that the processing of this sequence diagram is completed.

In the prior art, a broadcasting station system combines a plurality of pre-stored CMs so that the length of the CM frame and the total playback time of the plurality of CMs broadcast in the CM frame are the same. rice field. Since CMs of various time lengths are stored in the broadcasting station system, the broadcasting station system could easily adjust the total playback time by combining these. On the other hand, since the storage area of the receiving device such as a television device is smaller than the storage area of the system of the broadcasting station, the number of addressable CMs that can be stored in advance is limited. Therefore, there is a possibility that there is a difference between the time length of the CM frame in the broadcast program and the playback time of the addressable CM.

For example, if the reproduction time of the addressable CM is shorter than the time length of the CM frame, a part of the normal CM delivered by the broadcast wave will be broadcast after the reproduction of the addressable CM.

On the other hand, in the receiver 5000 of the present embodiment, the addressable CM frame information 91 in which the CM frame ID for specifying the CM frame in which the normal CM can be replaced with the addressable CM and the time length of the CM frame are associated with each other.

Further, the receiver 5000 of the present embodiment further receives a fixed-length addressable CM from the CM distribution server 4000, and receives one or a plurality of variable-length addressable CMs or one or a plurality of fixed-length addressable CMs. By combining them, a combination 50 of addressable CMs having a reproduction time having the same length as the length of the CM frame is formed. Therefore, according to the receiver 5000 of the present embodiment, the total playback time of a plurality of addressable CMs can be set to be the same as the time length of the CM frame, and one addressable CM fills the time. Even in a CM frame for a long time, which is difficult, the addressable CM can be reproduced.

Further, the receiver 5000 of the present embodiment adds a still image to the end of the addressable CM combination 50 when the reproduction time of the addressable CM combination 50 is shorter than the length of the CM frame. Therefore, according to the receiver 5000 of the present embodiment, the time length is adjusted by displaying a still image so that the CM frame in the broadcast program and the playback time of the addressable CM are made the same length more reliably. can do.

Further, the receiver 5000 of the present embodiment transmits CM reproduction record information indicating the reproduction record of one or a plurality of variable length addressable CMs or one or a plurality of fixed length addressable CMs to the management server 3000. Therefore, according to the receiver 5000 of the present embodiment, the reproduction result of the addressable CM in the receiver 5000 can be used for the analysis in the management server 3000.

Further, the CM distribution server 4000 of the present embodiment is a condition of the CM frame ID registered in the addressable CM frame information 91 from the receiver 5000 and the addressable CM that can be reproduced in the CM frame specified by the CM frame ID. Is received, and a variable-length addressable CM that can be reproduced in the CM frame is searched. The CM distribution server 4000 of the present embodiment transmits the searched variable-length addressable CM to the receiver 5000. Therefore, according to the CM distribution server 4000 of the present embodiment, it is possible to distribute an addressable CM that can be reproduced by the receiver 5000. Further, since the CM distribution server 4000 of the present embodiment distributes the variable length addressable CM, the time length of the addressable CM is changed on the receiver 5000 side, so that the time length of the CM frame in the broadcast program can be changed. , It is possible to reduce the occurrence of a difference in the length of the reproduction time of the addressable CM.

Further, the transmission / reception system S of the present embodiment includes a CM distribution server 4000 having the above-mentioned functions and a receiver 5000, whereby the time length of the CM frame in the broadcast program and the reproduction time of the addressable CM are provided. It is possible to reduce the occurrence of a difference in the length of the.

Further, in the present embodiment, the CM management server 6000, the CM distribution server 4000, and the management server 3000 have been described as separate devices, but some or all of these servers may be integrated. For example, the CM distribution server 4000 and the management server 3000 may be configured as one server, or the CM management server 6000 and the CM distribution server 4000 may be configured as one server.

Further, in the present embodiment, the transmission / reception system S includes a receiver 5000, a CM distribution server 4000, and a management server 3000, but is not limited to the configuration. For example, the transmission / reception system S may include only the receiver 5000 and the CM distribution server 4000, or may further include other devices. Further, the transmission / reception system S may include the system of the broadcasting station 1000.

Further, in the present embodiment, the receiver 5000 is supposed to reproduce the addressable CM in the CM frame in the broadcast program transmitted from the broadcast station 1000 by the broadcast wave or the like, but in the video-on-demand distribution data. You may play the addressable CM in the CM frame. Further, the receiver 5000 may reproduce the addressable CM in the CM frame in the moving image data recorded on the BD, DVD, built-in HDD or the like.

Further, in the present embodiment, the receiver 5000 acquires the addressable CM frame information 91 from the broadcast wave, but the acquisition source of the addressable CM frame information 91 is not limited to the broadcast wave.
