Also, the reproduction function reproduces the content recorded on the optical disk by the disk drive 5005 . The optical disk here may be one recorded by a recording function, or may be a ready-made product in which data such as movies and TV dramas are stored and sold.

(Replacement playback of addressable CM)
FIG. 7 is a timing chart during playback of addressable CMs in the system according to the first embodiment. In the example of FIG. 7, it is assumed that the receiver 5000 has already downloaded an addressable CM that matches the taste of the viewer to the recording medium 5001 . Alternatively, it may be downloaded to the recording medium 5001 by asynchronous communication or the like while the recorded content is being reproduced.

As shown in FIG. 7, in the system of Embodiment 1, when the main part of recorded content starts to be reproduced, the system waits for the next CM frame, and plays a little before the CM frame (for example, by a predetermined time such as 10 seconds). Then, the old CM included in the recorded content is replaced with the addressable CM, the addressable CM is reproduced at the timing of the start of the CM frame, and the continuation of the main part is reproduced at the end of the CM frame (or the reproduction of the addressable CM). back to

In the case of optical discs on the market, there may be a CM frame at the beginning, that is, before the main story.

Note that the distinction between the main part and the CM frame may be made, for example, at a point where the audio is switched between monaural and stereo, like an existing function for automatically setting chapters.

(Update processing and replacement processing)
FIG. 8 is a flowchart of an example of the procedure of addressable CM update processing according to the first embodiment.

As shown in FIG. 8, the integrated controller 5200 waits for a predetermined period of time (for example, one month or one week) from the acquisition of the previous addressable CM (No in step S01). Yes in step S01), update the storage area of the addressable CM (step S02). In step S<b>02 , the integrated controller 5200 receives delivery of an addressable commercial suitable for the viewing history of the receiver 5000 and user attribute information from the commercial delivery server 4000 and stores it in the recording medium 5001 .

FIG. 9 is a flowchart illustrating an example of the procedure of addressable CM replacement processing according to the first embodiment.

As shown in FIG. 9, the integrated controller 5200 waits for a predetermined period of time until the CM frame (No in step S12) after starting viewing of the recorded content (step S11), and when the timing is reached (step Yes in S12), the old CM included in the recorded content is replaced with an addressable CM (step S13). Also, after completing the reproduction of the addressable CM in step S13, the integrated controller 5200 returns the process to step S12 and waits for the next timing.

As described above, according to the present embodiment, prerecorded contents such as recorded broadcast programs, movies and TV dramas stored in advance on optical discs and the like and sold can be recorded at the time of recording or at the time of sales start. Even if advertisements are included, when playing back the recorded content, instead of advertisements that have lost the value of playback due to the passage of time, commercials that are new and that utilize analysis results such as viewer preferences and purchasing behavior are used. can be replaced. Therefore, according to the present embodiment, it is possible to distribute advertisements that match the user's tastes and attributes in a timely manner even during playback of recorded content.

[Modification]
Since this modification is a modification of Embodiment 1, the same reference numerals are used for the same parts, and detailed description thereof is omitted. In this modified example, the process of FIG. 10 is performed instead of the addressable CM update process (FIG. 8) and the addressable CM replacement process (FIG. 9) in the first embodiment. FIG. 10 is a flowchart of addressable CM update and replacement processing when recorded content is reproduced according to the present modification.

When starting to view the recorded content (step S21), the integrated controller 5200 determines whether a predetermined period of time (for example, one month or one week) has passed since the previous acquisition of the addressable CM (step S22). If the period has passed (Yes in step S22), the integrated controller 5200 updates the storage area of the addressable CM (step S23). In step S 23 , the integrated controller 5200 receives from the CM distribution server 4000 an addressable CM that is suitable for the viewing history of the receiver 5000 and the attribute information of the user, and stores it in the recording medium 5001 .

Further, in step S22, if the predetermined period has not elapsed since the acquisition of the previous addressable CM (No in step S22), the integrated controller 5200 skips step S23 and advances the process to step S24.

In step S24, the integrated controller 5200 waits until the CM frame reaches a predetermined time (No in step S24). Replace with CM (step S25). Also, after completing the reproduction of the addressable CM in step S25, the integrated controller 5200 returns the process to step S24 and waits for the next timing.

According to such a modified example, it is possible to update an outdated addressable CM each time some recorded content is viewed.

For example, if the recorded content is a TV drama that has been broadcast in the past and is recorded on an optical disk or the like and sold, the above-mentioned CM insertion point is the point where the CM was inserted at the time of broadcasting. Appropriate. In addition, in preparation for such operation, information (advertisement insertion point information) indicating the timing at which the CM can be inserted may be inserted in the optical disk or the like in advance.

Also, if the recorded content is a movie recorded on an optical disk or the like and sold, for example, it is appropriate that the above-mentioned CM insertion point be a place where it can be determined that there is a high possibility that it is a scene change. is. For example, a blackout (or whiteout) portion of the screen can be cited as a portion where it can be determined that there is a high possibility of a scene change. Whether the screen is blacked out (or whited out) can be determined, for example, by comparing the brightness of the entire screen with a predetermined threshold. In the case of such operation, the information of the portion where it is judged that there is a high possibility that the scene is changed is treated as the above-mentioned advertisement insertion point information.

FIG. 12 is a flow diagram illustrating an example of the procedure of addressable CM insertion processing according to the second embodiment.

As shown in FIG. 12, after starting viewing of recorded content (step S31), the integrated controller 5200 waits for a predetermined period of time until the commercial insertion point (No in step S32). If Yes in step S32), the reproduction of the recorded content is paused and the addressable CM is inserted and reproduced (step S33). Also, after completing the reproduction of the addressable CM in step S33, the integrated controller 5200 returns the process to step S32 and waits for the next timing.

In each of the above-described embodiments, a television broadcast program or the like is used as an example of recorded content. , the addressable CM may be replaced/inserted and reproduced.

In each of the above-described embodiments, the recording medium 5001 is shown as a magnetic disk. I don't mind.

Also, the addressable CM may be stored in a volatile memory or cache instead of the HDD or media. In such a case, the addressable CM uses a storage capacity unnoticed by the user, is downloaded from the CM distribution server 4000 unnoticed by the user, and is updated as necessary. With such a configuration, the HDD and media, which the user manages and cares about the remaining capacity, are not used for addressable CM. Therefore, in this case, it is possible to prevent the addressable CM from giving the user a negative impression that the memory capacity controlled by the user is being eroded.

Further, in each of the above-described embodiments, the addressable CM is acquired from the CM distribution server 4000, but the implementation is not limited to this. You may acquire CM as. In this case, as a CM to be an addressable CM, for example, recorded data of a television broadcast program in which the CM is inserted in the main content can be considered. CM metadata included in the recorded data can be obtained. Therefore, for example, the integrated controller 5200 acquires the CM metadata included in the recording data in the storage medium 5001 and stores it in a predetermined storage area, and when the content is reproduced, the CM metadata stored in the predetermined storage area is retrieved. By referring to the data, it is possible to select CMs that match the viewing history and attribute information and use them as addressable CMs.

Further, in each of the above-described embodiments, an example in which the means for providing content to the receiver 5000 is terrestrial waves or satellite waves has been described. , for example IP broadcasting. In this case, the receiver 5000 receives IP broadcast via, for example, the broadband content processing section 5100 (see FIG. 4).

In each of the above-described embodiments, the servers are divided into the broadcasting station server 1100 including the CM management server provided in the broadcasting station 1000, the management server 3000, and the CM distribution server 4000. The number of servers 1100, 3000, and 4000 does not need to be actually three. The server group of the configuration may be configured to realize the functions of the servers 1100, 3000, and 4000.
