  The present invention relates to an interactive broadcasting system in which a viewer can create and send a program. More specifically, the program sender can easily change the program configuration, and the viewer can easily change the program being received. The present invention relates to an archiving method for an interactive program broadcasting system that enables participation in a TV program.

  Known TV programs include programs in which viewers participate, such as quiz programs and karaoke tournament programs. Viewers of these programs have a desire not only to watch but also to appear in the program as participants, and these programs are realized by responding to the request. Furthermore, there are many requests that viewers who have the same hobbies and interests create and broadcast their own programs and participate.

  However, in order for viewers to participate in these programs, it is necessary to go to broadcast stations and program relay venues, and there is a problem that viewers cannot easily participate in program viewing. In order to solve this problem, in Patent Document 1 described later, a camera and a microphone are placed on the receiver of the viewer, and the video / audio of the viewer is transmitted to the broadcasting station, and a viewer participation program is created using the audio / video. A system has been filed. In this system, it is possible to create a viewer-participation-type program without a sense of incongruity by appropriately changing the contents of the program progress according to the situation of the viewer participating in the moderator according to the progress of the program. .

  In addition, it is conceivable to record the program on a storage medium such as a video tape or DVD during the program broadcast in order to perform the re-broadcast after the broadcast of the viewer-participatory program after the broadcast. In many cases, the progress is not as scheduled, and when correction is required after recording, there is a problem that correction and editing cannot be easily performed. Furthermore, it has been difficult with the conventional program recording method to respond to a request from a viewer such as wanting to view a recorded program as a digest program.

As a means to solve this problem, for example,
JP 2002-369175, JP 2001-169268 A can be mentioned.

When the accumulation of the material is completed, the index information registered in the material index DB 207c is transmitted to the information management server 12.

  Next, in FIG. 10, the flow of materials for realizing program rebroadcast after the program ends will be described. The participation program communication device 14d used by the viewer who wants to rebroadcast the viewer participation program after the program ends obtains the program progress table 200 from which the program has ended from the information management server 12, and himself Is stored as the program progress table 200d. The program progress table analysis means 61 detects a material necessary for creating a program from the program progress table 200d, and requests the participating program communication device 14b that records the material to send the recorded material. .

  FIG. 9 shows a case where the participation type program communication device 14b cannot respond for some reason. In this case, the participation type program communication device 14d makes an inquiry to the information management server 12. The information management server 12 searches the material index list DB 203 by the material information management means 86 and answers the existence of the participation type program communication device 14c storing the same material. The participation type program communication device 14d receives an answer from the information management server 12, requests the participation type program communication device 14c to send the material, and reproduces the received material by the TV monitor 206 and the speaker 206. .

  With the above operation, broadcast of the viewer participation program by the participation program communication device and rebroadcast after the end of the broadcast are realized.

Next, the program composition function of the participation type program communication apparatus 14 will be described with reference to the functional block diagram of FIG.
The participation type program communication device 14 has a program progress table receiving means 57 and obtains the program progress table 200 from the information management server 12. The program progress table analysis means 61 analyzes the program progress table 200 and the material selection means 62 selects materials necessary for the progress of the program. For the necessary material, the material requesting means 58 is used to request the participation type program communication apparatus 14 or the material server 18 having the material to transmit the material. Further, it has the material request response means 59 for responding to the request from the material request means 58 of the other participatory program communication device 14.

  When the participation program communication device 14 that records the material does not respond, the inquiry means 55 makes an inquiry to the information management server 12 about the location of the alternative material, and as a result, the recognition information about the device that has been answered. Based on this, the material billing means 58 is used to bill the material. Examples of the participatory program communication device 14 not responding include cases where requests from a plurality of other participatory program communication devices 14 are concentrated or a state where the participatory program communication device 14 is not operating due to some trouble.

FIG. 11 is a flowchart showing details of the operation of the information management server 12 that receives an inquiry.
First, in step S01 (hereinafter, step is omitted), the presence or absence of an inquiry from the participation type program communication device 14 is confirmed. If there is no inquiry (determination of S01 is negative), the process is terminated. If there is an inquiry, the material index list DB 203 is searched using the material index information included in the inquiry information in S02, and the corresponding alternative material index information is extracted.

  In S03, the number of substitute material index information is determined, and if it does not exist (determination in S03 is negative), the participation type program communication apparatus 14 inquired in S08 is notified that there is no substitute material. . Receiving this information, the participation type program communication device 14 determines that the program cannot be reproduced because there is no information, and ends the program.

  In S03, if the number of substitute material indexes is not 0, it is determined in S04 whether the number of substitute material indexes is 1. If 1, the number corresponds to the participating program communication apparatus 14 that made the inquiry in S07. Notify index information of alternative materials. The participatory program communication apparatus that has received this information requests the material from the participatory program communication apparatus 14 that records the material based on the alternative material index information, and configures the program with the received material.

  If the number of alternative material indexes is 2 or more in S04, the participation inquired to each participating program communication device 14 that records those materials in S05 based on the index information of each alternative material extracted in S05 Each network distance to the type program communication device is calculated. In S06, an alternative material having the shortest network distance is determined.

  In S07, the participatory program communication device 14 that made the inquiry is notified of the index information of the alternative material determined in S06. The participatory program communication apparatus 14 that has received this information requests the participatory program communication apparatus 14 that records the material from the alternative material index information, and composes a program with the received material.

  FIG. 12 is a detailed flowchart for deleting a material registered by the participation type program communication apparatus 14. The participation program communication device 14 stores the used participant's video and audio as the original material in the material DB 206 when participating in the participation program. Also, the video / audio received in the reception of the program is stored in the material DB 206 as an alternative material (duplicate).

  By this storing operation, a large number of alternative materials are accumulated by many viewers participating in and viewing the program. Therefore, in the participating program communication apparatus 14 for newly viewing the program, it is the most network-oriented. Program composition is possible using nearby materials. However, on the other hand, due to the occurrence of a large amount of alternative materials, the material information stored in each participating program communication device 14 increases, and the capacity of the material DB 206 is compressed. A procedure for deleting a material once accumulated will be described with reference to the flowchart shown in FIG.

  First, in S21, the material index DB of the participation type program communication device 14 is searched, and in S22, it is determined whether there is an alternative material. If the determination in S22 is negative and there is no substitute material, this routine ends. If there is a substitute material, the transmission history of the substitute material is confirmed in S23.

  The transmission history of the substitute material indicates the latest date, time, and frequency at which the corresponding substitute material was used by the other participating program communication device or its own participating program communication device. It is determined whether or not the retention period is extended based on the date and frequency.

  If it is determined in S24 that it is within the storage period, this routine ends. However, if the storage period has elapsed, the corresponding alternative material is deleted from the material DB 206 in S25.

  Further, the index information of the corresponding material is deleted from the material index information DB 207. Subsequently, in S26, the information management server 12 is notified of deletion information indicating that the alternative material has been deleted. The information management server 12 that has received the deletion information deletes the corresponding material index information from the material index list DB 203.

  With the above operation, the substitute material recorded in the plurality of participation type program communication devices 14 connected to the communication network 10 is maintained at an appropriate value.

  The embodiment of the system capable of easily creating, broadcasting, and re-broadcasting the program by distributing and recording the program material including the viewer video using the viewer participation type program communication apparatus will be described in detail. did.
