For example, in the setting of a character who opposes the marriage of character A and character B, A's father, A's friend, A's company's boss, etc. may be set, B's mother, B's friend, B's All programs for the case where a teacher is set up are produced and kept at the time of production, and in setting up such characters, the story can be developed in a direction in which the opinions of the viewers are reflected by investigating and determining the opinions of the viewers.

3 is a flowchart for explaining a method of transmitting an interactive broadcast program according to the present invention.

When the automatic transmission list is input in the automatic transmission control program (APS) (200), the video tape of the VCR1 of the program file unit 40 is reproduced to start guiding the interactive broadcast program (202). In the playback apparatus of the main control room, the tapes of the broadcast program to be transmitted are prepared by the tapemen so that the VCR2 is the main program and the VCR3 and the VCR4 are prepared as subprograms (204). After the preparation is completed, when the broadcasting is started, the VCR2 is operated so that the sub-program of the first part is provided to the master control unit 80 (206), and the provided video and audio signals are modulated into satellite television signals and thus the satellite (100). Is sent out. Thus, satellite broadcasting is displayed on the satellite television receiver of each subscriber. At the end of this section, it is checked whether the polling start time is reached (208). When the polling start time is reached, the automatic sending control unit 70 generates an automatic sending control signal for operating the polling system (210).

In response to the automatic transmission control signal, the polling processing unit 50 inputs an APS signal (224) and checks whether or not to start the polling (226). If the poll is to be started, the survey information for the poll is provided to the additional information generator 60. The additional information generating unit 60 converts the provided questionnaire information into a format of the additional information and provides the converted information to the data encoder through the master control unit 80. The transmitter 20 multiplexes additional information with video and audio data and transmits the satellite to the satellite.

Thus, in the subscriber television, the poll questionnaire is displayed in subtitles. When the viewer selects the answer corresponding to the questionnaire on the subtitle with the remote controller, the viewer selection information is transmitted to the satellite through the indoor unit, the outdoor unit, and the antenna.

The broadcasting station receiver 30 receives the downlink signal provided from the satellite, amplifies the channel, decodes the channel, and decodes the data through a data decoder (228).

The decrypted data is provided to the poll processing unit 50. The poll processing unit 50 counts the viewer information provided. The counted polling progress is relayed to each subscriber in real time in the additional information through the above-described transmission and reception process (230). The polling processing unit 50 checks the polling end time (232), and if the polling ending time, the polling result is provided to the automatic transmission control unit 70 (234).

The automatic transmission control unit 70 closes the poll (212) and generates an automatic transmission control signal according to the survey result (214). According to the poll result (216), if the number of votes for question A is large, VCR3 is selected (218). If the number of votes for B is large, VCR4 is selected (220). By playing and transmitting the selected VCR, the program proceeds in the direction of play development in which the viewer opinion is reflected.

Preparing the next program. The same method as described above is repeated to broadcast the program (222).
