There is digital broadcasting that compresses audio signals and broadcasts a stream (transport stream) obtained by time-division multiplexing of video and audio digital signals of a plurality of programs via a transponder (satellite repeater). Since there are a plurality of transponders and a plurality of channels are multiplexed on each transponder, the number of channels is as large as several hundreds. Each broadcast includes service information (program name, program content, program start time,
Program end time, program genre code, program viewing appropriate information, etc.) are incorporated, so that a program desired by a viewer can be efficiently selected from multi-channel broadcasting.

On the other hand, a broadcast receiving apparatus for receiving such a digital multi-channel broadcast selects one of a plurality of transponders of digital broadcast received through a dedicated antenna by a tuner, and is included in the one transponder. One of a plurality of channels is selected by demultiplex processing, and a video / audio signal is output by decoding a digital signal of the selected channel. further,

However, as described above, the number of programs broadcast by digital broadcasting is enormous, and it is thought that the number of opportunities for program reservation and recording will increase. According to the technology described above, it is expected that a user's labor will increase due to an increase in recording opportunities. For example, when a recording reservation is made for a plurality of programs, if the total broadcast time exceeds the recordable time of the video cassette recorder, it is necessary for the user to exchange the cassette tape. Further, for example, in a case where three programs are reserved for recording, when two programs are in a common genre and one is in another genre, and when a program of a common jackle is to be recorded on a specific cassette tape, the user must use a cassette tape. You will need to replace them.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a broadcast receiving apparatus with a recording device control function which can reduce the user's labor as much as possible even if the opportunity to reserve a program and record is increased.
