<p>PURPOSE:To automatically change recording reservation time following the schedule change of broadcast time by transmitting the change information of the broadcast time of a broadcast program superimposing on the TV wave. CONSTITUTION:When a television wave 4a on which broadcast time change information is superimposed is received at a receiving circuit 5, a received signal is inputted to a broadcast time change information demodulation circuit 6a and a video signal demodulation circuit 6b, and broadcast time change information is demodulated by the broadcast time change information demodulation circuit 6a, and inputted to a microcomputer 1a in an automatic recording reservation time control circuit 1. The microcomputer 1a changes and stores the time and date, the channel, and the recording time of television broadcast with respect to automatic recording in the storage content of a RAM(memory) 1c based on inputted broadcast time change information. And a mechanical control circuit 3, etc., is operated under the control of the microcomputer 1a based on the storage content in the RAM(memory) 1c, then, the automatic recording is performed. In such a manner, the automatic recording of a program desired to be record can be performed correctly even when the broadcast time of the broadcast program is changed.</p> |
