<p>PURPOSE:To record a desired program without fail by sending a program code, which is uniquely attached to a program, from a television broadcasting station during a vertical flyback erasing period, extracting the code on the reception side, selecting it and activating/stopping a VTR. CONSTITUTION:The signal of a vertical flyback erasing period (VBL) is inputted from a conventional VTR circuit constitution part 105 through a video signal 106 to a VBL signal extraction circuit 101 together with normal picture information, and only the signal of the VBL is extracted. The program codes attached from the broadcasting station are registered by a program reservation registration part 102, and compared by a reservation selection part 103 according to signals from the VBL signal extraction circuit 101 and the reservation registration part 102. When the codes are matched to each other, the information of the channel and activation information is outputted to a VTR recording start/ stop circuit 104. The VTR recording start/stop circuit 104 starts recording by outputting a VTR recording start signal 107 to the VTR circuit constitution part 105 corresponding to the conventional VTR circuit constitution part.</p> |
