<p>PURPOSE:To eliminate cases wherein a program different from a desired program is recorded and a magnetic tape is wasted by sending a broadcasting wave which is generated by modulating a carrier with a program code and a program start or end code from a television broadcasting station by broadcast programs right before the start of the broadcasting of each broadcast program or at the end of the broadcasting. CONSTITUTION:The broadcasting station sends a broadcast code including a specific program code corresponding to each broadcast program right before the actual start of the broadcast program or at the end of the broadcast program. A program code monitor part 9 compares the program code included in the broadcast code which is sent by broadcast programs from the broadcasting station and inputted through an antenna 8 with a specific program code which is reserved previously for automatic programmed video recording to detect the coincidence between both the codes. Consequently, even when the broadcasting time of a desired broadcast program to be programmed and recorded is changed, the desired broadcast program can securely be recorded and the magnetic tape can effectively be used without any waste.</p> |
