８ＴＯＰ）を出力する。This scheduled recording device includes a TV receiving circuit 1, a program code importing circuit 2, and a program code recognition circuit 3. The TV receiving circuit 1 converts the video signal selected by the tuner 4 into VIF.
5 (intermediate frequency amplifier), the video signal detected by the video detector 6 is outputted to the program code acquisition circuit 2, and the video signal for recording and the VI are sent through the video signal processing 7.
An audio signal for recording is obtained from F5 through audio detection 8. The program code import circuit 2 writes the video detection output obtained by the TV receiving circuit 1 into the memory 12 as program code data through waveform equalization 9, code identification 10, and data processing 11. In the program code recognition circuit 3, the CPU 13 compares the contents of the program memory 14 storing the program code to be reserved for recording with the contents of the memory 12, and if there is a match, sets the tuner 4 to that channel. ,
The recording start/end interface 15 receives the recording start signal (R
EC5TART) is output. Incidentally, when the tuner 4 enters the reserved recording standby state, it sequentially selects all channels set in the VTR until the program code is captured. In addition, after entering the recording state, if the program code currently being recorded is not captured, the recording start/end interface 15 sends a recording end signal (REC).
8TOP) is output.
