ブレータ回路等が使用される。The demodulation unit 11 receives the video signal Vi on which the program replacement signal including the I, Q, and S signals is superimposed, and extracts only the S signal. Here, the S signal is a signal that is continuously transmitted only during the time when the advertisement program is being transmitted. Control signal generating section 12 and 13 detects a pulse rising and falling portions of the S signals, recording stop movement of VTR14
The control signals Sa and Sb are respectively sent to the VTR 14 with a delay of a preset time in accordance with the operation and the recording restart operation . This delay time is the time required for the VTR 14 to start operating, that is , when the VTR 14 stops recording.
Stop operation and recording restart operation are started, then operation is completed
For example, an unstable multivibrator circuit or the like is used to set the delay time according to the time required until the delay time can be continuously varied.
