<p>PURPOSE:To remove the initial interruption of a succeeding program practically by forcing not to actuate a succeeding instrument until the program of a preceding instrument practically ends. CONSTITUTION:A video signal is inputted to a video signal detecting circuit 13 and an end signal detecting circuit 14 and a video signal switching circuit 15 and an audio signal switching circuit 16 are switched by a signal from the circuit 13. A start/stop control circuit 17 is actuated by an AND signal between the output of the circuit 14 and the output of the circuit 13 and a start signal is outputted. Therefore, the video signal and the audio signals 1, 2 stop at the output of the end signal from the 1st laser disc player LDP10 and only the signals expressed as SEDEL and END on the disc player are outputted to the video signal. The 2nd LDP11 is started by the end signal and a video signal is outputted to switch the circuits 15, 16. Consequently, the initial interruption of a trailing program is not porformed.</p> |
