Abstract

PURPOSE:To prevent discontinuity of audio signal, by taking an audio signal of a track before and after, in compulsively changing the track, as the same signal or a non-recording, at the reproduction of a disc recording information. CONSTITUTION:An audio signal from input terminals 1 and 2 is frequency- modulated 6,7 and inputted to a mixing circuit 8. A video signal from a terminal 3 is gated with a pules inputted from an input terminal 4 the same time as a kick control signal at a gate 9, and a signal after a color burst signal beta during one horizontal period is eliminated and mixed 10. The mixing circuit 10 mixes a kick signal alpha from a terminal 5 and inputs the result to mixing circuit 8. The kick signal is inputted at a vertical blanking period of a video signal and as to the audio signal, a track before and after to be kicked is taken as the same signal or non-recording. Thus, the video and audio can be reproduced without discontinuity. This system is suitable in recording questions, answeres and interpretation on a video disc for study.
