Abstract

PURPOSE: To synchronize recording and reproducing of video signal and PCM signal through a VTR by controlling VTRs and a PCM signal processing unit with the standard synchronizing signal as basic clock.
CONSTITUTION: A VTR 2 which records and reproduces the video signal and a PCM signal processing unit 6 which pulse-code-modulates the audio signal, etc. to the same style as that of the video signal, etc. are controlled by the clock in which the basic clock outputted by a standard synchronizing signal generator 1 is a reference. Hence, the video signal and PCM signal synchronize and this makes it possible to synchronize the video reproduction signal of the VTR 2 and the audio reproduction signal of the VTR 4 or dub the audio PCM signals synchronous to the video signal of the VTR 2 in the VTR 4 through pulse code modulation of the audio reproduction signal of the VTR 2.
