Abstract

PURPOSE: To put accurate dubbing into effect with constitution simplified by recomposing a video signal of a synchronizing signal and PCM data signal separated from a video signal reproduced from VTR by sharing a memory for storage.
CONSTITUTION: With multiplexer 21 switched, memory 20 used in recording is shared to demodulate a PCM video signal, reproduced by D/A converter 11, sample holding circuit 12, etc., via demodulating synchronizing signal generator 16, etc., thereby obtaining an analog video signal. In this case, a synchronizing signal and PCM data signal separated by signal separating circuit 9 are processed by generator 16, a video amplifier, etc., to obtain a waveform-shaped synchronizing signal, PCM data signal, synchronizing clock, etc., and then a reproduced PCM signal of deformed waveform in comparison with the original PCM signal is waveform-shaped by recomposing, so that it will be dubbed in another VTR by simple constitution with accuracy.
