Abstract

PURPOSE: To enable excellent dubbing with a simple constitution, by performing dubbing, by feeding the PCM signal restored into analog signal after reproduction to the PCM processing circuit controlled synchronizingly via the crystal oscillator with level adjustment.
CONSTITUTION: Analog signal is in PCM conversion with the PCM processing circuit 7 in synchronizing control with the clock based on the oscillated output of the crystal oscillator 12, redundant signal and additional error correction and compensation circuit 9, and transmission modulation circuit 10 and recorded on VTR2. Further, it is restored into analog signal at the circuit controlled with the reproducing sampling synchronizing clock stabilized at PLL 24. This signal is fed to the circuit 7 at almost full scale with the variable resistance 25 via the switch 8c having the contact DUB to become the PCM signal in synchronizing with the oscillated output of the oscillator 12 without being affected with temperature, etc. and at dubbing very little in period lag with a simple constitution, and at reproduction after dubbing, excellent dubbing removing the defect without servo operation can be made.
