Abstract
PURPOSE: To facilitate an easy reproduction of the audio PCM signal, by recording both the video signal modulation signal forming the multiplex signal and the audio PCM signal in synchronization and producing the clock signal based on the video signal during the reproduction.
CONSTITUTION: A reproduction/detection is given to the multiplex signal of the video FM signal and the audio PCM signal which are recorded in synchronization through a disk or the like via the detector 140. Then the video FM signal is isolated through the HPF150 and then demodulated by the FM demodulator 160 to be supplied to the isolating circuit 220. The horizontal synchronous signal delivered from the circuit 220 is applied to the clock generating circuit 230 consisting of the PLL, delay circuit, divider and others, and thus the circuit 230 produces the clock in synchronization with the audio PCM signal and also in correspondence to the bit synchronization. Accordingly, the audio PCM reproduced signal which is isolated through the LPF180 and received a waveform shaping is sampled accurately through the sampling circuit 200. Thus the reproduction can be failitated with a high assuredness for the PCM signal.
