Reproducing device of information signal recording disc

Abstract

Abstract PURPOSE:To reproduce various information in real time without using a buffer memory by reproducing still picture information, sound information and signal information practically recorded in real time with multi-channels through the 1st demodulator, a still picture decoder and the 2nd demodulator respectively. CONSTITUTION:The reproduced signals of various information practically recorded in real time on the basis of multi-channel recording by a player 20 are converted into low frequency signals consisting of a demodulated signal, a sound signal and a reproduced signal related to a still picture by a digital signal demodulator 22. These respective signals are demodulated into a signal processed by a still picture decoder 24 and a data/compressed sound demodulater 23 which is the 2nd demodulator, a still picture video signal, the sound signal, and a control signal. Thus, various information can be reproduced in real time without using a buffer memory for the sound signal and the control signal.
