Abstract

PURPOSE:To achieve video reproduction during the audio information detecting period, by independently processing audio or video information from each pickup, through the independent performance of the detection of audio and video information by pickups in two systems. CONSTITUTION:Video information from a video disc 1 is alone detected at a pickup 2a and audio information is alone detected at a pickup 2b, and the result is demodulated into a video format signal respectively at demodulators 3a and 3b. The demodulated signal at the demodulator 3a is processed at a video signal processing circuit 4 and displayed on a display 7. The demodulated audio signal at the demodulator 3b is processed at an audio signal processing circuit 5 and temporarily stored in a buffer memory 8, a memory control section 10 is controlled at a time axis stretcher 9 to output an audio signal from a speaker 12. The frame number and/or identification signal from the demodulators 3a, 3b is read in at frame number detection circuits 13a, 13b to control a servo mechanism 15 and video and audio information are separately read in at the pickups 2a, 2b respectively.
