Abstract

PURPOSE:To make smooth the selection of operation between the reproduction of audio and video, by providing the audio end detection circuit with the audio signal processing section for cooperation with audio reproduction muting circuit. CONSTITUTION:The signal obtained by scanning the track recorded on the recording media 9 is detected with the detection means 10 and fed to the demodulation circuit 11 after being converted into electric signal, the video format including the identifying signal is fed to the identifying signal separation circuit 12 and fed to the discrimination circuit 13 after separating the identification signal. This circuit 13 discriminates the identification signal and outputs the video information discrimination signal v or audio information discrimination signal A on the content, the signal V or A is fed to the selection circuit 14 and the output of the circuit 11 is fed to the video signal processing section 15 and the audio signal processing section 17 with selection. Further, the audio end signal of the audio end detection circuit 25 provided at the processor 17 is fed to the servo control circuit 26 taking the signals V and A as inputs, and sequential scanning is made while the signal A is received and the means 10 is controlled so that the scanning for one frame's share is repeated while the signal V is received.
