Video signal recording and reproducing apparatus, including means for discriminating the mode of multiplexing of an audio signal

摘要

A video signal recording/reproducing apparatus includes a recording medium having a video track and an audio track separately formed, wherein a video signal is recorded in the video track and an audio signal to be multiplexed and a discrimination signal of a low frequency and a low level representing the kind of multiplexing thereof are recorded in the audio track. Decision is made of the kind of multiplexing of the audio signal, such as a bilingual mode, a stereo mode or a monaural mode, as recorded in the audio track, in response to the descrimination signal reproduced from the audio track and a multiplexed audio signal is produced in response to the decision signal representing the kind of the audio signal and the audio signal reproduced from the audio track.
