Abstract
PURPOSE:To apply composite recording of a video and an audio signal by applying time axis compression respectively to a digitized video and audio signal, applying time division multiplex and DA conversion so as to convert the signal into an analog signal and record the result. CONSTITUTION:A video signal from a tuner circuit 14 is digitized by an AD converter 15 and subject to time axis compression by a time axis compression circuit 16a. On the other hand, the audio signal is given to a time axis compression circuit 16b via a PCM processor 17 and a time base collector circuit 18. The video signal and audio signal subject to time axis compression are multiplexed while the one horizontal scanning period is subject to time division by a changeover switch 19, and converted into an analog signal by a DA converter 20 and recorded on a video track of a magnetic tape 4 via a recording and reproducing circuit 3 and a rotary head 5. The video signal and audio signal reproduced by a rotary head 4 and the recording and reproduction circuit 3 are subject to time axis expansion by time axis expansion circuits 24a, 24b.
