Abstract

PURPOSE:To reject cross talk of audio signal and to reproduce the audio signal without interruption, by recording the information content of compressed audio signal every time of adjacent tracks through a part of overlapping. CONSTITUTION:The audio signal in time compression is made for frequency split multiplex processing, the track is formed for the same length as the video signal in frequency time sharing multiplex, both the signals of video signal and audio signal in time compression are recorded on one track, the said signals are recorded on each track before and after the track apart from the said track by (n), and the audio signal in time compression and the audio signal apart by (n) tracks and compressed similarly are recorded so that a part of the same information content can be overlapped. In this case, a trapezoid wave generating circuit 51 plays a role of advancing the phase of the switching signal to the input pulse to a sampling hold circuit 48 to avoid discontinuous point at overlap recording. Further, at reproduction, the audio signal in time compression and reproduced intermittently is in time expansion to restore it into the original audio pitch and to reproduce it as a continuous signal.
