Abstract
A recording/reproducing method and its apparatus for recording and reproducing a plurality of different television signals, each consisting of a video component and an audio component. The recording/reproducing method includes selecting and delivering the video components of input television signals and extracting a control signal from each of the selected video component signals. From the control signal it is determined whether the selected video signal is to be recorded or played back. If the selected video signal is to be recorded, it will be recorded onto a specific pattern of recording tracks of a recording medium defined by the control signal. If the signal is to be played back, the control signal is extracted from the selected video signal to be reproduced and then, the video signal is reproduced according to the control signal. The stereo audio components of the television signals prior to recording are data compressed and multiplexed. Then the stereo components are recorded in two, left and right, channels. In playback, the audio signals are retrieved by the control signal from audio sound tracks of the recording medium.
