• This paper reports on a signal processing system for video disc and home use VTR based on the time-division-multiplex technique. In this system, the chrominance signal is compressed along the time axis and put in the horizontal blanking period. Thus, it is time-division-multiplexed with the luminance signal. The time-compression is achieved by the time conversion operation of specially developed analog memory. This memory transfers majority carriers in bulk silicon and is provided with sufficient frequency range for the time compression and expansion. In order to eliminate the influence of time base error which is generally introduced during recording and playback processes, a burst sinusoidal signal is added in the horizontal synchronizing pulse and a playback time reference is derived from it.
