Abstract
A processing system and a recording/reproducing system for a digital signal including a digital video signal and a digital audio signal. Upon transmission, the digital signal is transmitted after time-base compression and modulation. The transmitted signal is received and demodulated. In the case where the signal is to be transmitted to a plurality of recording/reproducing systems, address signals designating ones of the plural recording/reproducing systems and a control signal for controlling the start/stop of recording are transmitted. The recording by the recording/reproducing system is controlled so that it is made with the same format in either normal-speed or high-speed mode or in either normal or multiple recording mode.
