Abstract

PURPOSE: To omit the individual transmission of the clock and to realize the economical facilities by using the synchronous signal of the video channel as the data clock of the aural channel.
CONSTITUTION: The synchronous signal is extracted via extractor 10 from the video signal given from video signal source 7 and then supplied to data signal source 1 to obtain the synchronization between the data signal and the video signal. The video signal transmitted through video channel 8 is supplied to receiver 9, and the synchronous signal is drawn out (11) from the reception video signal to be applied to data receiver 2. Thus, the data process is carried out.
