ABSTRACT:
A color video signal transmission system comprises an analog-to-digital converter for sampling an input composite color video signal at a sampling frequency nf.sub.sc and for producing first data, where n is a natural number and f.sub.sc denotes a chrominance subcarrier frequency of the input composite color video signal, a data converter for converting the first data into n data groups each comprising sampled data in the first data obtained for every sampling period 1/f.sub.sc and having the same phase with respect to the chrominance subcarrier of the input composite color video signal within one horizontal scanning period and for producing second data in which all of the n data groups are arranged in series for each horizontal scanning period, and a digital-to-analog converter for converting the second data into an analog video signal and for supplying the analog video signal to a transmission medium.
