Abstract

PURPOSE:To simplify the circuit constitution, by making two types of chromatic signals into multiplex chromatic signal through time division multiplex and transmitting two signals of luminance and multiplex chromatic signals in parallel. CONSTITUTION:A color video signal is constituted with a luminance signal component Y and two types of color different component signals I and Q, in total 3 types of components signals, and after they are sampled with integer times of subcarrier frequencies, a PCM multiplex chromatic signal Cq is obtained through time division multiplex only for the color difference component signal with a multiplexer 5, and the signal Cq and PCM luminance signals are coupled with a transmission line group transmitted in parallel with line drivers 15 and 16 for the transmission of the PCM color video signal.
