Abstract

The invention relates to a transmission-reception system for the transmission of animated color images or pictures and sound from two independent channels. The image signal is distributed over two independent channels, the luminance signal occupying one channel, while the chrominance signal, which is multiplexed with the sound, occupies with the sound the other channel. Separate luminance and chrominance signal processors are provided.
