Estimating the term…
A coder designed to receive color television audio video signals where a carrier wave is frequency modulated by the luminance signal and a sub-carrier wave is modulated by time multiplexed chrominance signal and audio signal; the carrier and the sub-carrier waves are linearly mixed and the resultant signal is converted into a multiplex wave formed by a train of length modulated pulses; the sub-carrier frequency is higher than the highest frequency of the luminance signal and the lowest instantaneous frequency of the carrier minus the highest frequency of the luminance signal is at least equal to the sub-carrier frequency; the multiplex signal may be transmitted and registered on a data carrier; and a decoder adapted for cooperating with the coder, for decoding the multiplex signal coming from the transmission channel or the read out data carrier and delivering the audio video signals.
A Coder having a multiple input provided for receiving colour television audio-video signals formed by a luminance video signal, a chrominance video signal of the sequential kind comprising horizontal blanking intervals and an audio signal accompanying said video signals, said coder comprising:
