ABSTRACT:
The invention relates to the multiplexed transmission of television audio-visual signals which comprise, for example, a luminance signal successive chrominance signals and at least one audio signal. The method in accordance with the invention utilises a subcarrier wave f, frequency modulated, on the one hand, by the chrominance signals, and on the other, by a train of isochronous pulses emitted during the line blanking intervals of the luminance signal and amplitude modulated by the audio-frequency signal. The multiplex signal which will subsequently be decoded, is obtained by frequency modulating a carrier wave by a signal which is the sum of the luminance signal Y and the above mentioned frequency modulated subcarrier.
