ABSTRACT:
The apparatus and method is shown for transmitting one or more audio frequency signals on a television video signal including an encoder comprised of a pulse modulator responsive to the audio frequency signals and a combiner to combine modulated pulses from the modulator with the video signal. Also shown is a decoder for use with video signals output from above encoding apparatus and method for decoding the modulated pulses to recover the audio frequency signals.
