ABSTRACT:
An audio and video signal coding system in which the normal sync pulses in the horizontal and vertical blanking intervals are suppressed, and clock and control data as well as digital audio data is inserted therein. The data, both audio information and clock data in the horizontal blanking interval is further distorted by the application of a periodic waveform and/or voltage level enhancement of certain portions of the horizontal blanking interval.
