ABSTRACT:
A system for including audio data within a video signal. The number of frames of video data transmitted is reduced, thereby allowing greater time for each individual frame, thereby allowing the breezeway of each line of each frame to be lengthened. The breezeway resides between the horizontal synch pulse for the line, and the color burst signal. Samples of digitized audio are placed into the breezeways.
