Recording technique for an audio/video program wherein the audio incorporates video change signals

Image Number 3 for United States Patent #4065795.

In the recording of audio-video programs in which the audio is time-compressed and converted into television format, the video frames associated with a given audio frame are recorded in a group immediately following the audio frame, and picture-change cue signals are recorded at selected lines within the audio frame so that on playback, displayed video can be changed at preselected points in the audio frame playback. A number of video frames can be recorded between successive audio frames wihtout introducing any discontinuity in audio playback.
