System for recording and playing back individual frames of video and related audio signals

A method for displaying on a television display a television program formed of still video frames with accompanying explanatory audio formed into frames associated with the video frames comprising the steps of

• recording the audio frames on an audio magnetic medium,
• recording a video frame on at least one track on a video recording medium for repetetive playback and display on a television display,
• playing back the video frame recording on said track,
• moving the audio magnetic medium for the normal audio playback and projection on the television display of an audio frame associated with the video frame on said track,
• sensing an audio end signal at the end of the audio frame being played back to replace the video frame on said track with a successive video frame,
• playing back another audio frame associated with the successive video frame and
• continuing the video frame replacing and audio frame playing back steps until the entire television program has been displayed on the television display.

A method for displaying on a television display a television program formed of still video frames with accompanying explanatory audio formed into frames associated with the video frames comprising the steps of

• forming a composite signal wherein a plurality of individual still video frames are time separated by associated audio frame signals which are compressed in time at an elevated carrier frequency,
• moving an audio magnetic medium at an elevated speed to record the frames of audio at the elevated carrier frequency,
• recording a video frame from the composite signal on at least one track on a recording medium for repetetive playback and display on a television display.
• playing back the video frame recorded on said track,
• moving the audio magnetic medium at a reduced speed for the normal audio playback and projection on the television display of an audio frame associated with the video frame on said track,
• sensing an audio end signal at the end of the audio frame being played back to replace the video frame on said track with a successive video frame,
• playing back another audio frame associated with the successive video frame and
• continuing the video frame replacing and audio frame playing back steps until the entire composite signal representative of the television program has been displayed on the television display.
