Claim 7

An apparatus for playing back video and associated audio signals for display and sound projection on a conventional television receiver comprising a cassette of magnetic tape carrying video frame signals and audio frame signals in preselected order to associate each audio frame with a video frame, said video frame signals being flanked by video pilot signals and the audio frame signals being each terminated with an audio pilot signal; means for playing back signals from the cassette of magnetic tape; means for detecting the video pilot signals and producing a video start signal and a video end signal respectively representative of the beginning and end of a video frame; means for detecting the audio pilot signal to produce an audio end signal indicative of the end of an audio frame; means including a magnetic video frame storing loop for recording and playing back on said video loop; means initiated by the audio end signal and controlled by the video start and end signals for transferring video frames from the cassette of magnetic tape to the video loop; and means for driving said cassette and video loop at respective audio producing and video display speeds for audio projection and visual frame display on the conventional television receiver.

Claim 8

An apparatus for playing back video and associated audio signals for display and sound projection on a conventional television receiver comprising a cassette of magnetic tape carrying video frame signals and audio frame signals in preselected order to associate each audio frame with a video frame, said video frame signals being flanked by video pilot signals and the audio frame signals being each terminated with an audio pilot signal; means for playing back signals from the cassette of magnetic tape; means for detecting the video pilot signals and producing a video start signal and a video end signal respectively representative of the beginning and end of a video frame; means for detecting the audio pilot signal to produce an audio end signal indicative of the end of an audio frame; means including a magnetic video frame storing loop for recording and playing back on said video loop; means initiated by the audio end signal and controlled by the video start and end signals for transferring video frames from the cassette of magnetic tape to the video loop; and means for driving said cassette and video loop at respective audio producing and video display speeds for audio projection and visual frame display on the conventional television receiver.

Claim 13

An apparatus for recording and playing back video and associated audio signals for display and sound projection on a television display comprising means for receiving an input signal carrying a program formed of a plurality of video frames and associated audio frames and a program identifying code; means responsive to the input signal for identifying a desired program code and producing a gate signal indicative thereof; means actuated by the gate signal for passing the desired program of video and audio frames for playback; means including a magnetic storage medium for recording and playing back video and audio frames therewith, with the video frames being recorded on the magnetic medium with a predetermined time relationship with respect to associated audio frames; means for moving the magnetic storage medium at a first high operating speed to record audio frames and at a second low operating speed for playback of the audio frames; a magnetic video frame storage loop having a length selected to produce video frame signals for frame display on a conventional television receiver upon continuous rotation of the loop; means for producing video start and video end signals respectively indicative of the beginning and end of a video frame; means for sensing audio pilot signals recorded on the magnetic medium along with the audio frames to identify an audio frame and producing an audio end signal indicative of the end of the audio frame; means actuated by said audio end signal for storing a video frame on said loop in synchronism with the video start and video end signals; and means responsive to the audio end signal for initiating the playback of an audio frame associated with said stored video frame.

Claim 14

An apparatus for recording and playing back video and associated audio signals for display and sound projection on a television display comprising means for receiving an input signal carrying a program formed of a plurality of video frames and associated audio frames and a program identifying code; means responsive to the input signal for identifying a desired program code and producing a gate signal indicative thereof; means actuated by the gate signal for passing the desired program of video and audio frames for playback; means including a magnetic storage medium for recording and playing back video and audio frames therewith, with the video frames being recorded on the magnetic medium with a predetermined time relationship with respect to associated audio frames; means for moving the magnetic storage medium at a first high operating speed to record audio frames and at a second low operating speed for playback of the audio frames; a magnetic video frame storage loop having a length selected to produce video frame signals for frame display on a conventional television receiver upon continuous rotation of the loop; means for producing video start and video end signals respectively indicative of the beginning and end of a video frame; means for sensing audio pilot signals recorded on the magnetic medium along with the audio frames to identify an audio frame and producing an audio end signal indicative of the end of the audio frame; means actuated by said audio end signal for storing a video frame on said loop in synchronism with the video start and video end signals; and means responsive to the audio end signal for initiating the playback of an audio frame associated with said stored video frame.
