ABSTRACT:
An apparatus is described for recording and playing back video frames with associated audio signals for use with a conventional television display. A magnetic loop is employed to store video frames for display with associated audio information being placed as a separate frame on another magnetic medium. A full program of video and audio frames may be received and selected from a remote transmitter and appropriately located on a magnetic medium for sequential display on the television display. A first embodiment uses a cassette tape with a video loop for storage and playback of a program. A second embodiment uses a pair of multiple track belts for program storage and playback. Pilot signals are employed to precisely store the video frames on the video loop and to automatically sequence the display and sound projection of the multiple video and associated audio frames.
