Video replay automation with manual control track editing
First Claim
1. A video recording and playback apparatus, comprising:
- a video recorder including a drive and first transducer for recording and reproducing a video program recorded in at least one helically scanned track on a storage medium;
a control track signal recorder and second transducer for recording a control track signal in a longitudinal track on the storage medium separate from said helically scanned track, said control track signal including control codes for said apparatus;
a decoder responsive to the control track signal during playback of the video program, the decoder being coupled to the drive for switching the apparatus between a forward play mode and a forward skip mode, as a function of respective skip and play control codes in the control track signal, for selectively skipping sections of the video program preceded by a skip code and followed by a play code;
editing means operable upon playback of the video program having a reviewing mode for reviewing the video program either with or without control by said control codes and an editing mode for said control codes; and
, an on-screen slay menu generator coupled to the editing means for generating an on-screen display for user control of said program reviewing and said control code editing modes.

Abstract
A video recording and playback device has a control track recorder for recording a control track signal including timing edges recorded on a tape or other storage medium together with the video program. A decoder is coupled to the control track signal and to the tape drive for switching among a forward play mode, a forward skip mode and a rewind mode, as a function of play, skip and rewind codes inserted into the control track as phase variations of edges other than those used for timing, or preferably as pulses with sloping edges distinct from the timing edges. In addition to selectively skipping sections of the video program preceded by a skip code and followed by a play code, such as commercial breaks, the device permits user editing of play and skip codes and selective multiple replays of sections of the video program preceded by a play code and followed by a rewind code. Replay can be continuous or for a predetermined number of replays, encoded in the control track signal with the play, skip or rewind codes. The play, skip and rewind codes and/or the number of play repetitions are user editable from an on screen menu for changing the content to be presented during a later playback.
