Video sequencer-processor
First Claim
1. A system for commutating and decommutating a frame by frame sequence of a plurality of surveillance television cameras, comprising:
- sequencing means connected to said television cameras for sequentially selecting ones thereof for recording;
coding means connected to said sequencing means for developing serial code groups in corresponding relationship with the selection of said cameras, said serial code groups each having an individual code combination for each said camera;
superimposition means connected to said sequencing and coding means for interposing the individual code combination for each camera within the vertical interval of each field received from said cameras;
recording means connected to said superimposition means to serially record the signals in said fields from said cameras with said combinations interposed therein in a single recording channel, said recording means including a recorder that controls the rate of recording said signals and also is connected to said sequencing means to advance sequential selection of said cameras at the same rate, thereby achieving recordation of said signals for time lapse video signal storage;
playback means selectively connected to said recording means for selecting individual ones of said camera output signals according to a predetermined one of said individual code combinations that are interposed in the vertical intervals of fields stored in said recording means;
video display means connected to said playback means for producing a visual image corresponding to said selected camera signals; and
storage means connected to said playback and display means for storing said selected camera signal and cyclically repeating said signal to said display means.

Abstract
Apparatus for selecting a particular signal group from a signal group sequence including a video recorder for sequentially recording the video signals from a plurality of surveillance television cameras, the signal group sequence comprising a sequential record of video fields interspaced in a predetermined order, together with a sequence code. During playback, a particular frame or field in the sequence is picked out according to the code associated therewith and is fed in parallel both to a video display and a disc storage device. At the completion of the selected frame the disc is unloaded into the display at its cycling rate to fill in the gap left by the discarded frames until the next frame sequence is initiated.
