Abstract

A system for recording segmented video fields with segment identification codes includes circuitry to encode each segment of a given odd or even field with a different identification code. Further, each corresponding segment of all the other odd or even fields is likewise encoded with the same identification code. Thus, the first segment of any odd or even field has the same identification code which is different from any other identification code appearing for any other segment in any other odd or even field. The same applies to the second and all other segments.

Claims

1. Apparatus for use with a recorder of the type adapted to record segmented video field information on a recording medium, comprising

(a) means for producing discrete signals corresponding to the segments of a plurality of video fields each of which fields is comprised of the same number of segments;

(b) means for producing code signals corresponding to and identifying each segment of each field, said code signals

1. for any given field being all different, and

2.

3. recording medium. 2. The apparatus of claim 1 wherein said code signal producing means are means for producing respective discrete tone signals which are outside the video signal bandwidth.

2. for all fields being such that corresponding segments of all such fields have the same identifying code, and

(c) means for combining said code signals with their respective segment signals, thereby to form a composite signal for recording on said
