ABSTRACT:
Moviola color picture quality is improved for a record and replay system wherein video sampled at a predetermined multiple of the color subcarrier frequency is recorded with each frame or field being disposed on a set of multiple tracks and with only a portion of the recorded information being intended for replay to reconstruct the color Moviola signal. Only pixel groups relating to entire color subcarrier cycles are recorded on the tracks so that a video signal having proper color information can be readily reconstructed therefrom during the Moviola mode. In one preferred embodiment, sequential color subcarrier cycle pixel groups are recorded on separate tracks with those to be replayed during the Moviola mode on a single track so that Moviola pixel groups on the single track can be repeated in sequence when reconstructing the Moviola picture and thereby supply instantaneously coherent information.
