ABSTRACT:
A system and method for compensating for drop outs present at the tape output of a video tape recorder. Compensation is effected by storing video information for at least one field in a field or frame store and detecting the presence of drop outs. When a drop out is detected the writing in of information to the store is inhibited so that the previously stored data is retained. The compensator may include additional storage for storing data indicative of drop out and frame identification so as to control processing at the store output to maintain correct color sub-carrier phase.
