ABSTRACT:
Digital video tape recorder which provides a smooth continuation in a video picture reproduced from a medium on which new digital video signals immediately follow previously recorded digital video signals. A signal processor processes a unit consisting of a field or frame interval of a video signal into a digital video signal. The digital video signal is recorded with identification data on a plurality of recording tracks on a magnetic tape. When a new digital video signal is recorded immediately following an existing digital video signal, the magnetic tape is rewound by a predetermined distance, then the digital video signal and identification data that had been recorded previously are reproduced until an end of a unit is reached, whereupon recording circuitry is activated to record the new digital video signal.
