A signal processing system for a high resolution digital video tape recorder (VTR) includes circuitry which processes the high resolution video signal to produce a relatively low resolution video signal which may be recorded on the tape with the high resolution video signal. The low resolution video signal is encoded using intra-frame techniques and recorded in fixed-length segments which appear at predetermined locations in the tape tracks. Low resolution segments representing images in different frames may be recovered and combined to produce an image which is suitable for display in trick-play modes. During normal play modes, the data stream representing the high resolution image is recovered in sequence. Accordingly, this high resolution image may be encoded using predictive coding techniques as well as intra-frame techniques.
