ABSTRACT:
An apparatus for a digital video tape recorder for detecting a sync signal in digital data includes: a data restoring device for producing serial data and a serial clock signal received from a reproducing head of the digital video tape device; a servo device for producing a head switching pulse and a super-video home system (S-VHS)/video home system (VHS) discriminating signal; an identification detecting device for producing a signal indicative of an end of reading one segment of tracks; and a sync signal detecting device, responsive to each signal produced by the aforementioned devices, for determining correspondence in sync patterns even in a case where not all corresponding bits coincide with one another, for removing erroneously detected sync patterns using a window situated around a position at which a sync signal is produced, and for detecting a sync signal.
