ABSTRACT:
A synchronization system for serial digital television signals compares successive sync signals to form an error signal and also delays the digital signals. The information signal delay is changed during loss of signal by an amount in accordance with the error signal to resync the signal. Thus valid information occuring before loss of synchronization is utilized. The delay means can comprise a pair of RAMs.
