Abstract
A method and apparatus is disclosed for providing a unique digital synchronization word in a generally continually moving digital data stream wherein the data stream represents at least one digital component of a composite video signal having horizontal and vertical blanking intervals, with the horizontal synchronization pulse having been removed therefrom. The apparatus inserts the synchronization word in the horizontal blanking interval, preferably on alternate lines without interrupting the flow of the data stream and discards the information content thereof in the horizontal blanking interval as well as during a significant portion of each vertical blanking interval.
