ABSTRACT:
An apparatus for use in conjunction with a processing system of the type which receives an input video signal comprising successive scanlines, each of which consists of a blanking portion that includes timing signals followed by an active portion representative of color picture information. The processing system is of a type that has an inherent delay whereby the output thereof is a television video signal delayed with respect to the input video signal. The invention is directed to an apparatus for generating a revised output video signal having timing signals in synchronism with the input video. In accordance with the invention there is provided a means for generating blanking portions in synchronism with the blanking portions of the input video signal. Means are further provided for selecting portions of the output of the processing system which occur between the generated blanking portions and for combining the generated blanking portions and the selected portions to produce the revised output video signal.
