ABSTRACT:
A filter limits the bandwidth of a caption video signal in a video disc player to minimize color beats when the caption signal is displayed along with a picture video signal on a television receiver. The filter delay, which would otherwise cause offset between the caption and an associated background signal used to enhance visibility of the caption, is compensated for by extending the time duration of each occurrence of the background signal by a multiple of the filter delay.
