Abstract

A digital video signal processing system is described wherein analog video signal is sampled by a sampling clock phase locked to burst and the digital video samples are processed with a clock phase locked to horizontal sync. The respective sampling phases of the sampling clock are encoded and concatenated with the digital video samples for purposes of synchronously demodulating the color difference signals of composite video. Burst clock to line locked clock sample conversion is accomplished in a FIFO memory.
