Abstract
An improved phase locking system in which an independently reproduced video signal is coded into a digitized video signal in response to a first clock pulse train, the first clock pulse train being produced from a synchronizing signal and/or a color burst signal contained in the video signal. The digitized video signal is stored and storage location as well as delay prior to storage is controlled in response to the phase difference between the synchronizing signal and a reference signal. The improved phase locking system reduces the frequency of occurence of visual shifts on the reproduced television picture.
