Abstract
This invention is a method and apparatus for synchronization of high quality video like signals. Full sync tip to peak white video is digitized in the preferred embodiment along with oversampling and interpolation so that errors are kept to unexpected low levels. The preferred embodiment is described to pass one or more secondary signal with the video signal in a separate parallel but time related path. The use of the input signal for a reference to allow a fixed delay is also shown.
