Abstract
A method, and apparatus, and logic encoded in one or more computer-readable media to carry out a method. The method is to sample analog video at a sample clock rate and at a phase selected from a set of phases based on a quality measure determined from the sampled video. The quality measure is based on statistics of pixel to pixel differences in a coordinate of the generated digital video that have a magnitude exceeding a pre-determined threshold.
