Claim One:
1. An apparatus for synchronizing an analog video signal formed of a plurality of associated video frames to a digital image formed of a plurality of pixels displayed on a digital display unit, comprising: means for determining a synchronizing horizontal resolution (Htotal) that includes, means for finding a plurality of features for a selected one of a range of Htotal; means for tracking each of the plurality of features for each of the range of Htotal; means for measuring a transition zone for each of the plurality of found features for each of the range of Htotal; means for determining the narrowest transition zone of the plurality of transition zones, and means for associating a particular one of the range of Htotal corresponding to the narrowest transition zone to the synchronizing horizontal resolution; and means for determining a synchronizing phase coupled to the means for determining the synchronizing horizontal resolution that includes, means for selecting an estimated phase based upon the synchronizing horizontal resolution; means for determining a flat region of a video signal corresponding to a selected found feature, and means for selecting the synchronizing phase based upon the flat region.
