Abstract
Sync positions are detected from a video signal. The detected sync positions are processed (e.g., averaged) to generate modified sync positions. The detected sync positions and the modified sync positions are selectively used to sample and synchronize a color signal derived from the video signal. For example, the detected sync positions and the modified sync positions may be selectively used to sample and synchronize the color signal responsive to differences between the modified sync positions. The invention may be embodied as apparatus and/or methods.
