Abstract
Main panel and side panel components of a widescreen television signal are intraframe processed over different frequency ranges, resulting in a noticeable difference between 'judder' motion artifacts of main and side panel images displayed by a receiver. A side panel field difference signal encoded in a transmitted widescreen signal is used by a receiver to eliminate the differential judder effect of displayed main and center panel information. The field difference signal contains field difference information over a range of frequencies between a first frequency above which the main panel component is intraframe processed, and a different second frequency above which the side panel component is intraframe processed.
