Abstract
A method and system for suppressing color-crossing error in decoded video signals is presented. The color-crossing error suppression method and system uses a first suppression technique at a pixel location for a first subset of fields exhibiting color-crossing error at a pixel location then uses a second suppression technique at the pixel location for a second subset of fields exhibiting color-crossing error at the pixel location. The second subset of fields follows the first subset of fields in the video signals.
