ABSTRACT:
An adaptive error concealment system uses either a horizontal or vertical average as a replacement pixel for an erroneous pixel. The choice is dependent upon the amount of horizontal information in at least one adjacent horizontal line. This avoids errors if certain horizontal or vertical stripe patterns are present in the video signal.
