Abstract
In a system that divides data frames into blocks and codes at least some of the blocks by intra-frame coding, errors in decoding these blocks are concealed by two methods: replacement of the erroneous block by its DC component, and replacement of the erroneous block with data from the preceding frame. The selection between these two methods is made according to one or more of the following criteria: reliability of the DC value; motion-vector size; motion-vector change from the preceding frame; and whether intra-frame coding was selected or forced. These selection criteria improve the probability of successful error concealment.
