Claim:
1. A receiving apparatus comprising: a hardware receiver for receiving a video signal; an output device for outputting the video signal to one or more of a screen, storage device or further terminal; and a concealment module stored on one or more computer-readable storage memories and configured to be executable to apply a concealment algorithm to an area of said video signal having lost data, the concealment module being configured to determine an estimate of concealment quality selectively directed toward a region of interest within said area, the estimate based at least in part on a measure of difference between corresponding pixels in different frames of the video signal that surround a block at least on three sides, the block representing the region of interest in each of the different frames, the estimate excluding pixels on a side of the block different than the at least three sides responsive to determining that the excluded pixels are in another block having non-linear motion beyond a threshold of linearity, the concealment module configured to determine whether or not to apply the concealment algorithm based on said estimate.
