Abstract
A receiving apparatus comprises a receiver for receiving a video signal, an output for outputting the video signal to a screen, storage device or further terminal; and a concealment module for applying a concealment algorithm to a lost area of the video signal. The concealment module is configured to determine an estimate of concealment quality selectively directed toward a region of interest within the area in question, and based on this estimate to determine whether or not to apply the concealment algorithm.
