Abstract :
Mode selection algorithms for spatiotemporal concealment of missing macroblocks (MBs) in a corrupted video stream are presented. The proposed algorithms employ the motion compensated temporal activity in the neighbourhood of each missing MB for switching between concealment methods. Results show gains of up to 4.6 dB for a 10% packet error rate relative to other mode selection methods
