A temporal error concealment (TEC) algorithm is proposed, which is specifically designed for the data partitioning profile of MPEG-2 and for MPEG-2-compatible scalable schemes. Among the four methods to produce a scalable video bitstream for MPEG-2, the data partitioning profile is chosen for its simple implementation and high overall video quality due to reduced overhead information. The proposed TEC algorithm, namely MCTEC-DISP, applies also on I-picture since it operates on the motion vectors of the current reference P-frame. Subject to the hypothesis of motion continuity, MCTEC-DISP improve layered MPEG-2 video quality in the presence of packet losses. This is particularly important when layered video is transmitted over dual- priority networks. The algorithm presents a reduced computational complexity with respect to similar TEC schemes and it is not designed for post-processing implementation, but it operates during the decoding process for real-time decoding.
