An effective Video Temporal Error Concealment Method

To overcome inaccurate boundary matching algorithm bringing on the miss of the best motion vector and resulting in the bad error concealment effect, the paper proposed a novel effective temporal error concealment algorithm. Using effective temporal-spatial correlation of the motion vectors, it will adaptive construct a limited candidate motion vectors set among the motion vectors of neighboring macroblocks and extrapolated motion vectors, on the basis of it, selected the best motion vector from candidate motion vector set by using the boundary matching algorithm to conceal corrupted or lost block. The simulation results show that the proposed method reduced the miss of the best motion vector and obtained the satisfactory error concealment effective.
