Video Error Concealment Technique Based on Side Matching

A newerror concealmentmethod using pre-concealment process (PREP) and search concealment (SC ) was proposed. This method uses surrounding motion vectors (MV) as many as possible by pre- processingadjacent MBs(Macroblock, MB), and then finds the best MV s by performing an additional search process. Simulation results based on JM1.4 CODEC of JVT (Joint Video Team) show that both PREP and SC significantly improve the reconstruction of video quality and much better results can be achieved by combining the newtechnique with no-waiting ARQ (NWARQ) technique.
