An efficient multi-hypothesis error concealment algorithm for H.264 video is proposed in this work. The proposed algorithm temporally conceals a lost block by combining several hypothesis blocks in the previous frame. We investigate the error recovery performance according to the number of hypotheses and the weighting coefficients. Simulation results demonstrate that the proposed algorithm provides better performance than the conventional error concealment algorithm, although the additional complexity requirement is negligible.
