摘要：

The paper presents a tempral error concealment algorithm suitable for the H.264 video coding standard for error code and packet loss issues of video compression data in network transmission. The algorithm determines the correct mode for the lost block based on the modes of neighboring macroblocks, and according to the motion of the block, selects the most appropriate motion vector to recover the damaged area among a set of candidate motion vectors. The experimental results show that the complicated motion region can be well recovered with the proposed algorithm and good results can be achieved for video under various conditions of packet loss rate.
