  Abstract

If an error occurs during transmitting compressed video through the communication network, error concealment is needed to prevent error propagation and to improve quality. In this paper, we propose the high performance temporal error concealment algorithm for H.264/AVC. The proposed algorithm uses the property that the motion vector of the error macroblock between the motion vectors of the neighboring macroblock have the high similarity to select a group of candidate motion vectors, when an error occurs in the inter-coded frame. Next, weighting overlapped boundary matching algorithm using the credibility of decoded pixels without errors selects the best candidate motion vector among a group of candidate motion vectors. The experimental results show that the proposed algorithm improves PSNR up to 3.02 ㏈ compared with the previous algorithms of H.264/AVC.
