Wireless video transmission is expected to experience entire frame losses since data packets always carry a whole frame in low bitrate coding scenario. In this paper, we propose an entire frame loss recovery algorithm for H.264/AVC by using variable-size block motion vector extrapolation. At first, the proposed algorithm extrapolates MVs from available previous frames onto the lost frame and determines...
In this paper, we develop an improved error concealment scheme for entire frame loss of H.264/AVC by using variable-size block motion vector extrapolation. At first, the proposed algorithm extrapolates MVs from available neighboring frames onto the lost frame and determines the MV of each 8times8 block, for those blocks with dissimilar candidate MVs, they are divided into four sub-blocks and an re-estimation...
