Abstract	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 8×8 block, for those blocks with dissimilar candidate MVs, they are divided into four sub-blocks and an re-estimation method is implemented on every sub-blocks. Then, a more complete motion vector field is obtained by u sing median filtering. At last, the blocks without extrapolation MVs are concealed by using linear interpolation algorithm. Experimental results show that this method can alleviate the shortcomings of the fixed-size method effectively and provide better performance than other concealment methods.
