The next-generation video coding standard, called High Efficiency Video Coding (HEVC), obtains high efficiency compression by using variable size coding block based on quad-tree structure. However, when HEVC stream is transmitted through the network, the burst loss of data packet may lead to the loss of the whole frame. By analysis of the texture features of video, motion vector (MV) extrapolation based on variable size coding blocks is proposed in this paper to recovery the lost frame fast and effectively. Experimental results show that the proposed method can reduce computational complexity effectively, compared to traditional error conceal algorithms in case of the similar PSNR.
