In order to improve the decoding performance of digital satellite set-top boxes, this paper proposed a directional boundary matching algorithm on temporal domain for H.264, it considers using the spatial smoothing of video images and the movement consistency in neighbor macro-blocks to restore the damaged macro-block, with pixels matching in three directions on the boundary. On this basis, a adaptive error concealment algorithm of multi-mode is proposed, which avoids the judgment of the partition mode of damaged macro-block. Experimental results show that when in the same case of packet loss, compared with the traditional concealment algorithms, the algorithm proposed in this paper has better performance in the improvement of PSNR and visual effect.
