In this paper, we propose a temporal error concealment (EC) method which preserves image continuity across the boundaries. For temporal EC, various block matching-based algorithms are researched to refine the corrupted video. However, existing temporal EC methods are suffered from the blocking artifacts in visual quality since those methods do not consider the edge orientation at the macroblock border. To solve these problems, we propose new EC technique using edge direction matching to preserve the edge information while alleviating the blocking artifacts. Experimental results show that the proposed algorithm yields superior subjective and objective video quality than the conventional algorithms.
