Abstract
When audio-video is in the process of wireless transmission, it is prone to losing packets. As a solution, this paper presents an adaptive spatial-temporal error concealment scheme based on H.264/AVC. It can adaptively select the spatial error or temporal error on the basis of change in the surroundings, in which temporal error finds the best motion vectors with the spatial-temporal boundary matching, and spatial error concealment switches between the weighted average method and improved directional interpolation. Experimental results indicate good performance of the proposed scheme for error concealment.
