Abstract
The lost of a block in an intra frame will damage the video quality extremely. In this paper, an efficient concealment for intra frame is proposed based on the spatial and temporal domain interpolation. For spatial domain concealment, the weighted interpolation (WI) and texture prediction (TP) are adopted according to the blocks surrounding the damaged macroblock (MB). If the blocks surrounding the damaged MB are all available, the TP method will be used. Otherwise the WI method will be used. For temporal domain, motion vector copy (MVC) is adopted for the interpolation. Simulation results have shown that the proposed method can significantly improve the quality of the video.
