摘要： A coding and decoding method and device for improving video error concealment is disclosed in the present invention. The coding method includes the steps of: obtaining a macro block smoothness information of a macro block in a video stream, which indicates whether the boundaries of the macro block are smooth or not; and coding the macro block smoothness information into a coded video stream. The decoding method includes the steps of: determining whether the boundaries of a lost macro block are smooth or not according to the macro block smoothness information of the lost macro block in a video stream; smoothing the displacing macro block for the lost macro block if the boundaries are smooth. The smoothed displacing macro block is more similar to the original macro block, thereby the whole image is more natural with a small coding cost but a highly improved image quality; further, the calculation amount thereof is small, and the cost to realize it is relatively low.
