Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Aimed this problem, this paper proposes an adaptive concealment order based on well know Boundary matching algorithm [7, 8]. The concealment order is carefully chosen according to a lost MB's priority, which is formulated considering 2 factors, MV (motion vector) distribution in the lost MB's area, and its available neighborhood information. Compared with Chen's work [11], the experiments show our proposal always achieves better performance of video recovery under different packet lost rate channel.
