Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Such degradation even becomes worse in 1Seg video broadcasting application, which is widely used in Japan and Brazil for mobile phone TV service, where errors are drastically increased and huge conjunctive areas inside a picture may be corrupted. In this case the error concealment order -to decide which MB should be concealed earlier -may highly influence image quality. Aimed this problem, this paper proposes an adaptive concealment order based on well-known Boundary Matching Algorithm (BMA). The concealment order is carefully chosen according to a lost MB's priority, which is formulated considering a concealed MB's side match distortion: an MB with smaller distortion should be concealed earlier compared with an MB with larger distortion. As for formulation of side match distortion, not only the current corrupted MB's, but also the neighboring MB's, which is caused by error propagation, are included. Compared with reference work [10], the experiments show our proposal achieves better performance of video recovery under different error rate channel in 1Seg application.
