N2 - Error concealment (EC) techniques are often adopted at the decoder side to improve the reconstructed video quality, in case of some information is lost during transmission on a bandwidth limited wired networks or wireless networks with error-prone channels. In this paper, a global motion/local motion (GM/LM) based error concealment technique is proposed for transporting MPEG-4 advanced simple profile (ASP) coded video over high lossy and noisy networks. Different from the conversional error concealment methods, which make full use of the temporal spatial information to recover the error macro-blocks, the proposed GM/LM based method can efficiently improve the reconstructed video quality by using the redundant information which sent at encoder side. The redundant information consists of the global motion parameters and global motion compensation/local motion compensation (GMC/LMC) map information for each macro-block (MB) of P-frames. Comparison results with different error concealment methods on different video sequences show the effectiveness of the proposed GM/LM based error concealment method
