A Pervasive Temporal Error Concealment Algorithm for H.264/AVC Decoder

In real-time video transmission over error-prone network, the packet loss cannot be avoided which causes the video quality reduction in the destination. In this paper, we propose a pervasive temporal error concealment (PTEC) algorithm for H.264/AVC Inter frame decoding to eliminate the error effect for Human Visual System (HVS). To increase the error concealment (EC) accuracy, the 4x4 block size is used as the basic motion vector (MV) recovery unit, and the MV of the lost macroblock (MB) is recovered by employing the MV information of the neighboring intact MBs. The simulation results show that the proposed algorithm can achieve better EC performance compared with the existing TEC methods. Because of its simple composition, it is pervasive to be used in the real-time multimedia communication systems with the video coding standard H.264/AVC.
