Abstract

In this paper, we propose a new temporal error concealment method for H.264/AVC coded video using the existing information of neighboring macroblock modes from the coded bit-stream. The lost macroblock is partitioned into eight possible types, and each partition is concealed with an estimated motion vector giving a smoother concealment. An overlapped block motion compensation technique is further used to avoid spatial discontinuities in the concealed regions. This helps to minimize the structural degradations and the blocking artifacts. Experimental results show that the proposed scheme achieves higher video quality values than the existing schemes.
