Abstract

In this paper, a redundant macro block coding with texturebased selective boundary matching algorithm (RMB-TSBMA) is introduced to improve the video quality. Different from texture-based selective boundary matching algorithm (TSBMA), the algorithm is more suitable for frame based recovery. The RMB coding encodes the information of some essential blocks. When a frame gets lost, we can first decode RMBs, and then neighboring MBs with TSBMA, so that the RMBs can provide the correct position for boundary matching to get better visual quality. The influences of the RMB number, and the reordering method are also discussed. Compared to the other algorithms, the proposed RMBTSBMA performs better than conventional method of temporal direct mode (TDM) by over 3dB PSNR at the packet loss rate 10%.
