Abstract:
The highly error-prone nature of wireless environments and limited computational power of mobile devices necessitates the implementation of robust yet simple error concealment in H.264/AVC. We propose a new and effective error concealment algorithm for intra-coded frames that utilizes the temporal redundancy in a wireless video bitstream. The proposed concealment method supports both raster scan and FMO type slices. Performance evaluations show that our approach achieves significant improvement over existing methods in both PSNR and subjective picture quality.
