Robust H.264/AVC video coding with priority classification, adaptive NALU size and fragmentation

In this paper, we discuss a novel priority assignment and packetization scheme to transport H.264/AVC video packets over wireless networks. Specifically, we discuss a comprehensive packet priority assignment scheme for unequal error protection, followed by the use of adaptive network abstraction layer unit (NALU) sizes and NALU fragmentation schemes. These schemes use the standard-compliant decoder with various H.264/AVC error resiliency features. Our simulation results demonstrate that these schemes improve the PSNR performance of test video sequences in the presence of packet losses.
