Research of video communication technology in H.264/AVC

The new H.264/AVC standard is designed to support a broad range of applications.It provides mechanisms for coding video that are optimized for compression efficiently and aim to meet the needs of practical multimedia communication applications. Some key aspects which are for robustness to data errors/losses and flexibility for operation over a variety of network environments in video communication, including parameter set structure, NAL unit syntax structure,redundant slice and flexible macroblock ordering are discussed in this paper.
