摘要
随着人类社会的信息化,多媒体应用已经渗透到人们生活的各个领域。多媒体传输过程中,误码的产生、数据的丢失总是难以避免的,而且极易发生扩散,从而导致视频品质严重下降。介绍了H.264/AVC标准的编解码技术特点,分析讨论了H.264网络传输机制,并且重点对视频压缩码的差错控制技术进行研究。
In recent years,with the development of electronic technology,computer science and network technology,video communication on the network is applied widely.With the wide application of video communication,errors and losses of video data are inevitable,resulting in a serious decline in video quality.This paper introduces the new technologies of H.264/AVC standard differing from the previous versions,makes a study of the resilience tool in H.264 such as flexible macroblock ordering（FMO）,parameter sets,data partition,and describes different modes of FMO in detail.It also puts the emphasis on the study of the temporal concealment.
