摘　　要：在网络环境下视频能实时传输,如在视频会议系统中,最小的延时是保证参会者很好交互的重要条件.本文对几种FGS层编码的低延时应用的方案进行了评述,并对各种方法进行了测试,给出了试验结果.最后指出了H.264SVC扩展中FGS层编码对于低延时应用的发展方向.Video stream can make real-time transmissions over Internet. Minimizing end-to-end delay is critical for ensuring good interaction among the participants. In this paper, we have given the detailed account of several methods of low-delay applications of FGS coding, with each method analyzed, and pros and cons compared. In the end, the issues are addressed concerning future R＆D trend of the low-delay applications of FGS coding in H.264 SVC.
