Abstract: AVS is the second generation source coding-decoding standard whose intellectual property is owned by China.Compared with coding-decoding standard MPEG，H.264/AVC，AVS has several advantages such as good technology performance，low implementation complexity and clear intellectual property.Through deep study of AVS coding format，this paper develops a streaming media system supporting AVS video transmission using RTP/RTCP/RTSP protocols，including AVS server and AVS client.The system can be used in video monitoring and video on demand and has a promising future in application.At last，the transmission of AVS file is simulated using NS2 and the Peak Signal to Noise Ratio（PSNR） of Y component is given.

摘要： AVS是我国具有自主知识产权的第二代音视频编解码标准，与MPEG、H.264/AVC等编解码标准相比，具有技术性能先进、实现复杂度低、知识产权清晰等优点。通过深入研究AVS编解码格式，利用RTP/RTCP/RTSP（Real-time Transport Protocol（RTP），实时传输协议；Real-time Transport Control Protocol（RTCP），实时传输控制协议；Real Time Streaming Protocol（RTSP），实时流协议）协议开发了支持AVS标准的流媒体传输系统，包括流媒体服务器和客户端。该系统可以应用于视频点播、视频监控等相关领域，具有广阔的应用前景。最后，利用NS2做了传输AVS文件的仿真，并给出了Y分量的峰值信噪比。
