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 Protoco(lRTCP),实时传输控制协议;Real Time Streaming Protoco(lRTSP),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。
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.
