摘要：

结合当前最流行且得到业界广泛认可的嵌入式数字视频系统框架——达芬奇技术框架，基于达芬奇技术典型处理器TMS20DM6446平台构建流媒体服务器，用AVS、H.264和MPEG4做视频压缩，用G.711和G.728做音频压缩算法，用SIP做访问控制协议，用RTP/RTCP和UDP等做媒体控制和传输协议；完成具有完整实时编码、录像存储、实时监控、远程控制等功能的网络音视频监控系统。该系统具有高性能、高编码效率、低成本、低延迟、强实时性等特点，能够在广域网上流畅运行。

Abstract: Based on the most popular and widely acknowledged framework for embedded digital video system—Davinci framework，this paper adopts Davinci technology typical processor—TMS320DM6446 as hardware platform，constructs a streaming media server.The streaming media server system can implement real-time coding，video storage，real-time supervision and remote control，which makes use of H.264，MPEG4 and AVS as video compression standard，the G.711 and G.728 as audio compression standard，the SIP as access control protocol，the RTP/RTCP/RTSP and UDP as multimedia control and transport protocol.The system has high performance and coding efficiency，low cost and delay time and hard real-time advantages，and it can affluently run in wide area network.

Key words: embedded multi-core system, Session Initiation Protocol（SIP）, streaming media server, Davinci technology
