| 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. |
