A new transport framework of RTP/SCTP/IP is presented for adapting to the time-variable Internet and enhancing the reliability of transport.An improved simplified PFGS coding framework,using the standard of H.264 in base layer of PFGS,is adopted on source terminal.The steam of PFGS is separated for many sub-flows to transport by the characteristics of SCTP multi-streaming for improving the reliability and flexibility of transmission.A transport method that is a finite state machine(FSM) framework based on network bandwidth prediction over the Internet is presented.Simulation results show that this scheme can highly improve the quality of video and obtain a gain of about 0.5dB～1.5 dB in PSNR compared with the traditional network framework.Ability of adapting to network and reliability of transmission are improved rapidly.
