Background technology
Stream media technology refers to that multi-medium data is transmitted with streaming manner by network from service end to client, together
When, client can receive multimedia data stream while the technology played out.RTP (Real-
TimeTransportProtocol, RTP)/real-time streaming protocol (RealTimeStreamingProtocol, RTSP) and HTTP be
Two kinds of fluidization techniques being widely used at present.Because RTP/RTSP fluidization techniques can support live broadcast service well, and F.F.,
Rewind etc. operates, at present, the interactive individual character TV in part（InteractivePersonalityTelevision,IPTV）It is and big
Partial video program uses RTP/RTSP fluidization techniques, and RTP/RTSP fluidization techniques are normally based on RTP/ UDPs
（UserDataProtocol,UDP）Transmission, server is by code rate push code stream.But RTP/RTSP fluidization techniques are to net
The adaptability of network is poor, and the packet loss of network, shake easily cause the loss of video message, when in turn resulting in user's watching video
There is mosaic and the phenomenon paused, if however, fluidization technique used by current IPTV and video frequency program carried out big
The replacing of scale is instead of RTP/RTSP, not only to need largely to the retrofit work of existing network, and it is original to lose RTP/RTSP
