摘要
移动流媒体业务是当今移动运营商的重要增值业务。连续性、实时性、时序性是流媒体数据流的三大特征。给出典型的移动流媒体系统结构图,移动流媒体系统主要由移动终端、移动通信网、流媒体服务器三部分组成。详细分析系统各构成部分的功能以及移动流媒体服务器的RTSP(real time stream protocol),SDP(session description protocol),RTP(real time transport protcol)/RTCP(real time transport control protocol)协议,为移动流媒体服务器的设计奠定了理论基础。
Mobile streaming media service is an important value added service for today’s mobile operators. Continuousness, real time, scheduling are three main characteristics of streaming media data stream. A typical mobile streaming media system structure diagram is proposed in this paper. Mobile streaming media system is mainly composed of mobile terminal, mobile communication network, streaming media server. Then the function of every part of the system and RTSP, SDP, RTP,RTCP protocol, are introduced in detail.The above research establishes a theoretical foundation for the design of streaming media server for mobile.
