Mobile Streaming Media Server Key Technologies And Systems To Achieve

With the rapid development of mobile communication, people not only need text,voice,image, but also need multi-media information. The 3G is not only come from TDMA, but from CDMA, which make the transmission rates reach at least 144K. According to the ITU-T, the translate rates of 3G must arrive at 144K in the house at least ,but the rates may arrive at from 384K to 2M in the various technology . Under the surroundings of 3G technology rapid development, mobile operator may service for mobile clients wherever and whenever. Mobile streaming media plays an important role in the various mobile increment application which is different from 2G. Design and implement of mobile streaming media sever which is the core equipment in the mobile streaming media system is a very big challenge because wireless channel have the characteristic of high VBR,high transmission delay and varied transmission rate. Base on above all, this paper analyses several key technologies of mobile streaming media server. At first, the paper analyses the steaming media service of 3GPP, which have a look of the mobile streaming media requirement of 3GPP. Secondly, the paper analyses the structure of mobile steaming media system, and indicate the position of mobile streaming media sever in the moble steaming media system, and put forward several key technogis of mobile steaming media server. The paper analyses the several key technogis of mobile streaming media server in particular.including mobile streaming media transmission control protocol,mobile streaming media encoding and decoding,mobile streaming media QoS。And mobile streaming media transmission control protocol includes RTSP protocol,RTP/RTCP protocol, and mobile streaming media encoding and decoding includes FGS and PFGS, and mobile streaming media QoS control strategy including mobile streaming media QoS research background,mobile streaming media QoS control strategy on the application level ,and put forward a end-end QoS control strategy of mobile streaming media. In the end, the paper analyses the design and implement of mobile streaming media sever in particular, and test the capability of mobile streaming media server and analyses the test result.
