Abstract


In order to adapt to the heterogeneous network , and time varying transmission conditions , the video server needs to provide different quality , different sizes and different bit rate of the video stream . Generally, for a specific device or bandwidth , it is necessary to re - encode or transcode the video stream under the new configuration . This way is very expensive , server and network requirements . Scalable coding is a research hotspot in recent years , in the presence of a larger network packet loss rate to meet the requirements of the various types of video services , as well as different processing capabilities , ability , such as personal computers or mobile phones and other terminal to provide acceptable video . Collection of 14 proposals , in January 2005 , MPEG and VCEG decided Joint JVT coding as an extension of the H.264/AVC scalable and complete the amendment . After learning the the H.264/AVC codec basics and extension of H.264-SVC content , I completed a master's degree stage the following three parts : a fast mode selection algorithm using Bayesian classifier a large number of experimental data statistical results , a statistics - based fast mode selection algorithm . The algorithm reduces the enhancement layer macroblock interframe prediction, intra prediction and the use of inter-layer residual prediction candidate pattern , thereby reducing the amount of computation of the rate-distortion cost , reduce the encoding time . 2 supports H.264-SVC streaming media server the server based on open source projects LiveMedia support format video streams in H.264-SVC support simple session transmission mode , follow RTSP, SDP and RTP streaming protocols. The client using integrated open source library Open SVC Decoder mplayer player , streaming server / client application architecture , able to smoothly transfer and play video streams in H.264-SVC . Level Key Management Scheme 3. H.264-SVC video streaming video streams in H.264-SVC Level key management scheme based on cryptography grade encryption policy , discusses the key generation , distribution and dynamically adjusted. Compared with other programs , the program has a high- security , high - efficiency , low - storage , as well as the advantages of flexibility to adjust .
