Abstract: In order to deal with heterogeneity of the terminal and the network in the mobile Internet, the H.264/SVC is applied into the mobile video-on-demand service, and a bit stream self-adaptively broadcast system based on SVC is implemcented. With the aid of JSVM, the generation of scalable video with different space, time and quality layers is implemented. On the basis of VS, the dynamic switching is simulated in bit rate of scalable video in the process of transmission and broadcast. By analyzing the sub-layer stream, we confirmed that scalable video has a large span on bit rate and the quality of decoded video is good, and tested the advantages of H.264/SVC in mobile Internet video services, and the feasibility of the application.
