| Summary: | 碩士 === 國立交通大學 === 網路工程研究所 === 101 === In recent years, it is prevalent for people to watch television shows and videos on internet. Scalable Video Coding (SVC) comes as a solution that adapts to network congestion and terminals heterogeneity. In this paper, we proposed an adaptive resource scheduling algorithm to send SVC-based videos over Stream Control Transport Protocol (SCTP) in order to play the video smoothly without interruption. We developed a probabilistic model to estimate how much bandwidth should be preserved. The preserved bandwidth is used to retransmit the important information for a reliable video transmission. On the other hand, our approach can mitigate the reduction of video resolution when some bandwidth was reserved. Our transmission scheme is compared with the widely used RTP/UDP method and standard SCTP. Simulation results show that our algorithm has 20% improvement on decodable frame rate and 13.5% improvement on the video quality compared with the standard SCTP.
