Delivering multimedia streaming on Internet remains several limitations, such as bandwidth fluctuations and network conjunction. We present a multimedia gateway design including dynamic bandwidth estimation, SVC extractor and buffer management to resolve the limitations. The dynamic bandwidth estimation not only selects the appropriate SVC sub-stream, but also measures the change of bandwidth and...
In this paper, we explore real time N-way video communication over enterprise networks based on scalable video coding, SVC (Scalable extension of H.264/AVC). We present a bit stream extraction strategy based on GOP size prediction and perceptual importance of temporal and quality enhancements, and validate the strategy through initial subjective testing. We also compare it with extraction based on...
Video distribution through peer-to-peer (P2P) networks using Scalable Video Coding (SVC) has been an active research. And bitstream extraction is an important issue in SVC transmission. In this paper, we propose a global optimal GOP-adaptive Rate-Distortion optimization extraction algorithm for SVC streaming multicasting over P2P networks. This method solves the problem of serving many clients with...
