摘要: 3G mobile standard offers unprecedented high speed digital service that can carry multimedia traffics such as video streaming. The distributed system buffers in the conventional client-server architecture absorb the fluctuations of channel conditions such as bit rate variations, delays and jitters. To enable easy control for the 3G system, MPEG committee is developing scalable video coding technology that provides flexibility for transmission over wireless networks. This paper will address issues in controlling these buffers that can impact and benefit the end-to-end system performance using the novel scalable video technology. specifically, we will explore the effects of diverse channel characteristics on the buffers performance tolerance, and its impact on the quality of service. A novel model-based Adaptive Media Playout (AMP) buffer control is proposed to mitigate the risks of buffer outage.
