Abstract
In this paper, we propose a practical design and implementation of multi-channel High Definition (HD) and Standard Definition (SD) MPEG-2 video streaming system using server-side video rate adaptation and rate shaping over digital community network. For video rate adaptation, we employ Program Clock Reference (PCR) embedded in the MPEG-2 streams to enhance packet timing control precision and regulate the transmission rate in a refined way. For rate shaping, we introduce Traffic Control (TC) ingeniously to separate streams of different channels at the network card of server and avoid bandwidth contesting between them. Experimental results show that the proposed system can mitigate the quality degradation of video streaming due to the fluctuations of time-varying channel and simultaneously support 33-channel HDTV streams.
