Abstract
Video services to the home are among the driving applications for emerging broadband networks. For residential services to be viable, video quality must be comparable to broadcast video. Video compression technology has well defined standards for high quality video (MPEG). Suitable video delivery techniques are however still under investigation. We consider the problem of delivering constant quality video using variable bit rate encoding. A traffic model is proposed for three different encoding types (H.261, MPEG2: one and two layer). These models are suitable for either stored or real-time video. The statistical multiplexing efficiency of these video sources and call admission based on leaky bucket traffic parameters are evaluated. Two layer encoding is shown to have significantly better statistical multiplexing gains than one-layer video, when the network admits calls based on a leaky-bucket characterization.
