摘要

There are several real-time dynamic adaptation mechanisms that exist today for improving end user perceived quality for IPTV services in wireless local networks. However, an adaptation scheme based on stream priorities, combined with terminals characteristics and the expected service quality levels, has not been explicitly considered by the existing approaches. This paper proposes a novel solution - the intelligent Prioritized Adaptive Scheme (iPAS) for adapting the encoding and transmission bitrates of video traffic based on stream priority and current network bandwidth resources as estimated by the bandwidth estimation technique, iBE. Results show how iPAS outperforms an equal priority solution in terms of distribution of both bandwidth between streams with different requirements and associated user perceived quality.
