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...
This paper evaluates the performance of a zero reference metric used in objective measurement of the quality of video which has been transcoded at various bit rates to suit the needs of the 3G mobile environment. This Zero reference metric (AVQ) has been shown to exhibit a high correlation with Mean Time Between Failures (MTBF) which is a functional measure of video quality representing how often...
