Multimedia applications including video data require the smoothingof video playout to prevent potential discontinuity. In this paper, wepropose a dynamic video playout smoothing method, called the Video Smoother,which dynamically adopts various playout rates in an attempt to compensatefor high delay variance of networks. Specifically, if the number of framesin the buffer exceeds a given threshold (TH), the Smoother employs a maximumplayout rate. Otherwise, the Smoother uses proportionally reduced rates inan effort to eliminate playout pauses resulting from the emptiness of theplayout buffer. To determine THs under various loads, we present an analyticmodel assuming the Interrupted Poisson Process (IPP) arrival. Based on theanalytic results, we establish a paradigm of determining THs and playoutrates for achieving different playout qualities under various loads ofnetworks. Finally, to demonstrate the viability of the Video Smoother, wehave implemented a prototyping system including a multimediateleconferencing application and the Video Smoother performing as part ofthe transport layer. The prototyping results show that the Video Smootherachieves smooth playout incurring only unnoticeable delays.
