A generic smoothing algorithm for real-time variable bit rate video traffic
R Coelho, S Tohmé - Computer networks and ISDN systems, 1998 - Elsevier
A generic video smoothing algorithm named video step buffer (VSB) considering image
quality and delay guarantee is discussed in this paper. A wide-range scenario consisting of
different video coders and sequences were investigated in order to measure the impact of
the smoothing procedure on image quality and delay. The VSB experimental tests presented
successful results for both real and non-real-time variable bit rate (VBR) video sources. The
VSB controls rate variability while providing video source arrival prediction. The video arrival …
