The authors propose a classification for the scene detection techniques which are commonly used in variable bit rate (VBR) video traffic modelling. Using real video traces we show that scene durations follow heavy-tailed distributions. This heavy-tailed nature is proved to be independent of the technique or the threshold used for the scene detection. This invariant property of video sequences offers a physical explanation for the existence of long range dependence (LRD) in video traffic.
