Abstract

Variable bit rate (VBR) video is very bursty and its transportation over ATM networks is problematic because bandwidth has to be reserved in advance. Studies have shown that VER video exhibits statistical self-similarity: it displays structural similarities across a wide range of time scales. To date, studies on the burstiness of MPEG compressed bitstreams have been conducted on the video part only; the audio part has been neglected because of its constant bit rate nature. Furthermore, the change in burstiness of MPEG data which occurs after they have been converted to MPEG-2 transport and ATM bitstreams has not been investigated; a considerable amount of overhead bytes is introduced duringthe conversion. This paper reports on a study on the burstiness of combined MPEG-1 audio and video bitstreams as found on commercial Video CDs, and the burstiness of these combined bitstreams after they have been converted to MPEG-2 transport and ATM layer bitstreams. We found that there is no increase in burstiness in both situations. (C) 1998 Elsevier Science B,V.
