A DAVIC-based video-on-demand system over IP networks

The pervasiveness of the Internet, the continuous increase in the desktop c omputing power coupled with the availability of relatively inexpensive MPEG -2 codecs have brought MPEG-2 based, high quality video communication close to the desktop computers. This paper examines the problem of synchronising the server and the receiver clocks in the transmission of MPEG-2 encoded a udio and video streams over a jitters-induced network, and proposes a new s cheme using a buffer-based Request/Reply model to provide a high quality au dio-video playback with optimised network utilisation. This scheme has been adopted as a Jitter Concealment Tool under DAVIC 1.5 baseline document 15z 07r40.
