Abstract :
The pervasiveness of the Internet, the continuous increase in the desktop computing 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 audio and video streams over a jitter-induced network, and proposes a new scheme using a buffer-based request/reply model to provide a high quality audio-video playback with optimised network utilisation. This scheme has been adopted as a jitter concealment tool under DAVIC 1.5 baseline document 15z07r40
