Abstract

Multimedia streams such as audio and video impose tight temporal constraints for their presentation. Often,related multimedia streams, such as audio and video, mustbe presented in a synchronized way. We introduce a novelscheme to ensure the continuous and synchronous deliveryof distributed stored multimedia streams across a communications network. We propose a new protocol for synchronized playback and compute the buffer required to achieveboth, the continuity within a single substream and the synchronization between related substreams. The scheme is verygeneral and does not require synchronized clocks. Using aresynchronization protocol based on buffer level control, thescheme is able to cope with server drop-outs and clock drift.The synchronization scheme has been implemented and thepaper concludes with our experimental results.
