Paper Abstract

Many current distributed multimedia applications such as video on demand (VOD) are designed, implemented and used on top of general purpose OS and network platforms. Within this 'best-effort' environment, applications must use adaptive synchronization protocols and balance non-deterministic behavior of the underlying OS/network subsystem to achieve user acceptance for lip synchronization of the audio-visual information. We have designed, implemented and validated an adaptive synchronization scheme integrating adaptive services and synchronization protocols to provide lip synchronization within a VOD system. Our results indicate that most of the synchronization skew values are in the user desirable range of ms and that the remaining skew values are in the user acceptable range of ms.
