• Synchronization of media streams is recognized as an important requirement not only in media retrieval such as a video on-demand service but also in groupware such as a remote conferencing system. In a remote conferencing system, synchronization is more complicated because Live Media Streams (LMS) such as the live raw voice of some participants must be taken into consideration as well as Retrieved Media Streams (RMS) such as media streams retrieved from video equipment. In this paper, we propose a mechanism to synchronize RMSs and LMSs in a remote conferencing system DMSIC (Distributed Multimedia System with Interactive Control) which has been implemented on UNIX workstations connected by Ethernet. In this mechanism, synchronization among RMSs (we call it RampR synchronization) is kept by maintaining the Current Presentation Positions (CPP) on Media Buffers (MB) close to the Ideal Presentation Position (IPP). Synchronization among RMSs and LMSs (we call it RampL synchronization) is kept by adjusting the IPPs among multiple nodes. We have implemented the synchronization mechanism in DMSIC to confirm the effectiveness of it.
