Abstract :
This paper presents measured performance of a media synchronization mechanism which was proposed by the authors, focusing on the quick recovery scheme. The mechanism has been implemented for lip-synch on an experimental system, which consists of a source-destination workstation pair connected via an FDDI network. Video of a speaker and her voice stored in the source workstation are transferred to the destination workstation, and then they are synchronized and outputted at the destination. Using the system, we have confirmed the validity of the mechanism. We clarify how to set the threshold and parameter values defined in the mechanism by evaluating its performance. We also demonstrate that the intra-stream synchronization control for each stream in addition to the inter-stream control necessary for high quality synchronization
