Abstract

This paper reports experimental results of a media synchronization mechanism which was proposed by the authors, focusing on the graceful recovery scheme. The proposed method consists of intra-stream and inter-stream synchronization mechanisms. The inter-stream synchronization control is performed after the intra-stream synchronization control overeach media unit (MU) such as a video frame. Then, whether the intra-stream synchronization is still maintained or not is checked. In the experimental system, video and voice stored in a source workstation are transferred to a destination workstation via an FDDI network, and thenthey are synchronized and outputted at the destination (i.e., lip-synch). At the transmission of each MU, we simulate network delay jittersby generating a pseudo-delay which is exponentially distributed. Using the system, we have confirmed the validity of the mechanism. We alsoclarify how to set the threshold and parameter values defined in the mechanism by evaluating mean square error and average MU rate or by subjective assessment. Furthermore, we demonstrate that the intra-streamsynchronization control for each streams in addition to the inter-stream control is necessary for high quality synchronization.
