Abstract :
This paper compares four schemes of lip synchronization control between voice and video for stored media transmission. Two out of the four interleave voice and video to form a single transport stream for transmission (single-stream approach). The other two set up separate transport streams for the individual media streams (multi-stream approach). In each of the two approaches, we have the alternative of exerting the control or not. We implemented the four schemes on an ATM LAN and on an interconnected ATM-wireless LAN under the TCP protocol. The mean square error of synchronization, total pause time, throughput and total output time were measured in each of the schemes to find out which scheme is the most suitable for a given condition of the underlying communication network and traffic
