Abstract
In a multimedia application, the need for synchronization between audio and video became necessary, mainly in a distributed environment to ensure a quality of service. In this paper, we present a tele-teaching application experiment and simulation results, using TCP/IP with LAN Emulation (LANE) and native ATM networks, performances. We show that the multimedia synchronization is respected. Simulations show that ATM with its possibilities for high bandwidth and bounded delay, is ideally suited as a technology capable of supporting video services and guarantee their QoS. The use of MPEG-4 video coding allows to consume low bandwidths. This is suitable for IP but not necessarily for ATM network. Therefore, in order to allow interoperability of the tele-teaching application over IP and ATM networks we chose MPEG-4 technique.
