T.120/H.32x-based multimedia conferencing design

Multimedia conferencing technology is becoming increasingly important, as it enables people who are located in different cities (or countries) to share as well as interact with their data, comments, images, and video pictures. This paper introduces the multimedia conferencing standards, such as ITU-T T.120, T.130, H.320, H.323, and H.324, which comprise the core technologies for multimedia conferencing. The paper discusses interoperability and compatibility issues which arise from the deployment of different vendor applications. The paper also presents a proposed multimedia conferencing system with H.32X standard capabilities, which is designed to facilitate interoperability and compatibility between different platforms
