Abstract
In this paper several video conferencing systems are discussed. These include single person-camera, voice-switched, split-screen, continuous presence, and virtual space systems. Special emphasis is placed on the more recent video conferencing systems, i.e., the continuous presence and the virtual space systems. The role of digital signal processing in the video conferencing environment is discussed. The interaction between service definition, the video conferencing system, and the digital signal processing requirements is highlighted.
