Video Conferencing Over ATM Networks

Greg Smyth

Abstract: The following thesis investigates the design and implementation of a videoconferencing system utilising an ATM network.
The theory of digital video is discussed, comparing the colour spaces or RGB and YUV, and the different video capture methods. The pro and cons of CCD and the relative new comer CMOS cameras are also look at.
With digital video requiring high bandwidth’s in the order of 196 Mb/sec, the ATM standard and the PCI bus are overviewed to give an understanding of why these were chosen and there benefit to the design.
The final design was shown to have inadequacies in relation to the inefficient use of network bandwidth and that the overall design need the addition of audio to become a real videoconferencing system.
