Characterization of video conferencing traffic in ATM networks

Abstract

In order to effectively transport digital compressed video in evolving high speed communication networks such as ATM-based broadband integrated services digital networks (B-ISDNs), it is essential to understand the characteristics of the video traffic. The nature of the video traffic depends primarily on the video source, the contents of the video, and the coding algorithm that removes the redundancies for efficient transmission over networks. In this paper, we study and characterize the video information in a video conference environment. The video information is encoded by using a subband coding scheme.
