Abstract

Systems and methods are provided for video conferencing geographically disperse users. Each user operates a user computer. A network connection is established among the user computers. A respective connection speed with the network connection is determined independently for each user computer. A video signal is transmitted from one of the user computers over the network connection to others of the user computers at the independently determined connection speeds.
