With the growth of video conferencing, the need for multipoint conferences is also growing. In a multipoint videoconference over a wide‐area network, the users are connected to a multipoint control unit (MCU) in a central office. A video bridge in the MCU combines the input video streams into a suitable format for presentation. In this article, we discuss various approaches of video bridging for continuous presence multipoint video conferencing. We also discuss the video quality issues and describe some multipoint video bridge prototypes we have developed. © 1997 John Wiley & Sons, Inc. Int J Imaging Syst Technol, 8, 427–431, 1997
