Abstract
A new approach is proposed that contemplates systems and methods to support the operation of a Virtual Media Room or Virtual Meeting Room (VMR), wherein each VMR can accept from a plurality of participants at different geographic locations a variety of video conferencing feeds from video conference endpoints that can be either proprietary or standards-based and enable a multi-party video conferencing session among the plurality of participants by composing one composite audio and video stream for each of the participants. Each single VMR can be implemented across an infrastructure of globally distributed set of servers/media processing nodes co-located in Points of Presence (POPs) for Internet access. Each VMR also gives its users a rich set of conferencing and collaboration interaction hitherto not experienced by video conferencing users.
