Abstract

According to one embodiment of the present invention, a method for displaying a videoconference includes receiving a first video feed. The first video feed includes a first plurality of video signals, each video signal from at least one source and originating from one or more sites. The method also includes assigning for a videoconference each video signal of the first plurality of video signals to a zone of a plurality of zones of a display window. Each zone of the plurality of zones is able to display one video signal at a time. The method further includes, for each zone of the plurality of zones of the display window to which more than one video signal has been assigned, switching the current video signal to be displayed in the zone to another video signal assigned to the zone based on a switching protocol.
