Abstract: Systems and methods for performing videoconferencing using endpoints with multiple monitors and multiple cameras are disclosed herein. These endpoints are comprised of, where each node is comprised of a control unit and one or more node units, each connected to at least one monitor, camera, speaker, or microphone. Video is encoded using scalable coding, and endpoints are connected to each other over a network using an SVCS. Algorithms are described for layout management, tagging of individual streams, and use of tags for dynamic and prioritized layout management.

Abstract: Disclosed is a method of establishing a media call wherein a data stream contains a call control channel and one or more media channels. A network connection between a call control entity and a far end device is established wherein the connection conveys the call control channel. This connection typically utilizes a control protocol such as SIP or H.323. A network connection is established between the call control entity and a media entity, typically using an XML protocol. This connection between the call control entity and the media entity is used to prepare and direct the media entity to receive incoming media. The call control device directs the far end device to establish a media channel network connection between the far end device and the media entity, typically using RTP. By separating the call control channel from the media channel(s), a non-media device, such as an IP telephone can be integrated into a media conferencing experience.
