    Abstract: A position of one or more video cameras is determined. The position of one or more video cameras is communicated with a video communication application. A position of one or more video windows is controlled from the position of one or more video cameras, where controlling the position of one or more video windows further involves one or more video windows being positioned at a position closest to one or more video cameras.

    Abstract: Methods and apparatus for compositing multiple video streams onto a background image having at least one object while keeping at least one of a proper perspective, order, and substantial alignment to the object of the multiple video streams based on the rules of a common layout. The background is defined as a meeting space that fills in gaps between the multiple video streams with appropriate structure of the object. The background creates the context of the meeting space.

    Abstract: Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a distributor communicatively coupled to a first network and a second network having different network characteristics from the first network, the distributor configured to receive first media streams from at least one first network node, and to transmit the first media streams to at least one second network node; and a management subsystem adapted to dynamically configure a topology of a virtual collaborative event, wherein configuration of the topology includes a determination of media stream connections among the distributor and the at least one first network node based, at least in part, on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one first network node and the at least one second network node.

    Abstract: A coordinated media control system includes a node manager, a device control system, and a device. The node manager is operatively connected to a first node. The device control system is operatively connected to the node manager. The device is operatively connected to the device control system. The node manager is configured to establish and coordinate media streams for transmitting media from the device to a second node or for receiving media to the device from the second node.
