Abstract: An event management system is configured to receive information that indicates a presence of an attendee of a collaboration event at a first location that is not specified by a registered event specification corresponding to the collaboration event and provide information to the attendee to direct the attendee to a second location with an endpoint for connecting to the collaboration event.

Abstract: A video conferencing system includes a camera and a display within a room. The camera is directed towards participants in a foreground against a background. The room has lighting defining at least foreground luminance. The display defines maximum display luminance, and the display and flare of the room define minimum display luminance. The camera, the display, and/or the room are adapted to provide one or more of the following. First, that the maximum display luminance is greater than the foreground luminance but less than the foreground luminance times a first constant. Second, that the maximum display luminance is greater than the minimum display luminance by more than a second constant. Third, that illumination color of foreground images displayed on the display substantially match illumination color of the foreground. Fourth, that a color of background images displayed on the display substantially matches a color of the background.

Abstract: A method of videoconferencing includes arranging a portable environment to include a first wall generally parallel to and spaced from a second wall and facing a videocamera on the first wall toward the second wall. An on-camera subject zone is implemented between the first wall and the second wall via: (1) setting a field-of-view of the videocamera to include the second wall while excluding a peripheral edge of the second wall; and (2) positioning a subject station between the first wall and the second wall and setting the on-camera subject zone within a boundary defined by the field-of-view of the videocamera extending from the subject station to the second wall.

Abstract: An event management system is configured to detect an overlap between events and provide a communication to remediate the overlap to one or more event attendees.

Abstract: A technique for enhancing the illusion of physical presence in a common space during a multipoint video conference is disclosed. The technique may include controlling the appearance of a first portion of the video images separately from an appearance of a second portion of the video images to achieve a consistent image appearance across the multipoint videoconference.

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.

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: Telepresence system having a media wall with one or more cameras and a participant table located a fixed distance from one or more of the cameras are useful in creating images for video conferencing. A back edge of the table is convex and a center of the back edge is aligned with a central camera. The center of the back edge is located horizontally closer to the central camera than either end of the back edge.

Abstract: Cameras are adjusted by setting magnifications of two or more cameras to be substantially equal, focusing the two or more cameras, and setting the two or more cameras so that portions of an object captured thereby when displayed are aligned.

Abstract: An apparatus has a content node to logically select a first A/V stream from an application layer of a first network and a collaboration node to logically select a second A/V stream from an application layer of a second network. A set of non-network media link interfaces are configured to transmit the second A/V stream from the collaboration node to the content node, and to transmit the first A/V stream from content node to the collaboration node. The non-network media link interfaces provide for limited information encoding to prevent network protocol information from being transferred between the first and second networks.

Abstract: A method including creating a local view for a local endpoint, where the local view is created from a local topology for the local endpoint, where the local topology is created from a central topology, scanning for a request to change the local view for the local endpoint, and updating the local view for the local endpoint when the request to change the local view will not violate the local topology for the local endpoint and will not violate the central topology.

Abstract: A method of creating a synthetic bridge (100) has select data (406) logically extracted from an application layer of a first network (12A) which contains one or more first data streams to be transported to a second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B) which contains one or more second data streams to be transported to the first network (12A). The two or more first and second data streams are transported over separate sets of non-network media link interfaces (130-133) that only allow for limited information encoding and inherently prevent any network protocol information from being passed with the two or more first and second data streams until after the two or more first and second data streams are in the control of the opposite network from which they were transported.

Abstract: An event management system is configured to provide first status information corresponding to a scheduled event to at least a first person associated with an in progress event where the in progress event includes a first plurality of event endpoints that provide a first set of media streams to a first set of attendees. The event management system is also configured to provide second status information corresponding to the in progress event to at least a second person associated with the scheduled event where the scheduled event is scheduled to include a second plurality of event endpoints that provide a second set of media streams to a second set of attendees.

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.
