A method is provided in one example embodiment and includes receiving a first presentation material for a videoconference, wherein the first presentation material is to be displayed in a display area associated with the videoconference; determining a first complexity of the first presentation material; and displaying the first presentation material on a first display based on the determined first complexity. In more particular embodiments, the method can include determining a location of a participant that will view the first presentation material; and displaying the presentation material on a second display based on the location of the participant. The location of the participant can be determined using audio data or video data.

System and method for scaling a video presentation based on presentation complexity and room participants

Particular embodiments generally relate to video compression. In one embodiment, a store of reference frames is provided in memory. The reference frames may be classified based on a plurality of classifiers. The classifiers may correspond to features that are found in the reference frame. A frame to encode is then received. The frame is analyzed to determine features found in the frame. As macroblocks in the frame are encoded, a macroblock is analyzed to determine which feature may be included in the macroblock. The feature is used to determine a classifier, which is used to determine a subset of the reference frames. The subset is then searched to determine a reference frame for the macroblock.

Video compression using search techniques of long-term reference memory

A system and method for reducing blurred video caused by intra-coded IDR-frames sent in response to when a destination endpoint in a multipoint videoconference switches to a new video source. An embodiment according to the invention comprises using inter-coded temporal predictive referencing a long term reference frame (LTRF) instead of IDR-frames in a multipoint videoconference system.

Video switching without instantaneous decoder refresh-frames

A method is provided in one example embodiment and includes establishing a video session in which a plurality of displays are used for rendering video data, and evaluating a presentation element in order to identify a control element that includes control data. The control element is included in the presentation element. The method further includes communicating at least a portion of the control data such that it can be used to determine which video data is to be rendered on the plurality of displays.

System and method for controlling video data to be rendered in a video conference environment

Techniques are provided for managing long-term reference frames (LTRFs) for two or more video sources. A first video source is selected from a plurality of video sources. The first video source is encoded to produce an encoded video stream, where a reference frame message identifies a recent video frame as long-term reference frame (LTRF) associated with the first video stream. The process is repeated for other video streams. The LTRF associated with the first video stream is used as a reference for temporal predictive coding upon receiving a signal that the first video source has been re-selected.

Camera coupled reference frame

A system and method for creating a virtual round table videoconference is described. An embodiment of the system comprises a plurality of displays arranged in an arc configuration with a table to create a virtual round table. Cameras are arranged around the plurality of displays such that when a participant looks at a display with an image of a remote participant, the camera associated with the display captures an image of the participant's gaze, making eye contact with the camera. The image is displayed at the remote participant's endpoint creating the effect of eye contact between the participants. In another embodiment, audio speakers are arranged to provide directional sound such that the video source for a display and the audio source for the associated speaker are from the same endpoint.
