Abstract: Method and related systems for dynamically sharing desktop contents during a video communications call is disclosed. The available communications bandwidth for transmitting desktop content and video content from a host computer to a client computer is divided between the desktop and video contents based on priority levels assigned to each of the desktop and video contents. The display area of the client computer may also be adjusted based on the priority levels.

Abstract: Methods and related systems for encoding video streams are described. Reference and target frames of a video stream are scaled to reduce their resolution. A sliding window is used to compare the reduced resolution reference and target frames and identify blocks, outlined by a sliding window, that include similar content. A motion vector indicating the motion of the identified similar content is determined. Once the motion vector is determined, the reference and target frames are restored to their native resolution and a translated location for the motion vector is identified in the restored frames. The translated location of the motion vector may be used in encoding the frames of the video stream.
