Apple Receives Their Eighth iChat Videoconferencing Patent

October 23, 2012 | Telepresence Options
From PatenlyApple,

Apple has been granted their eighth videoconferencing patent since 2009 titled "Video communication systems and methods," which relates to systems and methods for removing a background from a video stream of a videoconference participant environment and for optionally adding substitute background video data into the video stream and providing the video stream to videoconference participants.

In a videoconferencing example, an image of a background is stored. Thereafter, video of the background and the participant is received, and the image of the background is subtracted from the video frames. Substitute background video could be merged into the video frames and the merged video frames could be transmitted to a videoconference.

 Apple credits Senior VP of iPhone Software Scott Forstall, Jean-Pierre Ciudad, Michael Stochosky, Kurt Knight, Ralph Brunner and Chendi Zhang     as the inventors of granted patent 8,294,823 which was originally filed in Q3 2006.
