Abstract
A teleconferencing system in which the video image of a subject in front of a selected background scene is extracted from that scene and transmitted to other locations where selected backgrounds are stored. By compositing the subject and background images at each remote location, both image elements, being originals, will show no loss of detail when projected. For a front projection screen, the projector is inhibited from illuminating a presenter.
