Abstract
A system and method for receiving video from multiple sources, compositing those sources and then republishing the composited video as a source to a virtual camera driver endpoint. In one embodiment, the present method comprises displaying multiple media streams, represented by worksurface image on a shared display. The shared display worksurface image is then re-encoded, and the re-encoded composite image is transmitted to a client computer, where the re-encoded image is transcoded to simulate a device connected to the client computer. The transcoded media stream is then transmitted to a teleconferencing system.
