    Abstract: An information handling apparatus for transferring and composing image signals including a plurality of media sources configured to provide a corresponding plurality of image signals, a media bus connected to the media sources, and a media control module coupled to the media bus. The media bus allows selective access for the plurality of image signals. The selective access enables composition of the independent image signals in response to control information. The media control module receives a composed image signal from the media bus and to provides the composed image signal to a display device.

    Abstract: An information handling apparatus for transferring and composing image signals for display including a bus interface circuit adapted to allow selective access to a bus of an independent image signal generated by an independent image source. The selective access enables composition of the independent image signal in response to control information; the composition enables real time display of a composed image signal.
