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.

Abstract: In a printed circuit board having a plural number of conductor layers separated by a plural number of insulator layers, a Faraday cage is constructed including a first and a second ground plane disposed in a first and second conductor layer respectively. The ground planes being electrically interconnected at their peripheries, preferably by a plurality of vias. A third conductor layer is disposed between the first and second conductor layers in which a plurality of signal paths are defined. The Faraday cage surrounds a shielded portion of the third conductor layer so that electrical signals conducted through the shielded portion are isolated from electrical noise. The invention finds particular application in a mixed digital/analog board separated into a digital section of the board having a digital ground plane defined in one of the conductor layers and a plurality of digital signal paths defined in another of the conductor layers and an analog section of the board having the Faraday cage and the shielded portion. Thus, the plurality of signal paths in the shielded region are intended for analog signals which are sensitive to digital noise. Additional conductor layers in the analog section can be added inside and outside the Faraday cage. Those analog signal paths located outside the cage are defined for analog signals which are less sensitive than analog signals in the shielded region. The board may be an audio card for a digital computer.

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

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.
