Abstract: An integrated computer, scanner, and printer has elements of all three in a single enclosure with a single CPU performing all of the control tasks for the three, usually separate, devices. The three functions also share memory space, and control circuitry for the scanning and printing operations are interfaced directly to the system bus of the computer. Control routines in a preferred embodiment are integrated into a single system BIOS. In embodiments of the invention, a light source, such as a laser source, used for electrostatically writing images on a drum for printing, is diverted and also used for scanning operations. In another alternative embodiment, a device-driver-software transparent extended enhanced parallel port is provided for expansion of the bus into an external copy of the internal bus, such that expansion ports may be transparently provided in an external docking box.

Abstract: A video jukebox service has a world-wide array of file servers interconnected by data links and having video input apparatus. Each file server has a plurality of connected clients. Video clippings input at the video input apparatus are shared with the other file servers and stored in a database at each file server. Clients are notified of availability of video clippings, and clippings are downloaded to client stations on demand. In a preferred embodiment, the file server network is a toriodal arrangement, and client communication nodes equal in number to the number of file servers are interconnected in a toroidal fashion as well. Individual client stations are connected to individual ones of the client communication nodes, with the overall network in the form of nested toroids.
