Abstract
This is a system and method of processing multiple video streams for a computing device. The system may comprise: a central processing device; a communications bus connected to the central processing device; an input device connected to the central processing device by the communications bus; an output device connected to the central processing device by the communications bus; a multiple video stream processor connected to the output device by the communications bus; and at least two video streams connected to the multiple video stream processor. In addition, the video streams may include input from a CD-ROM, PCMCIA cards, storage devices, peripherals on docking stations and other communications devices. Moreover, multiple video processing device may include input from zoom video ports, buffers and digital-to-analog converters, and a reformatting device. Other devices and systems are also disclosed.
