First Claim
1. A non-transitory computer readable medium for use in a computing system for operating a plurality of computing devices, the computing system comprising one of the computing devices and an image composing unit for generating a common video signal for a display device, wherein said non-transitory computer readable medium carries computer instructions that, when executed by at least one processor or computer, controls the at least one processor or computer for:
- partitioning a display area of the display device into a plurality of display area sections corresponding to source signals of the computing devices by painting the display area sections on a display of the one computing device with key information identifying corresponding source signals, wherein at least one of the display area sections is related to at least one other computing device, wherein the display is output as a first source signal of the source signals, and wherein a composite display area section of the display area sections is painted with key information designating a weighted average of two source signals;
determining key information from the first source signal of the one computing device;
determining a weighted average of the two source signals according to the determined key information;
switching between the source signals of the computing devices and the weighted average based on the determined key information to create the common video signal;
receiving an input signal from at least one input device, wherein the input signal corresponds to a position within the display area, the position being in a display area section corresponding to a target computing device of the computing devices;
providing the input signal to the target computing device;
synchronizing the two source signals; and
when one of the at least one other computing device fails, capturing the source signals of all of the computing devices with;
(i) a frame buffer; and
(ii) an independent clock.

Abstract
A computing system includes a computing device and an image composing unit for generating a common video signal for a display device. The computing device is adapted to partition a display area of the display device into a plurality of sections. One of the sections is related to another computing device. The computing device is further adapted to receive an input signal from an input device. The input signal is relatable to a position within the display area. The computing device is further adapted to provide the other computing device with the input signal depending on the position being in one of the sections related to the other computing device.
