Abstract
Video adapter hardware and software permitting the display of computer information and television signals across several display devices. The video adapter hardware includes two graphics user interface accelerators, two television tuners, one or more video decoders, and one or more video multiplexers. Each accelerator is coupled to a memory unit for access to graphics data. One television tuner accepts input from an outside television source, such as a cable television company or a video cassette recorder. In addition, the video multiplexers accept input from other external video sources. Video data is output from the graphics accelerators to multiple screens. Video adapter software displays a tool window allowing the user to select first input for the first display device and a second input for the second display device. The software displays the results of the two inputs on the respective display devices. If the inputs are identical, however, the information may be displayed across both display devices.
