A video graphics system wherein a large quantity of video data is independently and selectively made available to plural video display devices. The large quantity of video data can be contributed to by plural sources of video data of differing formats. Further, the display devices can also be of varying types, each requiring a different input data format. A multi-sourced video distribution element, also referred to as a hub, serves as an interface between one or more sources of video display data and one or more video display devices. One source of data can be identified as a base image, and other sources of data can be utilized for overlay images integrated into the base image. The base image and any integrated overlay images are provided on a pixel bus internal to the hub. The hub can then be configured as an interface to one or more types of video display devices and/or to another hub. A desired portion of the base image and/or an integrated overlay image(s), if any, is then provided for display on the video display device(s) and/or to the interconnected hub.

Multi-sourced video distribution hub

A video distribution hub and display method are disclosed which is capable of driving a plurality of video display monitors as a virtual monitor or monitors. The video distribution hub receives a video signal from a single head graphics card or a suitable video source which signal embodies data within a video buffer on the graphics card or at the video source. The hub processes the received video signal and stores selected data segments corresponding to selected portions of the video buffer in a plurality of frame buffers within the distribution hub. The data stored within the plurality of frame buffers is employed to drive respective video displays, such as flat panel displays or conventional CRT displays. The hub accommodates displays of different resolution. Additionally, the hub accommodates displays having either a portrait or landscape orientation.
