Abstract
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.
