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.

Video distribution hub

A video interface system which samples an input video signal to capture a subset of pixels from first and second frames of the signal. A frame buffer temporarily stores the captured subsets of pixels from the first and second frames and a display interface unit reads the stored pixels out of the frame buffer for transfer to a flat panel display. The subsets of pixels from the first and second frames are interleaved on the display to provide a video image. The display is updated by replacing one of the displayed subsets of pixels with a subset of pixels captured from a subsequent frame of the video signal. In one embodiment, the subset of captured pixels from the first frame includes those pixels for which the sum of the respective row and column numbers is either odd or even and the subset of captured pixels from the second frame includes those pixels for which the sum of the respective row and column numbers is even or odd.
