Abstract
A video moving message system in which images are shifted one pixel width at a time from one video monitor to another. The video monitors are arranged side by side and/or stacked one over the other. Row and column counters are reassigned for a video read only memory matrix so as to enable accessing of image data stored in the read only memory through these reassigned counters. The image data is read out and sent to pixels on the video monitors which correspond to the row and counter addresses in the read only memory matrix. By reassigning during each blanking interval of a video monitor, the image on the video monitor appears to shift by at least one pixel width on the video monitor. The image is scrolled from one video monitor to the next in succession.
