Abstract
A method for visually multiplexing video information presentation system permits obscured windows to be continuously updated, which, when revealed, will present the new contents within the window without requiring a host system to redraw all obscured window areas. The system operates by holding the contents of each windows pixels in separate areas of memory. The displayed screen is a mosaic of pixels chosen based on a pixel position ownership table that is maintained by the system as screen commands are sent by the host.
