Abstract

A method, apparatus, and signal-bearing medium for sending to a display device modified regions of a frame buffer. A frame buffer is divided into the regions, and data in the frame buffer represents pixels on the display device. The frame buffer accumulates writes until the region being written to changes, at which time the region is copied to the display device.
