Enhanced single frame buffer display system

摘要

An enhanced single frame buffer video display system is described for combining both video and graphical images. A single frame buffer is implemented which stores a single data format for pixel types which may be interpreted by a conventional video generator for output to conventional color graphics computer display devices. The system utilizes an enhanced graphics controller which does all pixel processing for translating all incoming graphics and video data to a single format type as well as performing, blending and scaling. The system is readily scalable for handling additional format data types.
