Abstract
A 3D graphics processing system in a preferred embodiment has an input for a digital video data stream. The system has a graphics engine, for processing graphics request code and data, in communication with a host computer over a data bus and also in communication with a frame buffer. It also has an input for a digital video data stream, and the input is in communication with the graphics engine. A control arrangement interrupts processing by the graphics engine of conventional graphics request code and data to permit priority processing of the digital video data stream. In this manner, an image associated with the digital video data stream may be displayed in real time in a desired plane that may be accessed and processed by the graphics processing system as a graphic image. In a further embodiment, the control arrangement is operative to interrupt processing by the graphics engine at a span break and the image associated with the digital video data stream and processed by the graphics engine is stored in the frame buffer.
