PURPOSE: An MPEG(Moving Picture Experts Group)-based 3D graphic accelerator is provided to accelerate efficiently 3D graphic data on an MPEG-based HDTV(High Definition TeleVision) or a DTV(Digital TeleVision) by mounting a 3D graphic accelerator in a video decoder. CONSTITUTION: A 3D graphic accelerator(200) outputs 3D graphic data by processing inputted 3D primitives geometrically or rendering the inputted 3D primitives. A video decoder(100) outputs decoded video data by decoding inputted video bit streams. A multiplexer(109) outputs the 3D graphic data and the decoded video data. A frame memory(20) divides the 3D graphic data and the decoded video data into current images and previous images and stores the divided current images and the divided previous images. A display processing portion(110) performs a signal processing operation for the images stored in the frame memory(20).
