Abstract
In a digital video processing system for processing full-motion video in computer terminal systems, two main rendering paths are created for a computer terminal system: a screen buffer path and a full-motion video path. The screen buffer path renders a desktop display from a screen buffer within the terminal system. The full-motion video path decodes a video stream and then processes the decoded video stream with a video processing pipeline to fit the video frames within a destination video window within the desktop display. The video processing pipeline performs clipping, blending, chroma resampling, resizing, and color converting of the video frames in pipelined stages with minimal memory accesses. A video adapter then combines the desktop display with the processed digital video for a final terminal display.
