SYSTEM AND METHOD FOR ON-THE-FLY KEY COLOR GENERATION |
摘要 |
The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. In addition, a full-motion video may also be displayed. Reading from both the frame buffer and the full-motion video buffer when displaying the full-motion video window wastes valuable memory bandwidth. Thus, the disclosed system provides a system and methods for identifying where the video output system must read from the frame buffer and where it must read from the full-motion video buffer while minimizing the amount of area it reads from both the frame buffer and the full-motion video buffer.
