Abstract
The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. In addition, full-motion video may also be displayed in a window defined in the frame buffer. If the native resolution of the full-motion video is larger than the window defined in said frame buffer then valuable memory space and memory bandwidth is being wasted by writing said larger full-motion video in a memory system (and later reading it back) when some data from the full-motion video will be discarded. Thus, a video pre-processor is disclosed to reduce the size of the full-motion video before that full-motion video is written into a memory system. The video pre-processor will scale the full-motion video down to a size no larger than the window defined in the frame buffer.
