ABSTRACT:
An improved processing system (10) for video signal processing. The system uses only one newer version scan-line video processor (12) at nearly maximum efficiency, with a digital input that is at a common rate. The processor performs motion detection, motion adaptive scan conversion, horizontal and vertical scaling and applies sharpness control within a limited amount of instruction space, and applies these functions to four different video formats.
