Abstract

An on screen display (OSD) method and apparatus is provided for controlling an on screen display generator with a reduced instruction set processor to advantageously sort and link multiple OSD windows for a video display. More particularly, an on screen display (OSD) analyzes a list of OSD window starting points by sorting into the order of starting points by iteratively sorting small groups of starting points, and linking the OSD window data to correspond to the iteratively sorted starting points. Specifically, a list of eight starting points are sorted in groups of four six times (i.e., first four, last four, middle four, first four, last four, and middle four), achieving processing speed advantages.
