TW589615B - On screen display window splitting method - Google Patents

Abstract

A method for splitting an OSD (on screen display) is disclosed. The splitting of the OSD can be done within a window residing on a full screen display, or the splitting can be done using the entire surface of the display to hold the split OSD areas. This is accomplished by creating four additional parameters and storing them in memory. The four parameters are horizontal and vertical split points and the horizontal and vertical distances between the split OSD areas. As many split areas can be created as the size of the areas, the distance between areas and the size of the screen will allow. The gaps between areas show the underlying original display data unaffected by the OSD data. Each split OSD area can provide different information and have different display characteristics all under the control of a microprocessor.
