DESCRIBED IS A TV SYSTEM THAT USES A SINGLE PIXMAN (190) ACROSS MULTIPLE VIDEO RASTERS HAVING DIFFERENT RASTER SIZES. IN GENERAL, THE TV SYSTEM USES AT LEAST TWO HEADERS TO SELECT DIFFERENT PORTIONS OF A SINGLE PIXMAP (190) TO BE DISPLAYED BASED ON DIFFERENT RASTER SIZES. SPECIFICALLY, EACH OF THE TWO HEADERS POINTS TO A SINGLE PIXMAP (190). IN THE TV SYSTEM, THE SIZE OF THE CENTRAL PORTION IS FIXED WHILE THE SIZE OF THE SIDEPANEL PORTION CAN BE ADJUSTED DIPENDING ON THE DISPLAYING MODE.IN RESPONSE TO DIFFERENT DISPLAYING MODES, THE TV SYSTEM SELECTIVELY INVOKES ONE OF THE TWO HEADERS TO SELECT A RESPECTIVE PORTION TO BE DISPLAYED IN THE PIXMAP (190). BY DOING SO, ASINGLE PIXMAP (190) CAN BE USED ACROSS MULTIPLE VIDEO RASTERS HAVING DIFFERENT RASTER SIZES.(FIG.6) |
