Abstract
A memory efficient method for translating and displaying sub-picture images for DVD data. The method uses less memory than prior systems. Rather than storing the sub-picture image in a memory, the method decodes and displays the sub-picture images on-the-fly. Subsequent sub-picture pixels are being translated as a given sub-picture pixel is being displayed on a display.
