Abstract
A system and method to decode encoded video images in such a manner as to maintain high quality images while reducing the computation time needed to decode the images. The system takes into account that the resultant display generated may only have a fraction (1/16) of the resolution of the original image. Thus, optimizations are realized by modifying the inverse discrete cosine transform (IDCT) and inverse weighting (IW) processes to process only the portion of the image to be displayed.
