Abstract
An advanced decoder provides enhancement processing in accordance with information previously known only to the decoder and/or encoder. Preferably, advanced digital video image enhancement utilizing bitstream information is provided in an integrated manner with advanced decoding and, more preferably, provides for MPEG decoding and image enhancement. In addition to advanced edge detection and other advanced processing tools, the invention further enables the use of decoder based coding-type operations, such as reverse superresolution, as well as advanced superresolution, and 3-D display processing techniques in conjunction with video processing. The invention is therefore capable of reducing system complexity and/or bandwidth, requirements, and improving system robustness and/or the ultimate quality of the enhanced video signal, among other advantages.
