    摘要: A method and apparatus for processing a video block extracted from an encoded bitstream. The method generally includes the steps of (A) generating a normal block by inverse transforming the video block, the normal block having a normal resolution, (B) generating an alternate block from the video block, the alternate block comprising image detail (i) present after the inverse transforming and (ii) absent from the normal block and (C) generating an output block based on the normal block and the alternate block, the output block having an output resolution greater than the normal resolution.

    摘要: The present invention is directed to an improved method for the binarization of data in an MPEG data stream. The invention makes use of unary binarization to create codewords up until an index threshold. Once the threshold has been met, succeeding code symbols have appended to them an exp-Golomb suffix. This hybrid binarization scheme reduces the number of binary codewords to be processed by a Binary Arithmetic Coder (BAC), thus reducing the computation required by the BAC.

    摘要: The present invention extends the generalized Lloyd algorithm (GLA) for vector quantizer (VQ) codebook improvement and codebook design to a new linearly-constrained generalized Lloyd algorithm (LCGLA). The LCGLA improves the quality of VQ codebooks, by forming the codebooks from linear combinations of a reduced set of base codevectors. The present invention enables a principled approach for compressing texture images in formats compatible with various industry standards. New, more flexible compressed texture image formats are also made possible with the present invention. The present invention enhances signal compression by improving traditional VQ approaches through the integrated application of linear constraints on the multiple pattern and signal prototypes that represent a single pattern or block of signal samples.

    摘要: In one embodiment of the invention, decompressed video signals are upscaled and then filtered using a combined mosquito noise reduction (MNR) and aliasing coring filter that reduces both mosquito noise in the decompressed video signals as well as aliasing noise resulting from the upscaling process. In one implementation, the combined coring filter includes a dual-band filter having two passbands interleaved with two stopbands. The strength of the coring filter may be dynamically controlled based on compression information (e.g., quantizer scales indicative of video quality) associated with the compressed video bitstream from which the decompressed video is recovered.

    摘要: The present invention is a low complexity method for reducing the number of motion vectors required for bi-predictive frames or fields in digital video streams. The present invention utilizes the motion vectors located in the corner blocks of a co-located macroblock, rather than all motion vectors, when determining the motion vectors of a current block. This results in reduced resources in the computation of direct motion vectors for a bi-predictive frame or field.
