摘要： For encoding, each video frame is segmented into slices; each slice, into macroblocks; and each macroblock, into blocks. Encoded macroblock and block signals are generated corresponding to macroblock and block information of each slice, respectively. An encoded bitstream is generated in accordance with the encoded macroblock and block signals, wherein all of the macroblock signals for each slice precede all of the block signals for each slice. For decoding, an encoded bitstream is received, wherein (1) a portion of the encoded bitstream corresponding to each video frame corresponds to slices; and (2) a portion of the encoded bitstream corresponding to each slice comprises encoded macroblock signals followed by block signals for the entire slice. The macroblock and block signals of each slice are decoded and decoded video signals are generated in accordance with the decoded macroblock and block signals.

摘要： A method, apparatus, and system for generating an image from subsampled, three-component image data. First and second components of the image data are processed to generate a dither index to a dither lookup table. The third component of the image data is dithered. CLUT index data is then generated using the dither data from the dither lookup table and the dithered third-component data. The CLUT index data may then be used to generate the image. In a preferred embodiment, a 14-bit dither index to a 16K dither lookup table is generated from the U and V components of a (4.times.4) block of YUV9 data. The Y components are dithered and then processed with the appropriate dither lookup table data to generate 16 CLUT index values for the (4.times.4) block. The dithering and processing is preferably performed on a row-by-row basis in a pseudo-SIMD fashion.

摘要： A method and apparatus for hardware-base edge handling in video post-processing. In one embodiment, the method includes the identification of at least one unstored input pixel required to compute an output pixel during output pixel computation. Once identified, a pixel value is generated for the at least one unstored input pixel according to a detected edge handling mode. The generation of the pixel value for the unstored input pixel is performed, in one embodiment, if a position of the unstored input pixel is outside a pixel frame boundary. For example, in one embodiment, for output pixel computation of a scaling operation, the frame boundaries include a left (top) edge and a right (bottom) edge for which input pixels required to compute output pixels at or near the frame boundaries do not exist. Other embodiments are described and claimed.

摘要： A method and apparatus for hardware-based anamorphic video scaling. In one embodiment, the method includes the fetch of zero or more new input pixels according to an entry of an input control memory corresponding to a current output pixel. Once fetched, the zero or more new input pixels replace at least one stored input pixel of N, input pixels. Using the updated N, input pixels and an N, coefficient set selected according to an entry of a coefficient memory corresponding to the current output pixel, a pixel computation, such as, for example, an anamorphic scaling computation, is performed. In one embodiment, the anamorphic scaling is performed by subdividing an X×Y pixel frame into X/M M×Y pixel subframes. Other embodiments are described and claimed.
