    Abstract: A video encoder may use an adaptive Wiener filter inside the core video encoding loop to improve coding efficiency. In one embodiment, the Wiener filter may be on the input to a motion estimation unit and, in another embodiment, it may be on the output of a motion compensation unit. The taps for the Wiener filter may be determined based on characteristics of at least a region of pixel intensities within a picture. Thus, the filtering may be adaptive in that it varies based on the type of video being processed.

    Abstract: A system, apparatus, method, and article to process a flexible macroblock ordering and arbitrary slice ordering are described. The apparatus may include a video decoder. The video decoder includes a processor to store coding parameters of one or more neighboring macroblocks in a data buffer. The neighboring macroblocks are previously decoded macroblocks and are adjacent to a current macroblock. The processor is to store control parameters for each of the one or more neighboring macroblocks in the data buffer. The processor is to reconstruct coding parameters for the current macroblock using availability information associated with the neighboring macroblocks.

    Abstract: Systems, methods, and computer program products that can be used to determine a search range (SR) when performing motion estimation at, for example, a video encoder or decoder. Determining a motion vector for a current block during motion estimation may involve searching within a search window that may reside in a reference frame, or in a previously decoded block that spatially or temporally neighbors the current block. Such a search seeks a motion vector that minimizes a metric, such as a sum of absolute differences between corresponding blocks of reference frames. A motion vector that minimizes such a metric may be a good candidate for use in motion estimation. The search may become more efficient if a search range is determined such that the extent of the search is bounded. A search range may be determined at the block level or at the picture level.
