    Abstract: The format of telecined video may be determined including a bottom field first cadence. In addition, video using 2:3:3:2 top field first can be identified. Moreover, mixed cadence videos can also be detected. In some embodiments, mixed cadence videos may be detected by calculating variances of different areas within a frame.

    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.
