    摘要: A video block syntax element indicates whether all of the partitions of a video block are predicted based on a same reference list and no greater than quarter-pixel accuracy is used. If the video block syntax element is set, partition-level signaling of the reference lists is avoided. If the video block syntax element is not set, partition-level signaling of the reference lists occurs. If the video block syntax element is set, partition-level syntax elements may be used for each of the partitions of the video block, wherein the partition-level syntax elements each identify one of the reference lists and motion vector accuracy for a given one of the partitions.

    摘要: During the prediction stage of a video encoding and/or decoding process, a video coder can use relatively longer filters for certain motion vectors pointing to certain sub-pixel positions and relatively shorter filters for motion vectors pointing to other sub-pixel positions, where a longer filter generally refers to an interpolation filter with a greater number of filter coefficients, also called taps, while a shorter filter generally refers to an interpolation filter with fewer taps.

    摘要: Systems and methods of filtering video data using a plurality of filters are disclosed. In an embodiment, a method includes receiving and decoding a plurality of filters embedded in a video data bitstream at a video decoder. The method includes selecting, based on information included in the video data bitstream, a particular filter of the plurality of filters. The method further includes applying the particular filter to at least a portion of decoded video data of the video data bitstream to produce filtered decoded video data.
