摘要： In an example, an apparatus for decoding video data includes a video decoder that is configured to determine a number of transform coefficients associated with a block of video data, and to determine whether the number of transform coefficients exceeds a predetermined threshold. The video decoder is also configured to identify a scan order when the number of transform coefficients exceeds the predetermined threshold, wherein the scan order indicates an order in which the transform coefficients have been serialized from a two-dimensional array to a one-dimensional array, and to apply the scan order to inverse scan the number of transform coefficients associated with a block of video data.

摘要： Video coding devices and methods use a function-based definition of scan order to scan transform coefficients associated with a block of residual video data. A video coder may define a scan order for coefficients based on a predefined function and one or more parameter values. A video encoder may use a function-based scan order to scan a two-dimensional array of coefficients to produce a one-dimensional array of coefficients for use in producing encoded video data. The video encoder may signal the parameters to a video decoder, or the video decoder may infer one or more of the parameters. The video decoder may use the function-based scan order to scan a one-dimensional array of coefficients to reproduce the two-dimensional array of coefficients for use in producing decoded video data. In each case, the scan order may vary according to the parameter values, which may include block size, orientation, and/or orientation strength.

摘要： This disclosure describes techniques for coding a video block based on an unclipped version of a motion vector predictor candidate. The techniques include determining a motion vector predictor candidate list including motion vector predictor candidates from neighboring video blocks without clipping the motion vector predictor candidates. More specifically, if one of the motion vector predictor candidates points to a prediction block located outside of a reference picture boundary relative to the current video block, the techniques allow an unclipped version of the motion vector predictor candidate to be included in the candidate list. The current video block is then coded based on a determined unclipped motion vector predictor candidate of the candidate list. Elimination of the motion vector predictor candidate clipping process reduces complexity at both the video encoder and the video decoder.

摘要： A video coder performs a padding operation that processes a set of border pixels according to an order. The order starts at a bottom-left border pixel and proceeds through the border pixels sequentially to a top-right border pixel. When the padding operation processes an unavailable border pixel, the padding operation predicts a value of the unavailable border pixel based on a value of a border pixel previously processed by the padding operation. The video coder may generate an intra-predicted video block based on the border pixels.
