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 relates to techniques for reducing the amount of additional data encoded with a block encoded using intra-predictive coding. Particularly, the techniques provide apparatus and methods of applying a smoothing filter to prediction samples used in intra-predictive coding. For example, in fixed mode-dependent intra-predictive coding, a video encoder may determine the type of smoothing filter applied to prediction samples based on block size and intra-prediction mode combination associated with the current block, where the combination is used to look up a filter in a first filter table. In adaptive mode-dependent intra-predictive coding, the encoder uses two filters, one from the first filter table and another from a second filter table, applies both filters, and determines which yields better results. When the second filter table filter yields better results, the encoder encodes a filtering indication. When a filter from the first filter table is used, no filtering indication is encoded.

摘要： In one example, a method for coding video data includes identifying a scan path for scanning significance information associated with a quantized transform coefficient. The method also includes determining a context support neighborhood for entropy coding the significance information associated with the quantized transform coefficient, wherein the context support neighborhood excludes one or more context support elements that are located in the scan path.

摘要： A video encoder divides a picture into a plurality of picture partitions, such as tiles or wavefront parallel processing (WPP) waves. The picture partitions are associated with non-overlapping subsets of the treeblocks of the picture. The video encoder generates a coded slice network abstraction layer (NAL) unit that includes encoded representations of the treeblocks associated with a slice of the picture. The coded treeblocks are grouped within the coded slice NAL unit into segments associated with different ones of the picture partitions. The video encoder pads one or more of the segments such that each of the segments begins on a byte boundary.
