摘要： This disclosure describes techniques for coding video data. In particular, this disclosure describes techniques for loop filtering for video coding. The techniques of this disclosure may apply to loop filtering and/or partial loop filtering across block boundaries in scalable video coding processes. Loop filtering may include, for example, one or more of adaptive loop filtering (ALF), sample adaptive offset (SAO) filtering, and deblocking filtering.

摘要： In one embodiment, an apparatus configured to code video data includes a processor and a memory unit. The memory unit stores video data associated with a first layer having a first spatial resolution and a second layer having a second spatial resolution. The video data associated with the first layer includes at least a first layer block and first layer prediction mode information associated with the first layer block, and the first layer block includes a plurality of sub-blocks where each sub-block is associated with respective prediction mode data of the first layer prediction mode information. The processor derives the predication mode data associated with one of the plurality of sub-blocks based at least on a selection rule, upsamples the derived prediction mode data and the first layer block, and associates the upsampled prediction mode data with each upsampled sub-block of the upsampled first layer block.

摘要： A video decoder determines, based at least in part on a size of a prediction unit (PU), whether to round either or both a horizontal or a vertical component of a motion vector of the PU from sub-pixel accuracy to integer-pixel accuracy. The video decoder generates, based at least in part on the motion vector, a predictive sample block for the PU and generates, based in part on the predictive sample block for the PU, a reconstructed sample block.

摘要： A video encoder performs multiple coding passes on coefficients in a coefficient block. During each coding pass, the video encoder encodes a different set of syntax elements for coefficients in the coefficient block. A video decoder uses the syntax elements for a coefficient to determine the value of the coefficient. When the video encoder performs a coding pass, the video encoder selects a coding context for a syntax element based at least in part on a syntax element generated in an earlier coding pass for a non-causal coefficient and based at least in part on a value of a syntax element generated during the current coding pass for a causal coefficient. The video encoder entropy encodes the syntax element based on the selected coding context. A video decoder performs a similar series of coding passes in which the video decoder selects coding contexts and entropy decodes the syntax elements.

摘要： In one example, a device for coding video data includes a video coder configured to determine whether a transform coefficient of a video block is a DC transform coefficient, when the transform coefficient is determined to be the DC transform coefficient of the video block, determine a context for coding the transform coefficient based on the transform coefficient being the DC transform coefficient without regard for a size of the video block, and entropy code the transform coefficient using the determined context.

摘要： This disclosure relates to methods and apparatus for encoding and decoding video data. In an example an intra-mode for predicting a current block of video data and most probable intra-modes (MPMs) for predicting the current block of video data may be determined. MPMs for predicting the current block of video data may be determined. An index for each of the MPMs based on an order in which the intra-mode for predicting the current block is compared to the MPMs may be determined. When one of the MPMs for predicting the current block matches the intra-mode for predicting the current block, the index of the matching MPM.
