    Abstract: A video decoding device receives an array of transform coefficients for a chroma component of video data. The video decoding device receives entropy encoded data representing the value of a split flag associated with the chroma component. The value of the split flag indicates whether the array of transform coefficients is divided into smaller transform blocks. The video decoding device determines a context for the entropy encoded data representing the split flag. The context is based on the value of a split flag associated with another component of video data. The video decoding device entropy decodes the data representing the value of the split flag based on the determined context using context adaptive binary arithmetic coding (CABAC). The luma and chroma components have independent residual quadtree (RQT) structures.

    Abstract: An apparatus for coding video data using a single-loop decoding approach may include a memory unit and a processor in communication with the memory unit. In an example, the memory unit stores the video data, the video data including a base layer and an enhancement layer. The base layer includes a base layer block, a non-constrained INTRA mode block, and an INTER mode block. The base layer block includes a sub-block located at least partially within one of the non-constrained INTRA mode block or the INTER mode block. The enhancement layer includes an enhancement layer block located at a position in the enhancement layer corresponding to a position of the base layer block in the base layer. The processor approximates pixel values of the sub-block and determines, based at least in part on the approximated pixel values, pixel values of the enhancement layer block.

    Abstract: Techniques coding video data, including a mode for intra prediction of blocks of video data from predictive blocks of video data within the same picture, may include determining a predictive block of video data for the current block of video data, wherein the predictive block of video data is a reconstructed block of video data within the same picture as the current block of video data. A two-dimensional vector, which may be used by a video coder to identify the predictive block of video data, includes a horizontal displacement component and a vertical displacement component relative to the current block of video data. The mode for intra prediction of blocks of video data from predictive blocks of video data within the same picture may be referred to as Intra Block Copy or Intra Motion Compensation.

    Abstract: An apparatus for coding video information may include a memory unit configured to store video information associated with a picture and a processor in communication with the memory unit configured to resample video information of a reference picture to obtain a resampled picture having a plurality of slices and a different picture size than a picture to be encoded. Further, the processor may determine slice definitions for slices in the resampled picture. The slices of the resampled picture may correspond to slices of the reference picture. The processor may determine, based on the slice definitions, whether a slice of the resampled picture satisfies one or more slice definition rules. In response to determining that the slice of the resampled picture does not satisfy at least one slice definition rule, the processor can modify the slice definition for the slice so as to satisfy the slice definition rule.
