摘要： A video coding device includes a memory configured to store video data, and processing circuitry in communication with the memory. The processing circuitry is configured to determine that a current block of the video data stored to the memory is to be coded according to a merge mode, and to determine a temporal candidate associated with a merge candidate list for the current block in accordance with the merge mode. The processing circuitry is further configured to determine a pool of spatial candidates associated with the merge candidate list, based on each spatial candidate of the pool having a same reference picture as the temporal candidate, and to set a local illumination compensation (LIC) flag value for the temporal candidate based on respective LIC flag values of one or more spatial candidates of the pool.

摘要： During a coding process, systems, methods, and apparatus may code data representative of the positions of elements of a chain that partitions a prediction unit of video data. Some examples may include generating the data representative of the positions of elements of a chain that partitions a prediction unit of video data. Each of the positions of the elements except for a last element may be within the prediction unit. The position of the last element may be outside the prediction unit. This can indicate that the penultimate element is the last element of the chain. Some examples may code the partitions of the prediction unit based on the chain.

摘要： The techniques of this disclosure apply to loop filtering across slice or tile boundaries in a video coding process. In one example, a method for performing loop filtering in a video coding process includes determining that pixels corresponding to filter coefficients of a filter mask for a loop filter are across a slice or tile boundary, removing filter coefficients corresponding to the pixels across the slice or tile boundary from the filter mask, renormalizing the filter mask without the removed filter coefficients, performing loop filtering using the renormalized filter mask

摘要： This disclosure proposes techniques for transform partitioning in an intra-prediction video coding process. In one example, for a given intra-predicted block, a reduced number of transform unit partition options is allowed, based on certain conditions. In another example, transform units are decoupled from prediction units for intra-predicted block. For a given prediction unit, transforms of different sizes and shapes from the prediction unit may be applied. In another example, a reduced number of intra-prediction modes are allowed for a prediction unit having a non-square shape.

摘要： A video coding device may be configured to code a bitstream including multiple views plus depth information. Two of the views may have reduced resolutions, while a third view may have a full resolution. The third view may be predicted relative to upsampled versions of the two reduced-resolution views. Each view may include texture data and depth data, such that a view component may include a texture component and a depth component. Moreover, the texture and depth components may be arranged within an access unit according to a particular order, which may simplify component extraction from the access unit.

摘要： A unified candidate block set for both adaptive motion vector prediction (AMVP) mode and merge mode for use in inter-prediction is proposed. In general, the same candidate block set is used regardless of which motion vector prediction mode (e.g., merge mode or AMVP mode) is used. In other examples of this disclosure, one candidate block in a set of candidate blocks is designated as an additional candidate block. The additional candidate block is used if one of the other candidate blocks is unavailable. Also, the disclosure proposes a checking pattern where the left candidate block is checked before the below left candidate block. Also, the above candidate block is checked before the right above candidate block.

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.
