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： Combined Intra prediction is disclosed. The combined Intra prediction is generated for encoding or decoding of a current chroma block by combining first Intra prediction generated according to the first chroma Intra prediction mode and second Intra prediction generated according to the second chroma Intra prediction mode. The second chroma Intra prediction mode belongs to an Intra prediction mode group excluding any LM mode. Multi-phase Intra prediction for a chroma component of non-444 colour video data is also disclosed. A mode group including at least two LM modes are used for multi-phase Intra prediction, where mapping between chroma samples and corresponding luma samples is different for two LM modes from the mode group. Furthermore, chroma Intra prediction with one or more LM modes using extended neighbouring area to derive LM mode parameters is also disclosed.

摘要： A method and apparatus for encoding or decoding a motion vector (MV) of a current block of a current picture using advanced temporal motion vector prediction are disclosed. At least two collocated pictures are selected from a set of reference pictures of the current picture. One or more TMVPs are derived based on reference motion vectors (MVs) associated with collocated reference blocks of the collocated pictures. A motion vector prediction candidate set including one or more TMVPs is then determined. The current block is encoded or decoding using the motion vector prediction candidate set. The reference motion vectors (MVs) are scaled before the reference motion vectors (MVs) are used to derive the TMVPs.

摘要： A method of video coding using separate coding trees for luma component and chroma component is disclosed. The luma component and the chroma component are allowed to have its own coding trees to partition the corresponding video data. In one embodiment, a first syntax element is used for each first node of the luma coding tree to indicate whether the first node is split and a separate second syntax element is used for each second node of the chroma coding tree to indicate whether the second node is split. For each CTU, the luma coding tree and the chroma coding tree are signaled using separate syntax elements. Furthermore, for each CTU, the syntax elements for the luma coding tree can be signaled before the syntax elements for each chroma CTU.

摘要： This contribution presents a method on DMM mode coding in 3D-HEVC. In the current 3D-HEVC, the table index in DMM1 is binarizied as a fixed-length code, and it is possible that the signaled index exceeds the valid range of the wedge pattern table. It is proposed to guarantee that any signaled index will be handled correctly by the decoder.
