摘要： Techniques and systems are provided for coding video data. For example, a method of coding video data includes determining one or more illumination compensation parameters for a current block and coding the current block as part of an encoded bitstream using the one or more illumination compensation parameters. In some cases, the method can include determining one or more spatially neighboring samples for the current block and deriving the one or more illumination compensation parameters for the current block based on at least one of the one or more spatially neighboring samples. The method can further include signaling, individually, for the current block, an illumination compensation status in the encoded bitstream. The method can further include signaling at least one of the one or more illumination compensation parameters for the current block in the encoded bitstream.

摘要： In an example, a method of decoding video data may include receiving a first block of video data. The first block of video data may be a sub-block of a prediction unit. The method may include receiving one or more blocks of video data that neighbor the first block of video data. The method may include determining motion information of at least one of the one or more blocks of video data that neighbor the first block of video data. The method may include decoding, using overlapped block motion compensation, the first block of video data based at least in part on the motion information of the at least one of the one or more blocks that neighbor the first block of video data.

摘要： In an example, a method of processing video data includes determining a candidate motion vector for deriving motion information of a current block of video data, where the motion information indicates motion of the current block relative to reference video data. The method also includes determining a derived motion vector for the current block based on the determined candidate motion vector, where determining the derived motion vector comprises performing a motion search for a first set of reference data that corresponds to a second set of reference data outside of the current block.

摘要： Techniques are described for sub-prediction unit (PU) based motion prediction for video coding in HEVC and 3D-HEVC. In one example, the techniques include an advanced temporal motion vector prediction (TMVP) mode to predict sub-PUs of a PU in single layer coding for which motion vector refinement may be allowed. The advanced TMVP mode includes determining motion vectors for the PU in at least two stages to derive motion information for the PU that includes different motion vectors and reference indices for each of the sub-PUs of the PU. In another example, the techniques include storing separate motion information derived for each sub-PU of a current PU predicted using a sub-PU backward view synthesis prediction (BVSP) mode even after motion compensation is performed. The additional motion information stored for the current PU may be used to predict subsequent PUs for which the current PU is a neighboring block.

The method also includes deriving, separately for each respective sub-block of the plurality of sub-blocks, motion information comprising performing a motion search for a first set of reference data that corresponds to a second set of reference data outside of each respective sub-block. The method also includes decoding the plurality of sub-blocks based on the derived motion information and without decoding syntax elements representative of the motion information.
