摘要： A video coding device may encode a video signal using intra-block copy prediction. A first picture prediction unit of a first picture may be identified. A second picture may be coded and identified. The second picture may be temporally related to the first picture, and the second picture may include second picture prediction units. A second picture prediction unit that is collocated with the first picture prediction unit may be identified. Prediction information for the first picture prediction unit may be generated. The prediction information may be based on a block vector of the second picture prediction unit that is collocated with the first picture prediction unit.

摘要： Embodiments disclosed herein operate to improve prior video coding techniques by incorporating an IntraBC flag explicitly at the prediction unit level in merge mode. This flag allows separate selection of block vector (BV) candidates and motion vector (MV) candidates. Specifically, explicit signaling of an IntraBC flag provides information on whether a specific prediction unit will use a BV or an MV. If the IntraBC flag is set, the candidate list is constructed using only spatial and temporal neighboring BVs. If the IntraBC flag is not set, the candidate list is constructed using only spatial and temporal neighboring MVs. An index is then coded which points into the list of candidate BVs or MVs. Further embodiments disclosed herein describe the use of BV-MV bi-prediction in a unified IntraBC and inter framework.

摘要： A video coding device may identify a network abstraction layer (NAL) unit. The video coding device may determine whether the NAL unit includes an active parameter set for a current layer. When the NAL unit includes the active parameter set for the current layer, the video coding device may set an NAL unit header layer identifier associated with the NAL unit to at least one of: zero, a value indicative of the current layer, or a value indicative of a reference layer of the current layer. The NAL unit may be a picture parameter set (PPS) NAL unit. The NAL unit may be a sequence parameter set (SPS) NAL unit.

摘要： Systems and methods for improving efficiency in three-dimensional (3D) look-up table (LUT) coding and/or reducing table size of a 3D LUT may be provided. For example, octants associated with the 3D LUT may be provided for color space segmentation and coding may be performed on an octree associated with the octants where coding may include encoding nodes of the octree associated with the octants and corresponding vertices of the 3D LUT belonging to the nodes. Conversion parameters represented by the nodes are lossy coded with reduced precision. The 3D LUT may also be signaled (e.g., based on a sequence and/or picture level).

摘要： Sketch copy mode may be used to code blocks comprising irregular lines, syntax redundancy may be removed from blocks with special characteristics, and/or run value coding may be simplified. The parsing dependencies in palette coding design may be removed. For example, the context modeling dependency of the syntax element palette_transpose_flag may be removed, for example, by simplifying the corresponding context model. The context modeling of the syntax element palette_mode may be removed, for example, by using run-length coding without using context. The syntax parsing dependencies and/or the syntax signaling dependencies that are related with escape color signaling may be removed. A palette table generation process may handle input screen content video with high bit depths, for example, at the encoder side.

摘要： Methods, systems, and instrumentalities are described to implement single loop decoding, A video decoding device (VDD) may receive a video bitstream, which may include one or more bitstreams (e.g., base layer bitstream, enhanced layer bitstream, etc.) The VDD may generate a hybrid inter-layer reference (H-ILR) picture. The H-ILR picture may be generated based on one or more inputs including, for example, a first layer motion information, a processed (e.g., upsampled) first layer residue signal, a second layer texture information, etc. The first layer motion information may be derived from a compressed first layer motion field or an uncompressed first layer motion field. An H-ILR block of the H-ILR picture may be reconstructed by deriving motion information of the H-ILR block from one or more neighboring H-ILR blocks in the H-ILR picture, for example, when the neighboring blocks are inter-coded.

摘要： In enhancement layer (EL) coding, the temporal candidate(s) may be derived the merge mode and the non-merge mode. Selection of the reference index of a current prediction unit (PU) and of the reference list of a co-located PU may be considered jointly when constructing the temporal candidate of EL for the merge mode. The selection̂) may be made such that a motion vector (MV) scaling operation may be avoided. A selected motion vector prediction candidate may be added to a merging candidate list in a position before that of a spatial motion vector prediction candidate. A selected motion vector prediction candidate may be added to the merging candidate list in place of a spatial motion vector prediction candidate.
