摘要： The present disclosure provides systems and methods for processing video content. The method can include: receiving data representing a first block and a second block in a picture, the data comprising a plurality of chroma samples associated with the first block and a plurality of luma samples associated with the second block; determining an average value of the plurality of luma samples associated with the second block; determining a chroma scaling factor for the first block based on the average value; and processing the plurality of chroma samples associated with the first block using the chroma scaling factor.

摘要： The present disclosure provides methods for picture processing. The method can include: receiving a bitstream comprising a set of pictures; determining, according to the received bitstream, whether a virtual boundary is signaled at a sequence level for the set of pictures; in response to the virtual boundary being signaled at the sequence level, determining a position of the virtual boundary for the set of pictures, the position being bounded by a range signaled in the received bitstream; and disabling in-loop filtering operations across the virtual boundary.

摘要： The present disclosure provides a computer-implemented method for encoding video. The method includes coding one or more first flags in a sequence parameter set (SPS) of a bitstream, and coding at least one second flag in the SPS if one or more coding modes are enabled for a video sequence associated with the SPS. The one or more first flags indicate whether the one or more coding modes are enabled for the video sequence. The at least one second flag indicates whether a multi-level control is activated for the one or more coding modes.

摘要： The present disclosure provides a computer-implemented method for encoding or decoding video. The method includes encoding or decoding, in a plurality of picture parameter sets (PPS) associated with pictures of a coded layer video sequence (CLVS), corresponding first PPS flags indicating whether pictures are allowed to be partitioned into a plurality of tiles or slices. In a first PPS, a corresponding first PPS flag with a first value indicates a first picture of the CLVS is unpartitioned, and in a second PPS, another corresponding first PPS flag with a second value being different from the first value indicates that a second picture of the CLVS is allowed to be partitioned.

摘要： The present disclosure provides systems and methods for signaling and using a palette mode in video processing. According to certain disclosed embodiments, an exemplary video processing method includes: receiving a first palette entry for palette coding a target coding unit (CU); determining whether the target CU is part of a single-tree slice; determining whether the target CU is coded with separate luma and chroma trees; and in response to the target CU being determined to be part of a single-tree slice and be coded with separate luma and chroma trees, decoding a first component of the target CU based on the first palette entry, and decoding a second component of the target CU based on a default palette entry.

摘要： The present disclosure provides method and apparatus for motion field storage in video coding. An exemplary method includes: determining whether a first uni-prediction motion vector for a first partition of a block and a second uni-prediction motion vector for a second partition of the block are from a same reference picture list; and in response to the first uni-prediction motion vector and the second uni-prediction motion vector being determined to be from the same reference picture list, storing, in a motion field of the block, one of the first uni-prediction motion vector and the second uni-prediction motion vector for a subblock located in a bi-predicted area of the block.

摘要： The present disclosure provides a video data processing method for cross-component sample adaptive offset. The method includes receiving a bitstream; determining a category index of a target chroma sample, wherein the category index is determined based on a first reconstructed value associated with a co-located luma sample and a second reconstructed value associated with the target chroma sample; decoding an index indicating an offset corresponding to the category index from the bitstream; determining the offset based on the index; and adding the offset to a third reconstructed value associated with the target chroma sample.
