Abstract: Systems, methods, and apparatus for video processing are described. The video processing may include video encoding, video decoding or video transcoding. One example method of video processing includes performing a conversion between a video including one or more video regions and a bitstream of the video according to a format rule. The format rule specifies that a variable X indicates whether B slice is allowed or used in a video region. The format rule further specifies that the variable X is based on values of a reference picture list information present flag and/or a field indicating a number of entries in a reference picture list syntax structure.

Abstract: Devices, systems and methods for video processing are described. An example method for video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, a number of intra-coded neighboring blocks of the current block for a combined inter and intra prediction mode according to a rule that specifies a manner of treating a block coded using a palette coding mode in counting the number of intra-coded neighboring blocks for the combined inter and intra prediction mode. The method also includes performing the conversion based on the determining.

Abstract: Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: determining, based on a target motion information between a current frame of a point cloud sequence and a reference frame of the current frame during a conversion between the current frame and a bitstream of the point cloud sequence, whether an attribute inter prediction is performed on the current frame based on the reference frame, the target motion information being used for performing a motion compensation on the reference frame; and performing the conversion based on the determination.

Abstract: One example method of video processing includes implementing, by a processor, a decoder-side motion vector derivation (DMVD) scheme for motion vector refinement during a conversion between a current video block and a bitstream representation of the current video block by deriving parameters based on a deriving rule. The conversion may include compressing the current video block into the bitstream representation or uncompressing the bitstream representation into pixel values of the current video block.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: receiving, at a first device, a metadata file from a second device; and determining a descriptor in a data set in the metadata file, a presence of the descriptor indicating that a representation in the data set is a main stream representation (MSR).

Abstract: Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: performing a conversion between a point cloud sequence and a bitstream of the point cloud sequence based on a tile inventory, the tile inventory being valid starting from a first coded point cloud frame in the bitstream, the first coded point cloud frame immediately following a data unit for the tile inventory in a bitstream order, or the first coded point cloud frame following the data unit in the bitstream order and having a frame counter partially indicated in the data unit. Thereby, the proposed method can advantageously better support the application of the tile inventory.

Abstract: Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: determining, during a conversion between a current frame of a point cloud sequence and a bitstream of the point cloud sequence, at least one neighbor list comprising a set of neighbor points of a current point of the current frame based on geometry information of the set of neighbor points; and performing the conversion based on the at least one neighbor list. Compared with the conventional solution, the proposed method can advantageously improve the point cloud coding efficiency and coding quality.
