摘要： Methods, systems, apparatuses for video processing are described. A method for processing video includes performing a conversion between a video and a bitstream of the video according to a format rule, and wherein the format rule specifies to include, in a general constraint syntax structure associated with the video, one or more general constraint flags indicating whether corresponding syntax elements are included in a sequence parameter set (SPS) and/or a picture parameter set (PPS) and/or a picture header (PH) and/or a slice header (SH) or to constrain values of the syntax elements in the SPS and/or the PPS and/or the PH and/or the SH.

摘要： A method includes performing a conversion between a video including a video picture including one or more tiles and a bitstream of the video. The video picture refers to a picture parameter set, and the picture parameter set conforms to a format rule specifying that the picture parameter set includes a list of column widths for N tile columns, where N is an integer. An (N−1)-th tile column exists in the video picture and the (N−1)-th tile column has a width that is equal to an (N−1)-th entry in a list of explicitly included tile column widths plus one number of coding tree blocks.

摘要： A method includes performing a conversion between a video comprising a video picture that includes one or more subpictures and a bitstream of the video according to a format rule. The format rule specifies that whether each of the one or more subpictures in the video picture includes a single slice is determined based on a constraint flag.

摘要： Methods, apparatus, systems for video processing, including video encoding or video decoding are described. One example method includes performing a conversion between a video including a video picture that includes one or more subpictures and a bitstream of the video. The bitstream conforms to a format rule specifying that a first syntax element indicating whether an operation is performed across a boundary of a subpicture in the coded layer video sequence is selectively included responsive to a number of subpictures in the video picture.

摘要： Techniques for video processing, including video coding, video decoding and video transcoding are described. One example method includes performing a conversion between a video including a video picture including a video tile including one or more slices and a bitstream of the video according to a rule. The rule specifies that a second slice in a tile that includes a first slice in a picture has a height that is represented in a unit of coding tree units. The first slice has a first slice index, and the second slice has a second slice index that is determined based on the first slice index and a number of explicitly provided slice heights in the video tile. The height of the second slice is determined based on the first slice index and the second slice index.

摘要： A method includes performing a conversion between a video including video pictures that include one or more subpictures and a bitstream of the video. The bitstream conforms to a format rule specifying that one or more syntax structures are constrained based on a constraint flag of a syntax element that includes general constraints information.

摘要： Methods, apparatus, systems for video processing, including video encoding or video decoding are described. One example method includes determining an output sub-bitstream by extracting a sub-bitstream of one or more target subpictures from a bitstream of a video including video pictures. At least one of the video pictures includes one or more subpictures. The output sub-bitstream conforms to a format rule specifying that the one or more target subpictures is represented as a single subpicture in the output sub-bitstream.

摘要： Methods, apparatus, systems for video processing, including video encoding or video decoding are described. One example method includes performing a conversion between a video including a video picture that includes a video slice and a bitstream of the video. The bitstream conforms to a format rule specifying that a slice type of the video slice determines a manner by which certain information from a picture header for the video picture is inherited by a slice header of the video slice.
