Abstract: A mechanism for processing video data is disclosed. A value of an annotated region (AR) object label index of an i-th AR object index (ar_object_label_idx[ar_object_idx[i]]) syntax element is determined. The ar_object_label_idx[ar_object_idx[i]] syntax element is specified to be in a range of N to M, where N and M are integers and N is less than M. A conversion is performed between a visual media data and a bitstream based on the ar_object_label_idx[ar_object_idx[i]] syntax element.

Abstract: A method of video processing is provided. The method includes: determining, for a conversion between a video block of a video and a bitstream of the video, a selected neighboring sample list according to an order, wherein the order specifies that above neighboring samples are added to the selected neighboring sample list before left neighboring samples, and performing the conversion based on a cross-component linear model, wherein parameters of a cross-component linear model is derived using a derivation method that is based on samples from the selected neighboring sample list.

Abstract: Methods, apparatus and systems for processing video are described. One example method includes performing a conversion between a video comprising a video unit and a bitstream of the video, wherein the bitstream conforms to a format rule, and wherein the format rule specifies that a first syntax element indicating whether an in-loop filtering operation is performed across tile boundaries is selectively included in the bitstream responsive to whether or how the video unit is partitioned into tiles.

Abstract: A method implemented by a video coding apparatus. The method includes determining that a multiview acquisition information (MAI) supplemental enhancement information (SEI) message is present in a first access unit (AU) of a coded video sequence (CVS) whenever any MAI SEI message is present in any AU of the CVS; and performing a conversion between a video and a bitstream of the video based on the MAI SEI message. A corresponding video coding apparatus and non-transitory computer readable medium are also disclosed.

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 block of a video and a bitstream of the video according to a rule. The conversion is based on an adaptive motion vector difference resolution (AMVR) tool, and the rule specifies that selection of a context for a first bin within a bin string of a first syntax element that specifies the resolution of the motion vector difference associated with an AMVR shift is derived based on usage of a coding mode for the block.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines whether a block is dyadic or non-dyadic. The mechanism also enables a coding tool associated with inter prediction when the block is determined to be dyadic. The mechanism also disables the coding tool when the block is determined to be non-dyadic. A conversion between a visual media data and a bitstream is performed by applying inter prediction to the block.
