Abstract: 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 and a bitstream of the video according to a format rule. The format rule specifies that constraints on values of one or more first syntax elements in an adaptation parameter set are defined based on semantics of second syntax elements in a picture header and/or a slice header when a picture or a slice refers to the adaptation parameter set.

Abstract: Merchandise content is aggregated from numerous merchant sources and presented on computing devices of individual users. Users are able to purchase select individual merchandise items by performing a simplified action, such as a screen tap on a touchscreen device. When the user performs the action, a series of actions are performed programmatically and/or automatically on behalf of the user to initiate and complete the transaction for the selected merchandise item from the merchant source.

Abstract: Devices, systems and methods for sub-block based prediction are described. In a representative aspect, a method for video encoding includes partitioning, based on a first rule, a luma component of a block of video data into a first set of sub-blocks. The method also includes partitioning, based on a second rule, a first chroma component of the block of video data into a second set of sub-blocks. The first and the second set of sub-blocks include different numbers of sub-blocks. The method also includes performing a subsequent motion prediction based on the first and the second set of sub-blocks.

Abstract: A method for video processing is provided to include: performing a conversion between a current video block of a video and a coded representation of current video block, wherein the conversion uses a coding mode in which the current video block is constructed based on a first domain and a second domain and/or chroma residue is scaled in a luma-dependent manner, and wherein information used for the coding mode is signaled in a parameter set that is different from a sequence parameter set (SPS), a video parameter set (VPS), a picture parameter set (PPS), or an adaptation parameter set (APS) used for carrying adaptive loop filtering (ALF) parameters.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, for a conversion between a current video block of a video and a bitstream of the video, that a first prediction mode is applied to the current block, reordering, in the first prediction mode, at least a first set of block vector difference (BVD) candidates of multiple BVD candidates corresponding to a first base candidate according to at least one criterion; deriving, based on the reordered BVD candidates, a block vector for the current video block; and performing the conversion based on the motion information.

Abstract: Methods, systems, and devices for performing entropy coding for a palette escape symbol in palette mode coding and decoding are described. An example method for video processing includes performing a conversion between a video having one or more video regions including a current video block and a bitstream representation of the video, wherein the bitstream representation conforms to a format rule that the current video block is coded using a palette mode coding tool, wherein a binarization of an escape symbol for the current video block uses an exponential-Golomb (EG) code of order K, wherein K is a non-negative integer that is unequal to three, and wherein the palette mode coding tool represents the current video block using a palette of representative color values and wherein the escape symbol is used for a sample of the current video block coded without using the representative color values.

Abstract: Provided herein are method, apparatus, and computer program products for generating a first and second three dimensional interactive environment. The first three dimensional interactive environment may contain one or more engageable virtual interfaces that correspond to one or more items. Upon engagement with a virtual interface the second three dimensional interactive environment is produced to virtual simulation related to the one or more items.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: obtaining, for a conversion between a current video block of a video and a bitstream of the video, a value for a metric of a blending region in a direction, the blending region being comprised in a target region associated with the current video block, the value being determined from a plurality of predetermined values for the metric, values for samples of the blending region being determined based on values for samples of a first part of the target region and values for samples of a second part of the target region; and performing the conversion based on the value for the metric.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: obtaining, for a conversion between a current video block of a video and a bitstream of the video, a first motion vector (MV) for a target video block, the target video block being determined by applying a sample adjusting process to a plurality of samples of the current video block; adjusting the first MV based on a second MV generated for the target video block; and performing the conversion based on the adjusted first MV.

Abstract: Method of processing video data is disclosed. A method for video processing includes dividing, for a conversion between a block of a video and a bitstream of the block, syntax elements associated with the block into different groups of syntax elements; applying controls on the different groups of syntax elements separately; and performing the conversion based on the controls.
