Abstract: A method for video processing comprises: determining, during a conversion between a target video block of a video and a bitstream of the video, an intra block copy (IBC)-based mode to be applied for the target video block based on at least one of: a mode based on affine motion compensated prediction, an affine IBC merge mode with block vector differences (MBVD), an intra template matching for IBC mode (TM_IBC), wherein a derived block vector (BV) is used as base candidates for the MBVD, an intra template matching for IBC mode (TM_IBC), wherein a derived BV is used as BV prediction candidate for IBC non-merge mode, an IBC prediction mode based on multi-hypothesis, a mode based on overlapped block motion compensation (OBMC), a mode based on geometric partitioning with the MBVD, or a mode based on geometric partitioning with TM; and performing the conversion based on the IBC-based mode.

Abstract: Embodiments for video processing, including video coding, video decoding and video transcoding are described. One example method includes performing a conversion between a video having one or more layers having one or more video pictures having one or more subpictures and a bitstream of the video according to a rule, wherein the rule defines network abstraction layer (NAL) units to be extracted from a bitstream during a sub-bitstream extraction process to output a sub-bitstream, wherein the rule further specifies that one or more inputs to the sub-bitstream extraction process include a target output layer set (OLS) index (targetOlsIdx) that identifies an OLS index of a target OLS and is equal to an index to a list of OLSs specified by a video parameter set, and wherein the one or more inputs satisfy a set of conditions.

Abstract: In a promotion offering system, a promotion offering may be presented to a consumer on more than one occasion. The previous presentation of the promotion to the consumer may affect a subsequent presentation of the same promotion to the same consumer. The present invention provides an apparatus and method for analyzing the effect a previous presentation of a promotion may have on a consumer when the promotion is presented to the consumer at a subsequent time.

Abstract: Devices, systems and methods for encoding and decoding digital video using a look-up tables (LUTs) containing motion candidates are described. A method of video processing includes maintaining one or more tables, at least one table of the one or more tables is associated with one or more entries, deriving, based on a first set of motion candidates in the at least one table, a second set of motion candidates, and performing, based on the second set of motion candidates, a conversion between a current block of a video and a bitstream representation of the video.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a current video block of a video and a bitstream of the video, a cost based on at least two error metrics associated with two target blocks of the video, the cost indicting a degree of distortion between the two target blocks; refining coding data of the current video block based on the cost and the two target blocks; and performing the conversion based on the refined coding data. Compare with the conventional solution, the proposed method can advantageously improve the coding quality and the coding efficiency.

Abstract: Embodiments provide a computer-executable method, computer system and non-transitory computer-readable medium for programmatically assessing consumer sentiment with regard to an attribute descriptor associated with a commercial entity and/or a commercial item. A computer-executed method includes programmatically accessing, via a network device, text of a consumer review and in indication of an attribute descriptor included in the text of the consumer review. The method also includes executing a consumer review processing engine to programmatically analyze the text of the consumer review to generate a sentiment score associated with the attribute descriptor in the context of the consumer review. The method further includes storing, on a non-transitory computer-readable storage device, an indication of the attribute descriptor and the generated sentiment score in association with the commercial entity and/or the commercial item.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing comprises: reordering, during a conversion between a current video block of a video and a bitstream of the video, a plurality of candidate signs of a motion vector difference (MVD) for a motion candidate of the current video block; and performing the conversion based on the reordered plurality of candidate signs. Compared with the conventional solution, the proposed method can advantageously improve coding efficiency and coding quality.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target video block of a video and a bitstream of the video, a set of motion vector prediction (MVP) candidates of the target video block based on decoded information of the target video block; sorting the set of MVP candidates based on respective template matching costs of the set of MVP candidates; and performing the conversion based on the sorting.
