Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: reordering a plurality of samples in a region of a video during a conversion between the region and a bitstream of the video; and performing the conversion based on the reordered plurality of samples. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency.

Abstract: Systems, apparatus, methods, and non-transitory media for providing prescient and adaptive point-of-sale services via electronic networks are discussed herein. Some embodiments may include a system with one or more servers. The one or more servers may be configured to generate digital consumer tokens and provide the digital consumer tokens to consumer devices for sharing with merchant devices. When a merchant device receives the digital consumer token, the merchant device may forward the digital consumer token to the one or more servers in exchange for consumer data to facilitate consumer service. In some embodiments, the one or more servers may be configured to provide point-of-sale interfaces that adapt to different consumer preferences or consumer device signals. Some embodiments may provide for consumer interfaces that allow consumers to manage their electronic identity at various (e.g., merchant) locations.

Abstract: A method for video processing is proposed. The method comprises: deriving, during a conversion between a target unit of a video and a bitstream of the target unit, an intra prediction mode (IPM) of the target unit for at least one chroma component (2610), the target unit being applied with a target coding tool; obtaining a prediction of the target unit for the at least one chroma component using the IPM (2620); and performing the conversion based on the prediction of the target unit for the at least one chroma component (2630).

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 block of a video and a bitstream, reference samples of a sub-template of the current block based on a first set of reference samples of the sub-template in a first reference list and a second set of reference samples of the sub-template in a second reference list; and determining a target motion candidate list based on the reference samples of the sub-template. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency.

Abstract: Devices, systems and methods for digital video coding, which includes matrix-based intra prediction methods for video coding, are described. In a representative aspect, a method for video processing includes encoding a current video block of a video using a matrix intra prediction (MIP) mode in which a prediction block of the current video block is determined by performing, on previously coded samples of the video, a boundary downsampling operation, followed by a matrix vector multiplication operation, and selectively followed by an upsampling operation; and adding, to a coded representation of the current video block, a syntax element indicative of applicability of the MIP mode to the current video block using arithmetic coding in which a context for the syntax element is derived based on a rule.

Abstract: In an exemplary aspect, a method for visual media processing includes identifying a boundary at a vertical edge and/or a horizontal edge of two video blocks; calculating a boundary strength of a filter based on at least one of the two video blocks crossing a vertical edge or a horizontal edge is coded using a combined intra-inter prediction (CIIP) mode; deciding whether to turn on or off the filter; selecting a strength of the filter in case the filter is turned on; and performing, based on the selecting, a deblocking filter (DB) process to the video blocks.

Abstract: Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, whether a combined inter and intra prediction (CIIP) coding technique is to be applied to the current block based on a characteristic of the current block. The CIIP coding technique uses an intermedia inter prediction value and an intermedia intra prediction value to derive a final prediction value of the current block. The method also includes performing the conversion based on the determining.
