    Abstract: Methods, systems and devices for using flexible and efficient partitioning techniques, and in particular, depth calculations for extended quadtree partitioning, are described. An exemplary method for visual media decoding includes applying, to a current visual media block, a partitioning process that splits the current visual media block into exactly four sub-blocks including at least one sub-block that has a size different from half of a width of the current visual media block times half of a height of the current visual media block; decoding, based on a bitstream representation, the four sub-blocks; and decoding, based on the four sub-blocks and the partitioning process, the current visual media block.

    Abstract: Devices, systems and methods for encoding and decoding digital video historical information such as tables containing coding candidates are described. In a representative aspect, a method for video processing includes maintaining an Advanced Motion Vector Prediction (AMVP) candidate list for a conversion between a video block of a video and a bitstream representation of the video with a motion vector precision of M-Pel or sub-pel selected from multiple available motion vector precisions, M being a positive integer. The method also includes comparing an AMVP candidate associated with the video block with existing AMVP candidates in the AMVP candidate list, adding the AMVP candidate to the AMVP candidate list upon determining that the AMVP candidate is different than the existing candidates, and performing the conversion based on the AMVP candidate list.

    Abstract: Devices, systems and methods for encoding and decoding digital video using historical information containing coding candidates are described. In a representative aspect, a method for video processing includes maintaining one or more tables of motion candidates during a conversion between a current video block and a bitstream representation of a video including the current video block, determining that the current video block is coded using a merge mode or an Advanced Motion Vector Prediction (AMVP) mode, and performing, based on the determining, the conversion between the current video block of and the bitstream representation of the video using one or more tables of motion candidates.

    Abstract: Embodiments of the present disclosure provide a solution for visual data processing. A method for visual data processing is proposed. The method comprises: determining, for a conversion between at least one bitstream of visual data and the visual data, a residual representation of the visual data at least based on a first probability distribution parameter of the visual data and a gain parameter, the residual representation representing a residual value compared to a second probability distribution representation of the visual data, the gain parameter adjusting a value range of the residual representation; and performing the conversion based on the residual representation.
