    Abstract: The present disclosure provides methods and devices of construct a candidate merge list for Intra block copy (IBC) mode, the method comprising: inserting a block vector of a left neighboring block of a current block into an initial merge list, when the left neighboring block is available and the left neighboring block is using IBC mode; inserting a block vector of an above neighboring block of the current block into the initial merge list, when the above neighboring block is available, the above neighboring block is using IBC mode and the block vector of the above neighboring block is not same as the block vector of the left neighboring block; inserting a block vector of the last candidate in a history based motion vector predictor (HMVP) into the initial merge list; obtaining a block vector of the current block according to the initial merge list.

    Abstract: A partitioning method comprises determining whether a current block of a picture is a boundary block and whether the size of the current block is larger than a minimum allowed quadtree leaf node size; and if the current block is the boundary block and the size of the current block is not larger than the minimum allowed quadtree leaf node size (MinQTSize), applying forced binary tree (BT) partitioning to the current block. A method comprises making a determination that a current block of a picture is a boundary block and that a size of the current block is less than or equal to a minimum allowed quadtree (QT) leaf node size (MinQTSize); and applying, in response to the determination, forced binary tree (BT) partitioning to the current block.

    Abstract: A system and method for processing a video stream are provided. When coding or decoding a video stream a de-blocking filtering may be applied for reducing discontinuities caused by use of a block-based video coding. The de-blocking filtering is performed using a filter grid. The size of the filter grid is chosen adaptively based on the processing parameters. The adaptive size of the filtering grid is determined based on the number of samples used and modified in de-blocking filtering of an edge of a coding block. The filtering grid may be used both for vertical and horizontal edge filtering.
