Original Abstract Submitted
In a method of video decoding performed by a decoder, a current picture is obtained from a coded video bitstream. The current picture is divided into a plurality of units and divided into a plurality of tiles. Each tile includes at least one unit of the plurality of units. A first current unit in a first tile of the plurality of tiles is decoded. A first HMVP buffer is updated with a motion vector of the first current unit that has been decoded. A position of the first current unit in the first tile of the plurality of tiles is determined. The first HMVP buffer is reset when the first current unit is located in a first column of the first tile.
