Abstract
A method of video decoding is provided. In the method, a coded video bitstream of a current picture is received. The current picture is divided into a plurality of rows of coding tree units (CTUs). Coding blocks in a first CTU row of the plurality of rows of CTUs are decoded based on motion vector information stored in a history-based motion vector prediction (HMVP) buffer. The motion vector information stored in the HMVP buffer is updated as the coding blocks in the first CTU row are decoded. The HMVP buffer is updated to include the motion vector information of the coding blocks in a first CTU of the first CTU row after the coding block at an end of the first CTU row is decoded.
