Abstract:
A method of video decoding for a video decoder that includes acquiring a current picture from a coded video bitstream. The method further includes selecting, from a history buffer that stores motion vector predictors of N previously decoded blocks. The method further includes selecting, from the history buffer, a second motion vector predictor of a second neighboring block of the current block. The method further includes selecting a first temporal block included in a previously decoded reference picture associated with the current picture, the first temporal block including a third motion vector predictor, the first temporal block being one of (i) neighboring to a collocated block of the current block and (ii) within the collocated block. The method further including determining a motion vector predictor of the current block using a weighted average of the first motion vector predictor, the second motion vector predictor, and the third motion vector predictor.

Claim (Index 20):
A non-transitory computer readable medium having instructions stored therein, which when executed by a processor in a video decoder causes the video decoder to execute a method comprising:\n acquiring a current picture from a coded video bitstream; selecting a first motion vector predictor of a first neighboring block of a current block, the first motion vector is selected from a first-in-first-out (FIFO) history buffer that stores motion vector predictors of N previously decoded blocks from the current picture, each motion vector predictor being stored in association with x and y coordinates of a corresponding one of the previously decoded blocks, wherein the selected first motion vector predictor is a last entry in the history buffer among entries with a x coordinate that is less than a x coordinate of the current block, N being an integer greater than 1; selecting, from the history buffer, a second motion vector predictor of a second neighboring block of the current block; selecting a first temporal block included in a previously decoded reference picture associated with the current picture, the first temporal block including a third motion vector predictor, the first temporal block being one of (i) neighboring to a collocated block of the current block and (ii) within the collocated block; and determining a motion vector predictor of the current block using a weighted average of the first motion vector predictor, the second motion vector predictor, and the third motion vector predictor.
