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.
