動きベクトル予測方法

摘要

The invention provides a motion prediction method. First, a plurality of motion vector predictors is obtained to be included in a candidate set for motion prediction of a current unit of a current frame. Whether the motion vector predictors in the candidate set are equal to each other is then determined. When the motion vector predictors in the candidate set are equal to each other, one or more backup motion vector predictors are included in the candidate set and a final motion vector predictor from the candidate set is selected. A motion vector of the current unit is then predicted according to the final motion vector predictor of the candidate set.
