    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 current frame is a non-reference frame which is not referred to by other frames for motion prediction is then determined. When the current frame is not the non-reference frame, any motion vector predictor corresponding to a previously coded frame is removed from the candidate set, and a motion vector of the current unit is predicted according to the motion vector predictors of the candidate set.

    摘要： An exemplary method for decoder-side motion vector derivation (DMVD) includes: checking a block size of a current block to be encoded and accordingly generating a checking result; and utilizing a DMVD module to refer to the checking result to control conveyance of first DMVD control information which is utilized for indicating whether a DMVD coding operation is employed to encode the current block. When the checking result indicates a predetermined criterion is satisfied, the first DMVD control information is sent in a bitstream; otherwise, the first DMVD control information is not sent.
