Method and apparatus for parsing error robustness of temporal motion vector prediction

摘要

A method and apparatus for deriving a motion vector predictor (MVP) are disclosed. The MVP is selected from spatial MVP and temporalone or more MVP candidates. The method determines a value of a flag in a video bitstream, where the flag is utilized for selectively disabling use of one or more temporal MVP candidates for motion vector prediction. The method selects, based on an index derived from the video bitstream, the MVP from one or more non-temporal MVP candidates responsive to the flag indicating that said one or more temporal MVP candidates are not to be utilized for motion vector prediction. Further, the method provides the MVP for the current block.
