摘要

用于编码单元的视讯编码的局部多重假设预测的执行方法及装置，其中该方法包含：将编码单元分割成复数个次编码单元，以及对每一次编码单元进行运动向量预测。更进一步来说，对每一次编码单元进行运动向量预测的步骤包含：由复数个其他次编码/编码单元中，取得复数个运动向量以供复数个次编码单元的特定次编码单元执行多重假设运动补偿。该方法另包含：依据复数个运动向量来对特定次编码单元执行多重假设运动补偿，尤指利用复数个其他次编码/编码单元的复数个像素值的线性组合来做为特定次编码单元的预测像素值。本发明亦提供相关装置。; and performing motion vector prediction of each of the sub-coding units. More particularly, the step of performing motion vector prediction of each of the sub-coding units further includes: obtaining a plurality of motion vectors for multihypothesis motion compensation of a specific sub-coding unit of the sub-coding units from a plurality of other sub-coding/coding units. The method further includes performing multihypothesis motion compensation on the specific sub-coding unit according to the plurality of motion vectors, and more particularly, includes utilizing a linear combination of a plurality of pixel values of the plurality of other sub-coding/coding units as a predicted pixel value of the specific sub-coding unit. An associated apparatus is also provided.
