Method and Apparatus of Temproal Motion Vector Prediction

摘要

An apparatus and method for temporal motion vector prediction for a current block in a picture are disclosed. In the present method, one temporal block in a first reference picture in a first list selected from a list group comprising list 0 and list 1 is determined. When the determined temporal block has at least one motion vector, a candidate set is determined based on the motion vector of the temporal block. The temporal motion vector predictor or temporal motion vector predictor candidate or temporal motion vector or temporal motion vector candidate for the current block is determined from the candidate set by checking a presence of a motion vector pointing to a reference picture in a first specific list in said at least one motion vector, wherein the first specific list is selected from the list group based on a priority order.

1. A method of deriving a temporal motion vector predictor or temporal motion vector predictor candidate or temporal motion vector or temporal motion vector candidate for a current block in a current picture, the method comprising:
determining one temporal block in a first reference picture in a first list selected from a list group comprising list 0 and list 1; when said one temporal block has at least one motion vector, determining a candidate set based on said at least one motion vector, wherein said determining the candidate set comprises generating at least one scaled motion vector from said at least one motion vector; and determining the temporal motion vector predictor or temporal motion vector predictor candidate or temporal motion vector or temporal motion vector candidate for the current block from the candidate set by checking a presence of a motion vector pointing to a reference picture in a first specific list in said at least one motion vector, wherein the first specific list is selected from the list group based on a priority order.
