Abrégé
(EN)
A method and apparatus for deriving directional-priority based candidates for a block coded in Inter, or Merge or Skip mode are disclosed. One or more motion vectors associated with one or more previously coded blocks for a current block are determined first. One or more directional-priority based candidates for the current block are derived by searching through the previously coded blocks according to a priority order associated with prediction direction of the motion vectors. The motion vectors having a first prediction direction are selected with a higher priority than the motion vectors having a second prediction direction. The derived directional-priority based candidates are inserted into a candidate list. The motion vector predictor (MVP) or Merge/Skip candidate is selected from the candidate list for coding the current block in Inter, or Merge or Skip mode.

本发明提供一种推导用于在帧间、或合并或跳过模式中编码的块的基于方向优先级的候选的方法和装置。首先,与用于当前块的一个或多个先前编码块相关联的一个或多个运动矢量被确定。通过根据与运动矢量的预测方向相关联的优先级顺序搜索先前编码块来导出当前块的一个或多个基于方向优先级的候选。具有第一预测方向的运动矢量被选择为具有比具有第二预测方向的运动矢量更高的优先级。推导的基于方向优先级的候选被插入到候选列表中。从候选列表中选择运动矢量预测子(MVP)、或合并/跳过候选,以在帧间、或者合并或跳过模式中对当前块进行编码。
