子PU级先进残余预测
摘要：
译码单元CU的预测单元PU拆分成包含第一子PU和第二子PU的两个或两个以上子PU。获得用于所述第一子PU的第一类型的第一运动向量，且获得用于所述第二子PU的所述第一类型的第二运动向量。获得用于所述第一子PU的第二类型的第三运动向量，且获得用于所述第二子PU的所述第二类型的第四运动向量。所述第二类型不同于所述第一类型。使用所述第一和第三运动向量根据先进残余预测ARP对对应于所述第一子PU的所述CU的第一部分进行译码。使用所述第二和第四运动向量根据ARP对对应于所述第二子PU的所述CU的第二部分进行译码。
摘要（英）：

A prediction unit (PU) of a coding unit (CU) is split into two or more sub-PUs including a first sub-PU and a second sub-PU. A first motion vector of a first type is obtained for the first sub-PU and a second motion vector of the first type is obtained for the second sub-PU. A third motion vector of a second type is obtained for the first sub-PU and a fourth motion vector of the second type is obtained for the second sub-PU, such that the second type is different than the first type. A first portion of the CU corresponding to the first sub-PU is coded according to advanced residual prediction (ARP) using the first and third motion vectors. A second portion of the CU corresponding to the second sub-PU is coded according to ARP using the second and fourth motion vectors.
