Abstract:
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.
