Title:
METHOD AND APPARATUS OF HARMONIZING WEIGHTED PREDICTION AND BI-PREDICTION WITH CODING-UNIT-LEVEL WEIGHT
Document Type and Number:
WIPO Patent Application WO/2020/251423
Kind Code:
A3
Abstract:
Herein, a method for a weighting inter prediction of a to be predicted block is described, the method comprising: obtaining values of bi-prediction with coding unit (CU) level (BCW) weights for the to be predicted block by a fetching operation using an index value specified for the to be predicted block;obtaining values of normalized weights based on the BCW weights;obtaining a value of a linear combined offset (Obi) based on the BCW weights; obtaining a value of a predicted sample (p) of the to be predicted block using a weighted prediction process performed for two reference samples belonging to two reference blocks; and updating the value of the predicted sample using the linear combined offset.Furthermore, a decoder for decoding an encoded video sequence using the method is described.
