Abstract
Video encoding and decoding techniques for bi-prediction with weighted averaging are disclosed. According to certain embodiments, a computer-implemented video signaling method includes signaling, by a processor to a video decoder, a bitstream including weight information used for prediction of a coding unit (CU). The weight information indicates: if weighted prediction is enabled for a bi-prediction mode of the CU, disabling weighted averaging for the bi-prediction mode.
