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.
Claims20
A computer-implemented signaling method, comprising:
- signaling, by a processor to a video decoder, a bitstream including weight information used for prediction of a coding unit (CU), the weight information indicating:
- in response to weighted prediction being enabled for a bi-prediction mode of the CU, performing weighted bi-prediction and disabling weighted averaging for the bi-prediction mode.
A device comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to cause the device to:
- signal, to a video encoder, a bitstream including weight information used for prediction of a coding unit (CU), the weight information indicating:
- if weighted prediction is enabled for a bi-prediction mode of the CU, perform weighted bi-prediction and disable weighted averaging for the bi-prediction mode.
A non-transitory computer-readable medium storing a set of instructions that is executable by one or more processors of a device to cause the device to perform a method comprising:
- signaling, to a video decoder, a bitstream including weight information used for prediction of a coding unit (CU), the weight information indicating:
- if weighted prediction is enabled for a bi-prediction mode of the CU, performing weighted bi-prediction and disabling weighted averaging for the bi-prediction mode.
