Title:
ADAPTIVE ADJUSTMENT OF WEIGHTING PREDICTION PARAMETER PRECISION
Document Type and Number:
WIPO Patent Application WO/2020/251422
Kind Code:
A3
Abstract:
The application refers to a computer-implemented method for a weighting inter prediction process, the method comprising: determining a value of a dynamic range of at least two weights that are to be used for obtaining a weighting parameter to be used in the weighting inter prediction process;obtaining a bit budget value, the bit budget value indicating a number of bits available for the weighting parameter obtained from the at least two weights; and adjusting a precision of the weighting parameter, by right-shifting the value of the weighting parameter by a value that is equal to a difference between the value of the dynamic range and the bit budget value.Furthermore, an encoder and a decoder implementing the above method at least partially are provided.
