INTER PREDICTION METHOD AND APPARATUS IN IMAGE/VIDEO CODING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18382246 titled 'INTER PREDICTION METHOD AND APPARATUS IN IMAGE/VIDEO CODING SYSTEM
Simplified Explanation
The video decoding method described in the patent application involves parsing flags associated with weighted prediction from a bitstream, parsing a prediction weighted table syntax from a picture header of the bitstream based on the flags, generating prediction samples for a current block in a current picture using syntax elements in the prediction weighted table syntax, and generating reconstructed samples based on the prediction samples. The flags include one flag for determining if weighted prediction is applied to slices referring to a picture parameter set of the bitstream, and another flag for indicating if information related to weighted prediction is present in the picture header.

Original Abstract Submitted
A video decoding method performed by a video decoding apparatus, according to the present document, comprises the steps of: parsing, from a bitstream, flags associated with weighted prediction; parsing a prediction weighted table syntax from a picture header of the bitstream on the basis of the flags; generating prediction samples regarding a current block in a current picture on the basis of syntax elements in the prediction weighted table syntax; and generating reconstructed samples on the basis of the prediction samples, wherein the flags comprise a first flag associated with whether the weighted prediction is applied to slices referring to a picture parameter set of the bitstream, and a second flag associated with whether information related to the weighted prediction is present in the picture header, and the second flag may be parsed from the picture parameter set on the basis of the first flag.
