摘要
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.
