    Abstract: According to the present document, a video decoding method performed by a video decoding device may comprise the steps of: parsing a first flag and a second flag from a bitstream, wherein the first flag is related to whether weighted prediction is applied to slices referring to a picture parameter set within the bitstream, and the second flag is related to whether information relating to the weighted prediction exists in a picture header within the bitstream; parsing a prediction weighted table syntax from the picture header on the basis of the first flag and the second flag; generating prediction samples for a current block in a current picture on the basis of syntax elements within the prediction weighted table syntax; generating residual samples on the basis of residual information obtained from the bitstream; and generating reconstructed samples on the basis of the prediction samples and the residual samples, wherein the second flag is parsed from the picture parameter set on the basis of the first flag.

    Abstract: A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: parsing, from a picture parameter set of a bitstream, a first flag related to whether a weighted prediction is applied to slices referring to the picture parameter set; parsing, from the picture parameter set, a second flag related to whether information about the weighted prediction is present in a picture header of the bitstream or is present in a slice header of the bitstream on the basis of the first flag; parsing a prediction weighted table syntax from the picture header or the slice header on the basis of the first flag and the second flag; generating prediction samples for the current block by performing weighted prediction for the 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.

    Abstract: A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: acquiring image information from a bitstream, the image information including a picture header related to a current picture, and the current picture including a plurality of slices; parsing, from the picture header, a first flag indicating whether information necessary for an inter prediction operation is in the picture header and/or a second flag indicating whether information necessary for an intra prediction operation is in the picture header; parsing, from the picture header, the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation on the basis of the first flag and/or the second flag; and generating prediction samples by performing intra prediction and/or inter prediction for a current block in the current picture on the basis of the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation.
