Abstract

See full text

A video decoding method performed by a video decoding device according to the present document may comprise the steps of: acquiring image information from a bitstream, wherein the image information includes a picture header associated with a current picture, and the current picture includes multiple slices; on the basis of the picture header, acquiring at least one of a first flag indicating whether information required for an inter-prediction operation exists in the picture header and a second flag indicating whether information required for an intra-prediction operation exists in the picture header; on the basis of at least one of the first flag and the second flag, generating prediction samples by performing at least one of intra-prediction and inter-prediction with respect to a current block in the current picture; generating residual samples on the basis of residual information acquired from the image information; and generating reconstruction samples on the basis of the prediction samples and the residual samples.
