1. A video decoding method performed by a video decoding apparatus, the method comprising:
receiving a bitstream comprising a picture header for a current picture;
parsing, from the picture header, at least one of a first flag related to whether information for an inter slice is present in the picture header or a second flag related to whether information for an intra slice is present in the picture header;
deriving prediction samples for blocks in slices in the current picture based on at least one of the first flag or the second flag, wherein the prediction samples are derived by performing at least one of an intra prediction or an inter prediction; and
generating reconstructed samples based on the prediction samples,
wherein a value of the first flag being equal to 1 is related that the information for the inter slice is present in the picture header, and a value of the second flag being equal to 1 is related that the information for the intra slice is present in the picture header, and
wherein based on the value of the first flag being equal to 1, the information for the inter slice including at least one of a first syntax element representing a difference between base 2 logarithm of a minimum size resulting from quad-tree splitting and base 2 logarithm of a minimum coding block size in the inter slice in the current picture and a second syntax element representing a maximum hierarchy depth for a coding unit resulting from multi-type tree splitting in the inter slice in the current picture is comprised in the picture header.
