Classification: CPC H | IPC H

Claim 0:
1. A decoding apparatus for a video decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
receive a bitstream, wherein the bitstream comprises image information, wherein the image information includes a picture header associated with a current picture, and the image information includes residual information;
derive slices of the current picture;
obtain, based on the picture header, first flag information related to whether information for an inter slice is present in the picture header and second flag information related to whether information for an intra slice is present in the picture header;
derive prediction samples for blocks in the slices in the current picture based on the first flag information and the second flag information by performing at least one of intra prediction or inter prediction;
derive residual samples based on the residual information; and
generate reconstructed samples based on the prediction samples and the residual samples,
wherein the first flag information and the second flag information are comprised in the picture header of the image information.
