Abstract
In a method for decoding an image by a decoding apparatus according to the present disclosure, a current picture is configured to include a single slice, on the basis of a flag indicating whether information on a subpicture exists and a flag indicating whether the subpicture includes a single slice.
Claims3
An image decoding method performed by a decoding apparatus, the method comprising:
- obtaining image information on a current picture from a bitstream;
- and
- decoding the current picture based on the image information,
- wherein the image information includes a first flag related to a presence of subpicture information, and a second flag related to whether each subpicture includes only one slice, and
- wherein a number of slices included in the current picture is derived to be equal to 1 based on the first flag and the second flag.

An image encoding method performed by an encoding apparatus, the method comprising:
- deriving at least one slice by partitioning a current picture;
- and
- encoding image information for the current picture based on the at least one slice,
- wherein the image information includes a first flag related to a presence of subpicture information and a second flag related to whether each subpicture in the current picture includes only one slice, and
- wherein a number of slices included in the current picture is derived to be equal to 1 based on the first flag and the second flag.
2 more elements
A transmission method of data for an image, the transmission method comprising:
- obtaining a bitstream generated by a method, wherein the method comprising performing deriving at least one slice by partitioning a current picture and generating the bitstream by encoding image information for the current picture based on the at least one slice;
- and
- transmitting the data comprising the bitstream,
- wherein the image information includes a first flag related to a presence of subpicture information and a second flag related to whether each subpicture in the current picture includes only one slice, and
- wherein a number of slices included in the current picture is derived to be equal to 1 based on the first flag and the second flag.
