Title:
IMAGE ENCODING/DECODING METHOD AND APPARATUS BASED ON SUBPICTURE INFORMATION ALIGNED BETWEEN LAYERS, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2021/201617
Kind Code:
A1
Abstract:
Provided are an image encoding/decoding method and apparatus. The image decoding method according to the present disclosure comprises the steps of: obtaining subpicture information from a bitstream; deriving one or more subpictures in a current picture on the basis of the subpicture information; and decoding a current subpicture in the current picture on the basis of the subpicture information, wherein the subpicture information includes a first flag indicating whether each of the one or more subpictures is treated as one picture, and, on the basis that the bitstream includes at least one first layer referencing a current layer including the current picture, the first flag for a first subpicture that is included in the at least one first layer and corresponds to the current subpicture and the first flag for the current subpicture may have the same value.
