Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM FOR STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2020/256470
Kind Code:
A1
Abstract:
The present specification discloses an image encoding/decoding method and device, and a recording medium for storing a bitstream. The image decoding method of the present invention comprises the steps of: deriving slice mode information for at least one slice included in a current picture; deriving slice quantity information on the basis of the slice mode information; deriving tile information of a current slice on the basis of the slice quantity information; and decoding the current slice on the basis of the tile information, wherein the tile information includes tile index presence information and tile index difference value information, wherein the tile index difference value information is not signaled for the last slice included in the current picture.
