Abstract

Disclosed herein are an image encoding/decoding method and apparatus, and a recording medium storing a bitstream. The image decoding method according to the present invention includes: deriving slice mode information for at least one slice comprised in a current picture; deriving information on the number of slices based on the slice mode information; deriving tile information of a current slice based on the information on the number of slices; and, decoding the current slice based on the tile information. Herein, the tile information includes tile index presence information and tile index difference value information, and the tile index difference value information is not signaled for a last slice included in the current picture.
