Image encoding/decoding method and device for signaling hrd parameters, and computer-readable recording medium in which bitstream is stored

Abstract

Disclosed herein are an image encoding/decoding method and apparatus for signaling hypothetical reference decoder (HRD) related parameters, and a method of transmitting a bitstream. An image decoding method may comprise obtaining first information specifying the number of one or more hypothetical reference decoder (HRD) parameter syntax structures in a video parameter set (VPS), obtaining the one or more HRD parameter syntax structures from the VPS based on the first information, obtaining second information on mapping between one or more multi-layer output layer sets (OLSs) and the one or more HRD parameter syntax structures from the VPS based on the first information, selecting a HRD parameter syntax structure that applies to a current OLS based on the second information, and processing the current OLS based on the selected HRD parameter syntax structure.
