Abstract
An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure is performed by an image decoding apparatus. The image decoding method comprises determining whether a video parameter set (VPS) referenced by a sequence parameter set (SPS) is present, deriving information on inter layer prediction, based on the determination as to whether the video parameter set referenced by the sequence parameter set is present, and reconstructing an image based on the information on inter layer prediction.
