METHOD AND APPARATUS FOR ENCODING/DECODING IMAGE ON BASIS OF PICTURE HEADER INCLUDING INFORMATION RELATING TO CO-LOCATED PICTURE, AND METHOD FOR TRANSMITTING BITSTREAM
METHOD AND APPARATUS FOR ENCODING/DECODING IMAGE ON BASIS OF PICTURE HEADER INCLUDING INFORMATION RELATING TO CO-LOCATED PICTURE, AND METHOD FOR TRANSMITTING BITSTREAM
An image encoding/decoding method and apparatus are provided. The image decoding method according to the present disclosure may comprise the steps of: deriving a temporal motion vector predictor for the current block on the basis of a co-located picture for the current block; deriving a motion vector of the current block on the basis of the temporal motion vector predictor; and generating a prediction block of the current block on the basis of the motion vector, wherein the co-located picture is determined on the basis of identification information of the co-located picture, which is included in a slice header of the current slice including the current block, and if the slice header does not include identification information of the co-located picture, the co-located picture is determined on the basis of identification information of the co-located picture, which is included in a picture header of the current picture including the current block.
