Original Abstract Submitted

An image encoding/decoding method, a bitstream transmission method, and a computer-readable recording medium storing a bitstream are provided. The image decoding method according to the present disclosure, performed by an image decoding apparatus, comprises the steps of: acquiring first information on the basis that the prediction direction of a current block is bidirectional; on the basis that the first information indicates that different prediction types are applied to the respective prediction directions of the current block, deriving, from reference blocks, at least one bidirectional motion information candidate corresponding to the different prediction types; and on the basis of any one of the at least one bidirectional motion information candidate, bidirectionally predicting the current block with the different prediction types, wherein the different prediction types are a sub-block unit (sub PU) prediction type and a non-sub-block unit (non-sub PU) prediction type.
