Video encoding/decoding method and apparatus, and recording medium storing bit stream

Provided are a video encoding/decoding method and apparatus, and a recording medium storing a bitstream. A video decoding method performed by a video decoding device according to the present invention comprises the steps of: decoding an indicator indicating whether partition data of a current block is derived from partition data of a corresponding block of the current block; obtaining partition data of the current block based on the decoded indicator; and partitioning the current block based on the obtained partitioning data. 提供一种视频编码/解码方法和设备以及存储比特流的记录介质。根据本发明的由视频解码设备执行的视频解码方法包括以下步骤：对指示当前块的分区数据是否从当前块的对应块的分区数据被推导的指示符进行解码；基于解码的指示符来获得当前块的分区数据；基于获得的分区数据对当前块进行分区。
