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

The invention provides a video encoding/decoding method and apparatus, and a recording medium storing a bitstream. Provided are a video encoding/decoding method and apparatus. A video decoding method performed by a video decoding apparatus according to the present invention may comprise the steps of: deriving an intra prediction mode of a current block; and performing intra prediction of the current block based on the intra prediction mode. The step of deriving the intra prediction mode may include a step of decoding an indicator as to whether the mode is the same as a set mode. 本公开提供了一种视频编码/解码方法和设备以及存储比特流的记录介质。提供了视频编码/解码方法和设备。根据本发明的由视频解码设备执行的视频解码方法可包括以下步骤：推导当前块的帧内预测模式；并基于帧内预测模式执行当前块的帧内预测。推导帧内预测模式的步骤可包括对关于所述模式是否与设定模式相同的指示符进行解码的步骤。
