Abstract: Disclosed is a video signal processing method and device that encodes or decodes a video signal. In particular, the video signal processing method may comprise the steps of: parsing a first syntax element indicating whether a merge mode is applied to a current block; when the merge mode is applied to the current block, determining whether to parse a second syntax element on the basis of a first predefined condition, wherein the second syntax element indicates whether a first mode or a second mode is applied to the current block; when the first mode and the second mode are not applied to the current block, determining whether to parse a third syntax element on the basis of a second predefined condition; and determining a mode applied to the current block on the basis of the second syntax element or the third syntax element.
