1. A video decoding method, the method comprising:
decoding a first flag indicating whether information of virtual boundaries is signaled in a sequence parameter set (SPS) or not, the first flag being related to whether an in-loop filtering operation is disabled across the virtual boundaries,
decoding, based on the first flag, number information on a number of the virtual boundaries,
deriving, based on the first flag, a position of a virtual boundary by using position information on a position of a virtual boundary,
wherein, in response to the first flag indicating that the information of the virtual boundaries is signaled in SPS, the position information signaled in SPS,
wherein, in response to the first flag indicating that the information of the virtual boundaries is not signaled in SPS, the position information is signaled in PH, and
wherein the position information includes horizontal position information on a horizontal position of the virtual boundary and vertical position information on a vertical position of the virtual boundary.
