1. A video decoding method performed by a video decoding apparatus, comprising:
parsing, from a bitstream, a flag representing whether information on constraints to which output layer sets conform is present in a general constraint information syntax, the flag being present in the general constraint information syntax;
parsing the information on the constraints from the general constraint information syntax based on the flag; and
decoding a current picture encoded based on the information on the constraints,
wherein the general constraint information syntax includes number information on the constraints and alignment information,
wherein the alignment information is present after the number information in the general constraint information syntax, and
wherein the alignment information is parsed last from the general constraint information syntax.
