1. A video decoding method performed by a video decoding apparatus, the method comprising:
parsing, from a bitstream, level information representing a level to which output layer sets conform;
obtaining, from the bitstream, constraint information for constraints to which the output layer sets conform; and
performing a decoding procedure for a current picture based on the level information and the constraint information,
wherein the constraint information is obtained through a general constraint information syntax,
wherein the level information and the general constraint information syntax are included in a profile tier level syntax of the bitstream, and
wherein the general constraint information syntax is present after the level information within the profile tier level syntax.
