1. A method of decoding video data, the method comprising:
receiving a sequence parameter set;
parsing a first flag, in the sequence parameter set, wherein the first flag has a first value specifying that subpicture identifiers are explicitly signaled and a second value specifying that the subpicture identifiers are not explicitly signaled;
in a case that the first flag specifies that the subpicture identifiers are explicitly signaled, parsing a second flag, in the sequence parameter set, wherein the second flag has a first value specifying that the subpicture identifiers are signaled in the sequence parameter set and a second value specifying that the subpicture identifiers are not signaled in the sequence parameter set; and
in a case that the second flag specifies that the subpicture identifiers are signaled in the sequence parameter set, parsing a syntax element, in the sequence parameter set, specifying a subpicture identifier for each respective subpicture.
