1. A method of decoding video data, the method comprising:
determining that a value of a sequence parameter set (SPS) video parameter set identification (ID), within a bitstream including the video data, is equal to zero;
based on the determination that the value of the SPS video parameter set ID is equal to zero, determining that a SPS of the video data does not refer to a video parameter set (VPS) and that no VPS is referred to when decoding the video data referring to the SPS;
based on the determination that the value of the SPS video parameter set ID is equal to zero such that the SPS of the video data does not refer to the VPS and that no VPS is referred to when decoding the video data referring to the SPS, determining, without processing a syntax element, from the bitstream, that indicates whether the profile-tier-layer structure is present in the SPS, that a profile-tier-layer structure is present within the SPS; and
decoding the video data based on data of the profile-tier-layer structure included within the SPS.
