Claim 15:
16. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors of a device for reconstructing a Network Abstraction Layer (NAL) unit for video decoding, cause the one or more processors to:
decode a first syntax element included in a NAL unit header;
determine, based on the first syntax element, a NAL unit class comprising one or more NAL unit types, the NAL unit class being among a plurality of NAL unit classes each associated with separate sets of NAL unit types;
decode a second syntax element included in the NAL unit header, the second syntax element being different from the first syntax element; and
based on the NAL unit class being a first NAL unit class, determine a NAL unit type from among the one or more NAL unit types using a combination of the NAL unit class and the second syntax element, wherein the second syntax element being configured for indexing within a set of NAL unit types belonging to the first NAL unit class;
based on the NAL unit class being a second NAL unit class, determine the NAL unit type solely from the first syntax element and using information extracted from the second syntax element as a temporal identifier (TID); and
reconstruct the NAL unit based on at least the determined NAL unit type.
