Claim 6:
7. A decoding device of decoding network abstraction layer (NAL) unit information, the decoding device comprising:
a processor; and
a memory associated with the processor, wherein the processor is configured to:
receive a network abstraction layer unit header syntax structure having two bytes;
decode (i) a first 1-bit syntax element, (ii) a second 1-bit syntax element, and (iii) a 6-bit syntax element sequentially in a first byte of the network abstraction layer unit header syntax structure, wherein a value of the first 1-bit syntax element is equal to zero, a value of the second 1-bit syntax element is equal to zero, and the 6-bit syntax element specifies an identifier of a layer to which a Video Coding Layer (VCL) NAL unit belongs or an identifier of a layer to which a non-VCL NAL unit applies; and
decode (i) a 5-bit syntax element and (ii) a 3-bit syntax element sequentially in a second byte of the network abstraction layer unit header syntax structure, wherein the 5-bit syntax element specifies a NAL unit type, and the 3-bit syntax element specifies a temporal identifier for a NAL unit.
