Claim:
1. A method of decoding multi-layer video data, the method comprising: obtaining, by one or more processor circuits, from a bitstream, a Network Abstraction Layer (NAL) unit header of a NAL unit of the multi-layer video data, the NAL unit header comprising a layer identifier syntax element, wherein the layer identifier syntax element comprises a plurality of bits capable of representing values from 0 to 63; based on a value of the layer identifier syntax element being equal to 63, determining, by the one or more processor circuits, that the NAL unit header contains one or more additional bytes, wherein when the value of the layer identifier syntax element in the NAL unit header of the NAL unit is not equal to 63, the NAL unit header does not contain the one or more additional bytes; determining, by the one or more processor circuits, based on the value of the layer identifier syntax element and the one or more additional bytes, a layer identifier of the NAL unit; and using, by the one or more processor circuits, data in the NAL unit to decode a portion of the multi-layer video data.
