1. A method of decoding an encoded image, comprising:
obtaining a layer identification (Layer ID) indicator from a first field of a header for a network abstraction layer (NAL) unit of the encoded image;
determining whether the Layer ID indicator is less than a start value;
in response to determining that the Layer ID indicator is not less than the start value, determining the Layer ID value based on the Layer ID indicator, an extension value provided in a second field of the header, and a number of bits used to represent the extension value; and
decoding the NAL unit based on the Layer ID value.
