Abstract:
The present invention includes an image information decoding method which comprises: a step of receiving a bitstream that includes a network abstraction layer (NAL) unit including information related to an encoded image; and a step of parsing an NAL unit header of the NAL unit. The NAL unit header includes layer information including reserved_one_5bits for identifying an extended layer in an extended bitstream and temporal_id for identifying a temporal layer of a bitstream. The reserved_one_5bits of the layer information is received prior to the temporal_id of the layer information. Thus, a method for describing scalability information in a hierarchical bitstream is provided.

Claim (Index 10):
A non-transitory decoder-readable storage medium storing a bitstream comprising a NAL unit generated by determining a network abstraction layer (NAL) unit type of a current picture, by deriving NAL unit type information based on the determined NAL unit type, by configuring a NAL unit header including the NAL unit type information, by generating the NAL unit including information on the current picture based on the NAL unit header, wherein the NAL unit type for the current picture is one of NAL unit types including a clean random access (CRA) type to specify a CRA picture, wherein the CRA picture is a random access point picture and the CRA picture has a uniform NAL unit type regardless of a type of a leading picture associated with the CRA picture, wherein an output order of the leading picture is prior to an output order of the CRA picture.
