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 2):
A video decoding apparatus, comprising:\n a decoder configured to receive a bitstream comprising a network abstraction layer (NAL) unit including information on a current picture, to obtain NAL unit type information from a NAL unit header of the NAL unit, to derive a NAL unit type for the current picture based on the NAL unit type information, and to decode the current picture based on the NAL unit type; and a memory configured to store the decoded current picture, 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.
