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.

Abstract: The present invention relates to a method and an apparatus for decoding an image, for decoding a bitstream including a plurality of layers. The image decoding method may comprise: a step of receiving and identifying dependency information indicating whether an upper layer is coded by the same coding method as a lower layer; and a step of recovering the image of the upper layer based on the identified dependency information. Thus, information indicating whether the information of the reference layer which the current layer refers to is encoded data or recovered value can be identified.
