IMAGE DECODING METHOD AND APPARATUS USING SAME

摘要

The image decoding method for decoding a bitstream including a plurality of layers, according to the present invention, may comprise: a step of receiving information regarding a video parameter set including information regarding the dimension type for identifying the scalability of the plurality of layers and regarding the length of the dimension ID for identifying the layer to which the dimension type is applied; and a step of parsing the video parameter set in order to identify the information on the scalability contained in the bitstream. Thus, a method for identifying a scalability layer in a bitstream is provided.
