BITSTREAM COMPRISING MULTI LAYERS DECODING METHOD AND APPARATUS USING THE SAME

摘要

PURPOSE: A decoding method of the bitstream capable of supporting a plurality of layers and a device using the same are provided to express the scalability information of various kinds of bitstream. CONSTITUTION: A parsing unit receives the information about the video parameter set including the information about a plurality of layers (501). The parsing unit parses the video parameter set, thereby understanding the information of the layer included in the bitstream (502). The information about the layers includes the maximum number of size information about various kinds of pictures included in the encoded video sequence. The information about the layers includes the index information about the set of frame size applied to the predetermined layer. [Reference numerals] (501) Receive information about the video parameter set including the information about a plurality of layer; (502) Understand the information of the layer by parsing the video parameter set
