<p>Disclosed are a method and apparatus for encoding and decoding an image using a progressive hierarchical switch. The present invention relates to technology for encoding and encoding a plurality of images of a hierarchical structure. A bit stream is progressively decoded from an arbitrary access point in case of two or more NAL unit types if an IRAP picture and a non-IRAP picture or only the IRAP pictures are in AU which is the arbitrary access point of the bit stream.</p> |
