Abstract
A method for decoding a first bitstream in which each of pictures has been encoded with being split into a plurality of tiles, each tile comprised of one or more coding tree units, the method comprises receiving the first bitstream which includes tile split information and area information, generating a second bitstream to be decoded, by extracting, from the first bitstream, only encoded data corresponding to the area defined by the area information which is included in the header of the first bitstream, and modifying syntax elements in the first bitstream using the reference position, and the width and the height from the reference position included in the area information, and outputting the second bitstream to thereby decode the extracted encoded data.
