Abstract: Circuity for executing operations is provided. The operations obtain pieces of coded data that is included in a bitstream and generated by coding tiles. The pieces of coded data are decoded to generate image data of the tiles. When the pieces of coded data are obtained, tile boundary independence information is further obtained, which indicates whether each of boundaries between the tiles is one of a first boundary and a second boundary. When the pieces of coded data are decoded, image data of a first tile is generated by decoding a first code string included in first coded data with reference to decoding information of an already-decoded tile when the tile boundary independence information indicates the first boundary, and by decoding the first code string without referring to the decoding information of the already-decoded tile when the tile boundary independence information indicates the second boundary.
