    摘要： A decoding apparatus for an image decoding is configured to receive (S1810) image information including information on a tile (610, 620) and information on a slice, wherein the tile (610, 620) is a common rectangular region of a column of largest coding units (LCUs) and a row of largest coding units (LCUs) and the slice comprises an integer number of largest coding units (LCUs), derive (S1820) the tile (610, 620) and the slice in a current picture (300; 400; 500; 1110; 1210; 1410) based on the received image information, wherein the current picture (300; 400; 500; 1110; 1210; 1410) includes more than one tile (610, 620) and more than one slice, and perform decoding (51830) for the current picture (300; 400; 500; 1110; 1210; 1410) based on the more than one tile (610, 620) and the more than one slice.
    The following constraints are imposed:
    The largest coding units (LCUs) in the slice are ordered consecutively in tile scan order.
    In the tile scan order, largest coding units (LCUs) in each of the tiles (610, 620) in the slice are ordered in the raster scan order and the tiles (610, 620) in the slice are ordered in the raster scan order.
    And tile IDs specifying the tiles (610, 620) ordered in the slice are consecutive.
