1. A method of decoding an image, wherein the method is performed in an image decoding apparatus, the method comprising:
dividing, based on division information signaled through a bitstream, a picture including a current block into tiles; and
reconstructing the current block, the current block resulting from partitioning a maximum coding unit based on at least one of a quad-tree partition or a binary-tree partition,
wherein one of the tiles is divided into tile segments by at least one division boundary line in only one of a vertical direction or a horizontal direction independently of others of the tiles,
wherein each of the tile segments is composed of an integer number of maximum coding unit rows,
wherein each of the maximum coding unit rows includes a plurality of maximum coding units,
wherein the each of the tile segments has a rectangular shape,
wherein the quad-tree partition is performed based on a first partition flag indicating whether to perform the quad-tree partition,
wherein when a size of the coding block is greater than or equal to a pre-defined threshold size, the quad-tree partition only is performed,
wherein the pre-defined threshold size is 128×128, and
wherein the binary-tree partition is performed only when the quad-tree partition is no longer performed.
