1. An apparatus for decoding a video encoded based on a largest coding unit, the apparatus comprising:
a largest coding unit determiner configured to determine a plurality of largest coding units in a current picture unit; and
a decoder configured to decode the plurality of largest coding units,
wherein the decoder is further configured to:
obtain, from a bitstream, information about a minimum size allowable to a coding unit and size limit information;
determine a current coding unit included in a current largest coding unit that is one of the plurality of largest coding units;
obtain, from the bitstream, split information for the current coding unit when a size of the current coding unit is greater than a size acquired using the size limit information, wherein the split information indicates whether the current coding unit is split into four blocks smaller than the current coding unit; and
obtain, from the bitstream, partition mode information for the current coding unit when the size of the current coding unit is equal to or less than the size acquired using the size limit information, wherein the partition mode information indicates whether the current coding unit is split into two blocks smaller than the current coding unit,
wherein when the size of the current coding unit is equal to or less than the size acquired using the size limit information, the split information for the current coding unit is not obtained from the bitstream,
wherein the size acquired using the size limit information is equal to or greater than the minimum size allowable to the coding unit,
wherein the size limit information is used for a plurality of coding units included in the current picture unit, and the information about the minimum size allowable to the coding unit is used for a plurality of coding units included in a current sequence unit including the current picture unit, and
wherein when the split information indicates a split, the current coding unit is split into the four blocks smaller than the current coding unit.
