Claim 2:
3. A non-transitory computer-readable medium storing a computer program, wherein the computer program, when executed at a processor, implements a method for generating a bitstream, the method comprising:
determining a plurality of largest coding units of a predetermined first size in a current picture unit;
determining a current coding unit included in a current largest coding unit that is one of the plurality of largest coding units;
generating a bitstream including split information for the current coding unit when a size of the current coding unit is greater than a predetermined second size, wherein the split information indicates whether the current coding unit is split into four blocks smaller than the current coding unit; and
generating a bitstream including partition mode information for the current coding unit when the size of the current coding unit is equal to or less than the predetermined second size, 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 predetermined second size, the split information for the current coding unit is not included in the bitstream,
wherein the predetermined second size is equal to or greater than a minimum size allowable to the current coding unit,
wherein size limit information indicating the predetermined second size is used for a plurality of coding units included in the current picture unit, and information about the minimum size allowable to the current 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 current coding unit is split into the four blocks smaller than the current coding unit, independently from other coding units in the current largest coding unit, the split information is generated to indicate a split of the current coding unit.
