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 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 the bitstream including split information for the current coding unit when a size of the current coding unit is greater than a predetermined size, wherein the split information indicates whether the current coding unit is split into four blocks smaller than the current coding unit; and
generating the 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 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 size, the split information for the current coding unit is not included in the bitstream,
wherein the predetermined size is equal to or greater than a minimum size allowable to a coding unit,
wherein size limit information indicating the predetermined size is used for a plurality of coding units included in the current picture unit, and 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,
wherein when the current coding unit is split into the four blocks smaller than the current coding unit, the split information is generated to indicate a split of the current coding unit, and
wherein the bitstream includes the information about the minimum size allowable to the coding unit and the size limit information.
