Claim:
1. A decoding method of decoding encoded data per unit from among units included in a picture, the decoding method comprising: decoding, from a bitstream including the encoded data, a first flag indicating whether a removal time of the encoded data from a buffer is set per unit, the buffer storing the encoded data; decoding, from the bitstream, a second flag indicating whether an interval between removal times of the units is constant when the removal time is set per unit; removing the encoded data from the buffer per unit and at the interval according to the second flag; and decoding the removed encoded data, wherein the first flag is decoded from video usability information of the bitstream, the video usability information being assigned to at least one picture, the second flag is decoded from control information of the bitstream, the control information being provided per picture, and the control information includes common-interval information when the second flag indicates that the interval is constant, the common-interval information being distinct from the second flag and indicating a constant time interval between removal times of any two consecutive units.
