Abstract
An image decoding method of decoding encoded data per unit included in units that are included in a picture is provided. The image decoding method obtains, from an encoded bitstream including the encoded data, a first flag indicating whether or not a removal time of the encoded data from a buffer for storing the encoded data is set per unit. The image decoding method further obtains, from the encoded bitstream, a second flag indicating whether an interval between removal times of the units is constant or arbitrary when the removal times are set per unit. The image decoding method removes the encoded data from the buffer per unit and at a constant or arbitrary interval according to the second flag, and decodes the removed encoded data.
