Image encoding procedure, image decoding procedure, image encoding device, image decoding device, and image encoding / decoding device

摘要

An image encoding method of coding one or more units that are included in a picture, including: generating a first flag indicating whether or not a removal time of encoded data by a hypothetical decoder from a buffer for storing the encoded data is set per unit (S221); generating a second flag indicating whether an interval between removal times of the units is constant or arbitrary when the removal time is set per unit (S222); and generating an encoded bitstream including the encoded data, the first flag, and the second flag (S223).
