1. An encoder comprising:
circuitry; and
memory coupled to the circuitry, wherein
in operation, the circuitry:
encodes, for each of decoding units per temporal sub-layer, one or more hypothetical reference decoder (HRD) parameters into an HRD-related supplemental enhancement information (SEI) message, the one or more HRD parameters being one or more parameters for an HRD, the one or more parameters being related to a decoding unit, the HRD-related SEI message being an SEI message related to the HRD.
