1. An encoding method comprising:
encoding one or more data groups; and
generating coded data, a first parameter set for the coded data, and a second parameter set, the coded data including one or more data units, the one or more data units each including a data unit header, wherein
the first parameter set includes one or more data group parameters corresponding to the one or more data groups, respectively,
the second parameter set includes a first parameter set index indicating the first parameter set corresponding to the second parameter set, and
the data unit header of a first data unit includes (i) a second parameter set index indicating the second parameter set corresponding to the first data unit and (ii) a value indicating a data group parameter corresponding to the first data unit among the one or more data group parameters stored in the first parameter set.
