Type The type of this atom; this field must be set to ‘rmda’.

Data reference atom Each reference movie atom must contain exactly one data reference atom. See “Data Reference Atoms” for more information.

Data rate atom A reference movie atom may contain an optional data rate atom. Only one data rate atom can be present. See “Data Rate Atom” for more information.

CPU speed atom A reference movie atom may contain an optional CPU speed atom. Only one CPU speed atom can be present. See “CPU Speed Atom” for more information.

Version check atom A reference movie atom may contain an optional version check atom. Multiple version check atoms can be present. See “Version Check Atom” for more information.
