ABSTRACT:
A communication IC (11a) in an AV controller (1) periodically notifies plural slave apparatuses (e.g., a CD player (3), a radio (5), and an amplifier (7)) of a system state command containing a system state in which states of all the plural slave apparatuses are managed in a lump. CPUs (13ato13d) of the slave apparatuses determine whether or not the current apparatus state of the corresponding slave apparatus coincides with the system state in the system state command from the AV controller. If the current own apparatus state does not coincide with the system state in the system state command, the current own apparatus state is made coincident with the system state command.
