The present invention is intended to solve troubles caused by an AV system that is supposed to be operated on the basis of one-to-one relationship between a base station device and a monitor devise. When the AV system constituting one base station device and a plurality of monitor devices is used, the problem, which is caused by the each monitor device capable of controlling the base station device, may be encountered. The right of control is given to only one particular monitor device at a time among a plurality of monitor devices. The monitor device is set whether or not it will function as master as the right of control. When the monitor device requests the transmission/reception of a control command for controlling the base station device, a command sender/receiver middleware of this monitor device executes the transmission/reception of a control command in response to this request only when the monitor device is set to master. This novel configuration allows only the monitor device set to master to control the base station device.
