A decision element 122 determines whether or not a certain combination of device classes is operable as a composite device. In the case of the affirmative answer, a determination element 136 identifies the type of the composite device and specifies a user interface for operating the composite device. A data output element 132 then displays the specified user interface in a window on a monitor 170 at a specific timing. This arrangement effectively improves the operatability of the device control. ## Claims ### Claim 1 A device control apparatus that enables control of a source device, which is a transmitter of data,
