Abstract
A remote controllable device, apparatus or appliance such as a television is adapted to receive control signals from a universal remote control device addressed to a different appliance, i.e., when said appliance has not been selected, and informs the user that said appliance is not selected. Preferably the appliance displays information as to which other appliance has been selected, for example the TV could display on its screen the fact that it is receiving a remote control signal pertaining to a VCR by saying “VCR selected” when it receives a VCR control signal.
