In an apparatus ( 200 ) arranged to control a home electronics system, the apparatus being managed independently of a user, the apparatus includes a data processing unit (CPU ( 204 ), Program ROM ( 208 ) and RAM ( 210 )), a first communications port ( 202 ) operable to receive a command, a second communications port ( 216 ) operable to receive a signal indicating an operative component in the system, and a third communications port ( 218 ) operable to output a substitute command to a component in the system. On receiving a command, the data processing unit may produce at least one substitute command in dependence on the operative component, this substitute command then being communicated to a component in the system. |
