Abstract
EP 11593 A UPAB: 19930902 The table-top subunit has an alphanumeric keyboard interacting with a t.v. receiver, e.g. t.v. text-display systems. The hand-held subunit has a keyboard suitable for controlling the receiver's basic functions as in a conventional remote control. the hand-held subunit contains a battery charged from a mains supply circuit located in the table top subunit. The table-top subunit is connected to the t.v. receiver by cable. The hand-held subunit contains a transmitter that sends control signals via free-space to the t.v. receiver. When the hand-held subunit is plugged into the table-top subunit the signals from its keyboard are switched over from the free-space transmitter to the table-top subunit's cable, i.e. signals from the hand-held subunit's keyboard travel via the table-top subunit's cable to the receiver.
