Abstract (en)

[origin: WO0042766A1] A remote control transmission unit (RCT) in accordance with the invention comprises a receiver (RER), a decision circuit (DC), and a transmitter (TR). The receiver (RER) receives input remote control commands (IRC) transmitted by a user-operable remote control unit (RCU). The transmitter (TR) transmits output remote control commands (ORC). The decision circuit (DC) determines whether the input remote control commands (IRC) belong to a predetermined group. The transmitter (TR) selectively re-transmits the input remote control commands (IRC) as output remote control commands (ORC) to a controllable apparatus (APP1) in dependence on whether the input remote control commands (IRC) belong to said predetermined group or not. Such a remote control transmission unit (RCT) is advantageously used in a system with a first controllable apparatus (APP1) with a certain function (for example, teletext) and a second controllable apparatus (APP2) which supplies an enhanced version of the certain function. The remote control transmission unit (RCT) is arranged in such a way that, on the one hand, a remote control receiver (RE1) of the first controllable apparatus (APP1) is able to receive the re-transmitted remote control commands (ORC), while, on the other hand, the input remote control commands (IRC) transmitted by the remote control unit (RCU) are shielded. The second controllable apparatus (APP2) receives all the input remote control commands (IRC).
