Title
(EN) REMOTE CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE A DISTANCE
Abstract
(EN)
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).
(FR)
L'invention porte sur une unité de transmisison à commande à distance comprenant un récepteur (RER), un circuit de décision (DC) et un émetteur (TR). Le récepteur reçoit des commandes d'entrée par commande à distance (IRC) transmises par une unité de commande à distance (RCU) actionnée par un utilisateur. L'émetteur (TR) transmet des commandes de sortie par commande à distance (ORC). Le circuit de décision (DC) détermine si les commandes d'entrée (IRC) appartiennent à un groupe prédéterminé. L'émetteur (TR) retransmet sélectivement les commandes d'entrée (IRC) sous forme de commandes de sortie (ORC) à un appareil contrôlable (APP1) en fonction de l'appartenance ou non des commandes d'entrée (IRC) à un groupe prédéterminé. Ce type d'unité de transmission par commande à distance (RCT) est utilisé de manière avantageuse dans un système doté d'un premier appareil contrôlable (APP1) ayant une certaine fonction (par exemple, le télétexte) et un second appareil contrôlable (APP2) qui fournit une version améliorée de cette fonction. L'unité de transmission par commande à distance (RCT) est agencée de sorte que, d'un côté, un récepteur de commande à distance (RE1) du premier appareil contrôlable (APP1) puisse recevoir les commandes retransmises par commande à distance (ORC), tandis que, d'un autre côté, les commandes d'entrée (IRC) transmises par l'unité de commande à distance (RCU) soient protégées.
