  • the remote control unit transmits remote control commands in a coded form to control several functions of the controllable apparatus.
  • the remote control commands may be grouped in clusters corresponding to a certain functionality of the controllable apparatus. For example, in a television receiver equipped with a teletext decoder, the teletext commands may form such a group of remote control commands.
  • controllable apparatuses comprise the same functionality, for example, a VCR and a television receiver both with a teletext decoder
  • the group of remote control commands for controlling this same functionality needs to have different codes to prevent undesirable interaction. If the controllable apparatuses use the same transmission standard and the same coding standard, an extra knob on the remote control unit enables that controllable apparatus to be selected for which the function should be controlled. If the standards used differ, several remote control units are required, one for each controllable apparatus.

  • the transmitter transmits output remote control commands.
  • the remote control transmission unit may further comprise a decoder which decodes the input remote control commands.
  • the decision circuit determines whether the input remote control commands belong to a predetermined group.
  • the transmitter selectively re-transmits the input remote control commands to the controllable apparatus in dependence on whether the input remote control commands belong to said predetermined group or not.

  • Such a remote control transmission unit is advantageously used in a system with a first controllable apparatus (for example, a television receiver with a teletext decoder) and a second controllable apparatus (for example, a teletext decoder supplying upgraded textual and graphical information to an input of the television receiver to be displayed instead of the teletext information of the teletext decoder).
  • the remote control transmission unit is arranged in such a way that, on the one hand, a remote control receiver of the first controllable apparatus is able to receive the re-transmitted remote control commands, while, on the other hand, the input remote control commands transmitted by the remote control unit are shielded.

Abstract

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.
