Abstract

Es wird eine Empfangsvorrichtung einer Fernbedienung vorgeschlagen. Sie umfaßt einen Decoder (32), der ein Codewort (C) empfängt und einen Speicher (30) enthält, in dem zumindest ein erster Algorithmus (F1, FN) und ein zweiter Algorithmus (FU) fest hinterlegt sind, wobei das Codewort (C) in Abhängigkeit von in einem Sender (S1, SN, SU) hinterlegten Senderalgorithmus (FS) erzeugt ist. Sie zeichnet sich dadurch aus, daß das Codewort (C) dann als zulässig erkannt ist, wenn ein Prüfalgorithmus (34) unter Verwendung zumindest des ersten Algorithmus (F1, FN) und/oder des zweiten Algorithmus (FU) eine Übereinstimmung eines dieser beiden Algorithmen (F1, FN, FU) mit dem Senderalgorithmus (FS) erkennt.

A remote control receiving device is proposed. It comprises a decoder (32) which receives a code word (C) and contains a memory (30) in which at least a first algorithm (F1, FN) and a second algorithm (FU) are permanently stored, the code word (C ) is generated as a function of the transmitter algorithm (FS) stored in a transmitter (S1, SN, SU). It is characterized in that the code word (C) is recognized as permissible when a test algorithm (34) using at least the first algorithm (F1, FN) and / or the second algorithm (FU) matches one of these two algorithms (F1, FN, FU) with the transmitter algorithm (FS).
