Abstract: A remote control comprises object keys and a selector for linking preset IR or RF code sets to the object keys. The remote control comprises: —a selector for the selection of an IR or RF preset code set by a user, —an activator for the activation of one or more links between an element of said preset IR or RF code set and an object key by the user after the selection, —a selector for the subsequent selection of a further preset code set by the user and —repeat means for repeating the steps a and b for the further preset code set until all object keys have been linked or the user terminates the process. This allows the user to combine more than one preset code set into a single code set.

Abstract: In an arrangement including a remote control device and at least a first electronic device, the remote control device includes a first memory for storing a set of code data for controlling a further electronic device, the first memory being connected to an input of a signal generator for supplying the code data to the input, the signal generator generating, on the basis of the code data, control signals for controlling the further electronic device, and transmitting these control signals to the further electronic device. The first electronic device includes a data input for receiving data from the remote control device, and the remote control device includes a code data output unit connected to the first memory. The code data output unit has a further input for receiving an upload signal and reads, under control of the upload signal, at least a subset of the set of code data from the first memory.

Abstract: In a method of operating a remote control system and in such a system comprising an RF transmission and receiving system and an IR transmission device the sub-carrier information of the IR signal is transmitted in the RF signal in a signal separate from the envelope information of the IR signal which is contained in a envelope signal.

Abstract: A method of and a system for upgrading a universal remote control with a command code of an electronic appliance are provided. The command code is downloaded from an internet server into a personal computer or set-top box, which is coupled to an infrared transmitter. The universal remote control is placed in front of the infrared transmitter and the command code is transferred to the universal remote control, for example in response to the user indicating a key, shown in a displayed picture of a control panel of the electronic appliance and associated with said command code.

Abstract: The invention relates to a system including an apparatus and a plurality of remote controls. Each remote control is equipped with a detector for detecting infrared signals from the other remote controls. The remote controls are capable of controlling the transmission of messages in dependence on a detection of signals from the other remote controls. In this way, collision between signals from different remote controls is prevented.
