Abstract
The invention relates to a multimedia device comprising a remote control system for wirelessly controlling a multimedia appliance. In order to establish a connection between a remote control system and a multimedia appliance, the remote control system must identify itself to the multimedia appliance, by means of a hardware device, especially a SIM card. The individual user must also identify him/herself to the multimedia appliance, by means of a hardware device for detecting biometric data. The respective identification data is encoded by means of asymmetrical cryptography. During the initialization process between said two appliances, data encoded for the identification of the remote control system and each person is transmitted to the multimedia appliance and stored therein in an encoded manner. In order to establish a connection after the initialization, the corresponding data is asymmetrically encoded, in turn, from the remote control system to the multimedia appliance using another code, and is decoded in the multimedia appliance. The corresponding data stored in the multimedia appliance is also decoded and compared with the received decoded data.
