  • Patent number: 6778225
    Abstract: In a method and arrangement for installing or updating a large number of television receivers in, e.g., hotels, one of the television receivers (1) is manually programmed. The data is then downloaded from the television receiver into a remote control unit (3) by modulating a conventional status LED (17) of the television receiver. In accordance with the invention, the status LED is of a type which emits visible light (171) as well as infrared light (172). The modulated infrared light beam (172) is detected by an infrared detector (34) of the remote control device and stored (35) therein. The data stored in the remote control unit is subsequently uploaded to other television receivers using the conventional infrared channel (33,15).
