A method and arrangement for installing or updating a large number of television receivers in e.g. hotels is disclosed. One of the receivers (1) is manually programmed. The data is then downloaded from said receiver into a remote control unit (3) by modulating the conventional status LED (17) of the 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 receivers using the conventional infrared channel (33,15).
