<p>New pay TV systems, e.g. the Videocrypt system, make use of smart cards (5) which control the access to a respective decoder (6) for de-scrambling the TV signal. In order to be efficient in production, decoders have to be completely identical for the manufacturer. But each program-provider would prefer specifically customized decoders. For instance, in cable networks the cable operators will use different channel allocation depending from the respective site. Currently the only solution available is that the user or more often the installer will program the decoder. This operation is fastidious and consumes a lot of time. The inventive method offers a quick and flexible solution for personalizing intelligently a pay TV decoder (6) or respective devices. In each pay TV receiver decoder (6) with an access control based on a smart card (5) there are components which are able to read any smart card responding to a predefined format. The invention uses a dedicated smart card in order to perform automatically a channel programming.</p> |
