Abstract: An interface adapter device consistent with certain embodiments has a first electrical connector adapted to connect to a conditional access service card to receive encrypted television signals therefrom. A second electrical connector is adapted to connect to a television receiver device in order to provide the encrypted television signals to the television receiver device. An interface circuit receives the encrypted television signals from the first electrical connector and adapts the signals for transmission to a television receiver device over the second electrical connector. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
