4 currently used versions of Nagravision are in common use for digital satellite television, known as Nagravision, Nagravision Cardmagedon, Nagravision Aladin and Nagravision Merlin. Nagravision Cardmagedon and Aladin are often confused with each other and used under the term "Nagravision 2" which technically does not exist. Nagravision Cardmagedon is, however, a complicated combination of Nagravision Aladin and Mediaguard SECA 2 encryption. Nagravision Merlin is also known as Nagravision 3. The decryption unit is either integrated into a receiver, available as a
conditional-access module (CAM), or as one of many encryption schemes supported on a CAM
emulator. Nagravision has been adopted all over the world as a conditional access system, with providers: •
