Nagravision

Nagravision is a company that develops encryption systems for cable and satellite television. The company is of the Kudelski Group. Nagravision is also the name of a series of encryption systems. Three versions of Nagravision are in common use for digital satellite television, known as Nagravision, Nagravision Cardmagedon, and Nagravision Aladin.

Nagravision is generally used for satellite companies that broadcast fee based television programming. Broadcasts are encoded, so that non paying customers can not view programming. Encrypted programming is received by the customer, and the receiver on the customer premises has integrated decryption. The decryption unit is called a CAM (Conditional Access Modulator).

Nagravision conditional access systems are popular throughout the world and used by many top providers including Dish Network and Bell ExpressVu.
