Interesting Read about Nagra

Hi guys

Found this on another forum and quoting the whole post. Makes interesting read.

Found this it explains a few things

Have a read it may explain something to you.

Digital systems

Three versions of Nagravision are in common use for digital satellite television, known as Nagravision, Nagravision Cardmagedon, and Nagravision Aladin. Nagravision Cardmagedon and Aladin are often confused with each other. Nagravision Cardmagedon is however, a complicated combination of Nagravision Aladin and Mediaguard SECA 2 encryption.

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:

* StarHub TV (Singapore)
* Virgin Media (United Kingdom) (Nagravision 1)
* Dream Satellite TV (Philippines) (Nagravision 3)
* Polsat (Poland) (Nagravision 3)
* Digital+ (Spain) (Nagravision 3)
* TV Cabo (Portugal) (Nagravision 3)
* Premiere (Germany) (Nagravision 3)
* Digi TV (Romania) (Nagravision 2 & Nagravision 3)
* Bell TV (Canada) (Nagravision 3)
* Look Communications (Canada)
* Reliance BigTV (India)
* Dish Network (USA) (Transition to Nagravision 3 was completed on 6/18/09)
* UPC (Ireland) (Nagravision 1 being phased out, currently switching to Nagravision 3)
* UPC (Romania) (Nagravision 3)
* Telenet (Belgium) (Belgium) (Nagravision 2)
* Tivù Sat, Mediaset Premium and Pangea platform (Nagravision 3)

Initially all International channels including Pakistani channels were moved from N2 to N3, then Indian channels and in the third phase Adult channels have been moved. The rest of the channels were transferred to Nagra 3 on DishNetwork, on June 18, 2009.

Digital+ and Top Up TV are the only providers using Nagravision Cardmagedon (and also Nagravision Aladin) after its adoption in March 2005 and 2008 respectively.

The original Nagravision 1 is now almost obsolete after it was originally compromised in 1999, although Dream Satellite maintain relative security by changing keys several times throughout the day, causing great inconvenience to unauthorized viewers.

The Nagravision Aladin providers have been confronting the issue of satellite signal piracy and smart card piracy, since the system was publicly compromised in summer 2005. At first, security of the system was regained, with software revisions, manipulation of the Nagravision encryption algorithm, along with the phasing out of older cards, like the ROM101, ROM102, ROM103 in USA and ROM110,ROM120,ROM130 in Europe, in favour of the newer ROM142/ROM180.

Card hackers have, however, continued to compromise the encryption system, with continued software and key releases being made available to the public. Software emulation of the Nagravision system has been implemented in many Free-To-Air Satellite receivers, allowing unauthorised viewing to those who do not own an official card.[citation needed].
