Card sharing has established itself as popular method of pirate decryption.Much of the development of card sharing hardware and software has taken place in Europe, where national boundaries mean that home users are able to receive satellite television signals from many countries but are unable to legally subscribe to them due to licensing restrictions on broadcasters.
Conditional Access Module Various types of CAM. A conditional access module (CAM) is an electronic device, usually incorporating a slot for a smart card, which equips an integrated digital television or set-top box with the appropriate hardware facility to view conditional access content that has been encrypted using a conditional access system.

A video management system, also known as video management software plus a video management server, is a component of a security camera system that in general: Collects video from cameras and other sources; Records / stores that video to a storage device; Provides an interface to both view the live video, and access recorded video
This module, in turn, then accepts the pay-to-view subscriber card, which contains the access keys and permissions. The host (TV or set-top box) is responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CA descrambling. The Common Interface allows them to communicate with each other.
Because an IP Video server uses IP protocols, it can stream video over any IP-compatible network, including via a modem for access over a phone or ISDN connection. With the use of a video server attached to an analog camera, the video from an existing surveillance system can be converted and networked into a new IP surveillance system.
Otherwise the decoder seeds the card's PRNG with a seed transmitted with the video signal to generate the correct sequence of cut points. The system also included a cryptographic element called the Fiat Shamir Zero Knowledge Test. This element was a routine in the smartcard that would prove to the decoder that the card was indeed a genuine card.
A video card or graphics card is a component of a computer which is designed to convert a logical representation of an image stored in memory to a signal that can be used as input for a display medium, most often a monitor utilising a variety of display standards. Typically, it also provides functionality to manipulate the logical image in memory.
MediaGuard is a conditional access system for digital television developed by SECA (Société Européenne de Contrôle d'Accès; renamed to Canal+ Technologies SA) (CEO François Carayol), a subsidiary of Canal+ Group, sold to Thomson (CEO Thierry Breton).
