Conditional Access Systems (CAS)

In order to protect the content and rights, digital TV operators turn to the technology known as conditional access or CA. Conditional access, as the name itself suggests, provides the service of controlling the access to digital television to people who are or are not subscribers. Their end goal is simple and clear – encrypting the channel signal and decrypting it only for the viewers who meet the required conditions. Besides the most common use by digital TV operators, conditional access can also be applied to digital radio and data broadcasts, non-broadcast information and interactive services. The equipment and software required for the system is supplied by the CAS provider, so that the broadcasters can incorporate it in their own equipment.


Every CA system is made up of the following fundamental components: a Subscriber Management System, a Subscriber Authorization System, a security module and a set-top box.

Even though securing the content is of outmost importance to pay TV operators, the development and maintenance of a conditional access system can be extremely time consuming and ineffective. That is why operators entrust the safety of their content to companies specializing in pay TV protection technology.
