Conditional access systems (CAS) are used by content providers, such as pay-TV operators, to ensure only those subscriber devices which meet certain conditions can access the protected content.
Conditional access systems work by encrypting digital transport streams (the pay-TV content) and sending authorizations to decrypt the content separately via entitlement management messages (EMM)
Global CAS systems are underpinned by specific industry standards such as Moving Picture Experts Group (MPEG) and Digital Video Broadcasting (DVB), and the very important DVB Simulcrypt interface standard for digital television.
The rise of digital content and modes of distribution means content providers need to use a mixture of conditional access and digital rights management (DRM).
Conditional access systems work by requiring certain criteria to be met before granting a user access to the content. Here’s a closer look at how conditional access systems work. The broadcaster (for example, the pay-TV operator) encrypts their content and provides subscribers with the means to decrypt it via their set-top boxes (STB) aided by some CA-specific messages.
