scope:

This Recommendation specifies the functional requirements of conditional access systems (CAS) deployed in digital addressable systems (DAS) for television broadcasting to enable factual subscriber-base reporting and to ensure protected delivery of content to authorised subscribers.

The objective of this Recommendation is to address two major concerns related to CAS namely, underreporting of subscriber numbers and content piracy, leading to revenue loss to broadcasters, content providers and the governments.

This Recommendation elaborates the various functional requirements of the CAS such as log requirements, reports requirements, database requirements, security requirements, service requirements, and more. Compliance with these requirements in CAS performance will address the concerns mentioned above.
