Most countries have implemented Digital Addressable Systems (DAS) for distribution platforms such as Cable TV, Direct to Home (DTH), Internet Protocol Television (IPTV), and Headend In The Sky (HITS). DAS enables subscribers to have a choice and option to select their channels and packages. Conditional Access System (CAS) and Subscriber Management System (SMS) are integral parts of a DAS environment. While CAS is responsible for encrypting the content and its delivery in a secure and encrypted manner only to authorised subscribers, SMS handles the subscriber management functions. The quality of service depends on the CAS and SMS systems deployed by the Distribution Platform Owner (DPO). Since the content providers and broadcasters have no control over the CAS and SMS, as these are deployed at the DPO end, they often complain about the loss of revenue due to various malpractices, such as under-reporting of subscriber-base, distribution of channels to unauthorised users, and content piracy. Therefore, it is necessary to frame benchmarks for the CAS systems, prescribing technical specifications focusing on functional requirements to ensure factual reporting of subscriber-base and protected delivery of content to authorised subscribers. Creating a framework that prevents the deployment of sub-standard CAS will bring preventive control from potential threats and revenue losses arising due to the vulnerability of such systems, bring economic efficiency, improve quality of service, and improve the end-consumer experience. The objective of the [draft new] 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 [draft new] Recommendation elaborates the various functional requirements of the CAS such as log requirements, reports requirements, database requirements, security requirements, service requirements, and more. Compliance to these requirements in CAS performance will address the concerns mentioned above.
