Addressability is the ability of a

devices) to control exactly where or to which devices the message is physically sent.

conditional access system (CAS), and allows the cable system to control and administer which cable products a customer may purchase and/or view.[1]

A typical cable communications system includes several basic components such as a

encrypted and having authorization codes attached thereto by a Scrambler
. The billing system or BSS typically manages products and services, customers and addressable equipment such as the converters and controllers. A customer's request for a certain service or product is normally forwarded to the BSS. The billing system or BSS sends instructions to the controller, which configures the converter in accordance with the instructions. The controller also communicates with the headend to receive the proper authorization information needed for the particular configuration. This information is sent to the converter. The converter also receives the signal and compares information on the signal to corresponding authorization from the controller. Based on the comparison, the customer's STB may or may not be able to descramble the signal and view the content or Television Program.

The Addressability system may be viewed as the interface between the billing system or BSS/OSS and the controller. Known Addressability systems receive information from the billing system and send it to the appropriate controller to enable the controller to properly configure the converter. A conventional Addressability system may include an Addressability server linked to the billing system. The Addressability server receives information from the billing system and passes it to controller processors, which forward the information to the appropriate controller. Known systems are hardware driven and the packaging of enabling information is integrated with the billing system. The billing system gathers data corresponding to the customer and request, then packages the data into a format for a particular type of controller. Different types of controllers include controllers manufactured by General Instrument (GI), Motorola, Jerrold, Scientific Atlanta,[3] Zenith, Tocom and Oak.
