DEVELOPMENT of ADVANCED CONDITIONAL ACCESS SYSTEMS in the FACE of ACCELERATING MARKET REQUIREMENTS

摘要

The evolution of the multi-channel payTV industry and its popular deployment has heightened the demand for elaborate capabilities, compelling features, and breathless delivery times. Conditional Access (CA), once a basic 'protecting the pipe' security mechanism, has come into its own as a primary component of the payTV solution, enabling diverse business models and services. CA's high adaptability accommodates customization for specific broadcaster, country, or market needs while supporting add-on services and applications. The increasing functional demands have driven CA's progress into modular, robust, and easy to use systems, scalable from modest to multi-million subscribers in size. The demands for quick delivery have prompted the creation of an adaptable 'off-the-shelf CA system that can be delivered within three months and later upgraded with add-on capabilities. These customer-driven requirements have been met by employing advanced software engineering methodologies and tools, coupled with rigorous component and system procedures. The end product, representing hundreds of person-years of work, is the basis for modern multichannel payTV solutions being deployed around the world, constituting close to 50% of the Digital TV market.
