The downloadable conditional access system (DCAS) is a complete end-to-end service protection system, which has all the scrambling, authorization control and management functions of the traditional conditional access system (CAS), and can support the use of traditional conditional access technology and DCAS at the same time The two types of set-top boxes of the technology can also realize the authorization control and management of the terminal through the two-way channel. Using DCAS technology, the digital TV set-top box only needs to download the client software of different DCAS systems to realize the switching and adaptation of different DCAS systems, so as to break the current situation of customizing set-top boxes for each cable network and realize the standardized scale production of set-top boxes. National sales of retail channels and cross-regional cross-network deployment have laid a solid foundation.

However, with the continuous advancement of the integration of the three networks and the goal of building the Next Generation Broadcasting Network (NGB), to realize the interconnection of the national cable TV network, it is still necessary to break through the limitations of the downloadable conditional access technology currently being implemented. Especially with the development of Internet TV, the smart TV-based operating system (TVOS) 1.0 was released in 2013. This system has the characteristics of high security, good openness, and strong integration. Therefore, in the process of transforming from traditional digital TV to smart TV, conditional access technology needs to simultaneously evolve from digital to smart. How to implement DCAS technology in TVOS is an urgent problem to be solved.
