CAS system is one of the most important support system for digital television development. The selected and receive-rebroadcasted program has already been commonly accepted in China and a lot of cities and areas have launched the fee television service of analog channels, while compared with the analog television, the digital television had a big enhancement in program quality, as well as in program contents. Using mechanism of CAS system to introducing paid program would be beneficial for harmonious development of all parties, as well as for forming the own program system themselves,thus multifunctional services and value-added services would be developed to open up new economic growth point of broadcast television, and to lay economic foundation for positive cycle development of television industry.
CAS system is a technical support system of digital TV charging. CAS means digital-scrambling (or digital-encrypting) the digital TV programs to establish effective charging system, and to protect the interests of program providers and TV station. The commercialization achievements of European digital TV prove that CAS system is an important element for pushing digital TV toward market success.
