| Abstract: | In this paper, the authors discuss Software-Hardware Detachable Technology in STB on its key points: CA soft architecture and relationships of the application interfaces, and then propose a universal CA software architecture based on DVB-C. The architecture can make the development of the CA system and that of IRD independently, so we have solved the key issue in Software-Hardware Detachable Technology for STB successfully. |
