摘　　要：通过比较实现CA系统的3个技术方案,引入DVB-CI公共接口概念并给出了CA系统中CI接口设计的框图,对公共接口协议作了简述,在此基础上完成CI接口的硬件设计和软件开发实现,简要介绍了对公共接口的扩展应用。The article introduces the concept of DVB-CI and provides its design architecture in CAS, by comparing throe technical schemes of CAS implementation. The CI protocol is discussed briefly, then the CI hardware design and the software development based on the protocol are completed. Finally, we give the extended applications of CI briefly.
