从IPTV面临的安全挑战入手,针对IPTV内容加密的数字版权管理(DRM)技术,结合工程实践,给出了局用IPTV的DRM体系架构,以及主要功能模块的设计,包括密钥生成服务器(KGS),认证授权服务器(LS),数据库MySQL Cluster设计等.可为DRM技术标准化,DRM系统工程实践提供有益的技术参考.%The Digital Rights Management (DRM) technology is a hot candidate for IPTV content encryption. For application, the architecture of DRM in office IPTV system is designed. Furthermore, the key technologies and main modules in proposed DRM are presented, including the Key Generation Server(KGS), authentication and authorization server(LS) , and database MySQL Cluster. The paper can be a reference for DRM standardization and IPTV engineering implementation.
