ISO/IEC 13818-11:20 04规定了MPEG-2系统上的IPMP(知识产权管理和保护)。MPEG-2 IPMP提供灵活性、健壮性和互操作性，这允许在MPEG-2系统中安全地传递内容。MPEG-2 IPMP可以与专有的IPMP工具结合使用，这使得能够为不同的业务模型实现不同程度的安全性，同时保持互操作性。 ISO/IEC 13818-11:20 04规定: IPMP控制信息的语法和语义，包括工具列表、工具容器和权限容器；有助于IPMP保护信令的IPMP描述符的语法和语义；从公共基类IPMP_Data_BaseClass扩展的IPMP数据的语法和语义，以支持以下功能:IPMP工具到IPMP工具以及IPMP工具到终端通信的相互认证，由IPMP工具请求到所请求的IPMP工具的连接/断开，向IPMP工具通知IPMP工具的连接/断开，公共IPMP处理，IPMP工具到/来自用户交互；往返于IPMP工具的IPMP信息载体的语法和语义；用于在终端之间请求和传输内容和IPMP工具的语法和语义；用于描述MPEG-2终端/应用程序运行的环境的XML语法和语义；支持此处找到的规范所需的注册机构列表。

ISO/IEC 13818-11:2004 specifies IPMP (Intellectual Property Management and Protection) on the MPEG-2 system. MPEG-2 IPMP offers flexibility, robustness and interoperability, which allows the secure content delivery in the MPEG-2 system. MPEG-2 IPMP can be used in combination with proprietary IPMP tools, which enables the implementation to various degrees of security for different business models, while maintaining the interoperability. ISO/IEC 13818-11:2004 specifies:

• syntax and semantics for IPMP control information which includes tool list, tool container and rights container;
• syntax and semantics for IPMP descriptors, which facilitates IPMP protection signalling;
• syntax and semantics of IPMP data extending from the common base class IPMP_Data_BaseClass to support the following functionalities:
  • mutual authentication for IPMP tool to IPMP tool as well as IPMP tool to terminal communication,
  • the requesting by IPMP tools of the connection/disconnection to requested IPMP tools,
  • the notification to IPMP tools of the connection/disconnection of IPMP tools,
  • common IPMP processing,
  • IPMP tool to/from user interaction;
• syntax and semantics for IPMP information carriage to and from IPMP tools;
• syntax and semantics for the request and transfer of content and IPMP tools between terminals;
• XML syntax and semantics for the description of the environment in which the MPEG-2 terminal/application is operating;
• a list of registration authorities required for the support of the specifications found herein.
