信息技术.运动图像及其伴音信息的通用编码.第11部分:MPEG-2系统上的IPMP

[中文适用范围]： 本国际标准规定了 MPEG-2 系统上的 IPMP（知识产权管理和保护），包括： a) 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； b) IPMP描述符的语法和语义，其有利于IPMP保护信令； c) 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验证; ——IPMP 工具的连接/断开请求至所请求的 IPMP 工具; ——向 IPMP 工具通知 IPMP 工具的连接/断开; ——通用 IPMP 处理; ——与用户交互的 IPMP 工具； d) IPMP 信息往返于 IPMP 工具的语法和语义； e) 终端之间内容和 IPMP 工具的请求和传输的语法和语义； f) 用于描述 MPEG-2 终端/应用程序运行环境的 XML 语法和语义； g) 支持本文中的规范所需的注册机构列表。 本文档的结构如下。 第 1 条提供了对该文件的介绍。 第 4 条解释了条件接收框架和 MPEG-2 IPMP 框架之间的兼容性。 第 5 条概述了 IPMP 框架支持的流程，并确定了该流程中的不同规范要素。 第 6 条提供了第 5 条中标识的组件的规范。 第 7 条提供了消息传递架构和所有支持的消息的规范。 [外文原描述]： 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.
