ISO/IEC 23004-3:20 07规定了组件模型，它是MPEG多媒体中间件的实现技术。此外，还指定了实例化以及与组件和服务交互所需的支持应用程序编程接口的接口。 ISO/IEC 23004-3规定了以下内容: 组件模型（什么构成组件）； 交易单位（M3W组件）； 加载单元（可执行组件）； 实例化单元（服务）； 标准接口: 接口之间的导航（rcIUnknown，rcIServiceGeneric）； 绑定（rcIServiceGeneric）； 访问公共属性（rcIServiceGeneric）；

ISO/IEC 23004-3:2007 specifies the component model which is the realization technology of the MPEG Multimedia Middleware. In addition, the interfaces of the support application programming interface needed for instantiation and interaction with components and services are specified. ISO/IEC 23004-3 specifies the following:

• component model (what constitutes a component);
• Unit of Trading (M3W component);
• Unit of Loading (executable component);
• Unit of Instantiation (Service);
• standard interfaces:
  • navigation between interfaces (rcIUnknown, rcIServiceGeneric);
  • binding (rcIServiceGeneric);
  • access to public attributes (rcIServiceGeneric);
