标准范围

MPEG-21文件格式ISO/IEC 21000-9:20 05定义了多媒体传送和消费的开放框架,其中内容创建者和内容消费者都是焦点。MPEG-21的愿景是定义一个多媒体框架,以实现跨不同社区使用的各种网络和设备透明和增强地使用多媒体资源。ISO/IEC 21000-9:20 05旨在包含一个基本的MPEG-21 XML文档及其一些或所有辅助资源,可能在一个包中。它形成了一系列盒结构规范的一部分,并且使用来自ISO基本媒体文件格式ISO/IEC 14496-12(技术上与15444-12相同)的工具构建,特别是那些为静态元数据(未定时元数据)和MPEG-21集成文档处理提供统一结构方法的工具。

ISO/IEC 21000-9:2005, the MPEG-21 File Format, defines an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities.

ISO/IEC 21000-9:2005 is designed to contain a base MPEG-21 XML document with some or all of its ancillary resources, potentially in a single package. It forms part of a family of specifications which are box-structured, and is built using tools from the ISO Base Media File Format ISO/IEC 14496-12 (technically identical to 15444-12), specifically those that provide the unified structural approach to both static meta-data (untimed meta-data) and MPEG-21 integrated document handling.
