标准范围

ISO/IEC 23001-1:20 06为编码XML文档提供了一组标准化的通用技术。它通过提供传输和压缩XML文档的通用方法来解决广泛的应用和需求。ISO/IEC 23001-1:20 06提供了一个规范，该规范给出了用于高效传输和存储的XML文档的准备规则，并且使得能够开发ISO/IEC 23001-1终端来接收、解码和组装可能被分区和压缩的XML文档。用于XML的二进制MPEG格式依赖于编码器和解码器之间的模式知识，以便达到高压缩效率，同时提供用于确保传输和处理灵活性的分段机制。ISO/IEC 23001-1:20 06还定义了编译和传输模式知识信息的装置，以使得能够在接收端处解码压缩的XML文档而无需先验模式知识。用于XML的二进制MPEG格式在四个主要部分中描述:系统架构介绍了符合ISO/IEC 23001-1的终端的架构和ISO/IEC 23001-1解码器的一般特性，例如解码器行为。二进制格式指定结构元素的二进制语法和相关联的语义。特别地，本节描述二进制访问单元的结构。二进制片段更新有效载荷指定有效载荷内容的二进制语法和相关语义。特别地，本节描述了使用有限状态自动机解码器的复杂类型内容的解码过程。高级优化解码器描述了使用高级优化解码器解码简单类型的XML文档的机制。如分别在ISO/IEC 15938-1(MPEG-7系统)和21000-16(MPEG-21二进制格式)中规定的，本说明书中描述的XML的二进制格式可用于编码MPEG-7和MPEG-21描述。

ISO/IEC 23001-1:2006 provides a standardized set of generic technologies for encoding XML documents. It addresses a broad spectrum of applications and requirements by providing generic methods for transmitting and compressing XML documents.

ISO/IEC 23001-1:2006 provides a specification which gives rules for the preparation of XML documents for efficient transport and storage, and enables the development of ISO/IEC 23001-1 terminals to receive, decode and assemble possibly partitioned and compressed XML documents.

The binary MPEG format for XML relies on schema knowledge between encoder and decoder in order to reach high compression efficiency, while providing fragmentation mechanisms for ensuring transmission and processing flexibility. ISO/IEC 23001-1:2006 also defines means to compile and transmit schema knowledge information to enable the decoding of compressed XML documents without a priori schema knowledge at the receiving terminal.

The binary MPEG format for XML is described in four main sections:

• System Architecture presents the architecture of an ISO/IEC 23001-1-compliant terminal and general characteristics of an ISO/IEC 23001-1 decoder, such as decoder behaviour.
• Binary Format specifies binary syntax and associated semantics of the structural elements. In particular, this section describes the structure of a binary access unit.
• Binary Fragment Update Payload specifies binary syntax and associated semantics of the payload content. In particular, this section describes the decoding process of complex Type content using finite state automaton decoders.
• Advanced Optimized Decoders describes the mechanisms for decoding simple types of an XML document using advanced optimised decoders.
