ISO/IEC 15938系列运行并生成符合要求的比特流。本文档提供了以一致方式运行的特定实现。注1符合ISO/IEC 15938系列的其他实现也是可能的，这些实现不一定使用参考软件的算法或编程技术。本文档中包含的软件称为实验模型（XM），分为五类:a)用于MPEG-7(BiM)的二进制格式。该软件将基于DDL（XML）的描述转换为二进制格式，反之亦然，如第5条所述。b)DDL解析器和DDL验证解析器。第6条规定了该软件模块的组件。c)视觉描述符。该软件从相关的（视觉）媒体内容创建标准视觉描述，如第7条所述。注2用于提取描述符的技术信息丰富，这些提取工具的质量和复杂性尚未优化。d)音频描述符。该软件从相关联的（音频）媒体内容创建标准描述，如第8条所述。注3用于提取描述符的技术信息丰富，这些提取工具的质量和复杂性尚未优化。e)多媒体描述方案。该软件模块提供如第9条所规定的多媒体描述方案的标准描述。
The ISO/IEC 15938 series operates on and generates conformant bitstreams. This document provides a specific implementation that behaves in a conformant manner.
NOTE 1 Other implementations that conform to the ISO/IEC 15938 series are possible, which do not necessarily use the algorithms or the programming techniques of the reference software.
The software contained in this document is known as eXperimentation Model (XM) and is divided into five categories:
a) Binary format for MPEG-7 (BiM). This software converts DDL (XML) based descriptions to binary format and vice versa as explained in Clause 5.
b) DDL parser and DDL validation parser. The components of this software module are specified in Clause 6.
c) Visual descriptors. This software creates standard visual descriptions from associated (visual) media content as explained in Clause 7.
NOTE 2 The techniques used for extracting descriptors are informative, and the quality and complexity of these extraction tools has not been optimized.
d) Audio descriptors. This software creates standard descriptions from associated (audio) media content as explained in Clause 8.
NOTE 3 The techniques used for extracting descriptors are informative, and the quality and complexity of these extraction tools has not been optimized.
e) Multimedia description schemes. This software modules provide standard descriptions of multimedia description schemes as specified in Clause 9.
