信息技术.多媒体框架(MPEG-21).第8部分:参考软件

[中文适用范围]： 本国际标准描述了实现 ISO/IEC 21000 其他部分规范性条款的参考软件。所提供的信息适用于确定 ISO/IEC 21000 各部分可用的参考软件模块、理解可用参考软件模块的功能以及利用可用的参考软件模块。除了参考软件外，还描述了利用参考软件的可用（集成）实用软件。这些实用软件有助于理解如何利用参考软件，并提供对 ISO/IEC 21000 适用部分（例如 ISO/IEC 21000 其他部分的说明性条款）的进一步见解。 [外文原描述]： ISO/IEC 21000-8:2008 describes reference software implementing the normative clauses of the other parts of ISO/IEC 21000. The information provided is applicable for determining the reference software modules available for parts of ISO/IEC 21000, understanding the functionality of the available reference software modules, and utilizing the available reference software modules. In addition to the reference software, available (integrated) utility software that utilizes the reference software is also described. This utility software can assist in understanding how to utilize the reference software, as well as providing further insight into the applicable parts of ISO/IEC 21000, e.g. informative clauses of the other parts of ISO/IEC 21000. ISO/IEC 21000-8:2008 specifies reference software for: — ISO/IEC 21000-2:2005; — ISO/IEC 21000-3:2003; — ISO/IEC 21000-3:2003/Amd.1:2007; — ISO/IEC 21000-4:2006, ISO/IEC 21000-4:2006/Amd.1:2007; — ISO/IEC 21000-5:2004, ISO/IEC 21000-5:2004/Amd.1:2007, ISO/IEC 21000-5:2004/Amd.2:2007; — ISO/IEC 21000-6:2004; — ISO/IEC 21000-7:2007; — ISO/IEC 21000-9:2005; — ISO/IEC 21000-10:2006, ISO/IEC 21000-10:2006/Amd.1:2006; — ISO/IEC 21000-12:2005; — ISO/IEC 21000-14:2007; — ISO/IEC 21000-15:2006; — ISO/IEC 21000-16:2005; and — ISO/IEC 21000-17:2006. ISO/IEC 21000-8:2008 also specifies (integrated) utility software for ISO/IEC 21000-2:2005, ISO/IEC 21000-3:2003, ISO/IEC 21000-5:2004, ISO/IEC 21000-5:2004/Amd.1:2007, ISO/IEC 21000-6:2004, ISO/IEC 21000-7:2007, and ISO/IEC 21000-10:2006/Amd.1:2006.
