标准范围

ISO/IEC 23002-4:20 10基于ISO/IEC 23001-4中规定的解码器描述来定义MPEG视频工具库(VTL)的描述。该工具库定义了FU的规范，这些FU足以根据以下编码标准构建完整的解码解决方案:ISO/IEC 14496-2(MPEG-4简单配置文件)，以及ISO/IEC 14496-10(MPEG-4 AVC约束基线配置文件)。ISO/IEC 23001-4的目标是定义通用框架原则，并且ISO/IEC 23002-4:20 09定义MPEG VTL，其包括来自现有MPEG编码标准的相关工具(或FU)。每个FU以文本描述的形式定义。还描述了输入和输出行为的约定。可以使用任何软件或硬件语言和组件来设计符合ISO/IEC 23002-4:20 09的实现。FUs文本规范的参考软件采用RVC-CAL语言编写，其正式语法在ISO/IEC 23001-4中提供，并将在ISO/IEC 23002-4的修订1中定义。

ISO/IEC 23002-4:2010 defines the description of the MPEG video tool library (VTL) based on the decoder description specified in ISO/IEC 23001-4. This tool library defines the specification of FUs, which are sufficient to build complete decoding solutions according to the following coding standards:

• ISO/IEC 14496-2 (MPEG-4 Simple Profile), and
• ISO/IEC 14496-10 (MPEG-4 AVC Constrained Baseline Profile).

The objective of ISO/IEC 23001-4 is to define the general framework principles, and ISO/IEC 23002-4:2009 defines the MPEG VTL that includes relevant tools (or FUs) from the existing MPEG coding standards. Each FU is defined in the form of a textual description. The conventions for the input and output behavior are also described.Implementations compliant with ISO/IEC 23002-4:2009 can be designed using any software or hardware language and components. The reference software for the textual specification of FUs is written in RVC-CAL language of which a formal syntax is provided in ISO/IEC 23001-4, and which will be defined in Amendment 1 to ISO/IEC 23002-4.
