标准摘要
[中文适用范围]： 本部分IEC 61603提供了测量和规定宽带音频红外传输系统特性的方法，这些特性未被本标准的第1部分所涵盖（另见3.1）。它允许描述以不同经济方式使用可用带宽的系统，以便得出有关干扰和兼容性的结论。还涵盖了接口（匹配）值和其他系统特性。本部分IEC 61603取代了IEC 60764的第1章，该章仅涵盖模拟音频信号的两个载波频率，且不涵盖数字音频。 [外文原描述]： Gives methods for measuring and specifying those characteristics of wide band audio IR transmission systems not covered by part 1 of this standard. This consolidated version consists of the first edition (1997) and its amendment 1 (2004). Therefore, no need to order amendment in addition to this publication.
