多媒体系统. 实现互操作性用模拟接口的推荐特性指南

[中文适用范围]： 该国际标准为多媒体模拟接口的特性的当前实践提供了指导，以实现不同制造商的设备之间的互操作性。它不是绩效标准。没有给出关于车辆使用的设备接口@以及广播和类似设备@的模拟视频接口的建议。数字信号的互连请参考 IEC 60958。 [外文原描述]： IEC 61938:2013 gives guidance on current practice for the characteristics of multimedia analogue interfaces to achieve interoperability between equipment from different manufacturers. It is not a performance standard. This second edition cancels and replaces the first edition published in 1996 and constitutes a technical revision. It includes the following significant technical changes: - the values in each table were chosen with respect to the state of the art and representative of best practice in industry; - plug-in power systems and soundcard power systems are added; - a new subclause 12.3 has been created: Interoperability of portable audio headphones/earphones and portable audio equipment; - a new Annex A describing pairing and screening of conductors is added; - a new Annex B describing phantom power variants for specialized applications is also added.
