本标准定义了接口系统的电气和机械特性，该接口系统由通用通信信道和接口设备组成，用于在用于制作、后期制作和/或视觉和听觉信息传输的设备之间传输数据和数字控制信号。本标准中描述的通信信道和设备是整体设备接口的一部分，允许按要求互连可编程和非可编程控制及附属设备，以配置具有规定功能的操作系统。该标准还旨在允许利用给定的一组设备快速重新配置提供多个定义功能的系统。

This standard defines the electrical and mechanical characteristics of an interface system comprised of a general-purpose communication channel and interface devices used for the transfer of data and digital control signals between equipment utilized in the production, post-production, and/or transmission of visual and aural information. It is intended that the communication channel and device(s) described in this standard be part of an overall equipment interface, allowing interconnection of programmable and nonprogrammable control and accessory equipment as required to configure an operational system with a defined function. The standard is also intended to allow rapid reconfiguration of a system providing more than one defined function utilizing a given group of equipment.
