标准摘要
[中文适用范围]： IEC 62676 的第 2-3 部分定义了网络视频客户端和基于 Web 服务的视频传输设备之间的通信程序。这套新规范使得使用来自不同制造商的设备和接收器使用通用且定义明确的接口构建网络视频系统成为可能。这些接口涵盖设备管理@实时音频和视频流@事件处理@平移@倾斜和缩放（PTZ）控制@视频分析以及控制@录像搜索和重放等功能。该标准中定义的管理和控制接口被描述为Web服务。该国际标准还包含针对引入的网络视频服务的完整 XML 模式和 Web 服务描述语言 (WSDL) 定义。为了提供完整的即插即用互操作性，该标准定义了设备发现过程。标准中的设备发现机制基于带有扩展的 WS-Discovery 规范。引入这些扩展是为了满足特定的网络视频发现需求。该标准不仅限于发现@配置和控制功能@，而是使用适当的IETF标准分析定义了IP网络中媒体和元数据流的精确格式。此外，还引入了适当的协议扩展，以使网络视频制造商能够为其客户和集成商提供完全标准化的网络视频传输解决方案。支持符合本标准要求并借助Web服务的视频传输设备根据本部分的规范被声明为兼容IEC 62676-2 Web服务互操作性。 [外文原描述]： IEC 62676-2-3:2013 defines procedures for communication between network video clients and video transmitter devices based on Web Services. This new set of specifications makes it possible to build network video systems with devices and receivers from different manufacturers using common and well defined interfaces. The management and control interfaces defined in this standard are described as Web services. This international standard also contains full XML schema and Web Service Description Language (WSDL) definitions for the introduced network video services. Furthermore, appropriate protocol extensions have been introduced in order to make it possible for network video manufacturers to offer a fully standardized network video transfer solution to its customers and integrators. A video transmission device supporting compliance to the requirements of this standard with the help of Web services according to the specification of this part is declared as compatible to IEC 62676-2-1 Web service Interoperability.
