标准摘要
[中文适用范围]： 本文件定义了网络视频客户端与视频传输设备之间的通信过程。这一新的规范集使得能够使用来自不同制造商的设备接收器构建网络视频系统，这些系统使用通用且定义良好的接口。这些接口涵盖的功能包括媒体和成像配置、音频和视频的实时流、云台-俯仰-变焦（PTZ）控制以及分析。本文件中定义的管理和控制在接口被描述为web服务。附件F包含了所引入的网络服务的XML架构和Web服务描述语言（WSDL）定义。 [外文原描述]： IEC 62676-2-31:2019 defines procedures for communication between network video clients and video transmitter devices. 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. These interfaces cover functions such as media and imaging configuration, real-time streaming of audio and video, pan, tilt and zoom (PTZ) control as well as analytics. The management and control interfaces defined in this document are described as web services. Annex F contains XML schema and Web Service Description Language (WSDL) definitions for the introduced network services. This first edition, together with IEC 60839-11-31 and IEC 62676-2-32, cancels and replaces IEC 62676-2-3:2013. This edition includes the following significant technical changes with respect to IEC 62676-2-3:2013: a) addition of the Media2 service; b) additional methods for the imaging service; c) method duplicates from the device IO service have been removed; d) both the display and analytics device service are no more included.
