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.
