Annotation of standard text IEC 62676-2-31-ed.1.0 :
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. lIEC 62676-2-3:2019 definit les procedures de communication entre les clients video en reseau et les dispositifs de transmission video. Ce nouvel ensemble de specifications permet de concevoir des systemes video en reseau avec des dispositifs et des recepteurs de differents fabricants utilisant des interfaces communes et bien definies. Ces interfaces couvrent des fonctions telles que la configuration multimedia et dimagerie, la transmission en continu en temps reel de contenu audio et video, le controle panoramique, inclinaison et zoom (PTZ – Pan, Tilt and Zoom) et lanalyse. Les interfaces de gestion et de controle definies dans le present document sont decrites sous forme de services Web. LAnnexe F contient les definitions du schema XML et du langage de description de services web (WSDL – Web Service Description Language) pour les services de reseaux presentes. Cette premiere edition, conjointement avec lIEC 60839-11-31 et lIEC 62676-2-32, annule et remplace lIEC 62676-2-3:2013. Cette edition inclut les modifications techniques majeures suivantes par rapport a lIEC 62676-2-3:2013: a) ajout du service Media2; b) methodes supplementaires applicables au service dimagerie; c) suppression des methodes de duplication du service ES de dispositive; d) retrait definitif du service de dispositif danalyse et du service daffichage.
