Video surveillance systems for use in security applications - Part 2-2: Video transmission protocols - IP interoperability implementation based on HTTP and REST services

This part of IEC 62676 specifies a compliant IP video protocol based on HTTP and REST services. Video transmission devices are often equipped with web servers that respond to HTTP requests. The HTTP response may contain XML content (for GET actions), XML response information (for SET actions), or various text/binary content (for retrieval of configuration data, etc.). REST is an approach to creating services that expose all information as resources in a uniform way. The ease of using REST is its uniform interface for operations. Since everything is represented as a resource, create, retrieve, update, and delete (CRUD) operations use the same URI. This specification leverages the features of HTTP and REST for IP video transmission. A video transmission device supporting compliance to the requirements of this standard based on HTTP and REST Services as described in this document is declared as compatible to ´IEC 62676-2 HTTP and REST interoperability.´

Systèmes de video surveillance appliqués à la sécurité -ePartie 2-2: Protocoles de transmission video sous IP - Implémentation de l’interopérabilité fondée sur les services http et REST

La CEI 62676-2-2:2013 spécifie un protocole vidéo IP reposant sur les services HTTP et REST. Les dispositifs de vidéotransmission sont souvent équipés de serveurs web qui répondent aux requêtes HTTP. La réponse HTTP peut posséder un contenu XML (pour les actions GET), des informations de réponse XML (pour les actions SET) ou divers contenus texte/binaire (pour l'extraction de données de configuration, etc.). REST est une approche de création de services qui expose uniformément toutes les informations sous forme de ressources. Un dispositif de vidéotransmission satisfaisant aux exigences de la présente Norme sur la base des services HTTP et REST tel que décrit dans le présent document est déclaré comme étant compatible avec 'l'interopérabilité HTTP et REST de la CEI 62676-2'.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62676-2-2 has been prepared by IEC technical committee 79:
Alarm and electronic security systems.
The text of this standard is based on the following documents:
FDIS Report on voting
79/436/FDIS 79/449/RVD

INTRODUCTION
The IEC Technical Committee 79 in charge of alarm and electronic security systems together
with many governmental organisations, test houses and equipment manufacturers have
defined a common framework for video surveillance transmission in order to achieve
interoperability between products.
The IEC 62676 series of standards on video surveillance system is divided into 4 independent
parts:
Part 1 System requirements
Part 2: Video transmission protocols
Part 3: Analog and digital video interfaces
Part 4 : Application guidelines (to be published)
Each part has its own clauses on scope, references, definitions and requirements
This IEC 62676-2 series consists of 3 subparts, numbered parts 2-1, 2-2 and 2-3 respectively:
IEC 62676-2-1, Video transmission protocols – General requirements
IEC 62676-2-2, Video transmission protocols – IP interoperability implementation based on
HTTP and REST services
IEC 62676-2-3, Video transmission protocols – IP interoperability implementation based on
Web services
This second subpart of this IEC 62676-2 series covers IP interoperability implementation
based on HTTP and REST services. It is based on the requirements for IP video transmission
protocols covered in IEC 62676-2-1, which defines protocol requirements to be fulfilled by any
high-level IP video device interface.

VIDEO SURVEILLANCE SYSTEMS FOR USE
IN SECURITY APPLICATIONS –

Part 2-2: Video transmission protocols –
IP interoperability implementation based
on HTTP and REST services



1 Scope
This part of IEC 62676 specifies a compliant IP video protocol based on HTTP and REST
services.
Video transmission devices are often equipped with web servers that respond to HTTP
requests. The HTTP response may contain XML content (for GET actions), XML response
information (for SET actions), or various text/binary content (for retrieval of configuration data,
etc.). REST is an approach to creating services that expose all information as resources in a
uniform way. The ease of using REST is its uniform interface for operations. Since everything
is represented as a resource, create, retrieve, update, and delete (CRUD) operations use the
same URI. This specification leverages the features of HTTP and REST for IP video
transmission.
A video transmission device supporting compliance to the requirements of this standard
based on HTTP and REST Services as described in this document is declared as compatible
to ´IEC 62676-2 HTTP and REST interoperability.´
