Video surveillance systems for use in security applications - Part 3: Analog and digital video interfaces

IEC 62676-3:2013 specifies physical, electrical and software interface (non-IP) specifications of analog and digital video interface in video surveillance systems (so far called CCTV) applications. Video interfaces are used both for connection and transmission of surveillance video, audio and control signals. This International Standard applies strictly to Video Surveillance Systems. This standard is based on broadcast television standards and other standards, and it defines the minimum requirements for analog and digital video interfaces to meet VSS's requirements, interoperability and de facto practice.

La CEI 62676-3:2013 spécifie les spécifications relatives aux interfaces physiques, électriques et logicielles (non-IP) de l'interface vidéo analogique et numérique dans les applications des systèmes de vidéosurveillance (auparavant appelés CCTV). Les interfaces vidéo sont utilisées la connexion et aussi la transmission des signaux de vidéo surveillance, des signaux audio et des signaux de commande. La présente Norme internationale s'applique strictement aux systèmes de vidéosurveillance. La présente norme est basée sur des normes de télévision par diffusion et d'autres normes. Elle définit également les exigences minimales pour les interfaces vidéo analogiques et numériques satisfassent aux exigences concernant les VSS, à l'interopérabilité et la pratique de facto.

Video nadzorni sistemi za varnostne aplikacije - 3. del: Analogni in digitalni video vmesniki (IEC 62676-3:2013)

Standard IEC 62676-3:2013 določa fizične in električne specifikacije ter specifikacije vmesnika programske opreme (brez IP-ja) analognih in digitalnih video vmesnikov v video nadzornih sistemih (ki so se doslej imenovali CCTV) za varnostne aplikacije. Video vmesniki se uporabljajo za povezovanje in prenos video, zvočnih in kontrolnih nadzornih signalov. Ta mednarodni standard dosledno velja za video nadzorne sisteme. Ta standard temelji na standardih za digitalno televizijsko radiodifuzijo in drugih standardih ter določa minimalne zahteve za analogne in digitalne video vmesnike, da izpolnijo zahteve VSS, interoperabilnosti in dejanske prakse.

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 62676-3 has been prepared by technical committee 79: Alarm and

electronic security systems.
The text of this standard is based on the following documents:

INTRODUCTION

The IEC Technical Committee 79 in charge of alarm and electronic security systems together

with many governmental organizations, test houses and equipment manufacturers has defined

a common framework for video surveillance transmission in order to achieve interoperability

between products.

The IEC 62676 series of standards on video surveillance systems is divided into four

independent parts:
Part 1: System requirements
Part 2: Video transmission protocols
Part 3: Analog and digital video interfaces
Part 4: Application guidelines

Each part offers its own clauses on scope, references, definitions and requirements.

This IEC Standard Part 3 of IEC 62676 specifies physical, electrical interface and software

specifications of analog and digital video interfaces in Video Surveillance Systems (VSS), so

far called Closed Circuit Television (CCTV).

For analog video interfaces, analog video signal such as Composite Video is still the most

commonly used interface among Video Surveillance Systems equipment. Though broadcast

television industry has adopted composite video standards (e.g. NTSC, PAL), they have not

been consistently applied for Video Surveillance Systems applications and it is important to

standardize the interface to ensure interoperability between Video Surveillance Systems.

Also, as broadcast is moving towards digital, there are many possibilities to improve the

performance with these new Video Interfaces compared to conventional Analog Video

Interface, and thus it is important to standardize those new Analog Video interface and also

Digital Video Interface to ensure interoperability among Video Surveillance Systems using

these new interfaces.

For digital video interface, IEC 62676-1-2, IEC 62676-2-1, IEC 62676-2-2 and IEC 62676-2-3

focus on video transmission and compressed IP video transmissions by specifying internet (IP)

and higher layers. IEC 62676-3 completes the communication layer specification by

describing uncompressed digital video and two lowest layer protocols such as physical and

network access.

VIDEO SURVEILLANCE SYSTEMS FOR USE
IN SECURITY APPLICATIONS –
Part 3: Analog and digital video interfaces
1 Scope

This Part of IEC 62676 specifies physical, electrical and software interface (non-IP)

specifications of analog and digital video interface in video surveillance systems (so far called

CCTV) applications. Video interfaces are used both for connection and transmission of

surveillance video, audio and control signals. Through video interfaces, video surveillance

systems can be put together by connecting various components such as image capturing

devices, image handling devices, etc. This International Standard ensures interoperability

among various video surveillance components.

This International Standard applies strictly to Video Surveillance Systems. This standard is

based on broadcast television standards and other standards, and it defines the minimum

requirements for analog and digital video interfaces to meet VSS’s requirements,
interoperability and de facto practice.
