Foreword

This document (EN 50132-5-3:2012) has been prepared by CLC/TC 79, "Alarm systems".

The following dates are fixed:

latest date by which this document has to be implemented at national level by publication of an identical national standard

or by endorsement (_dop) _2O13.O5-15

latest date by which the national standards conflicting with

this document have to be withdrawn (dow) 2015-05-15

This document, together with EN 50132-5-1:2011 and EN 50132-5-2:2011, supersedes EN 50132-5:2001.

This document is a revision of the former video transmission standard EN 50132-5:2001 with only one additional new Clause 9, 'High resolution video interface standards & transmission requirements'.

EN 50132 consists of the following parts, under the general title “Alarm systems - CCTV surveillance systems for use in security applications":

• Part 1: System requirements;

• Part 5-1: Video transmission - General video transmission performance requirements;

• Part 5-2: Video transmission - IP video transmission protocols;

• Part 5-3: Video transmission - Analogue and digital video transmission;

• Part 7: Application guidelines.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.Introduction

The European Electrotechnical Standardisation Organisation for Alarm Systems together with many governmental organisations, test houses and equipment manufacturers has defined a common framework for Surveillance Video Transmission in order to achieve interoperability between products.

EN 50132-5 is divided into 3 independent subparts:

• Part 5-1: Video transmission - General video transmission performance requirements;

Part 5-2: Video transmission - IP video transmission protocols;

Part 5-3: Video transmission - Analogue and digital video transmission.

1. Each subpart offers its own (sub)clauses on scope, references, definitions, requirements.Scope

The purpose of the transmission system in a closed circuit television (CCTV) installation is to provide reliable transmission of video signals between the various CCTV equipments in security, safety and monitoring applications.

Along with high-resolution video interfaces and transmission, the analogue video signals are still in use today for video transmission and offer interlaced scanning and the film aspect ratio of 4:3.

The complexity of a video transmission system varies in accordance with the requirements of the installation.

Examples of the different types of video transmission systems covered by this European Standard are as follows:

1. using dedicated cable transmission media:

• coaxial cable;

• twisted pair cable;

• fibre optic cable;

2. using wireless transmission methods:

• microwave;

• infrared;

• radio transmission;

NOTE 1 These transmission methods apply to non-compressed video signals.

NOTE 2 Multiple analogue video signals may be combined in one physical transmission path using multiplexing techniques.

3. using analogue high-resolution video interfaces:

- VESA and VGA;

4. using digital uncompressed high-resolution video interfaces:

• HDMI;

• DVI.

This European Standard specifies the minimum requirements for the specification and testing of the performance of a video transmission channel involving transmitter, receiver or intermediate devices associated with the selected transmission media, for use in CCTV surveillance systems.

Video transmission equipment may be combined with additional functions, e.g. for audio or data transmission. These functions are not included in this European Standard.

This European Standard covers the transmission of colour and black and white video signals in accordance with the former CCIR Report 624-4, 625 lines, 50 fields per second and today ITU-R Report BT.624-4.

IP based video transmission is covered in EN 50132-5-1 and EN 50132-5-2.

3. Terms, definitions and abbreviations

   1. Terms and definitions

For the purposes of this document, the following terms and definitions apply.

analogue

continuous electrical signal that carries information in the form of variable physical values, such as amplitude or frequency modulation and that moves through a continuous range of settings or levels

analogue components

video signals in which a continuously variable voltage or current (rather than a set of digital numbers) represents a pixel

3.1.3

analogue interface

interface between a video source and a video input in which pixel colours are determined by the voltage levels on three output lines (RGB)

Note 1 to entry: Theoretically, an unlimited number of colours can be supported by this method (24 bits per pixel allows 16 777 216 colours). The voltage level on any line varies between 0 V (for black) to about 700 mV (for maximum brightness).

3.1.4

analogue monitor

video monitor which accepts analogue signals such as composite video, RGB & sync, Y/C, YUV and any combination of these formats

Note 1 to entry: The signals transmitted to an analogue monitor are usually between 0 V and 1 V and use 75-Q coaxial cables.

3.1.5

aspect ratio

relationship of width and height of an image

EXAMPLE For standard CCTV monitor, the aspect ratio is 4:3. The HD video format has an aspect ratio of 16 to 9 (16:9).

3.1.6

average picture level

average signal level with respect to blanking during the active picture time, expressed as a percentage of the difference between the blanking and reference white levels

3.1.7

bandwidth

frequency range of a signal

3.1.8

blanking level

voltage level produced at the end of each horizontal picture line which separates the portion of the video signal containing the picture information from the one containing the synchronizing information

3.1.9

channel

specified frequency band for the transmission and reception of signals

3.1.10

chroma

depth or saturation of colour

Note 1 to entry: The (B, D, G, H, I) PAL video signal contains two pieces that make up what you see on the screen: the black and white (luma) part, and the colour part, where chroma is the colour part and can be further broken down into two properties of colour: hue and saturation; described as single pel representing one of the two colour difference signals related to the primary colours in the manner defined in the bit stream. The symbols used for the colour difference signals are Cr and Cb.

3.1.11

chrominance

data that represents one of the two colour difference signals Cr and Cb in a video picture, which can be further broken down into two properties of colour: hue and saturation

Note 1 to entry: See also chroma in 3.1.10.

3.1.12

chrominance signal

part of the video signal that contains the colour information

Note 1 to entry: In composite video, the chrominance signal is multiplexed at a higher frequency than the signal and transmitted down the same cable. In S-VHS, this signal is transmitted along a separate cable.

3.1.13

colour depth

number of bits used for a pixel, determining the maximum number of colours that can be displayed at one time

3.1.14

component

CCTV system in which chrominance and luminance are distributed separately

3.1.15

component analogue

unencoded output of a camera or recorder, etc., consisting of three primary colour signals: red, green, and blue (RGB) that together convey all necessary picture information

Note 1 to entry: In some component video formats, these three components have been translated into a luminance signal and two colour difference signals, for example, Y, B-Y, R-Y.

3.1.16

component colour

structure of a video signal wherein the R', G', and В' signals are kept separate from each other or wherein luminance and two band-limited colour-difference signals are kept separate from one another

Note 1 to entry: The separation may be achieved by separate channels, by time-division multiplexing or by a combination of both.

3.1.17

component video

analogue component

video which exists in the form of three separate signals, all of which are required in order to specify the colour picture completely

Note 1 to entry: Most CCTV video signals consist of combined (composite) video signals, composed of luminance (brightness) information, chrominance (colour) information, and sync information.

Note 2 to entry: Component video comes in several varieties: RGB (red, green, blue), YUV (luminance, sync, and red/blue) and Y/C (luminance and chrominance), used by S-Video systems.

3.1.18

composite

1. CCTV system in which chrominance and luminance are combined into a single signal, as they are in PAL;

2. any single signal comprised of several components

3.1.19

Note 1 to entry: It is equal to ten times the logarithm of the ratio of the two the iris.

3.1.25

distortion

changes in luminance or chrominance of a video signal producing improper contrast, faulty luminance levels, twisted images, erroneous colours and snow

3.1.26

frequency response

measure for the quality of reproduction of various frequencies by a circuit or device

Note 1 to entry: If the frequency response of a video processor is adequate, there is no deterioration in image quality at the bandwidth extremes. For PAL video, the bandwidth is 5,5 MHz.

3.1.27

gain

measure of amplification expressed in dB

3.1.28

impedance

input and output characteristic of an electrical system measured in ohms with CCTV systems having 75-0 impedance throughout

3.1.29

insertion loss

diminishment of a video signal’s strength by the inclusion of an electronic device into a transmission line

3.1.30

luminance

measurement of the intensity of light in a colour

Note 1 to entry: Luminance corresponds to the Y value in YUV colour space.

3.1.31

modulate

change or vary some signal parameter such as varying the amplitude of a signal for amplitude modulation or the frequency of a signal for frequency modulation

EXAMPLE A modulator is the circuit that modulates the signal.

3.1.32

monitor

device that converts electronic signals into the video image that was generated by the camera and lens

3.1.33

multiplexing
