This 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 standard. This standard covers the transmission of colour and black and white video signals in accordance with CCIR Report 624-4, 625 lines, 50 fields per second. This standard is not applicable for transmission systems which use in the whole system or in parts thereof compressed video signals in any way. NOTE Compression techniques use methods to match the information content of signals to the best channel capacity. The various test signals of this standard applied on different methods to compress video signals can supply results which meet the requirements of this standard. However, it should not be concluded from such results that those parts of transmission systems using methods to compress video signals are able to transmit a real video signal with a high information content in the correct way. Methods to compress video signals can use techniques reducing video signals without any loss of information (so called “redundant reduction”) or with some loss of information (so called “irrelevance reduction”).

Systèmes d'alarme - Systèmes de surveillance CCTV à usage dans les applications de sécurité - Partie 5: Transmission video
La présente norme stipule les exigences minimales concernant les spécifications et les essais de performance d’une voie de transmission vidéo impliquant un transmetteur, un récepteur et des dispositifs intermédiaires associés au support de transmission choisi, voie destinée à être utilisée dans les systèmes de surveillance CCTV. Les matériels de transmission vidéo peuvent être combinés avec des fonctions complémentaires, par exemple avec des transmissions audio ou de données. Ces fonctions ne font pas partie de la norme. La présente norme concerne la transmission des signaux vidéo couleur et noir et blanc, conformément au Rapport 624-4 du CCIR, 625 lignes, 50 trames par seconde. La présente norme ne s’applique pas aux systèmes de transmission qui utilisent en totalité ou en partie des signaux vidéo compressés de différents types. NOTE Les techniques de compression utilisent des méthodes pour conserver le contenu informatif des signaux avec la meilleure capacité de transmission. Les différents signaux de test de la présente norme s’appliquant aux différentes méthodes de compression des signaux vidéo peuvent fournir des résultats qui se rapprochent des exigences de la présente norme. Toutefois, il ne faudra pas conclure à partir de ces résultats que ces types de systèmes de transmission utilisant des méthodes de compression de signaux vidéo sont capables de transmettre un réel signal vidéo avec un haut contenu informatif de bonne qualité. Les méthodes de compression de signaux vidéo peuvent utiliser des techniques réduisant les signaux vidéo sans aucune perte d’information (dites « à compression redondante ») ou avec une petite perte d’information (dites « à compression irrélévante »).

Introduction
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 equipment in
security, safety and monitoring applications.
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 standard are
as follows:
a) Using cable transmission media :
− Coaxial cable,
− Twisted pair cable,
− Fibre optic cable.
b) Using wireless transmission methods :
− Microwave,
− Infra red,
− Radio transmission.
NOTE Multiple video signals may be combined in one physical transmission path using multiplexing techniques.
1 Scope
This 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 standard.
This standard covers the transmission of colour and black and white video signals in
accordance with CCIR Report 624-4, 625 lines, 50 fields per second.
This standard is not applicable for transmission systems which use in the whole system or in
parts thereof compressed video signals in any way.
NOTE Compression techniques use methods to match the information content of signals to the best channel
capacity. The various test signals of this standard applied on different methods to compress video signals can
supply results which meet the requirements of this standard. However, it should not be concluded from such results
that those parts of transmission systems using methods to compress video signals are able to transmit a real video
signal with a high information content in the correct way.
Methods to compress video signals can use techniques reducing video signals without any loss of information (so
called “redundant reduction”) or with some loss of information (so called “irrelevance reduction”).
