Alarm systems - CCTV surveillance systems for use in security applications - Part 5-3: Video transmission - Analogue and digital video transmission
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.

Systèmes d'alarme - Systèmes de surveillance CCTV à usage dans les applications de sécurité - Partie 5-3: Transmission video - transmission vidéo analogique et numérique
Le but du système de transmission dans une installation de télévision à circuit fermé (CCTV) est de fournir aux signaux vidéo un moyen de transmission sûr qui est mis entre les différents matériels CCTV dans des applications de sécurité, de sûreté et de surveillance. Parallèlement aux interfaces et aux systèmes de transmission vidéo à haute résolution, les signaux vidéo analogiques sont toujours utilisés à l’heure actuelle pour la transmission vidéo et donnent un balayage entrelacé et un format de l’image de 4:3. La complexité d’un système de transmission vidéo varie selon les exigences de l’installation. Des exemples de différents types de systèmes de transmission vidéo couverts par la présente Norme européenne sont donnés ci-après: a) Support de transmission par câble dédié utilisant: – du câble coaxial; – du câble en paire torsadée; – du câble à fibres optiques; b) Méthodes de transmission sans fil utilisant: – les micro-ondes; – l’infrarouge; – la transmission radio; NOTE 1 Ces méthodes de transmission s’appliquent aux signaux vidéo qui ne sont pas compressés. NOTE 2 Des signaux vidéo analogiques multiples peuvent être combinés en une seule voie physique de transmission utilisant des techniques de multiplexage. c) Interfaces vidéo analogiques à haute résolution utilisant: – VESA et VGA; d) Interfaces vidéo numériques à haute résolution sans compression utilisant: – HDMI; – DVI. La présente Norme européenne stipule les exigences minimales concernant les spécifications et les essais de performance d’une voie de transmission vidéo impliquant un transmetteur, un récepteur ou 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 présente Norme européenne. La présente Norme européenne concerne la transmission des signaux vidéo couleur et noir et blanc, conformément à l’ancien Rapport 624-4 du CCIR, 625 lignes, 50 trames par seconde et au rapport actuel ITU-R BT.624 4. La transmission vidéo basée sur l’IP est couverte par l’EN 50132-5-1 et l’EN 50132-5-2.

– 5 – EN 50132-5-3:2012 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. Each subpart offers its own (sub)clauses on scope, references, definitions, requirements. SIST EN 50132-5-3:2012
EN 50132-5-3:2012 – 6 – 1 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: a) using dedicated cable transmission media: – coaxial cable; – twisted pair cable; – fibre optic cable; b) 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. c) using analogue high-resolution video interfaces: – VESA and VGA; d) 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. SIST EN 50132-5-3:2012

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.
