Cable networks for television signals, sound signals and interactive services - Part 2-4: Interference Mitigation Filters operating in the 700 MHz and 800 MHz bands for DTT reception

This document provides requirements for passive filters intended to reduce RF interference from mobile Base Stations (BS) and User Equipment (UE) to receiving equipment and master antenna cable distribution systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful for mitigation of interference to VHF FM or DAB radio.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 2-4: Filtres d'atténuation de brouillage fonctionnant dans les bandes 700 MHz et 800 MHz pour la réception TNT

Le présent document établit les exigences relatives aux filtres passifs destinés à réduire le brouillage RF transmis par les stations de base (BS) mobiles et les matériels d'utilisateur (UE) aux matériels de réception et aux réseaux de distribution par câbles à antenne collective des signaux de radiodiffusion DVB-T et DVB-T2 dans les bandes VHF et UHF. Même s'ils sont essentiellement destinés à être utilisés avec des récepteurs et des réseaux de distribution de signaux VHF/UHF DVB-T et DVB-T2, ces filtres peuvent également être utiles dans le cadre de l'affaiblissement du brouillage sur les bandes radio VHF FM ou DAB.

Introduction

Standards and deliverables of EN 60728 series and EN 50083 series deal with cable networks including

equipment and associated methods of measurement for headend reception, processing and distribution of

television and sound signals and for processing, interfacing and transmitting all kinds of data signals for

interactive services using all applicable transmission media. These signals are typically transmitted in

networks by frequency-multiplexing techniques.
This includes, for instance:
a) regional and local broadband cable networks;
b) extended satellite and terrestrial television distribution systems;
c) individual satellite and terrestrial television receiving systems;

and all kinds of equipment, systems and installations used in such cable networks, distribution and receiving

systems.

The extent of this standardization work is from the antennas and/or special signal source inputs to the

headend or other interface points to the network up to the terminal input of the customer premises

equipment.

The standardization work will consider coexistence with users of the RF spectrum in wired and wireless

transmission systems.

The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well

as of any coaxial, balanced and optical cables and accessories thereof is excluded.

This document introduces the requirements for DTT filters with stop-bands for the 700 MHz and 800 MHz

bands. These filters are for use in individual and MATV antenna installations for reception of DTT signals

when the 700 MHz band will be used by telecommunication services in addition to the 800 MHz band.

These requirements extend those of CLC/TS 50083-2-3 for mitigation filters for LTE services operating in the

800 MHz band only and ETSI EN 303 354 V.1.1.1 (2017-03), that deals with “Amplifiers and active antennas

for TV broadcast reception in domestic premises; Harmonized standard covering the essential requirements

of article 3.2 of Directive 2014/53/EU”. The ETSI document is mainly applicable to new equipment available

on the market, while this document has the purpose to allow the existing individual and MATV antenna

installations as well as amplifiers designed for the full spectrum of band 4 and 5 for reception of DTT signals

to avoid or mitigate the interference due to the new telecommunication services when the 700 MHz band is

added to the 800 MHz band already used.
These DTT filters are not designed to be used for CATV networks.

1 Scope

This document provides requirements for passive filters intended to reduce RF interference from mobile

Base Stations (BS) and User Equipment (UE) to receiving equipment and master antenna cable distribution

systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be

used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful

for mitigation of interference to VHF FM or DAB radio.
