Cable networks for television signals, sound signals and interactive services - Part 101-1: RF cabling for two-way home networks with all-digital channels load
IEC 60728-101-1:2023 provides the requirements and describes the implementation guidelines of RF cabling for two-way home networks; it is applicable to any home network that distributes signals provided by CATV/MATV/SMATV cable networks (including individual receiving systems) having a coaxial cable output. It is also applicable to home networks where some part of the distribution network uses wireless links, for example in place of the receiver cord.
This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz band.
In a building divided into apartment blocks, the distribution of the signals inside the home starts from the home network interface (HNI) up to the system outlet or terminal input. The requirements at the system outlet are given in IEC 60728-101:2016, Clause 5 and the requirements at the HNI are given in IEC 60728-101:2016, Clause 7. In Clause 5 of this document, additional requirements are given.
This document deals with various possibilities to distribute signals in a home network, using coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords.
This document gives references to basic methods of measurement of the operational characteristics of the home cable network in order to assess its performance.
All requirements refer to the performance limits, which are obtained between the input(s) at the home network interface (HNI) and the output at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not used, the above applies to the terminal input.
The present document also provides limits for the accumulation of degradations if the home network is subdivided into a number of parts, using different transmission media (e.g. coaxial cabling, balanced cabling, optical cabling, wireless links).
Clause 5 defines the performance limits measured at system outlet or terminal input for an unimpaired (ideal) test signal applied at the HNI. Under normal operating conditions for any digital channel and meeting these limits, the cumulative effect of the impairment of any single parameter at the HNI and that due to the home network produces signals not worse than the requirements given in IEC 60728-101-2. For digitally modulated signals, the quality requirement is a QEF (quasi error-free) reception.
This document describes the physical layer connection for home networks. Description of protocols required for layer 2 and higher layers is out of the scope of this document. Logical connections between devices within the home network are therefore not always guaranteed.
This International Standard is to be used in conjunction with IEC 60728-101:2016.
Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs – Partie 101-1: Câblage RF pour réseaux domestiques bidirectionnels soumis à une charge de porteuses exclusivement numériques
L'IEC 60728-101-1:2023 formule les exigences et présente les lignes directrices de mise en œuvre d'un câblage RF pour réseaux domestiques bidirectionnels. Elle s'applique à tous les réseaux domestiques qui distribuent les signaux transmis par les réseaux de distribution par câble CATV/MATV/SMATV (y compris les systèmes individuels de réception) qui disposent d'une sortie à câble coaxial. Elle s'applique également aux réseaux domestiques dans lesquels une partie du réseau de distribution utilise des liaisons sans fil (en lieu et place d'un cordon de récepteur, par exemple).
La présente partie de l'IEC 60728 s'applique donc au câblage RF pour réseaux domestiques bidirectionnels avec cordons câblés ou liaisons sans fil à l'intérieur d'une pièce, et concerne principalement les signaux de télévision et les signaux de radiodiffusion sonore compris entre 5 MHz et 3 300 MHz environ. La plage de fréquences est étendue à 6 000 MHz pour les techniques de distribution qui remplacent les cordons câblés par une communication bidirectionnelle sans fil à l'intérieur d'une pièce (ou d'un nombre restreint de pièces adjacentes) qui utilise la bande comprise entre 5 GHz et 6 GHz.
La distribution des signaux à l'intérieur d'un bâtiment divisé en blocs d'appartements s'étend de l'interface du réseau domestique (HNI) à la prise d'abonné ou à l'entrée de terminal. Les exigences au niveau de la prise d'abonné sont données à l'Article 5 de l'IEC 60728‑101:2016. Les exigences au niveau de l'interface du réseau domestique sont données à l'Article 7 de l'IEC 60728-101:2016. L'Article 5 du présent document fournit des exigences supplémentaires.
Le présent document traite des différentes possibilités de distribution des signaux dans un réseau domestique, à l'aide de câbles coaxiaux, de câbles à paires symétriques, de câbles à fibres optiques (verre ou plastique) ainsi que de liaisons sans fil à l'intérieur d'une pièce (ou d'un nombre restreint de pièces adjacentes) pour remplacer les cordons câblés.
Le présent document fait référence à des méthodes de mesure de base des caractéristiques opérationnelles du réseau domestique de distribution par câble afin d'évaluer ses performances.
Toutes les exigences font référence aux limites de performances qui sont obtenues entre l'entrée ou les entrées de l'interface du réseau domestique (HNI) et la sortie de toute prise d'abonné lorsqu'elle est équipée d'une résistance de terminaison égale à l'impédance de charge nominale du système, sauf spécification contraire. Si les prises d'abonné ne sont pas utilisées, les éléments ci-dessus s'appliquent à l'entrée de terminal.
Le présent document fournit également des limites concernant l'accumulation des dégradations si le réseau domestique est divisé en plusieurs parties qui utilisent différents supports de transmission (par exemple câblage coaxial, câblage symétrique, câblage optique, liaisons sans fil).
L'Article 5 définit les limites de performances mesurées au niveau de la prise d'abonné ou de l'entrée de terminal pour un signal d'essai non dégradé (idéal) au niveau de l'interface du réseau domestique. Dans les conditions normales de fonctionnement d'un canal numérique et en respectant ces limites, l'effet cumulatif de la dégradation d'un seul paramètre au niveau de l'interface du réseau domestique et de celle due au réseau domestique génère des signaux au moins conformes aux exigences données dans l'IEC 60728-101-2. Pour les signaux à modulation numérique, l'exigence de qualité est une réception quasi sans erreurs (QEF, Quasi Error-Free).
Le présent document décrit la connexion de couche physique des réseaux domestiques. La description des protocoles exigés pour la couche 2 et les couches supérieures ne relève pas du domaine d'application du présent document. Les connexions logiques entre les dispositifs à l'intérieur d'un réseau domestique ne sont donc pas toujours assurées.
La présente Norme internationale doit être utilisée conjointement avec l'IEC 60728-101:

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.

INTRODUCTION
Standards and deliverables of the IEC 60728 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
• regional and local broadband cable networks,
• extended satellite and terrestrial television distribution systems,
• 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.
The reception of television signals inside a building requires an outdoor antenna and a
distribution network to convey the signal to the TV receivers.
This part of the IEC 60728 deals with the requirements and implementation guidelines for a
home network that can be realised with different techniques. The following types of home
networks (HN) are possible:
• passive coaxial home network;
• active coaxial home network;
• different home network types (cases A to D shown in Figure 1).
Figure 1 shows typical situations that are possible when considering RF home networks.
The RF home network can be realised using coaxial cables, balanced cables, optical cables or
radio links.
This document considers digital signals only and is based on IEC 60728-101 dealing with
system performance of forward paths loaded with digital channels only. For RF cable systems
loaded with analogue and digital signals, refer to IEC 60728-1-1 ED2.
