Cable networks for television signals, sound signals and interactive services - Part 1-2: Performance requirements for signals delivered at the system outlet in operation

IEC 60728-1-2:2014 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. It is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for home 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 frequency band. This second edition cancels and replaces the first edition published in 2009, and constitutes a technical revision. It includes the following technical: update of performance requirements in Clause 7 to include those for DVB-T2 signals.
This publication is to be read in conjunction with IEC 60728-1:2007.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 1-2: Exigences de performance relatives aux signaux délivrés à la prise terminale, en fonctionnement

L'IEC 60728-1-2:2014 décrit les exigences minimales de qualité en fonctionnement des signaux à la prise d'abonné ou à la borne d'entrée du terminal et décrit les critères d'addition des dégradations, celles présentes dans les signaux reçus, et celles produites par le réseau de distribution par câbles CATV/MATV/SMATV, ceci comprenant les systèmes de réception individuels. Elle s'applique aux réseaux de distribution par câbles pour les signaux de télévision, de radiodiffusion sonore et des services interactifs fonctionnant entre environ 5 MHz et 3 000 MHz. La bande de fréquences est étendue à 6 000 MHz pour les techniques de distribution domestique où des cordons filaires sont remplacés par une communication bidirectionnelle sans fil à l'intérieur d'une pièce (ou d'un nombre restreint de pièces adjacentes) utilisant la bande de fréquences de 5 GHz à 6 GHz. Cette deuxième édition annule et remplace la première édition parue en 2009, dont elle constitue une révision technique. Elle inclut les modifications suivantes: mise à jour des exigences de qualité de l'Article 7 afin d'inclure les exigences pour les signaux DVB-T2.

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.

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. In a building divided into

apartment blocks, the signals received by the antennas are distributed by the MATV/SMATV

cable network up to the home network interface (HNI). The television signals are then

distributed (inside the home) by home networks (HN) of various types up to the system outlet

or terminal input. The cable network can support two way operation, from the system outlet

(or terminal input) towards the headend.

The home network can use 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.

IEC 60728-1-2 (this standard) deals with the requirements to be fulfilled at the system outlet

or terminal input, when the CATV/MATV/SMATV system is in operation.

These performance requirements for signals at the system outlet or terminal input in operation

are derived from considerations of the characteristics of the received signals at the input of

the headend (see Clause 6 of IEC 60728-1:2014) and the summation of the impairments

produced by the headend, the CATV/MATV/SMATV network and the home network, when the

requirements given in IEC 60728-1:2014 and IEC 60728-1-1 are fulfilled.

This standard gives the guidelines for calculation of the operational characteristics at system

outlet, taking into account the performance requirements of the CATV/MATV/SMATV network,

of the home networks and of the received signals, given in the International Standards

IEC 60728-1:2014 and 60728-1-1.

Figure 1 shows the main sections of a general CATV/MATV/SMATV system, indicating the

parts of the IEC 60728-1 series where the relevant performance requirements are indicated.

---------------------- Page: 8 ----------------------
IEC 60728-1-2:2014 © IEC 2014 – 7 –

• The requirements for the signals received at the headend are given in Clause 6 of

IEC 60728-1:2014.
• The requirements for the CATV/MATV/SMATV cable network, assuming an unimpaired
input signal at the input of the headend, up to the system outlet are given in
IEC 60728-1:2014, Clause 5.
• The requirements for the CATV/MATV/SMATV cable network up to the home network

interface (HNI) are given in IEC 60728-1:2014, Clause 7, assuming an unimpaired input

signal at the input of the headend.

• The specific requirements from HNI to the system outlet or terminal input are given in

IEC 60728-1-1:2014, Clause 5, assuming an unimpaired input signal at the HNI.

• The requirements at the system outlet in operation are given in Clause 7 of this standard.

The expression in operation means that the received signals, with their impairments, are

applied to the headend input of the CATV/MATV/SMATV cable network. The requirements at

the system outlet in operation are derived, therefore, by summing the impairments of the

various cascaded parts of the system and of the input signal.

When a change of signal format from analogue to analogue (e.g. from FM to AM-VSB) or from

digital to digital (e.g. from QPSK to QAM) or from digital to analogue (e.g. from DVB-S/S2 to

AM-VSB or DVB-T to AM-VSB) is made at the headend, the summation of the impairments

that produce a relaxation of requirements at system outlet does not apply. Such a case will be

the equivalence of unimpaired signals applied at the headend input. Therefore, the

requirements at system outlet given in IEC 60728-1:2014 apply.

This standard also provides references for the basic methods of measurement of the

operational characteristics of the downstream cable network in order to assess its

performance.

All requirements refer to the performance limits to be achieved in operation 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.

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) the accumulation of

degradations should not exceed the figures given below.

NOTE Performance requirements of return paths as well as special methods of measurement for the use of the

return paths in cable networks are described in IEC 60728-10.

CABLE NETWORKS FOR TELEVISION SIGNALS,
SOUND SIGNALS AND INTERACTIVE SERVICES –
Part 1-2: Performance requirements for signals
delivered at the system outlet in operation
1 Scope

This part of IEC 60728 provides the minimum performance requirements to be fulfilled in

operation at the system outlet or terminal input and describes the summation criteria for the

impairments present in the received signals and those produced by the CATV/MATV/SMATV

cable network, including individual receiving systems.

In a building divided into apartment blocks, the signals received by the antennas are

distributed by the MATV/SMATV cable network up to the home network interface (HNI). The

television signals are then distributed (inside the home) by home networks (HN) of various

types up to the system outlet or terminal input. The cable network can support two way

operation, from the system outlet (or terminal input) towards the headend.

The home network can use 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 part of IEC 60728 is applicable to cable networks intended for television signals, sound

signals and interactive services operating between about 5 MHz and 3 000 MHz. The

frequency range is extended to 6 000 MHz for home 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 frequency band.
