Cable networks for television signals, sound signals and interactive services - Part 3-1: Methods of measurement of non-linearity for full digital channel load with DVB-C signals

IEC 60728-3-1:2012 is applicable to the methods of non-linearity measurement for cable networks which carry only digitally modulated television signals, sound signals and signals for interactive services. These methods take into account the specific signal form and behaviour of digitally modulated signals which differ from the analogue broadcast signals represented mainly by the existence of discrete carrier signals.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 3-1: Méthodes de mesure de la non-linéarité pour une charge faite seulement de porteuses en modulation numérique avec des signaux DVB-C

La CEI 60728-3-1:2012 s'applique aux méthodes de mesure de la non-linéarité pour des réseaux de distribution par câbles qui ne transportent que des signaux en modulation numérique, pour la télévision, la radiodiffusion sonore et les services interactifs. Ces méthodes prennent en compte la forme et le comportement particuliers des signaux en modulation numérique, différents des signaux de diffusion analogique, pour leur part essentiellement représentés par des porteuses discrètes non modulées.

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 of the IEC 60728 series deal with cable networks including equipment and

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

television signals, sound signals and their associated data signals and for processing,

interfacing and transmitting all kinds of signals for interactive services using all applicable

transmission media.
This includes
• CATV -networks,
• MATV-networks and SMATV-networks,
• individual receiving networks,

and all kinds of equipment, systems and installations installed in such networks.

For active equipment with balanced RF signal ports this standard applies only to those ports

which carry RF broadband signals for services as described in the scope of this standard.

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.

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 word encompasses the HFC networks used nowadays to provide telecommunications services, voice,

data, audio and video both broadcast and narrowcast.
