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.
Figure 4 to Figure 9 have been amended to take into account the level requirement for digital
signals only.
Although the upper frequency range of terrestrial broadcast signals depends on the allocation
frequency plan of each region (e.g. in Europe it is 694 MHz, the 700 MHz and 800 MHz bands
being assigned to telecommunication services), the upper frequency range into the cable
networks can be maintained at 862 MHz in order to maximise the number of channels to be
distributed in the cable networks, assuming that sufficient immunity (screening efficiency) to
signals radiated in the 700 MHz and 800 MHz bands is provided.

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

1 Scope
This part of IEC 60728-101 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).
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.
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.
