METHODS OF MEASUREMENT FOR DIGITAL NETWORK –

Performance characteristics of terrestrial digital
multimedia transmission network

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.
International Standard IEC 62553 has been prepared by subcommittee IEC technical
committee 103: Transmitting equipment for radiocommunication.

METHODS OF MEASUREMENT FOR DIGITAL NETWORK –

Performance characteristics of terrestrial digital
multimedia transmission network


1 Scope
When a transmission network for digital terrestrial television broadcasting (DTTB) is being
deployed, new networking technologies such as the Single Frequency Network (SFN) can be
employed excelling the conventional analogue TV systems. However, new technical evaluation
parameters are introduced for installing SFN systems. In addition new quality evaluation
methods are also established in order to achieve stable and high-quality broadcasting services
avoiding the cliff effect, which is one of the typical phenomena in the digital transmission that the
signal quality is abruptly degraded when the received C/N becomes just lower than a specific
value representing the system limit.
Given the background described above, this International Standard has the purposes of
• establishing measuring methods that enable the objective evaluation of the performance of
transmission networks so as to make stable DTTB services a reality,
• establishing a technical baseline, such as a definition of technical terms, to standardize
measuring methods.
The measurement methods described in this standard are intended for digital terrestrial
television transmission network test and validation. The measurement methods for digital
terrestrial transmitter are not included in this standard. These methods are described in
IEC 62273-1.
This standard does not give any regulations and/or mandatory requirements. The specifications
and requirements defined for each system have priority over this standard. However, there may
be some cases where details are not specified in each individual specification or different
systems should be evaluated under a common measurement method. The purpose of this
standard is to provide a common technical baseline that makes measurement results
comparable in all cases.

4.1 Definitions and classifications of digital terrestrial TV transmission network
4.1.1 General
The digital terrestrial broadcasting transmission networks defined in this standard consist of two
or more Digital Tv transmitters, relay lines (SDH or PDH contribution link: e.g. satellite, ATM
radio, ATM optical fibre, IP Ethernet VLAN), broadcast-wave relay stations (called Gap-Filler or
Transposer) through which the same broadcasting program is transmitted. Figure 1 shows an
example of the transmission network.
The network is classified in 4.1.2 and 4.1.3 according to the following conditions
a) Assigned frequencies of each transmitter station which compose the network.
b) Signal transmission method between transmitter stations.
