INTERNATIONAL ELECTROTECHNICAL COMMISSION
___________
GENERAL METHODS OF MEASUREMENT
FOR DIGITAL TELEVISION RECEIVERS
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62028 has been prepared by IEC technical committee 100: Audio,
video and multimedia systems and equipment.
The text of this standard is based on the following documents:
CDV Report on voting
100/232/CDV 100/427/RVC
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
Annexes A, B, and C form an integral part of this standard.
The committee has decided that the contents of this publication will remain unchanged until 2004.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

GENERAL METHODS OF MEASUREMENT
FOR DIGITAL TELEVISION RECEIVERS
1 Scope
IEC 62028 deals with the standard conditions and methods of measurement on digital
television receivers which receive digital television broadcast transmissions.
IEC 62028 deals with the determination of performance and allows the comparison of
equipment by listing the characteristics which are useful for specifications and by laying down
uniform measuring methods of these characteristics. Performance requirements are not
specified, since they are specified by other international, regional or domestic standards for
the systems.
It does not include the measurements specific to the transmission system, such as;
• measurements on receivers for satellite transmission systems,
• measurements on receivers for terrestrial transmission systems,
• measurements on receivers for cable transmission systems,
• measurements specific to sound channels, and
• measurements specific to data channels.
IEC 62028 does not include methods of measurement on outdoor units and antennas for
satellite reception, for which reference is required to other appropriate IEC standards.
IEC 62028 does not deal with general safety matters, for which reference is required to IEC 60065,
or other appropriate IEC safety standards, nor with radiation and immunity, which will be dealt with
by CISPR.
