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 60728-9 has been prepared by subcommittee 100D: Cabled
distribution systems, of IEC technical committee 100: Audio, video and multimedia systems
and equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
100/158/FDIS 100/180/RVD
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 3.
Annexes A and B form an integral part of this standard.
Annexes C, D, E and F are for information only.

The committee has decided that the contents of this publication will remain unchanged until 2006.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this standard may be issued at a later date.

INTRODUCTION
Standards of the IEC 60728 series deal with cable networks for television signals, sound
signals and interactive services including equipment, systems and installations
– for headend reception, processing and distribution of television and 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.
All kinds of networks like
– CATV-networks,
– MATV-networks and SMATV-networks,
– individual receiving networks
and all kinds of equipment, systems and installations installed in such networks, are within
the scope of this series.
The extent of this standardization work goes from the antennas, special signal source inputs
to the head-end, or other interface points to the network, up to the system outlet or the
terminal input, where no system outlet exists.
The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia
terminals, etc.) as well as of any coaxial and optical cables and accessories therefore is
excluded.

CABLED DISTRIBUTION SYSTEMS FOR TELEVISION
AND SOUND SIGNALS –
Part 9: Interfaces of cabled distribution systems
for digitally modulated signals
1 Scope
This part of IEC 60728 describes physical interfaces for the interconnection of signal
processing devices for professional CATV/SMATV headend equipment or for similar systems,
such as in up-link stations. This standard, in particular, specifies the transfer of MPEG-2 data
signals in the standardized transport layer format between devices of different signal
processing functions.
RF interfaces and interfaces to telecom networks are not covered by this standard.
In addition references are made to all other parts of the IEC 60728 series and, in particular,
for RF, video and audio interfaces, to IEC 60728-5.
For connections to telecom networks, special Data Communication Equipment (DCE) is
necessary to adapt the serial or parallel interfaces specified in this document to the bitrates
and transmission formats of the public Plesiochronic Digital Hierarchy (PDH) networks. Other
emerging technologies such as Connectionless Broadband Data Services (CBDS),
Synchronous Digital Hierarchy (SDH), Asynchronous Transfer Mode (ATM), etc. can be used
for transmitting MPEG-2 Transport Streams (TS) between remote locations. ATM is
particularly suitable for providing bandwidth on demand and it allows for high data rates.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60728. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this part of IEC 60728 are encouraged to investigate the possibility of
applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
