Cable networks for television signals, sound signals and interactive services -- Part 5: Headend equipment
This part of IEC 60728 defines the characteristics of equipment used in the headends of terrestrial broadcast and satellite receiving systems (without satellite outdoor units and without those broadband amplifiers in the headend as described in IEC 60728-3). The satellite outdoor units for FSS are described in ETSI ETS 300 158, for BSS in ETSI ETS 300 249. Test methods for both types (FSS and BSS) of satellite outdoor units are laid down in ETSI ETS 300 457.

This European Standard was approved by CENELEC on 2008-04-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in two official versions (English and German). A version in any other language
made by translation under the responsibility of a CENELEC member into its own language and notified to the
Central Secretariat has the same status as the official versions.

Foreword
The text of document 100/1244/FDIS, future edition 2 of IEC 60728-5, prepared by technical area 5,
Cable networks for television signals, sound signals and interactive services, of IEC TC 100, Audio,
video and multimedia systems and equipment, was submitted to the IEC-CENELEC parallel vote and
was approved by CENELEC as EN 60728-5 on 2008-04-01.
This European Standard supersedes EN 50083-5:2001.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2009-01-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2011-04-01
with the EN have to be withdrawn
For this European Standard the informative Annex D of IEC 60728-5:2007 shall be disregarded and
has been replaced by the normative Annex ZB, Special national conditions.
Annexes ZA and ZB have been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 60728-5:2007 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60169-8 NOTE IEC 60169-8:1986 is superseded by IEC 61169-8:2007, which is harmonized as
EN 61169-8:2007 (not modified).
