Foreword
This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Satellite Earth Stations
and Systems (SES).
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.5] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.2].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in ETSI
EN 303 372-1 [i.1].

1 Scope
The present document applies to InDoor Units (IDUs) for satellite broadcast reception. An indoor unit gets on an input
interface the signal that has been received from satellite and processed by the OutDoor Unit (ODU). It performs carrier
selection, demodulation, audio and video decoding.
IDUs in the scope of the present document demodulate broadcast carriers by means of a Zero IF tuner.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies to this part of
functionality as well as the remaining part in the IDU.
The indoor unit may be integrated with a domestic television receiver.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.
