Interfaces for DVB-IRD
This European Standard is an application standard, identifying recommended interfaces for connections of digital video broadcast integrated receiver decoder (DVB-IRD) equipment. If a recommended interface is supported, then the full specification of that interface, which may include options, applies. Interfaces not mentioned in this document are not excluded and especially interfaces which are under development at the time of writing of this document may be added at a later stage. For mechanical and electrical details of the interfaces, reference is made to existing standards of IEC or CENELEC wherever possible, or standards which are known to be in an advanced state of development.

This European Standard was prepared by the DVB-TM Ad hoc group on Physical Interfaces, together
with the former Technical Committee CENELEC TC 203, Electronic entertainment and educational
systems for household and similar use (in July 1998, TC 203 has become part of TC 206, Consumer
equipment for entertainment and information and related sub-systems).
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 50201 on 2000-04-01.
This European Standard supersedes EN 50201:1998.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2002-07-01
- latest date by which national standards conflicting
with the EN have to be withdrawn (dow) 2003-04-01
Annexes designated "informative" are given for information only.

4 Interface requirements for DVB-IRDs
4.1 RF input in the satellite IF range
This clause specifies the interface in case of individual dish antenna or SMATV-IF (analogue and digital)
installations.
---------------------- Page: 8 ----------------------
SIST EN 50201:2009
- 7 - EN 50201:2001
4.1.1 Polarization switch, LNB's band and first IF input selection
The control signal to switch the polarisation, the control signal to select the upper or lower band of the
LNB and the 1st IF input from the LNB to the DVB-IRD shall be as specified in EN 61319-1, clause 5.
The connector is specified in EN 60169-24 (also known as the F-connector), the impedance is 75 � and
output return losses are specified in ETS 300784.
4.1.2 Azimuth control of a polar mount dish antenna
The control signal for the azimuth control of a polar mount dish antenna shall be as specified in
EN 61319-1, clause 6.
4.2 RF I/O in the VHF/UHF range
4.2.1 RF input
The RF input in the case of CATV installations, SMATV System A or SMATV-S installations, or in the
case of terrestrial reception shall be as follows:
- covers the VHF/UHF frequency bands (47 MHz - 862 MHz);
- 75 � coaxial;
- connector HD 134.2 (IEC 60169-2), female connector on the DVB-IRD.
4.2.2 RF output
The interface for RF output signals shall be as specified in 4.2.1 except for the connector which is
HD 134.2 (IEC 60169-2) male version. RF output shall support either loop through only, RF modulated
output from the DVB-IRD or both. In case of loop through, the modulator should output the VHF/UHF
frequency bands as specified in 4.2.1. The channel to be used for RF modulated output depends on local
circumstances, i.e. occupation of available channels by either terrestrial or cable programs (see
informative Annex B). It is recommended to support the channel range 21 to 69 in UHF.
4.3 Modem interface
4.3.1 PSTN modem
A PSTN modem interface provides a low bit rate data channel.
4.3.1.1 External modem
4.3.1.1.1 DTE/DCE interface
The modem shall support
a) an interface lead with a 9 pin D-type connector with male shell and female contacts, using
RS232C interface levels. The DVB-IRD is seen as the Data Terminal Equipment (DTE) and shall
be equipped with the mating connector. The pin arrangement shall be as follows:
Pin number Name Function Source
1 DCD Carrier Detection modem
2 RXD Receive Data modem
3 TXD Transmit Data IRD
4 DTR Data Terminal Ready IRD
5 GND Signal Ground
6 DSR Data Set Ready modem

b) automode selection ITU-T V.21, V.23 (1200/75), V.22 or V.22 bis transmission protocols (one of
these as a minimum). Asynchronous working with one or two stop bits and with or without parity
shall be possible. It is recommended that V.32, V.32 bis and V.34 support is included and that the
design does not preclude the addition of future enhancements,
c) hardware flow control (RTS/CTS) in addition to XON/XOFF flow control,
d) control by the Hayes AT command set,
e) autocalling, ITU-T V.25 autoanswering and an autologon feature,
f) ITU-T V.42 error correction and V.42 bis data compression.
NOTE V.25 and V.42 are optional extras for a modem interface.

NOTE 1 PSTN (GSTN) working implies using a PSTN interface cable terminating in a plug which meets national connection
requirements given in ETS 300001 (NET4). The compliance to this interface implies the need for the product to be subjected to type
approval by the National regulatory body.
NOTE 2 Approval under the Terminal Equipment Directive 91/263/EEC.
4.3.1.2 Integrated modem
The internal modem shall meet the same requirements as the external modem as specified in 4.3.1.1,
with the exception of providing the 9 pin interface connector as specified in 4.3.1.1.1 a).
4.3.2 CATV and SMATV modem
A CATV/SMATV modem interface provides a bi-directional data channel. The suitable data rate and the
kind of operation depends on the performance of the service.
4.3.2.1 DTE/DCE interface
An external modem shall be equipped with an interface lead with a 9 pin D-type connector with male
shell and female contacts, using RS232 interface levels. The DVB-IRD is the Data Terminal Equipment
(DTE) and shall be equipped with the mating connector. The pin arrangement shall be as follows:

The RF interface for both an internal and an external modem shall be as follows:
- impedance 75 �;
- connector HD 134.2 (IEC 60169-2), female on the modem.
It is recommended to use, for the carrier in the forward direction
a) for CATV, SMATV System A and SMATV-S modem, the range of 47 MHz to 862 MHz,
b) for SMATV-IF modem, the range above 850 MHz.
It is recommended to use, for the carrier of the return path, the range of 5 MHz to 65 MHz (to be
confirmed).
The choice of carrier frequencies depends on the design of the CATV/SMATV network.
4.4 Video signals
Analogue video signal output can be either baseband in RGB, Y/C (S-VHS) or CVBS format or
modulated on an RF carrier. The MPEG2 Transport Stream is used to transmit the digital video signals
on a high performance serial interface, see 4.6.3.
4.4.1 Baseband signals
Matching values for analogue baseband signals 1 V . For detailed specifications see any one of the
pp
following standards:
- EN 61938: Preferred matching values of analogue signals;
- IEC 60933-1: 21 contact connector;
- EN 50049-1: Peritelevision connector;
- EN 50157-1: AV.link.
