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
7 RTS Request To Send IRD
8 CTS Clear To Send modem
9 RI Ring Indicator modem

EN 50201:2001 - 8 -

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.
4.3.1.1.2 PSTN link interface

The modem shall be equipped with RJ 11 (6 contact) female connector with pin arrangement as follows:

Pin number Name Function
3 PSTN electrical connection
4 PSTN electrical connection

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:

Pin number Name Function Source
2 RXD Receive Data modem
3 TXD Transmit Data IRD
5 GND Signal Ground
---------------------- Page: 10 ----------------------
SIST EN 50201:2009
- 9 - EN 50201:2001
4.3.2.2 RF interface to CATV/SMATV network
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

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.

NOTE 1 All CVBS related features from PAL services (like VPS, teletext ) which are available on the Peritelevision connector should be

made available as usual.
For teletext, there are two possibilities:
- the set top box contains a teletext decoder and provides telet
