THIS MANUAL DESCRIBES FEATURES ASSOCIATED WITH IRD-3101 FIRMWARE VERSION 3.25
1.2 Introduction
The IRD-3101 provides MPEG-2 decoding of ASI and IP transport streams to SD video. It also provides processing of
key video and audio parameters, and signal probing functions for feed aggregation, distribution, and monitoring
applications by broadcasters and TV service providers.
DVB-ASI or IP transport streams fed to the IRD-3101 can be demodulated and decoded to provide SD video with
embedded multi-channel audio, in all leading formats, as well as composite video and stereo analog audio for
monitoring. The IRD is also available with a DVB-CI slot, supporting leading Conditional Access Systems, and
allowing descrambling of multiple encrypted services. With its Gigabit Ethernet port, the IRD-3101 can also act as a
gateway, by performing IP encapsulation of the input transport stream in either RTP or UDP mode.
The IRD also provides optional video signal processing with frame synchronization and selectable delay as well as
proc-amp, up conversion and aspect ratio conversion. The IRD can decode an extensive range of Metadata, such as
CEA-608 compliant Closed captioning, Teletext, AFD, V-chip and DVITC Time Code, which can be embedded in the
decoded SDI signal. Transport Stream Metadata such as PSIP can also be analyzed.
The audio processing capabilities of the IRD-3101 are also extensive, with dual audio decoding and selectable stereo
downmix modes of decoded MPEG-1 and Dolby Digital (AC-3) 2.0 audio. Optionally, the IRD-3101 also performs
embedding of decoded of Dolby Digital (AC-3) 5.1 audio, with discrete 8-channel output.
In addition, the IRD-3101 performs a wide range of signal quality probing, with user-defined alarm settings on an
extensive range of transport stream parameters, including TR 101290 alarms, transport stream structure analysis and
individual program statistics.

2 Installation
2.1 Installation in the Densité frame
The IRD-3101 and its associated rear connector rear panel must be mounted in a Densité3frame. It is not necessary
to switch off the frame’s power when installing or removing the card. See the Densité3Frame manual for detailed
instructions for installing cards and their associated rear panels.
2.2 Rear Panels
The IRD-3101 has multiple inputs and outputs, and making space for all the necessary connectors at the rear of the
frame requires a double-width rear panel.
With the double-width rear panel installed, the IRD-3101 must be installed in the right-most of the two slots covered
by the panel in order to mate with the panel’s connectors.
NOTE: attempting to install the card in the wrong slot could result in damage to the edge connector of the
rear panel. BE CAREFUL
Figure 2.1 IRD-3101-3DRP Rear Panel for the IRD-3101
2.3 Connections
The rear panel connections are as follows:
•REF IN – External reference input
For external synchronization, connect a black studio reference signal to the BNC labeled REF IN.
The reference input must conform to SMPTE
170M/SMPTE 318M/ITU 624-4/BUT 470-6 for standard
definition signals and is used to phase the SD SDI outputs
to the studio.
The table shows the reference signals appropriate for the
supported input formats. In essence, the input and the
reference must have the same frame rate.
A reference mismatch will occur if there is a difference between the input video format’s frame rate and the
reference format’s frame rate.
When a mismatch occurs, an input error will be flagged and the card-edge Status LED will turn red to indicate
the mismatch.
•ASI IN 1 & 2 – Connect DVB-ASI signals conforming to EN 50083-9.
Supported input signals
Reference
525 (SMPTE-259M-C) NTSC (SMPTE-
170M)

GUIDE TO INSTALLATION AND OPERATION
IRD-3101 | 7
•ASI OUT – Outputs the selected input or DVB-CI
•HD/SD OUT 1 & 2 – SDI output, HD or SD
The IRD-3101 provides two identical HD/SD SDI video outputs on BNC connectors. The SDI video signals conform
to the SMPTE 292M and SMPTE 259M-C standards. HD signals are only available when the Up Conversion option
is activated.
•COMP OUT – down-converted and encoded composite output (requires Analog Output option)
This output is intended for monitoring only – it is not frame-synchronized, and the video has not been processed
through the post-processing blocks of the IRD-3101.
•Audio OUT (L & R) – analog audio extracted from the input signal (requires Analog Output option)
This audio is also embedded in the output video stream. If the input audio is 5.1, the user must select the two
source channels to monitor; otherwise, a downmix will be monitored. The analog audio output level is not adapted to
broadcast standard and is intended for monitoring of the signal only. Use the embedded audio or a level adapter for
broadcast applications
•ETH – Gigabit Ethernet – input and output share the same connector on the IRD-3101-3DRP panel
– the IRD-3101-3DRP-ECO ethernet change-over panel has two ETH connectors, labeled
1 and 2.
2.4 Installation of the Conditional Access Module (CAM)
The Conditional Access Module (CAM) is installed into the IRD-3101 via the front panel.
Depending on the conditional access system in use, the CAM may be in the form of a proprietary module, or in the
form of a carrier plus a smart card.
Both formats plug into the same receptacle on the IRD-3101.

3.1 Control options
The IRD-3101 can be controlled in two different ways:
•The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust
parameter values (see section 3.3).
•Miranda’s iControl system can be used to access the card’s operating parameters from a remote computer, using
a convenient graphical user interface (GUI). (see section 3.4)
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the IRD-3101, and is visible through the front access door
of the DENSITÉ frame. The chart shows how the various error conditions that can be flagged on the IRD-3101 affect
the LED status.
•If a cell in the chart is gray, the error condition cannot cause the LED to assume that status
•If more than one LED status is possible for a particular error condition, the status is configurable.
See Section 3.4.16 for details.
•The factory default status is shown by a , and forced status by an X
The LED will always show the most severe detected error status that it is configured to display, and in the chart error
severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

3.3 Local control using the Densité frame control panel
3.3.1 Overview
Push the SELECT button on the IRD-3101 card edge (Section 1.6) to assign the local control panel to operate the
IRD-3101. Use the control panel buttons to navigate through the menu, as described below.
All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all interaction
between the cards and the outside world. There are no operating controls located on the cards themselves. The
controller supports remote operation via its Ethernet ports, and local operation using its integrated control panel.
The local control panel is fastened to the controller card by a
hinged connector, and when installed is located in the front
center of the frame, positioned in front of the power supplies.
The panel consists of a display unit capable of displaying two
lines of text, each 16 characters in length, and five pushbuttons.
The panel is assigned to operate any card in the frame by
pushing the SELECT button on the front edge of that card.
•Pushing the CONTROLLER button on the control panel
selects the Controller card itself.
•The STATUS LED on the selected card flashes yellow.
The local control panel displays a menu that can be navigated
using the four pushbuttons located beneath the display. The functionality of the pushbuttons is as follows:
[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button once
enables modification of the value using the [+] and [–] buttons; a second push confirms the new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the
parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not
exit the menu system. To exit, re-push the [SELECT] button for the card being controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS LED reverts to its normal operating mode.
3.3.2 Menu for local control
The IRD-3101 has operating parameters that may be adjusted locally at the controller card interface.
•Press the SELECT button on the IRD-3101 front card edge to assign the Densité frame’s local control panel
to the IRD-3101
•Use the keys on the local control panel to step through the displayed menu to configure and adjust the IRD-

This panel allows selection of the source of signal for the
ASI output.
Use the pulldown to select between:
•Selected Input (on Input panel)
•DVB-CI (only if a conditional access module is
installed)
This panel only appears when a conditional access module
is installed. With no CA module, the ASI output always
follows the selected input.
3.4.5 The Decoder panel
The decoder panel gives the user the resources to select the
program that will be decoded by the IRD-3101
Config section:
Service Select – use the pulldown to select the service from
among those in the transport stream
A small lock icon to the left of the service number indicates
that the signal is encrypted.
Audio1 & Audio 2 – Use the pulldowns to select the audio 1
and 2 PIDs from the available channels.
NOTE that you can’t select the same PID for both audios
Clock Recovery – use the pulldown to configure clock
recovery. Options are:
•OFF – user the local clock. Preferred if there are many
errors in the stream or the IRD cannot lock easily
•From PCR -recover the clock from the PCR packet
Service Selection Mode – use the pulldown to choose how
