GUIDE TO INSTALLATION AND OPERATION

1 IRD-3802 HD/SD MPEG Decoder with ASI and GigE IP inputs

1.1 Introduction

The IRD-3802 combines MPEG-2 and H.264 decoding of ASI and IP transport streams to either HD or SD,
with processing of key video and audio parameters and signal probing functions for feed agg regatio n,
distribution, and monitoring applications by broadcasters and TV services providers.

DVB-ASI or IP transport streams fed to the IRD-3802 can be decoded to provide either HD or SD SDI video
with embedded multi-channel audio, in all leading formats, as well as composite video and stereo analog
audio for monitoring. With its Gigabit Ethernet port, the IRD-3802 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 convenient optional high video signal processing with frame synchronization and
selectable delay as well as Up/Down/Cross conversion and aspect ratio conversi on. The IRD can decode an
extensive range of metadata, such as CEA-608 compliant Closed Captioning, AFD, V-chip and DVITC time
code, that 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-3802 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-3802 also performs decoding of Dolby Digital (AC-3) 5.1 audio, with discrete 6-channel output.

In addition, the IRD-3802 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.

2.1 Unpacking

Make sure the following items have been shipped with your IRD-3802. If any of the following items are
missing, contact your distributor or Miranda Technologies Inc.

• IRD-3802 Integrated Receiver and Decoder

• IRD-3802-3DRP Rear Panel (see figure 2.1)

2.2 Installation in the Densité frame

The IRD-3802 and its associated rear connector rear panel must be mounted in a Densité3 frame. It is not

3

necessary to switch off the frame’s power when installing or removing the card. See the Densité
manual for detailed instructions for installing cards and their associated rear panels.

2.3 Rear Panels

The IRD-3802 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-3802 must be installed in the right-most of the two slots
covered by the panel in order to mate with the panel’s connectors.

Frame

If it is placed in the wrong slot, the front panel LED will flash red. Move the card to other slot for correct
operation. No damage will result to the card should this occur.

Figure 2.1 IRD-3802-3DRP Rear Panel for the IRD-3802

IRD-3802 | 9

GUIDE TO INSTALLATION AND OPERATION

2.4 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 SMPTE 274M /
SMPTE 296M for high definition signals and is
used to phase the HD/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 – ASI video (2)
Connect up to two DVB-ASI signals conforming to EN 50083-9. The IRD-3802 can automatically switch to

the detected input.

• ASI OUT – Outputs the selected ASI or de-encapsulated IP input

• HD/SD OUT 1 & 2 – SDI output, HD or SD

The IRD-3802 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. The output format follows the input format.

• COMP OUT – down-converted and encoded composite output (requires Analog Output option)
This output is not frame-synchronized, and the video has not been processed through the post-processing

blocks of the IRD-3802.

• 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.

3 Operation

3.1 Control options

The IRD-3802 can be controlled in two different ways:

• The local control panel and its push-buttons can be u sed 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 operati ng 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-3802, 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-3802 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 3.4.12 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.

GUIDE TO INSTALLATION AND OPERATION

3.3 Local control using the Densité frame control panel

3.3.1 Overview

Push the SELECT button on the IRD-3802 card edge (Section 1.5) to assign the local control panel to
operate the IRD-3802. 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 handl es 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 select s 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.
