PRODUCT OVERVIEW
The BrightEye 71/71-F is a dual rate, eight channel audio embedder or disembedder for 1.5 Gb/s
high definition video signals or for 270 Mb/s standard definition signals. The analog audio ports
automatically configure for inputs or outputs when the module is configured for Mux or Demux.
Selection of Mux or Demux mode, audio group selection, VU status, and gain can be monitored and
adjusted from the front panel. More advanced functionality is available via the BrightEye Control
application.
The BrightEye 71/71-F includes an eight channel audio mixer with channel swap and shuffle capability
that allows you to completely rearrange and remix audio channels. It provides precise control over
audio level, up to 2 dB of gain to compensate for low level sources. All audio processing is performed
at full 24 bit resolution by a digital signal processor (DSP).
Delay is adjustable up to one second. The Data mode operation allows embedding or disembedding
of Dolby E or AC3 signals.
A glossary of commonly used video terms is provided at the end of this manual.
FUNCTIONAL DESCRIPTION
When configured as a multiplexer as shown in the functional block diagram below, the BrightEye
71/71-F has one serial digital video input and eight analog audio inputs. The audio streams are sample
rate converted (allowing the use of asynchronous audio) then processed in the input selector and
mixer/shuffler. The selected groups are then embedded into the video stream. The output of the
module is a digital stream that contains the original video signal and four audio pairs.
Optical Output with the 71-F
The BrightEye 71-F offers one optical output and one SDI output.

APPLICATIONS
The BrightEye 71/71-F is a highly versatile embedder/disembedder. Examples of possible BrightEye
71/71-F multiplex and demultiplex applications are given below.
Embedder (Mux) And Disembedder (Demux)
In this application, BrightEye 71/71-F can be used to multiplex video and audio together to feed a
video server. The output from the video server can then be fed to another BrightEye 71/71-F where the
audio can then be demultiplexed for another application.

REAR CONNECTORS
All connections to the BrightEye 71/71-F are made on the rear of the unit. Refer to the illustration and
detailed explanations below for a reference of the rear connectors.
Power Connection
Connect the modular power supply to the 12-volt DC power input connection on the far left of the
unit. Use the locking ring to secure it. If you don’t have the power supply already, contact Ensemble
Designs to purchase one.
USB Connector
Connect the USB port to a PC or Mac running BrightEye software for more comprehensive control,
diagnostics, and upgrades to the unit. BrightEye PC/Mac Control application software is included on
the CD that came with your unit, or the application can be downloaded here:
http://www.ensembledesigns.com/support/brighteye-support/
HD/SD SDI Out
This output is a digital stream that contains the original video signal.
When the module is configured as a multiplexer, the four Phoenix connectors are configured as inputs.
This external audio is multiplexed into the SDI output as desired.
When the module is configured as a demultiplexer, this output contains the original video and the
original embedded audio. The audio signals present in this incoming video signal are extracted and
delivered as outputs on the analog audio Phoenix connectors.
Analog Audio Connectors
The four Phoenix connectors are either analog audio inputs or outputs depending on how the unit is
configured (Mux or Demux). Each connector inputs or outputs 2 channels of audio (1 pair.) When the
unit is configured as Mux, the four Phoenix connectors are inputs. When configured as Demux, the
four Phoenix connectors are outputs.
HD/SD SDI In
This BNC input accepts an HD or SD SDI serial digital video signal with or without embedded audio.
When the module is configured as a demultiplexer, embedded audio present on this input stream can
be extracted, processed on the module, then output from the module on the audio outputs.
When configured as a multiplexer, external analog audio can be inserted into the SDI input stream or
replace existing embedded audio.

OPERATION
Control and operation of the BrightEye 71/71-F is performed from the front panel or with the BrightEye
Control application. When controlling the module from the front panel, most, but not all of the control
settings and parameter choices will be available. For more comprehensive control, use the BrightEye
PC or Mac Control application.
Front Panel Controls and Indicators
The front panel shown in the figure below provides status indicators and control over module setup.
Status Indicators
The following status indicators are provided on the front panel:
• In – Illuminates green when a valid input is present on the SDI In connector.
• Mode – The currently selected mode (Mux or Demux) illuminates green.
• Group – The audio group (1, 2, 3, or 4) currently targeted for embedding or disembedding
(depending on module configuration) illuminates green when the selected group contains
audio, and illuminates red when the selected group does not contain audio.
• Gain – These controls allow for quick adjustment of Gain level for the four channel pairs.
Gain adjustment is done in conjunction with the VU indicators. For independent channel
adjustment, and other controls, use the BrightEye Control application.
• VU – VU output level and the status of the Gain adjustment for each channel pair is indicated
by the state of the VU and Gain indicators for each of the channel pairs. The VU indicator
illuminates red when the audio level exceeds the headroom level set by the user (with the
Peak Indicator control in the BrightEye Control application).
Additionally, the VU indicator illuminates orange when the output is above 0 VU, illuminates
green when the output is above -20 VU, and doesn’t illuminate when the output is below
-20 VU. The Gain indicator illuminates red when the gain level has been adjusted to a value
other than unity by the user. The 0 VU point corresponds in the digital domain to the digital
reference level (-18 or -20 dBFS).
• Mon Vol (Monitor Volume) – Illuminates green when monitor volume is set to unity, or red
when set to other than unity.
• Pwr (Power) – Illuminates green when the BrightEye unit has power and the internal voltage
regulator is functioning correctly.

ADJUSTMENTS
Adjusting Parameters from the Front Panel
From the front panel, use the Mode, Left Arrow, and Right Arrow buttons to select and adjust
parameters.
Pressing the Mode button cycles through the parameters that can be modified from the front panel.
The LED of the currently selected parameter will blink. A quick press of the Mode button advances to
the next editable parameter. A longer press of the Mode button will back up to the previous editable
parameter.
Pressing the Right Arrow or Left Arrow advances or backs up through the choices for the currently
selected parameter, or increases (Right Arrow) or decreases (Left Arrow) the value of the selected
parameter.
The LED of an edited parameter will blink for 15 seconds, after which time its value is stored in
memory. If power is interrupted before this 15 second timeout period has elapsed, the edited state will
not be not saved.
Pressing the Right Arrow and Left Arrow simultaneously restores the selected parameter to its
default value.
The controls and their indicators are described below:
Mode – This control selects the Mux behavior with the following choices:
• Mux – Embed audio into the SDI signal, replacing the existing embedded content or
cascading (augmenting the existing embedded content).
• Demux – Disembed audio that is in the SDI signal.
Group Select – This control selects the audio group for embedding or disembedding with the
following choices:
• 1 – Audio Group 1, 2 – Audio Group 2, 3 – Audio Group, 4 – Audio Group 4
Ch 1/2, Ch 3/4, Ch 5/6, and Ch 7/8 Gain Adjustment Indicators –
These controls allow for quick adjustment of Gain level for these two channel pairs. For independent
channel adjustment, and other controls, use the BrightEye PC or BrightEye Mac application.
Ch 1/2, Ch 3/4, Ch 5/6, and Ch 7/8 VU Indicators –
These indicators provide information about the level of the analog outputs on these channels. More
detailed indicators are available through the BrightEye Control application.
