Revision 1.3 SW v1.2.1

By Engineers, For Engineers
In 1989, a former television station engineer who loved
designing and building video equipment, decided to
start a new company. He relished the idea of taking
an existing group of equipment and adding a few
special pieces in order to create an even more elegant
ensemble. So, he designed and built his first product and
the company was born.
Focused On What You Need
As the company has grown, more former TV station
engineers have joined Ensemble Designs and this wealth
of practical experience fuels the company’s innovation.
Everyone at the company is focused on providing the
very equipment you need to complete your ensemble
of video and audio gear. We offer those special pieces
that tie everything together so that when combined, the
whole ensemble is exactly what you need.
Notably Great Service for You
We listen to you – just tell us what you need and we’ll
do our best to build it. We are completely focused on
you and the equipment you need. Being privately held
means we don’t have to worry about a big board of
directors or anything else that might take attention away
from real business. And, you can be sure that when you
call a real person will answer the phone. We love this
business and we’re here to stay.
Bricks and Mortar of Your Facility
The bricks and mortar of a facility include pieces like
up/downconverters, audio embedders, video converters,
routers, protection switches and SPGs for SD, HD and
3 Gb/s. That’s what we’re focused on, that’s all we do
– we make proven and reliable signal processing and
infrastructure gear for broadcasters worldwide, for you.

Clearly, Ensemble wants to be in the broadcast equipment business. It’s so rare anymore to nd a company of this
caliber that has not been gobbled up by a large corporation. They are privately held so they don’t have to please the
money people. They really put their eorts into building products and working with customers.
I’m really happy with the BrightEye products and Ensemble’s service, and even more important my engineers are
happy. We’ve continued to upgrade the product and add more cards. We will be rebuilding our production control
room and we will use BrightEye again.

Product Overview
Sync Generator and Test Signal Generator
The BrightEye 56 is a genlockable sync generator and test signal generator that can be used as either
a slave or master reference generator. It can lock to house reference or it can lock to its own internal
precision standard. BrightEye 56 is well suited for remote trucks, post, helicopters and fly packs.
Outputs
The SDI Outputs 1 and 2 provide 1.5 Gb/s HD or SD SDI test signals or black with embedded audio.
There are also outputs for Composite, Tri Level Sync and AES digital audio. There are three user-
programmable outputs that are selectable between AES, LTC, Word clock or 6 Hz Pulse. Analog audio
and AES outputs provide tone or silence.
The SDI and analog composite outputs provide simultaneously available signals including Color Black,
Bars, Crosshatch, Multi-burst, and SDI Checkfield (Pathogenic). The Cyclops feature adds a motion
element to the selected video test signal. An ID slate with user-programmable text can overlay the test
pattern.
Adjustments and Controls
Many controls can be adjusted through the intuitive front panel. Additionally, BrightEye Mac and
BrightEye PC software provides a complete user interface for all adjustments and controls. Please note
that BrightEye Mac or BrightEye PC version 2.0 or later is required.
Tri Level Sync
Tri Level Sync offers improved timing accuracy over traditional Bi-Level Sync. The analog output of a
standard sync generator is Bi-Level Sync. The timing reference is the 50% point of the leading edge.
The relative timing of this point shifts with changes in gain, DC reference, and frequency response.
The timing reference in Tri Level Sync is also at the 50% point of the sync pulse, but because this pulse
has both the positive and negative excursions, this point is the same as the DC ground reference. This
symmetry makes the signal virtually immune to time shift from gain, DC and response errors. The zero
point never drifts. The zero crossing is easy to detect every time which ensures timing accuracy.
The Tri Level Sync Generator block is configured in the BrightEye Control application to one of four HD
formats (1080i, 1080p, 720p, or 1080sF). The Tri Level Sync output frame rate can be selected between
23.98/50/59.94, the most commonly used family of frame rates, and 24/30/60, reserved for use with
special applications such as film.

The BrightEye 56 will apply the selected TLS frame rates to specific formats and line rates as shown in
the table below.
Frame Rate 23.98/50/59.94 Hz 24/30/60 Hz
Line Rate NTSC PAL NTSC PAL
1080i 59.94 50 60 50
720p 59.94 50 60 50
1080p 23.98 25 24 25
1080sF 23.98 25 24 25
Tone Generator Locked to Master Clock or External Reference
The Tone Generator is also locked to the master clock or the external reference, so the 48 kHz AES
output will be synchronous to the video outputs. In NTSC there are exactly 8008 audio samples in
every five video frames. There will be exactly 1920 audio samples in every PAL video frame.
Configurable Tone Generator
The Tone Generator can be configured for silence, a continuous tone, or an interrupted tone which is
coordinated with the Cyclops moving element. The Tone Generator feeds the Analog Audio outputs
through a precision digital-to-analog converter. It feeds an AES formatter to produce a standard AES
output. And finally, it is fed to an embedder (audio inserter) so that it will also be a part of the SDI
outputs.
Internal Timecode Generator
The internal Timecode Generator feeds DVITC on the SDI outputs and VITC on the composite outputs.
Timecode can also be selected in LTC form on the programmable Aux 1, Aux 2, and Aux 3 outputs.

Functional Description
External House Reference or Internal Precision Standard Reference
The BrightEye 56 can lock to an external house reference or it can lock to its own internal precision
standard reference.
The Ref In BNC on the rear of the unit will accept 1 V P-P PAL, NTSC, 10 MHz or Tri Level Sync as a
reference. The outputs will all be synchronous relative to this reference. The overall vertical and
horizontal timing of the outputs can be adjusted in the BrightEye PC or Mac Timing menu. Reference
status is reported on the front of the unit and in BrightEye PC or Mac. The Composite video output will
have the same ScH phase (or color framing) as the external reference.
A special case exists when simultaneously using PAL and NTSC. If the output standard for the module
is PAL and an NTSC reference is connected, BrightEye 56 will lock to the reference at the fundamental
clock frequency common to PAL and NTSC. This is referred to as “clock-locked”. There is no horizontal
and vertical relationship but BrightEye 56 will have the same frequency accuracy as the reference. The
AES audio output will be synchronous simultaneously to the BrightEye 56 PAL output and the NTSC
reference. The same case is true for an NTSC standard with a PAL reference.
Temperature Compensated Oscillator
When no external reference is connected to the unit, the fundamental clock source for BrightEye 56
is taken from a temperature compensated oscillator which guarantees frequency accuracy to within
1 cycle of subcarrier (better than 0.2 ppm) across the full operating temperature range. In addition,
because it does not require a crystal oven, BrightEye 56 is accurate immediately upon power up. This
ensures that the BrightEye 56 outputs meet the most stringent standards.

Time Code Generator
The output of the BrightEye 56’s Timecode Generator is available simultaneously in multiple output
types through multiple output connectors as shown in the Timecode Output Types and Output
Connectors table on the next page.
The Timecode Generator will always run at the same frame rate as the main SDI outputs. If that output
is in the NTSC family (29.97 or 59.94), you can configure for the choice of Drop Frame or non-Drop
Frame operation. Drop Frame is necessary if you want the timecode value to track the actual time of
day. By dropping specific frames, it makes up for the fact that the frame rate is just shy (by 1/1.001) of
60 Hz.
You can load the Timecode Generator with a preset value through the control system. When a
BrightEye 56 powers up, the Timecode Generator starts at 0:0:0:0. Alternatively, the BrightEye 56
can read VITC present on the reference input. This timecode value will be used continuously by the
BrightEye 56’s internal generator. When this option is selected, the timecode presented on the many
different outputs will all match the timecode on the reference input.
Outputting Timecode
The BrightEye 56 has one timecode generator. The timecode that it produces can be output through a
number of methods:
1. Routing LTC (linear timecode) to one of the Programmable Output BNCs (Aux 1, Aux 2, Aux 3). This
is an analog, unbalanced, single-ended 1V P-P signal at 75 Ohm impedance.
2. Routing LTC to the Analog Audio Output connector. This will be exactly the same signal as when it
is routed to a BNC, but it will be a differential (balanced) twisted pair analog signal coming out of
the green Phoenix connector on the rear of the unit. Choose Timecode LTC on one of the 16 audio
channel selectors, then route that audio to the Analog Audio Output connector.
3. Routing LTC as an audio channel in an AES bitstream. Choose Timecode LTC on one of the audio
channel selectors, then select AES on any of the Programmable Outputs (Aux 1, Aux 2, Aux 3).
There are 9 different AES choices which correspond to channel pairs 1/2, 3/4, 5/6, etc, and the
choice of AES Silence. Choose the appropriate audio pair so that the particular AES stream being
fed to an output includes the timecode signal.
4. Routing LTC as one of the audio signals embedded in the SDI Output stream.
5. Routing VITC (vertical interval timecode) on an analog composite output.
6. Routing DVITC (digital vertical interval timecode) on an SD SDI output.
7. Routing ATC (ancillary timecode) on an HD SDI output.
You can output an analog timecode signal with any of the methods described above. The difference
between them is a choice between balanced or unbalanced. If you need to feed timecode to a device
with an XLR input, you would generally want to use the balanced output. However, it is also possible
to use the unbalanced output through Programmable Outputs (Aux 1, Aux 2, Aux 3) and connect it to
the destination with a balancing transformer. This would be much like the DATS adaptors for AES.
The advantage of using the unbalanced output through the Programmable Outputs (Aux 1, Aux 2,
Aux 3) is that you can run it through a BrightEye 41 Distribution Amplifier to make more copies.

Audio Generation and Routing
Audio Generators
The diagram shown on the following two pages depicts the audio signal generation and routing for
the BrightEye 56. It appears twice, first in a portrait view, then larger as a landscape view.
Audio can be output as follows:
• Analog audio (one stereo pair)
• AES digital audio (BNC)
• Digital audio embedded in the SD SDI and/or HD SDI video outputs
Sixteen Independently Programmable Audio Channels
The BrightEye 56 supports sixteen audio channels and the content of each channel is independently
programmable. Choices include adjustable frequency tone generators, tone sweeps, silence, timecode,
and the external AES input. Left/right channel ID that synchronizes to the cyclops feature can also be
selected.
Audio Embedded in the SDI Outputs
All sixteen of these channels can be embedded in the SDI outputs. Each AES output can select from
any of the eight pairs that make up these sixteen channels. Similarly, the stereo analog output can be
driven from any of these audio signal pairs.
Support for Analog and Digital Audio
The AES digital audio outputs are always synchronous with all of the video outputs – regardless
of format – because all of the video outputs can be locked to a common time base. Multiple tone
generators can be used to identify multi-channel content. Analog audio is output as one stereo pair or
as two mono channels.

Genlocked Test Signals
BrightEye 56 can be used to provide bars and other test signals to facility devices timed to the same
house reference. A number of test signals can be fed to a router, switcher, and other devices in a facility
where genlocked timing is important.
As shown in the example below, a BrightEye 56 is fed with the house reference to the Ref In BNC. The
audio tone can be embedded into the SDI timed test signal output and fed to an HD or SD SDI router
and switcher. This allows each of the test signals to be in time with the signals fed to the other devices.
