BrightEye 72
PRODUCT OVERVIEW AND FUNCTIONAL DESCRIPTION
The BrightEye 72 turns any High Denition Multimedia Interface (HDMI) display into a monitoring
solution with professional monitoring features. With the BrightEye 72, you can monitor any type of
digital video signal, including 3 Gb/s signals.
Use with any HDMI Monitor
The BrightEye 72 can be used with any HDMI monitor. Because there is a wide range of HDMI monitors
available, you have a lot of choices when it comes to selecting which particular HDMI monitor you
want to use.
SDI Input
The BrightEye 72 has an SDI input and a reclocked loopback SDI output. The input can be 1.5 or
3 Gb/s HD SDI or SD SDI. The loopback SDI output is a copy of the SDI input. The key features, such as
on-screen display of audio and open captions, are output through the HDMI output.
Test Signal Generator
The built-in test signal generator, useful for troubleshooting, inserts the signal at the front of the
signal path, so its behavior is functionally the same as cabling a test signal generator into a BNC input.
This path is fully adjustable so that you can compensate for the performance of the particular HDMI
monitor to which the BrightEye 72 is connected.
The test signal generator provides several test patterns including SMPTE bars with PLUGE, which is
useful for monitor alignment.
Video Proc Amp and Color Corrector
The Proc Amp and Color Corrector functions provide precise control over the output video levels. A
variety of controls are provided for making exact adjustments to produce correct luminance and color
rendition on the monitor and can be used with the built-in test signals. Adjustments are performed at
full 10-bit SDI resolution.

Audio Metering Overlay and Disembedding
The BrightEye 72 has a sophisticated audio metering overlay capability that
uses four groups of four-channel on-screen VU meters. It includes a hanging
peak level indicator and a user-adjustable peak (headroom) indicator. You can
disembed and visually monitor up to sixteen channels of audio. Up to eight
channels of audio can be passed through the HDMI output.
HDMI monitor output example illustrating audio metering overlay, graticule overlay, closed caption
decoding, and timecode reader.
Graticule Overlay
A built-in graticule generator puts up Safe Title and Safe Action reference markers as well as SD Safe
markers on HD signals. There are thin lines running from top to bottom that indicate the SD protect
area. These graticule reference markers aid in seeing how content is aligned, facilitating lm transfer,
post production and quality control measurements relating to picture location for both the 4:3 and
16:9 aspect ratios. Safe Title displays the safe title boxes. SD Protect Only displays only the SD Protect
area without displaying the safe title boxes. You can adjust the color and intensity of the graticules or
turn graticules o.

BrightEye 72
Closed Caption Decoding
The BrightEye 72 has a caption reader in the video path that decodes caption data. After being
decoded, a character generator system in the BrightEye 72 overlays the captions onto the video
which is then sent through the HDMI output to be displayed on screen. This is useful for compliance
monitoring to be sure that all the captions are present in the broadcast signal.
The CEA-608 and CEA-708 standards for closed captions are specic to NTSC-based television systems.
Accordingly, they are supported for these input signals:
Standard Denition 525/59.94
High Denition 1080i/59.94
High Denition 720p/59.94
Under U.S. federal law, all consumer television receivers above a certain display size sold in the U.S.
must include decoding and display of closed caption data. However, that requirement is only for
over the air (or cable) broadcast signals received through the tuner input. The HDMI input of these
displays is not required to support closed captions. In fact, the HDMI standard provides no support for
captions in ‘closed’ form. BrightEye 72 is able to deliver open captions to an HDMI display by rendering
them as actual image content with its built-in character generator.
Timecode Reader
The video path includes a timecode reader. BrightEye 72 can read and
display running timecode from either DVITC (Digital Vertical Interval
Time Code) on SD SDI inputs, or ATC (Ancillary Time Code) on
HD SDI inputs. Timecode display

Horizontal and Vertical Shift
The BrightEye 72 can shift images horizontally and/or vertically to enable inspection of content in the
horizontal and vertical intervals outside of the picture itself, such as embedded audio, closed caption
data blocks, and blanking edges of the signal.
HDMI monitor output example illustrating Horizontal shift. H and V shift enables inspection of content in
the horizontal and vertical intervals.

APPLICATIONS
Use BrightEye 72 with any HDMI monitor in broadcast production and distribution, QC, engineering,
post production, and the control room. In addition to video, you can also monitor ancillary data such
as closed captions, timecode, and audio. Graticules are available to align titles. Use the BrightEye 72 in
studio applications where you need to adjust the color temperature of on-set monitors so they look
right on camera.
The BrightEye 72 converts 3G/HD/SD SDI video signals to HDMI to provide professional monitoring
capabilities using an HDMI display. In the example below, the program feed from a server goes into
the SDI Input BNC connector of the BrightEye 72 and loops back out through the 3G/HD/SD SDI
Output BNC connector to the router. The input SDI signal is converted to HDMI and sent out through
the HDMI Out connector to an HDMI monitor.

HDMI Out
The High Denition Multimedia Interface (HDMI) is an uncompressed, all-digital interface that
transmits digital video and eight channels of digital audio. HDMI is a bit-serial interface that carries
the video content in digital component form over multiple twisted-pairs. The HDMI interface standard
supports limited cable length as compared to SD and HD SDI. The use of cables over 10m (30 feet) is
not recommended. Connect the HDMI output to your video monitor.
Audio Out
The Audio Out connector provides two channels of balanced analog audio. This connector is tted
with a pluggable terminal block that accepts bare wire leads. Wires can be inserted into the small
round holes. Depress the orange tab to release them.
Follow the legend to connect the Ground (G), Positive (+), and Negative (-) connections for each signal.
Ch 1 corresponds to the left channel in a stereo system, and Ch 2 corresponds to the right channel.
If connecting to an unbalanced (single-ended) destination, such as a consumer speaker amplier, with
shielded coaxial style audio cable, connect the center conductor to the Positive (+) terminal. Then
connect the outer conductor to both the Ground (G) and Negative (-) terminals. Analog reference
levels can be congured from the BrightEye Control application.

BrightEye 72
The VU LED indicates the output audio level of the sum of channels 1 and 2. The LED will be
green when the audio level is at or below the digital reference level. The LED lights yellow
when the audio level is between the digital reference level and the peak threshold. The LED
lights red when the peak threshold is reached. Note that the digital reference level (sometimes
referred to as 0 VU) may be set by the user to -20 dBFS or -18 dBFS. Similarly, the user may set
the peak headroom between -2 dBFS and -10 dBFS. These two parameters are adjustable using
the BrightEye PC or Mac Control application.
Pwr (Power)• – Illuminates green when the BrightEye unit has power and the internal voltage
