BrightEye 11 SDI to Analog Converter
PRODUCT OVERVIEW
BrightEye™ 11 provides digital to analog conversion with the full range of analog
output formats available: Beta, SMPTE, RGB, and Composite (with simultaneous
S-Video Y/C outputs). 12 bit processing and conversion at 8x oversampling mean
the best looking images possible.
Output format and gain are controlled from the front panel. The BrightEye
Control application also provides remote control of the unit from a personal
computer with USB support. A status display on the front panel indicates input
presence.
BrightEye 11 is the perfect choice to feed monitors, VTRs, or video projectors.
A glossary of commonly used video terms is provided at the end of this user guide.
FUNCTIONAL DESCRIPTION
As shown in the functional block diagram below, serial digital video is fed to the
converter on a single BNC connector.
The SDI input is routed directly to the SDI Out BNC and the reclocking and deserializing circuitry before entering the D to A converter.
The converted analog signal is then encoded to the desired output format as
chosen on the front panel or with BrightEye PC or Mac. During this stage, gain
can be adjusted for the correct output levels.
BrightEye 11 is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage between 90 and 230 volts, at 50 or 60 Hertz. It
uses a standard IEC line cord and can be used anywhere in the world. It is
normal for the converter to be quite warm to the touch when operating.

APPLICATIONS
The versatility of BrightEye 11 can be utilized in a number of different applications where conversion of SDI to analog video is required. Some examples of
using BrightEye 11 are given below.
Electrical Conversion with Analog Monitoring
This application, shown in the illustration below, utilizes the full functionality of
BrightEye 11 by using the SDI output to feed a destination such as a video router
while monitoring the signal on an RGB monitor at the same time.
Analog Monitoring of an SDI Signal
This application performs conversion of an SDI signal from a production switcher
to the Composite/S-Video Y/C format for feeding an S-VHS tape machine while
monitoring the signal on a composite analog monitor as shown below.

REAR CONNECTORS
All connections to the BrightEye 11 converter are made on the rear of the unit.
Refer to the illustration below.
Power Connection
Connect a 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.
USB Connector
The USB connector is used to provide more comprehensive control, diagnostics,
and upgrades to the unit from a PC or Mac. Use the BrightEye Control application included on CD-ROM to make adjustments as described in the OPERATION
section of this user guide.
Input/Output BNCS
There are five rear BNC connectors which are used as inputs and outputs as
follows:
SDI In
This BNC input accepts a SMPTE 259M serial digital component signal, 525 or
625 line standard.
SDI Out
The Serial Digital Component signal from the reclocking circuitry is presented on
this connector. This output conforms to the ITU-R 601 standard for serial digital
video, with SMPTE 259M serialization at 270 Mb/s.
