BrightEye 54 Sync Generator and Test Signal Generator
BrightEye 54 - Page 2
PRODUCT OVERVIEW
BrightEye 54 is a master sync generator and test signal generator that is perfect
as a master reference generator for remote trucks, desktop, and fly packs. It is a
stable timing source, operating from an internal precision standard that meets
full broadcast specifications.
Front panel controls select between NTSC and PAL standards, choose video
patterns, toggle the identification slate, toggle audio tone, and select HD Tri Level
Sync format. The BrightEye Control application is provided to allow more detailed
control of the unit from a PC with USB support.
SDI (serial digital component) video, analog composite video, AES audio, analog
audio, and HD Tri Level Sync are all generated simultaneously.
Aglossary of commonly used video terms is provided at the end of this manual.
FUNCTIONAL DESCRIPTION
The fundamental clock source for BrightEye 54 is 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 54 is accurate to frequency
immediately when powered up. This ensures that the BrightEye 54 outputs meet
the most stringent standards.
This master clock drives the Sync Gen block. As user configured for 525 (NTSC)
or 625 (PAL) line rates, standard definition output feeds horizontal and vertical
sync to the internal Test Signal Generator.
The HD Tri Level Sync Gen block is further user configured in BrightEye PC or
Mac to one of four HD formats (1080i, 1080p, 720p, or 1080sF). The Tri Level
Sync output frame rate can be selected from two choices in BrightEye PC or Mac,
23.98/50/59.94, the most commonly used, and 24/30/60, a frame rate reserved for
use with special applications such as film.
The module will apply the selected TLS frame rates to specific formats and line
rates as shown in the table below.
The Sync Gen section also has an output which indicates coincidence between the
vertical intervals of the SD and HD outputs. In all formats except 1080sF/23.98,
the vertical intervals will be coincidental in every field or frame. In 1080sF/23.98
that coincidence occurs once for every 4 sF frames and every 5 SD (NTSC) frames.
Accordingly, this coincidence marker occurs at a 6 Hertz rate, and is commonly
referred to as a 6 Hz pulse.

The digital Tone Generator is also locked to the master clock, so the 48 KHz AES
output will be synchronous to the video outputs. In NTSC there are exactly 8008
audio samples in every 5 video frames. There will be exactly 1920 audio samples
in every PAL video frame.
The Tone Generator can be configured for a 1.0 KHz continuous tone, or an
interrupted tone which is coordinated with the Cyclops moving element. The
Ton e Ge ne ra to r fee ds th e A na lo g A ud io o ut pu ts th ro ug h a pr ec is io n di gi ta l to
analog converter. It feeds an AES formatter to produce a standard AES output.
And finally, it is fed to an audio embedder so that it’s present in the SDI output.
The user selected test signal is produced in the Test Signal Gen block. The test
signal then passes to the Slate ID Text Generator which can overlay a line of user
programmable text across the test pattern. This block also has the Cyclops
Motion Marker which adds a moving element to the image.
This video signal is combined with the output of the Tone Generator to produce a
serial digital (SDI) output.
The same video signal is digitally encoded to composite video and converted to
analog form to drive the Analog Composite output.
BrightEye 54 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 warm to the touch when operating.

APPLICATIONS
BrightEye 54’s small size and complete feature set make it a versatile sync and
test signal generator. Some examples of possible BrightEye 54 applications are
given below.
Desktop Application
BrightEye 54 is convenient for desktop and non-linear editing applications since
it can provide reference for all types of VTRs and provides test signals as well.
Truck/OB Van and Fly Pack
BrightEye 54’s variety of video and audio outputs combined with its small size
make it particularly useful for mobile applications. It can provide reference or
test signals for any type of equipment making it a great asset in the dynamic
applications found in mobile use.
