DVI/VGA to 3G/HD/SD Scan Converter User Guide
PRODUCT OVERVIEW
BrightEye Mitto™ is a high performance scan converter that converts DVI or VGA to SD, HD, 3 Gb/s and
composite video.
For broadcasters and video professionals who rely on video content from the web, BrightEye Mitto™
oers the best way to take computer video to air. Mitto provides a way to use YouTube™ material in
a news broadcast, show nancial data from a web site on a TV program, display viewer emails on a
morning talk show, or take radar information from a computer into a master control switcher for on-air
use.
Exclusive Filtering and Scaling Technology
A superior quality scan converter, BrightEye Mitto™ has the advantage of proprietary scaling
technology and exclusive multi-tap ltering. The region you select for output determines if Mitto acts
as an upconverter or downconverter. The lters automatically adjust according to the conversion
being performed.
Bringing progressive images from the desktop into the interlaced world of video used to be a
compromise between sharp details versus intereld icker. Mitto’s advanced ltering satises both of
these requirements. The result is that the output looks as good, or better, than the original and passes
the most stringent testing.
Digital and Analog Video and Audio
The intuitive front panel interface makes it easy to choose the desired video output format. Choices
are 1.5 and 3 Gb/s HD SDI and SD SDI. When the digital output is SD SDI, analog composite video is
output on a separate BNC. The genlock reference input allows the video output to be timed to house.
The audio input accepts either AES digital audio or analog audio. Audio is embedded into the SDI
outputs which is useful for integration with video servers and routers.
Easy to Use
BrightEye Mitto™ is easy to use, both from the software interface and the front panel. All the control
you need is available from the front panel. Screen selection, video format, timing and many of the
other controls can be accessed with push buttons from the Mitto front panel.
The included BrightEye Mac/PC control application provides an additional level of control. It allows
you to use your mouse to click and drag over the specic portion of computer video that you want
to output. This lets you see the parts of the screen you don’t want to output, as well as the parts you
do want to use. The perspective of seeing the whole screen gives you the ability to choose exactly
which portion of the video you want to output. Whether you output the entire screen of just a selected
portion, you will be able to see exactly what you are doing. Presets enable you to store your favorite
settings. The BrightEye Mac/PC control software is not required, but it does oer a very handy user-
interface.

FUNCTIONAL DESCRIPTION
Video
The BrightEye Mitto™ is a scan converter with a DVI/VGA input. Its output options are SD (standard
denition), HD (high denition), and 3G (high denition).
In a typical application, Mitto sits between the computer and the computer monitor. The computer
feeds the DVI-I input. The Mitto DVI-I Loop Out feeds the computer monitor. The maximum resolution
supported is 1920 by 1200 which is excellent for HD applications.
Mitto’s DVI/VGA Input and the DVI/VGA Loop Out use DVI-I (integrated) connectors which provide
both digital and analog connectivity. The larger group of pins are digital while the four pins on the
right are analog. Included with every Mitto are two 15-pin, VGA-to-DVI adapters for use in legacy
installations.
SDI Out 1 and 2 BNCs output SD SDI, 1.5 Gb/s HD SDI, or 3 Gb/s HD SDI video. The output only
includes the portion of the computer screen that you have selected with Mitto. Mitto upconverts or
downconverts the signal depending on how much of the computer video you select and the output
standard you select.
The Composite Out BNC provides composite video out when SD is selected on the SDI outputs. If HD
is selected on the SDI outputs then the composite out BNC outputs black. Alternately, the Composite
Out BNC can be set to output AES audio with a control in BrightEye PC/Mac software.
Audio
Mitto has four audio sources to draw from: analog audio in, AES audio in, audio coming in along with
an HDMI input, and an internal tone generator.
AES digital audio or analog audio can be fed from the computer’s headphone out or line out into
Mitto’s audio input. The audio input is an 1/8 inch stereo mini-jack that goes to a stereo analog-to-
digital converter with two AES receivers which are followed by two sample rate converters. Two
channels of analog audio or four channels (two streams) of AES digital audio are supported on this
input.
If an HDMI input is used, 8 channels of embedded audio may be present.
There is also a tone generator. When Mitto’s internal color bars are turned on, there will be bars and
tone on the output.
The built-in audio mixer provides for level adjustment, channel tie, and output assignment controls
for up to four channels of output. If you use the audio control on Mitto’s front panel, the slider controls
Free Software Upgrades
BrightEye Mitto’s software is easily upgraded through the unit’s USB port. Software upgrades are
available for no charge for the life of the product and are conveniently downloadable from the
Ensemble Designs web site.
Every unit comes with a ve-year warranty.

will automatically tie together.
The audio appears in the embedded SDI outputs and, if desired, can also be output as AES on the
Composite Out BNC.
RS-232 and GPI Control
Mitto’s RS -232/GPI port can be used with third-party control and automation systems. GPI and RS-232
are supported simultaneously. Additionally, the Ensemble Designs Avenue GPI control panel (part
number XYCP) can be used with BrightEye Mitto™.

BrightEye Mitto™, select the highest available resolution on the computer. For HD applications,
1920x1200 or 1920x1080 is preferred. Alternately, you could choose 1024x768. 1920x1200 is the
maximum resolution that Mitto accepts.

www.ensembledesigns.com BrightEye Mitto - Page 14
DVI/VGA to 3G/HD/SD Scan Converter User Guide
When using VGA
When a VGA signal is fed to Mitto, you must choose a VGA resolution using the VGA Resolution control
from the Input menu in the BrightEye software. When DVI (digital) is used, Mitto auto senses the
resolution and you do not need to indicate the resolution on the VGA Resolution control.
EDID
In many installations Mitto will sit between your PC and monitor. The default conguration for Mitto is
that it reports its own EDID to your computer.
Most DVI and HDMI monitors support HDCP encryption which will not work with BrightEye Mitto™.
If the computer handshakes with the computer monitor and HDCP is enabled, the encryption will
cause the Mitto output to be disabled or distorted. For this reason Mitto provides its own EDID to the
computer.
Verifying Resolution Settings for PC and Mac
To make sure that your chosen resolution is being delivered to the Mitto correctly:
From the BrightEye control software’s Input menu, look at the "Input Width" and "Input Height"
indicator display of the Mitto.
Make sure that these values match what you have selected in the Display control panel. Some
video cards may scale their output at some resolutions. You may need to experiment with dierent
resolutions to nd one that works properly.

DVI/VGA to 3G/HD/SD Scan Converter User Guide
Audio/Digital Audio In
Analog Stereo: This is a two-channel input using a standard 1/8” mini-jack. It can be connected directly
to the analog audio line level output of a tower or laptop computer. If your computer does not have a
line level output, you can also use the headphone output of the computer. The level of this output can
depend upon several settings in the computer. The Windows or Mac OS X audio control panels as well
as the specic application software will both aect the output level. The general recommendation is to
set both of these controls to 80% of their maximum value.
AES or S/PDIF Digital Audio: Mitto can accept four channels of digital audio. A pair of digital audio
channels is carried in an AES or S/PDIF bit stream. Mitto can receive digital bit streams on the same
audio mini-jack connector. The channels 1/2 bit stream is received on the“left” input of the connector,
and the channels 3/4 bitstream is received on the “right” input of the connector. These inputs are
processed through sample rate converters which accommodate sampling frequencies from 44.1 to
96 KHz.
RS-232 / GPI
The RS-232/GPI port can be used with third-party control and automation systems. GPI and RS-232 are
supported simultaneously. Additionally, the Ensemble Designs Avenue GPI control panel (part number
XYCP) can be used.

CONFIGURATION AND CONTROL
Control and operation of the BrightEye Mitto™ is performed from the front panel, the BrightEye
Control application, or thru the RS-232/GPI port. Mitto’s front panel controls provide extensive
control for screen selection and most of the video and audio parameters. Some control settings and
parameter choices are available only with BrightEye PC or Mac software. These parameters cannot be
monitored from the front panel.
Adjusting Parameters from the Front Panel
The six buttons on the right side of the Mitto’s front panel are used to navigate the controls. If you are
familiar with our BrightEye products, you will notice that the Mitto has three additional buttons.
Prev and Next navigate through the various controls, such as Aspect and Position. When a control is
selected its LED blinks on and o. Arrows change values for the control you selected.
Pressing the Right Arrow or Left Arrow advances the selection within a given section of parameters,
or increases (Right Arrow) or decreases (Left Arrow) the value of a selected parameter.
Resetting to Default Values
Holding the Left Arrow and Right Arrow buttons at same time restores the selected control to its
default value. For example, with the Position control selected, pressing the Left Arrow and Right
Arrow buttons at the same time will cause the horizontal Position value to be restored to its default
value, which is all the way to the left side of the computer monitor. Similarly, with the Position control
still selected, holding the Up Arrow and Down Arrow buttons at the same time restores the vertical
Position to be restored to its default value, which is at the top of the computer monitor.
The front panel LED indicators light green when in their default values, and they light orange when
values other than the default are selected.
Press and Hold to Accelerate Movement Controls
The arrow buttons have a hold function. The behavior of pressing and holding an arrow button
depends on which control you have selected. For example, with the Position control selected, if you
press and hold the Right Arrow button, the screen selection will move at an increasing rate to the
right across the computer monitor.
