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™ 

offers the best way to take computer video to air.  Mitto provides a way to use YouTube™ material in 

a news broadcast, show financial 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 filtering. The region you select for output determines if Mitto acts 

as an upconverter or downconverter. The filters 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 interfield flicker. Mitto’s advanced filtering satisfies 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 specific 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 offer a very handy user-

interface.
