Mitto Family of Scan Converters User Guide
Functional Description
Video
The BrightEye Mitto family of scan converters all accept a DVI, VGA or HDMI input. The HDMI input
requires an adaptor. The output options vary by model as follows:
BEM-1: 3G, HD, SD, Composite
BEM-1F: Fiber Optic, 3G, HD, SD, Composite
BEM-2: HD, SD, Composite
BEM-2F: Fiber Optic, HD, SD, Composite
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 x 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 output SD SDI, 1.5 Gb/s HD SDI, or 3 Gb/s HD SDI video. The output includes only 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. On Models BEM-1 and BEM-2, SDI Out 1 and 2 are both electrical outputs (BNC). On Models
BEM-1F and BEM-2F, SDI Out 1 is electrical (BNC) and SDI Out 2 is Fiber Optic.
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 in the Output Menu of the BrightEye Mac/PC software.
Audio
Mitto has four audio sources to draw from:
Analog audio in
AES audio in
Audio coming in along with an HDMI input
Mitto’s 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 a 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.
When Mitto’s internal test pattern generator is turned on (located in the Output Menu), color bars and
a 1.0 KHz tone will be on the SDI outputs.
