Chapter 1: Introduction
Overview
AJA’s ROI (region of interest) scaling converters can be used out-of-the-box to convert
either HDMI, DisplayPort (DP), or DVI input signals (depending on model) to SDI output.
The three models available are ROI-HDMI, ROI-DP, and ROI-DVI. In default mode, each ROI
converter automatically detects the input signal format and converts it to the SDI output
video format. In this startup Auto mode, the full-size input is output to the SDI output.
The picture’s aspect ratio is maintained and if the SDI monitor is larger than the input
signal, unused area is filled with matte color. Default audio setup passes 8-channels of
embedded audio (if present).
To realize the full power of ROI, however, you will use the supplied USB cable and AJA’s
Mini-Config application to select SDI output format and perform a host of region-of-
interest and output display scaling operations.
Audio Handling Analog audio from the host can be input via a standard 3.5mm audio cable and mapped
to the embedded SDI output stream. Alternatively, if the input is HDMI or DP, its
embedded audio can be the audio input. The ROI-DVI model can receive both DVI and
HDMI protocol input, and accepts audio if it is embedded in an HDMI signal. However,
the DVI protocol does not carry audio, so if the ROI-DVI is receiving DVI input, only analog
audio can be embedded to the output.
Control Interface For control, the ROI is connected to a computer via USB. The ROI has no local, physical
user-interface (no dipswitch settings). The ROI can operate stand-alone without a USB
connection to the host. In this mode, the ROI automatically adapts to the input signal,
and operates according to defaults or as last configured via the AJA Mini-Config
application (see “Operation” on page 12).
HDCP Protection The ROI honors HDCP, and will not allow an HDCP link. If the input content is HDCP
protected, no source video will be displayed on the ROI’s DVI pass-through connector, or
on the ROI’s SDI output.

NOTE: Pixel rates are limited by to a 165MHz maximum rate.
Pixel Clock Rate Some sources can generate pixel clock rates that exceed the capabilities of the ROI
converter. The pixel clock is a combination of the video resolution and its vertical rate. It
may not be obvious what the resulting pixel clock will be for a particular resolution or
vertical rate.
Exceeds Max Rate
Notification
If the incoming video’s pixel clock rate is too high, the ROI converter will generate a full
screen red matte on the SDI output to indicate this error condition. Mini-Config will also
display an “exceeds max rate” error message. A downstream HDMI/DP/DVI monitor will
still display the incoming video, however.
When a downstream sink device is connected to the ROI output monitor connector, the
source and sink could potentially negotiate a display format (using EDID) that is beyond
the capability of ROI’s video processing circuity, resulting in the red matte SDI output.
Possible solutions include:
• Disconnect the downstream device (for example, a computer monitor) from the ROI.
Once disconnected, ROI will negotiate directly with the source to generate a video
resolution that it within the ROI’s processing capability. With this solution, the
downstream device will lose its signal, but the SDI output will work as expected.
• Reconfigure the source signal to a different resolution or scan rate. An alternative
setting may permit both valid SDI output and the signal displaying on a downstream
monitor.
• On ROI-DP models, use the EDID Flow Through control (see page 25).

channels for rotation and resizing. This wiring example will work provided the HDMI
cables are short. An HDMI splitter/amplifier can be used if the ROIs need to be located
farther away from the computer (Figure 7).
Figure 7. ROI Rotation with Portrait Mounted On-Set Monitors
A fourth example below illustrates sending HDMI digital video from a camera to a ROI to
allow region of interest video input to a video switcher. The Screen Picker feature cannot
be used in this configuration (Figure 8).

Chapter 2: Operation
IMPORTANT: Once the ROI has been configured with Mini-Config, those settings will continue to be
used in stand-alone mode (disconnected from USB) as long as the input format remains
the same. If a different input format is connected, the ROI will revert to Auto mode.
However, if the original input format is re-connected, the ROI will exit Auto mode and
restore the previously configured settings for that format.
USB Control and Setup—Using AJA Mini-Config
Your AJA Mini-Converter can be used right out of the box for some applications since it is
designed to recognize inputs and perform standard actions automatically by default.
However, to use its full capability, you must use AJA’s Mini-Config software application
for PCs and Macs. This same application can be used to update to new Mini-Converter
software released by AJA.
Acquiring Mini-
Config
AJA’s Mini-Config application is available for download from the AJA website.
To download the latest Mini-Config package, which includes the Mini-Config application,
Mini-Converter firmware, and documentation, go to:

Saving Setups A File drop down menu on the Mini-Config application bar allows you to save the current
state of the Mini-Converter to a preset file for later recall.
Using this feature you can set up the converter for different applications, storing each
configuration (Save Preset As...) with a unique name for easy recall (Open Preset...).
A Revert to Factory Settings menu item similarly allows you to change the settings
back to AJA’s factory defaults.
Operating Mini-
Config
The Mini-Config application provides a graphic interface for viewing settings and
updating software. It consists of an information area at the top that shows the available
Mini-Converters attached to the computer via USB, with a graphical rendering of the
selected Mini-Converter showing all the connectors and their current state.
Colored text next to the connectors indicates the signal type and what the Mini-
Converter is doing:
• Blue text indicates the values automatically selected
• Black text indicates values that you have manually selected
• Red text indicates the Mini-Converter is not detecting a signal, or cannot operate with
the current user settings.
NOTE: Even if no output device is detected, the SDI connector text still shows the signal it is
outputting.
NOTE: Configuration settings in red will change based on the attached output device as well as input
signals. For improved accuracy and reliability, you should configure the Mini-Converter only
when the target output device is attached and input signals are supplied at the inputs.
Screens are virtually the same on both PC and Mac, with subtle differences that reflect
the general look of the platform environment.
Running Multiple Mini-
Converters
Mini-Config can manage multiple AJA Mini-Converters connected via USB—even when
they are of differing types. However it only connects to one at a time. You can choose
which Mini-Converter you wish to control using the pulldown menu in the upper right
hand corner. If you want to configure multiple Mini-Converters in parallel, you can do it
by running multiple instances of the Mini-Config application and have each control a
different Mini-Converter.
NOTE: During a Mini-Converter firmware update, only one Mini-Converter should be connected
to the computer via USB.

Figure 12. Example Mini-Config Screen
Selecting a Mini-Converter with the pulldown menu causes this application to connect
to the selected converter. The graphic of Mini-Converter and text below it provides:
• Type of converter
• Firmware version
• Serial number of the unit.
A status field at the bottom of the screen shows if your application is connected and
communicating with the Mini-Converter.
The Proxy Screen shows the current region of interest setting in green with the selection
pixel size at the bottom and the DVI input pixel size at the top.
When configuring the Mini-Converter, select it from the top pulldown, view the current
settings and change any values. Making a change communicates that new value to the
Mini-Converter’s non-volatile memory.
Tabbed Screens The Tabs delineate control screens with groups of controls for each type of task to be
performed.
The controls for the actual configuration parameters are specific to each Mini-Converter
type. When you Click on any of the tab buttons, the pane below the tabs will change to
match your tab selection. Any changes you make are immediately applied and will be
saved, overwriting previous settings.
NOTE: In this manual Mini-Config screens for the ROI-DP model are shown. Other ROI models have
similar screens, with a few exceptions that are noted.

Input Screen
Click on the Input tab to view and make changes to the converter’s input region-of-
interest settings. Various controls are available, along with a green proxy screen on the
lower right that represents the currently selected region-of-interest.
NOTE: The adjustments made on the green proxy screens and Screen Picker are live and can be
viewed on the SDI output.
NOTE: Portions of this screen are grayed out if no input signal is present.
ROI Selection Using this pulldown menu you can choose a selection mode:
NOTE: Mini-Config provides a Tool-tip description for each ROI Selection mode. Hover your cursor
over the mode name in the drop-down menu for a description of its function.
• Auto - Selects the entire signal detected at the input to the ROI (default setting). Scales
the input region-of-interest as large as possible to fit into the SDI output region while
maintaining the incoming aspect ratio. Matte may result if the input’s aspect ratio does
not match the SDI out aspect ratio.
NOTE: Auto selections in the Input screen and the Output screen are linked. Selecting Auto from one
screen will also select Auto in the other screen.
• Variable - Allows user-adjustable selection of all or a portion of the input signal. When
you select Variable as the selection type, you can choose the region-of-interest
selection in three ways with no constraints:
• Use the X,Y coordinate and W,H (width, height) size fields. Within these fields, you
can enter values (if they are valid) or use your keyboard arrow keys to increment
one pixel/line at a time for fine adjustment.
• Drag the edges of the image representation (green proxy screen) at the right of the
selection pane. See “Click and Drag Options” on page 18.)

ROI Series Mini-Converter v1.2r1 www.aja.com

• Use the Screen Picker button to produce a full-sized image with highlighted crop
boundary box in the pass through monitor. See “Screen Picker Operation” on
page 19.
NOTE: For Screen Picker operation, the resolution of the pass-through monitor Mini-Config is using
must match the resolution of the input to the ROI.
• Fixed Aspect - Opens a ROI Fixed Aspect drop-down menu allowing fixed aspect input
region-of-interest selection. In this mode, the size of the selected region-of-interest can
change but the aspect ratio is held constant:
•4:3(SDaspectratio)
• 16:9 (HD aspect ratio)
• 3:4 (useful for presentation on vertically oriented monitors)
• 9:16 (useful for presentation on vertically oriented monitors)
• Fixed Size - Opens a ROI Fixed Size drop-down menu allowing fixed size input region-
of-interest selection. In this mode, the region-of-interest selection can change position
on the input screen but the size cannot be changed. These settings allow you to easily
select standard video sizes for region-of-interest.
•DV
•NTSC
•PAL
• 720HD
• 1080HD
• SDI Out - Forces the region-of-interest to have the same aspect ratio as the current SDI
Out Format setting
RGB Range Menu The RGB Range pulldown menu allows you to select either Full range (0-1023) or SMPTE
range (typically 64-940) for RGB color input.
Full Screen Button Click the Full Screen button to quickly set the region-of-interest to the full input raster
size.
Center Button If you choose anything other than a full-sized image (Auto) in the ROI Select menu, you
will have complete control of where the region of interest selection is placed. To quickly
and precisely center the region-of-interest, click the Center button.
Click and Drag
Options
When using the drag method for region-of-interest placement or resizing, you can use
the Option/ALT, Shift, and Arrow keys for precise adjustments.
Option/ALT key: For more control, hold down the Option/ALT key while dragging the image boundary.
You will notice that the selection changes in a more gradual pixel-by-pixel manner
regardless of your drag speed.
Shift key: You may change the image size while maintaining the current aspect ratio, by holding
down the Shift key as you drag.
Arrow Keys: You can use the keyboard arrows to increment size and placement of a variable region-
of-interest selection one pixel at a time in X,Y,H,W fields and in the proxy and Screen
Picker screens. (The up/down arrow keys can also be used to step through some menu
selections.)

Screen Picker
Operation
When Variable region-of-interest selection is enabled, pressing the Screen Picker button
activates Screen Picker mode. A full-sized image with highlighted crop boundary box is
displayed in the pass through monitor (refer to “Typical ROI Configurations” on page 8).
Adjust the region-of-interest boundaries by dragging the image sized to the desired
locations, and then press the Enter or Return key to exit Screen Picker mode.
NOTE: For Screen Picker operation, the source video must be coming from the same PC that is
running Mini-Config, and the resolution of the pass-through monitor Mini-Config is using
must match the resolution of the input to the ROI.
