Chapter 1 – Introduction
Overview
AJA’s ROI family of scalers/scan converters allows exceptionally high quality
conversion of computer and video signals in a small Mini-Converter form factor.
The ROI models offer Region of Interest (ROI) support allowing DVI, HDMI, Display
Port, and SDI input signals to be scaled and converted to a SDI output. The ROISDI model also provides a scaled HDMI output. With incredible image scaling,
extensive aspect ratio and frame rate conversion, ROI fulfills the need to scale
computer and video to a desired resolution, all in realtime, in a very portable and
easy to use package.
The four models of ROI Mini-Converters available are:
• ROI-DVI
• ROI-DP
• ROI-HDMI
• ROI-SDI
Video Processing
In default mode, the ROI-DVI, ROI-DP, and ROI-HDMI models automatically detect
the input signal format and convert it to the SDI (and HDMI, for the ROI-SDI)
output video format. Their respective DVI, DP and HDMI outputs pass the signal
through without any processing, maintaining the incoming signal aspect ratio.
For the ROI-SDI, the incoming signal is passed to the SDI Loop Through Output,
without any processing, maintaining the incoming signal aspect ratio. The
processed signal goes to both the HDMI output and the SDI output.
If the SDI output raster is larger than the input raster, unused area is filled with
matte color.
To realize the full power of ROI, however, you will need to use the supplied USB
cable and AJA’s Mini-Config application to select the desired output format and
perform a variety of region-of-interest and output display scaling operations.
Once configured, the ROI unit can run standalone.
Audio Handling
ROI-DVI, ROI-DP, ROI-HDMI
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.
ROI-SDI
Digital audio embedded in the SDI input is carried through to both the SDI output
and the HDMI output. Analog audio can be output through the two analog RCA
Jacks (2 channels). Digital audio can be embedded through the SDI output as 24bit, 8 channel, and/or through the HDMI output as 24-bit, 2 channel or 8 channel.

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 ”Chapter 2 – Operation” on page 17).
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.
Features

Pixel rates are limited to a 165MHz maximum rate.
Pixel Clock Rate
ROI-DVI, ROI-DP, ROI-HDMI
The source video pixel clock is a combination of the video resolution and its
vertical rate. Some sources can generate pixel clock rates that exceed the
capabilities of the ROI-DVI, ROI-DP, and ROI-HDMI converters. It may not be
obvious what the resulting pixel clock will be for a particular resolution or vertical
rate.
For example, 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
circuitry.
When this error occurs, an “Exceeds max rate” red error message will be displayed
on the Mini-Config user interface, and the ROI will generate a full screen red
matte on the SDI output. A downstream DVI/DP/HDMI/SDI monitor will still
display the incoming video.
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 is within the ROI’s processing capability.
• Reconfigure the source signal to a resolution that ROI supports.
• On ROI-DP models, from the Genlock Screen, select ROI-DP from the EDID
Flow Through control so that the upstream source sees only the EDID of the
ROI (see ”EDID Flow Through” on page 34).
ROI Processing Capabilities
The ROI models utilize a powerful scaling processor, however, some specific
combinations of input and output ROI selections, de-interlacing, and 180°
rotations or flips can exceed the processing capacity of the ROI Mini-Converters.
In these cases, a “Processing Limit Exceeded” red error message is displayed on
the Mini-Config user interface, and the ROI will automatically turn off certain
features in order to process the picture. These features that have been turned
off will be reported and will be in red. For an example, see “Figure 19. Processing
Limit Exceeded” on page 29.
Possible solutions include:
• Reduce the size of the Region of Interest selections; input ROI, output ROI, or a
combination of both.
• Turn off 180 degree rotation and/or H and V flips, or frame delay.
• Use a progressive rather than interlace input signal.
Mini-Config Overview
Using AJA’s Mini-Config application, you can set up and control region-of-interest
and output display scaling operations, route audio, and configure genlock. MiniConfig is also used to update the Mini-Converter firmware.

Typical ROI Configurations
This section covers six example configurations of ROI, including ROI-DVI, ROIHDMI, and ROI-SDI.
Two typical configurations for using the ROI for scaling of desktop region-ofinterest computer-sourced video are illustrated in the following two figures.
In these configurations, the pass-through monitor is used to view the subject
desktop video and to use the Mini-Config application’s Screen Picker function to
select the desired region for output to SDI (see “Screen Picker Operation” on page
24).

In a parallel configuration as Figure 9, Figure 10 below shows a basic
configuration of the ROI-SDI being used to send a 3G-SDI digital video signal from
a 3G-SDI source to allow region of interest video input to a video switcher. As in
Figure 9, since the source video is not coming from the computer that is running
Mini-Config, the Screen Picker feature cannot be used in this configuration.
However, you can use the other methods for adjusting the region of interest
selection described in the section for the “Input Screen” on page 22 with either
the processed HDMI output signal or the processed 3G-SDI output signal feeding
a monitor.

Installation
Typically, ROI installation consists of the following steps:
1. Ensure the ROI is disconnected from power.
2. Connect your computer or video console monitor output to the ROI’s HDMI/
DVI/DP input connector. For ROI-SDI, connect your SDI source signal to the
ROI’s SDI input connector.
3. Connect the ROI’s HDMI/DVI/DP output connector to a second monitor
(optional). For ROI-SDI, this would be the SDI Loop output connector.
4. Connect a video monitor to the converter SDI output BNC. The ROI-SDI
offers both an HDMI output and an SDI output for the processed signal.
5. If using ROI-HDMI/DVI/DP, connect two-channel analog audio input to
analog audio connector (optional).
6. If using ROI-SDI, connect two analog RCA jacks (optional).
7. Apply power to the converter (AJA power supply included).
8. The converter will now run using the default factory settings. If you wish to
alter the factory settings, you’ll need to:
• Install the AJA Mini-Config software onto your computer.
• Attach the converter via USB cable (included).
• Make your changes using Mini-Config setup screens.
ROI Series Mini-Converter v1.516www.aja.com

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

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 MiniConverter 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.

Input Screen
Proxy Screen
Click on the Input tab to view and make changes to the converter’s input regionof-interest settings.
An input signal is required before the Input menu configuration controls are
available. When no input signal is present, the ROI unit grays out the Input menu
controls.
The Proxy Screen on the lower right shows the current region of interest setting
in green with the selection pixel size at the bottom and the input pixel size at the
top. Various controls are also available on the left.
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-ofinterest selection in three ways with no constraints:
• Use the X,Y coordinates 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.
ROI Series Mini-Converter v1.522www.aja.com

• If configuring a multiple monitor matrix, you can use the Monitor Matrix
screen to select the ROI and, when applied, will fill the X, Y, W, and H fields
with the correct values. See “Monitor Matrix Screen” on page 31.
• Drag the edges of the image representation (green proxy screen) at the
right of the selection pane. See “Click and Drag Options” on page 24.
• Use the Screen Picker button (not applicable to ROI-SDI model) to produce
a full-sized image with highlighted crop boundary box in the pass through
monitor. See “Screen Picker Operation” on page 24.
NOTE: For Screen Picker operation, the resolution of the pass-through monitor MiniConfig 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 (SD aspect ratio)
• 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 (not applicable to ROI-SDI model)
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 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.
Auto Bypass Mode
The ROI Mini-Converters remember the format of the input signal when the unit
is configured.
When Auto Bypass Mode is On (default value), if the format of the input signal
changes after configuration, the ROI unit will automatically bypass all video
processing (Region of Interest selection, rotation, flip, etc.). When the video input
signal returns to the original format, the unit will automatically turn back on all
video processing according to how it had been configured.
ROI Series Mini-Converter v1.523www.aja.com

When Auto Bypass Mode is Off, if the format of the input signal changes after
configuration, the ROI unit will apply (not bypass) automatic processing (Region
of Interest selection, rotation, flip, etc.) to the new input signal format. A change
in input signal raster size may force a change in the region of interest settings. In
this mode the ROI will automatically adjust the region of interest as necessary.
Auto Bypass Mode settings function regardless of whether the ROI is connected
to Mini-Config or is running stand-alone.
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-bypixel 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 13). 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.
NOTE: The Screen Picker feature is not supported with ROI-SDI.
ROI Series Mini-Converter v1.524www.aja.com

Figure 15. Screen Picker Cropping Overlay
ROI Series Mini-Converter v1.525www.aja.com

Output Screen
Click on the Output Tab to adjust the following parameters.
NOTE: Portions of this screen are grayed out if no input signal is present.
NOTE: Some sources can generate pixel clock rates that exceed the capabilities of
the ROI. 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/SDI monitor will still display the incoming video.
See “Pixel Clock Rate” and “ROI Processing Capabilities” on page 8 for
potential solutions.
ROI Out Scaling
Use the ROI Out Scaling pulldown menu to select one of the following:
NOTE: Mini-Config provides a Tool-tip description for each ROI Out Scaling mode.
Hover your cursor over the mode name in the drop-down menu for a
description of its function.
Auto - Automatically scales region-of-interest to maximum size with fixed aspect
ratio defined by input format (default setting).
NOTE: Auto selections in the Output screen and the Input screen are linked. Selecting
Auto from one screen will also select Auto in the other screen.
Fixed Aspect - Matte - Scales region-of-interest to maximum size to fit output
region while maintaining aspect ratio. Matting may occur if input aspect ratio
does not match output aspect ratio.
Full Screen - Scales region-of-interest to maximum size to fit output geometry.
This may change aspect ratio of the image. No matting will occur.
None – Crop/Matte - No scaling occurs to region-of-interest. It is always centered
on the output, and the area displayed is selected using the placement controls
in the Input menu.
Variable - Allows user to arbitrarily change position and scaling of region-ofinterest as it is placed into the output region.
ROI Series Mini-Converter v1.526www.aja.com

SDI Output Format
The pulldown menu offers a full range of SDI Video Formats for output. For
the complete list, see “Output Formats” on page 40. The format selection is
reported in the Mini-Config graphic depicting the SDI Output.
Matte Background
Click the Matte button to pull up the matte color panel that offers various modes
of background color selection.
Figure 16. Matte Color Selection Panel
Center Button
After a screen region-of-interest has been defined, click the Center button to
quickly center the image.
Edge Filtering Button
You can disable edge filtering with this control. This is useful if you are using
four ROIs to drive a 4K monitor matrix. Disabling edge filtering can eliminate the
vertical and horizontal lines that would occur in that situation. Default setting is
On.
Flicker Filtering Button
You can enable flicker filtering with this control. This can be useful where vertical
detail (horizontal lines) may strobe with the refresh rate of the display. Flicker
filtering can help with interlaced outputs, and when a detailed image is scaled
down into a smaller area. Default setting is Off.
NOTE: The following Rotation, Frame Delay, and Flip controls interact with each other.
If the ROI’s video processing circuit is unable to perform the processing, the
actual Off state of each control is reported in red. See “About the Rotation, Flip,
and Frame Delay Controls” on page 28 for more information.
ROI Series Mini-Converter v1.527www.aja.com

Rotation
Opens a drop down menu for selecting of a clockwise rotation setting (see Figure
18):
• 0° (no rotation, default setting)
• 90°
• 180°
• 270°
Frame Delay
Turns Frame Delay On or Off. One frame of delay is automatically applied
whenever Rotate or Flip is active. The current frame delay state (On or Off) is
reported.
NOTE: Turning Frame Delay On can be useful if you are using two ROIs
simultaneously, flipping or rotating only one of their outputs. Because a frame
delay is always applied to the flipped or rotated output, turning on the other
ROI’s Frame Delay restores their relative timing.
Horizontal Flip
Flips the output horizontally (left to right, and right to left, see Figure 17).
Vertical Flip
Flips the output vertically (top to bottom and bottom to top, see Figure 17).

About the Rotation, Flip, and Frame Delay Controls
Rotation and Flip image processing requires one frame of video delay. Whenever
a rotation or flip occurs a frame delay is automatically applied, and the Frame
Delay On status is reported, even if the checkbox isn’t selected (see Figure 18).
ROI Series Mini-Converter v1.528www.aja.com

Figure 18. Frame Delay Automatically On with Rotation
The Rotation, Flip, and Delay controls all report their current statuses. Some
specific combinations of input and output selections and 180° rotations or flips
involving 1920x 1080i input video can exceed the processing capacity of the ROI
Mini-Converter. In these unusual cases, a Processing Limit Exceeded red error
message is displayed on the UI, and the actual current settings for Rotation,
Frame Delay, and Flip are reported in red (see Figure 19).

Monitor Matrix Screen
The Monitor Matrix screen offers a calculator that lets you easily define Input
Region of Interest dimensions suitable for a multiple monitor matrix display.
Typically a monitor matrix is a horizontal and vertical stacking of monitors, with
a physical bezel distance separating the edges of the displays from each other.
Dedicating one ROI to feed each monitor, and sending the same input video to all
the ROIs, makes it possible to display that video so it spans across all the monitors.
Monitor Matrix Representation
A representation of the monitor matrix is shown in the Proxy Screen on the lower
right. Clicking selects the area of the monitor at that location in the matrix. When
row and column values are entered, a graphical representation of a matrix will
be displayed. A default monitor position will be shown as yellow. A new monitor
position can be selected by moving the mouse cursor over the desired position
and selecting it. The Input Region of Interest position (X,Y) and size (W,H) values
will then be automatically calculated. When Apply is clicked, the monitor position
rectangle will turn green. When a non-zero Bezel Width is entered, the bezel
border around that area is colored red.
Rows
Select the number of rows in the monitor matrix. Select from 1 to 20.
Columns
Select the number of columns in the monitor matrix. Select from 1 to 20.
Bezel Width
Select the bezel width of the display. This width will be used in calculating the
Input Region of Interest.
Note that adjoining displays could have a different bezel width and require a
different value entered on the ROI driving that monitor.
ROI Series Mini-Converter v1.531www.aja.com

X, Y, W, H
The currently calculated Input Region of Interest position (X,Y) and size (W,H) are
displayed here. These values are grayed out and cannot be adjusted. Once the
values are applied, they can be adjusted on the Input tab.
Apply
Click on the Apply button to transfer the current Input Region of Interest
dimensions to the Input screen.
Genlock Screen
The Genlock screens vary depending on the ROI model.
ROI-HDMI and ROI-DVI Genlock Screen
Genlock
The Genlock control offers the following options:
• Auto – use Ref Input if present, then Input signal if valid, then free-run
• Free-run – Lock to internal clock
• Ref In – Lock to the Video Reference input
• HDMI – Lock to the HDMI/DVI Input (if valid video rate)
NOTE: When HDMI is selected, ROI can lock to input formats that have a SMPTE raster
and frame rate and are within 50 ppm of the SDI output format.
NOTE: The actual resultant Genlock status is reported to the right of the selection
menu.
ROI Series Mini-Converter v1.532www.aja.com

H-Delay and V-Delay

ROI-DP Genlock Screen
EDID Flow Through
The EDID Flow Through setting selects what EDID (Extended Display
Identification Data) is provided to the upstream source (i.e., a connected
computer). EDID is used by the source to determine what resolution and format
to output on the monitor connector. You can select the EDID originating from the
ROI itself, or the EDID from a downstream device connected to the ROI output
monitor connector.
• ROI-DP – The upstream source sees only the EDID of the ROI.
• ROI/Monitor – The upstream source sees the downstream device’s EDID
if a device is connected to the output monitor connector (HDMI, DP, DVI),
otherwise the source sees the EDID of the ROI.
This control is useful if, for example, a 4K monitor is connected to the ROI monitor
output connector, in which case the pixel clock rate might be higher than the ROI
can process, resulting in a red matte on the SDI output. Choosing the “ROI-DP”
EDID Flow Through setting can solve that problem. This setting replaces the
downstream device’s EDID with the ROI EDID. The source should then renegotiate
a display format that is within the operating range of the ROI.
Genlock
The Genlock control offers the following options:
• Free-run – Lock to internal clock
• Ref In – Lock to the Video Reference input
NOTE: The actual resultant Genlock status is reported to the right of the selection
menu.
H-Delay and V-Delay
These controls let you adjust H and V delay from the sync input, by dragging the
slider or entering values in the windows on the right. Horizontal delay is entered
in pixels, while Vertical delay is entered in lines.
ROI Series Mini-Converter v1.534www.aja.com

NOTE: H and V delay adjustments are only available when the SDI Out Format is
compatible with the current sync input reference.
Audio Screen
The Audio screens vary depending on the ROI model.
ROI-HDMI and ROI-DVI Audio Screen
In default mode, the ROI passes up to eight channels of embedded audio from
the HDMI or DVI input to the SDI output, and mutes embedded audio to the
HDMI or DVI output.
NOTE: 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.
Input Select
Use this control to select which input audio to pass to the SDI output.
• HDMI - This selection passes the HDMI incoming audio to the SDI output (up
to 8 channels).
