OG-ROI Series openGear card v1.6 4 www.aja.com
Chapter 1 – Introduction
Overview
AJA’s OG-ROI family of scalers/scan converters provide exceptionally high quality
conversion of computer and video signals in an openGear form factor. The OG-
ROI models offer Region of Interest (ROI) support allowing DVI and HDMI input
signals to be scaled and converted to a SDI output. With incredible image scaling,
extensive aspect ratio and frame rate conversion, OG-ROI fulfills the need to scale
computer and video to a desired resolution, all in realtime.
The two models of OG-ROI openGear cards available are:
• OG-ROI-DVI
• OG-ROI-HDMI
Designed for use in high-density openGear 2RU frames, including AJA’s OG-X-
FR 2RU frame, the OG-ROI Series is capable of communicating with Ross Video’s
DashBoard Control System. DashBoard runs on Windows®, macOS®, and Linux®,
providing convenient, industry-standard configuration, monitoring and control of
the openGear architecture over a PC or local network.
Video Processing
In default mode, the OG-ROI-DVI and OG-ROI-HDMI models automatically detect
the input signal format and convert it to the SDI output video format. Their
respective DVI and HDMI outputs pass the signal through without any processing,
maintaining the incoming signal aspect ratio.
In Auto mode, if there is a difference in aspect ratio relative to the input and
output format, the unused area is filled with a user-configurable matte color. For
example, a 720p input will matte with a 625i output and vice versa. However, a
720p input will not matte with a 1080p output.
Audio Handling
Analog audio from the host can be input via 3-pin analog audio connectors
and mapped to the embedded SDI output stream. Alternatively, when an HDMI
input signal is present, the HDMI input's embedded audio can be mapped to the
embedded SDI output stream.
OG-ROI Series openGear card v1.6 5 www.aja.com
The OG-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 OG-ROI-DVI is receiving DVI input, only analog audio can
be embedded to the output.
HDCP Protection
The OG-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 OG-ROI’s DVI pass-
through connector, or on the OG-ROI’s SDI output.
Features
OG-ROI-DVI
• Converts DVI input to 3G, HD, or SD-SDI output
OG-ROI-HDMI
• Converts HDMI input to 3G, HD, or SD-SDI output
Both OG-ROI Models
• openGear compatible card (requires 2 slots, rear card included)
• Use with openGear 2RU frames
• Controlled by DashBoard network control software
• High quality scaling and scan conversion
• User-adjustable “region of interest,” separate controls for input and output
• 4:3/16:9 conversion modes supported
• Frame-rate conversion
• Automatic configuration to input video raster and frame rate
• SDI output configurable to most common SD, HD and 3G formats (1080p 60
max)
• Edge filtering control
• Rotation, Horizontal and Vertical flip controls
• Monitor Matrix setup controls
• Frame delay control
• Rear card external reference input select
• OG frame reference input 1 select
• OG frame reference input 2 select
• Rear card reference input 75 ohm termination select
• Adjustable Horizontal and Vertical video delay from sync input
• Audio input via 3-pin analog audio connectors or 8-channel embedded (if
present)
• Embedded SDI audio out (up to 8 channels)
• 5-year warranty
Pixel rates are limited to a 165MHz maximum rate.
OG-ROI Series openGear card v1.6 6 www.aja.com
Pixel Clock Rate
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 OG-ROI-DVI and OG-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 OG-ROI output
monitor connector, the source and sink could potentially negotiate a display
format (using EDID) that is beyond the capability of OG-ROI’s video processing
circuitry.
When this error occurs, an “Exceeds max rate” yellow alarm message will be
displayed on the DashBoard user interface, and the OG-ROI will generate a full
screen red matte on the SDI output. A downstream DVI/HDMI/SDI monitor will
still display the incoming video.
Possible solutions include:
• Disconnect the downstream device (for example, a computer monitor) from
the OG-ROI. Once disconnected, OG-ROI will negotiate directly with the
source to generate a video resolution that is within the OG-ROI’s processing
capability.
• Reconfigure the source signal to a resolution that OG-ROI supports.
OG-ROI Processing Capabilities
The OG-ROI models utilize a powerful scaling processor, however, some specific
combinations of input and output OG-ROI selections, de-interlacing, and 180°
rotations or flips can exceed the processing capacity of the OG-ROI cards.
In these cases, a “Processing Limit Exceeded” red error message is displayed on
the DashBoard user interface, and the OG-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 "Processing Limit Exceeded"
on page 25.
Possible solutions include:
• Reduce the size of the Region of Interest selections; input OG-ROI, output OG-
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.

Chapter 2 – Operation
IMPORTANT: Once you have configured the OG-ROI card using DashBoard, and as long
as the input format remains the same, the settings will persist when the frame
is disconnected from a controlling computer (in stand-alone mode). If you
anticipate that the input format may change, and if the current configuration
settings wouldn't make sense for a different input format, you can enable Auto
Bypass Mode (Auto Bypass Mode checkbox is selected from the Input tab). When
enabled, Auto Bypass Mode forces the OG-ROI card to use Auto in all applicable
settings when the input format changes. When the original input format is
re-connected, the OG-ROI will exit Auto Bypass Mode and restore all previously
configured settings for that format.

The DashBoard Control System requires the following components:
• openGear frame with a Frame Controller card
• Ethernet connection betweeen the controlling computer and the openGear
frame
NOTE: The openGear frame ships from AJA with the MFC-8322-S Frame Controller card
for controlling the new AJA DashBoard cards. The openGear frame also supports
the MFC-0G3-N Advanced Networking Frame Controller card, which can be used
to control compatible OG cards.
IMPORTANT: DashBoard version 8.5.1 or later is required to support the OG-ROI-HDMI
and OG-ROI-DVI cards.
DashBoard automatically discovers openGear and DashBoard Connect devices,
such as openGear frames and cards that are present and accessible on your
network.
Control Interface Basic Components
The basic components of the DashBoard Control System user interface consist of
the basic tree view of frames and cards, the card information and status panel,
and the parameter controls panel. These elements are shown below in Figure 14.
Main Sections of the DashBoard User Interface.
The basic tree view of frames and cards shows the frames and cards that are
discoverable by DashBoard on your network.
The card information and status panel, shown in the middle panel, display the
basic status of the card currently selected in DashBoard.

The parameter controls panel shows the tabs and parameters that the selected
card has available for configuration and control.

Input Screen
Proxy Screen
Click on the Input tab to view and make changes to the converter’s input region-
of-interest settings.
An input signal is required before the Input menu configuration controls are
available. When no input signal is present, the OG-ROI unit grays out the Input
menu controls.
The Proxy Screen 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 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:
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 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.
• 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 26.
• Drag the edges of the image representation (green proxy screen) at the
right of the selection pane. See "Click and Drag Options" on page 21.
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)
NOTE: Pixel aspect ratio (PAR) is accounted for in fixed aspect mode. The storage aspect
ratio will change based on the input's PAR to achieve a display aspect ratio
equivalent to your configured settings.
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 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
Once you have configured the OG-ROI card using DashBoard, and as long as
the input format remains the same, the settings will persist when the frame is
disconnected from a controlling computer (in stand-alone mode).
