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 oer 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 fullls 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 lled with
matte color.

To realize the full power of ROI, however, you will need to use the supplied USB
cable and AJA’s Mini-Cong application to select the desired output format and
perform a variety of region-of-interest and output display scaling operations.
Once congured, 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 congured via
the AJA Mini-Cong 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.

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-Cong 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.

• Recongure 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 specic
combinations of input and output ROI selections, de-interlacing, and 180°
rotations or ips 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-Cong user interface, and the ROI will automatically turn o certain
features in order to process the picture. These features that have been turned
o 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 o 180 degree rotation and/or H and V ips, or frame delay.

• Use a progressive rather than interlace input signal.

Mini-Config Overview

Using AJA’s Mini-Cong application, you can set up and control region-of-interest
and output display scaling operations, route audio, and congure genlock. Mini­Cong is also used to update the Mini-Converter rmware.

Typical ROI Configurations

This section covers six example congurations of ROI, including ROI-DVI, ROI­HDMI, and ROI-SDI.

Two typical congurations for using the ROI for scaling of desktop region-of­interest computer-sourced video are illustrated in the following two gures.
In these congurations, the pass-through monitor is used to view the subject
desktop video and to use the Mini-Cong application’s Screen Picker function to
select the desired region for output to SDI (see “Screen Picker Operation” on page

24).

A third example (Figure 8) illustrates use of the ROI Rotation feature to send
selected areas of a SDI signal to portrait mounted on-set monitors at full
resolution. Each monitor uses one ROI converter, accomplishing the task at a
much lower cost than dedicating DVE channels for rotation and resizing.

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. Since the source
video is not coming from the computer that is running Mini-Cong, the Screen

In a parallel conguration as Figure 9, Figure 10 below shows a basic
conguration 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-Cong, the Screen Picker feature cannot be used in this conguration.
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.

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
oers 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-Cong software onto your computer.

• Attach the converter via USB cable (included).

• Make your changes using Mini-Cong setup screens.

ROI Series Mini-Converter v1.5 16 www.aja.com

Chapter 2 – Operation

IMPORTANT: Once the ROI has been congured with Mini-Cong, 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 dierent 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 congured settings for that format.

USB Control and Setup—Using AJA Mini-Config
