Introduction

Overview

Control Interface: For control, the ROI is connected to a computer via USB. The ROI has no local, physical
HDCP Protection The ROI honors HDCP, and will not allow an HDCP link. If the input content is HDCP
AJA’s ROI (region of interest) scaling converter can be used out-of-the-box to convert either DVI or HDMI input signals to SDI output. In default mode, ROI automatically detects the input DVI format and converts it to the SDI video format. In this startup Auto mode, the full-size DVI input is output to the SDI output. The picture’s aspect ratio is maintained and if the SDI monitor is larger than the DVI input, unused area is filled with matte color. Default audio setup passes 8-channel HDMI audio.
To realize the full power of ROI, however, you will use the supplied USB cable and AJA’s MiniConfig application (included on your CD) 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 stream. Alternatively, if the input is HDMI, the embedded audio can be the audio input.
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 DVI/HDMI signal, and operates according to defaults or as last configured via the AJA MiniConfig application (see
protected, no source video will be displayed on the ROI’s DVI pass-through connector, or on the ROI’s SDI output.

Typical ROI Configurations

Three typical configurations for using the ROI for scaling of desktop region-of-interest video are illustrated in the following figures. In these configurations, the pass-through monitor is used to view the subject desktop video and use the MiniConfig application’s Screen Picker function to select the desired region for output to SDI (see

Installation

Typically, ROI installation consists of the following steps:
1. Ensure the ROI is disconnected from power.
2. Connect your computer or video console (DVI/HDMI) monitor output to the ROI DVI
input connector.
3. Connect the ROI DVI output connector to a second computer monitor (optional).
4. Connect video monitor to the converter SDI output BNC.
5. Connect two-channel analog audio input to analog audio connector (optional)

6. Apply power to the converter (AJA power supply included).
7. 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 MiniConfig software (supplied on CD) onto your computer.
• Attach the converter via USB cable (included).
• Make your changes using MiniConfig setup screens.

Chapter 2: Operation

IMPORTANT: Once the ROI has been configured with MiniConfig, 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 MiniConfig

The ROI 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 MiniConfig software application for PCs and Macs. This same application can be used to update to new Mini-Converter software released by AJA.
Installing MiniConfig on a Mac: To install the application on a Mac, you may download the application
from AJA.com, the computer. Simply drag the “AJA MiniConfig” app. to your applications folder.
or insert the CD supplied with the Mini-Converter into
NOTE: Macintosh computers must be Intel-based (G5, G4 and earlier models will not work with
MiniConfig).
Installing MiniConfig on a PC: To install the application on a Windows PC, insert the CD supplied with the Mini-
Converter into the computer, locate the “MiniInstaller” application, and then double­click it. A Setup Wizard will guide you through the installation.
Figure 6. MiniConfig Setup Wizard
Just click Next to begin. Answer all questions in the subsequent dialogues. When you’re done, you will be able to locate the MiniConfig application in the AJA folder in the Programs listing.

Running MiniConfig Connect the Mini-Converter to the PC or Mac via the supplied USB cable. Connect the

external power supply (supplied) to the Mini-Converter.
NOTE: On a Mac, when the Mini-Converter is connected to the USB port, you may see an alert like
that shown following. If you do, press Cancel—this alert can be ignored.
PC Startup: To run MiniConfig on a PC, find the AJA MiniConfig in the program list and locate the AJA
folder and the MiniConfig application inside.
Mac Startup: To run MiniConfig on a Mac, double-click the Applications folder and locate the AJA
MiniConfig application. Double-click the application to launch it.
Saving Setups: A File menu at the top of the MiniConfig
application menu bar allows you to Save the state of the settings, to a file for later recall. This allows you to set up the converter for different applications, storing each configuration (with Save) to a unique name for easy recall with the Open menu item. A Revert to Factory Settings menu item similarly allows you to change the settings back to AJA’s factory defaults. An Edit menu allows you to cut and paste values to/from fields, just as in other applications.

Operating MiniConfig

The MiniConfig 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:
