Introduction
The UDC is a broadcast quality Up/Down/Cross Mini-Converter that can convert between SD, HD, and 3G video formats. Borrowing from AJA's industry leading conversion technology used in our model FS2, the UDC provides very high quality conversions at a low price. The UDC also supports 16-channel embedded SDI audio. I/Os include SD/HD/3G SDI Input and Output, HDMI output, and 2-channel RCA-style audio output. The UDC can be controlled by local DIP switches with additional control available via USB and AJA's Mini-Config application. A Reference Input allows the video output to be timed to a local reference.
Video Formats
The UDC does not convert frame rates—it works with the input frame rate. The only exception is a 3:2 function where 23.98 is converted to 59.94 (and 24 is converted to 60). If a reference is provided, it must be in the same frame rate hierarchy as the input video (e.g., 23.98/29.97/59.94, 25/50, or 24/30/60).

UDC Converter, Simplified Block Diagram
I/O Connections
Installation
Typically, UDC installation consists of the following steps:
- Ensure the UDC is disconnected from power.
- C connect video equipment to the converter BNCs and HDMI connector.
- Connect audio equipment to RCA connectors (optional)
- Ap ply +5 to +20 VDC power to the converter (AJA power supply model DWP or DWP-U).
- T he UDC will now run using the default factory settings. If you wish to alter the factory settings, see the following User Controls section.
User Controls
The UDC can be used right out of the box for many applications, since it is designed to recognize inputs and perform standard actions automatically. However, you can also manually configure the UDC using either of two methods:
- "Mini Config" software application supplied for PCs and Macs
- DIP switches accessible via a cutout on the back of the UDC case
One of the DIP switches is a "Local/Remote" switch. When in the "Local" mode, the remaining DIP switches support a subset of the user controls. When in the "Remote" mode, the normal Mini-Converter non-volatile registers control the unit (as last set).
Using Mini Config for Configuration and Viewing of Settings
The AJA Mini Config application, which displays a graphical view of the module's input/output status, offers more complete control of the UDC than is possible using the DIP switches. Versions of the Mini Config application are available to run on both Windows and Macintosh host platforms. Mini Config automatically scans the USB bus for connections to AJA modules and configures itself for the type of product discovered. The following describes Mini Config operation when connected to a UDC module.
Installing Mini Config on a Mac
To install the application on a Mac, simply insert the CD supplied with the Mini-Converter into the computer, and drag the "AJA Mini Config" application for your platform (Mac or PC) to your desktop or an applications folder.
Note: Macintosh computers must be Intel-based (G5, G4 and earlier models will not work with Mini Config.
AJA MiniConfig
Installing Mini Config on a PC
To install the application on a Windows PC, insert the CD supplied with the MiniConverter into the computer, locate the "Minilnstaller" application, and then double-click it.
A Setup Wizard will guide you through the installation. Just click Next to begin.
Answer all questions in the subsequent dialogs; when
you're done, you will be able to locate the Mini Config application in the AJA folder in the Programs listing.
Running Mini Config
Connect a UDC Mini-Converter to the PC or Mac via the supplied USB cable. Connect power to the Mini-Converter (DWP or DWP-U recommended).
Note: On a Mac, when the Mini-Converter is connected to the USB port, you may see an alert like the one shown here. If you do, press Cancel—this alert can be ignored.
To run Mini Config on a PC, find the AJA Mini Config in the program list and locate the AJA Mini Config application.
To run Mini Config on a Mac, double-click the Applications folder and locate the AJA Mini Config application. Double-click the AJA Mini Config application to launch it.
Once AJA Mini Config is running (PC or Mac), it looks pretty much the same, regardless of the platform.
A File menu at the top of the Mini Config application menu bar allows you to Save the current state of the Mini-Converter—with all the settings you’ve made—to a file for later recall. This allows you to set up the converter for different applications, storing each (with Save) to a unique name for easy recall later—using 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 Mini Config
When the application is running, you'll see a simple graphical interface for viewing settings and updating software. This user interface consists of an information area at the top that shows the available Mini-Converters attached to the computer via USB (in this case your UDC), with a graphical rendering of the selected Mini-Converter showing all the BNCs and connectors and their current states.
Mini Config, Video Screen
Colored text beside the connectors indicates signal type and what the UDC is doing. Text in blue shows the values automatically selected, while text in black shows values that have been manually selected. Text in red shows that the UDC is not detecting a signal or cannot negotiate with the attached device (even if can't detect an output device, it 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.
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 pull-down menu in the upper right hand corner.
If you want to configure and update 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.
The name of each Mini-Converter found can be seen in the menu pull-down showing the port number and converter name at the top right hand side of the screen. This allows you to select a desired Mini-Converter when there are more than one. Selecting a Mini-Converter with this pull-down menu causes this application to connect to the selected converter. The type of Mini-Converter and serial number will be shown in the graphic and text below it.
A status field at the bottom of the screen shows whether you are connected and communicating with the Mini-Converter shown using Mini-Config.
When configuring the UDC Mini-Converter, select it from the top pull-down, 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 groups of controls for each type of task to be performed.
Mini Config, Tabbed Screens
Click on any of the tabbed buttons (Video/Audio/Update/Info) and the screen below will change to match. Each of these screens are described on the following pages.
Video Tab Screen
The Video Screen is where you can configure UDC video inputs and outputs. Pull-down menu settings are described following the screen graphic.
Mini Config, Video Screen
Output: Determines the UDC output video format. (This selection is used only when the UDC module is in Remote mode as set by DIP switch #1. In Local mode, the video output format is determined by DIP switches 2-5). These are the format choices:
SD: The output video format will be 525i59.94 (for 23.98, 29.97, or 59.94 fps video inputs) or 625i50 (for 25 or 50 fps video inputs).
720p: The output video format will be 720p59.94 (for 23.98, 29.97, or 59.94 fps video inputs), 720p60 (for 24, 30, or 60 fps video inputs), or 720p50 (for 25 or 50 fps video inputs).
1080i: The output video format will be 1080i59.94 (for 23.98, 29.97, or 59.94 fps video inputs), 1080i60 (for 24, 30, or 60 fps video inputs), or 1080i50 (for 25 or 50 fps video inputs).
1080psf: The output video format will be 1080psf23.98 (for 23.98 fps video inputs), 1080psf24 (for 24 fps video inputs), 1080psf25 (for 25 or 50 fps video inputs), 1080psf29.97 (for 29.97 or 59.94 video inputs), or 1080psf30 (for 30 or 60 fps video inputs).
1080p (low): The output video format will be 1080p23.98 (for 23.98 fps video inputs), 1080p24 (for 24 fps video inputs), 1080p25 (for 25 or 50 fps video inputs), 1080p29.97 (for 29.97 or 59.94 video inputs), or 1080p30 (for 30 or 60 fps video inputs).
1080p (high): The output video format will be 1080p50 (for 25 or 50 fps video inputs), 1080p59.94 (for 23.98, 29.97 or 59.94 video inputs), or 1080p60 (for 24, 30 or 60 fps video inputs).
Add 3:2 Pulldown: When the Add 3:2 Pull down box is checked, 23.98 fps and 24 fps video inputs are converted to 29.97 fps and 30 fps, respectively, by adding 3:2 pull down before conversion. Note that this selection is only used when the UDC module is in Remote mode (DIP switch #1). In Local mode, 3:2 pull down addition is determined by DIP switch #6.
Genlock: Determines the timing reference for the UDC video output. The selected reference is displayed to the right of the Genlock pull-down. These are the choices:
Auto (default): Auto uses the reference input if present, or locks to the SDI input if no reference is present or if the reference is present but is not compatible.
Lock to Input: Always locks to the SDI input.
Lock to Reference: Always locks to the Reference input – if the supplied reference is not compatible, reverts to Free Run.
Free Run: Always operates in Free Run mode.
Up Convert: Determines the mode when converting from SD input video to an HD output video format. This selection is only used when the UDC module is in Remote mode (DIP switch #1). In Local mode, the up convert mode is determined by DIP switch #7. These are the choices:
4x3 Pillar: Produces 4x3 image at center screen with black sidebars.
14x9 Pillar (default): Produces 14x9 image, zoomed slightly to fill a 14x9 image with black sidebars.
Full Screen: Produces anamorphic full screen display.
LB to Full Image: Produces image zoomed to fit the full screen (letterbox).
Wide Zoom: Produces an image sized to fit a 16x9 screen using a combination of zoom and stretch. (This can introduce a small aspect ratio change.)
Down Convert: Determines the mode when converting from HD input video to an SD output video format. Note that this selection is only used when the UDC module is in Remote mode (DIP switch #1). In Local mode, the upconvert mode is determined by DIP switch #8. These are the choices:
Crop (default): Image is cropped to fit new screen size.
Anamorphic: HD image is converted to full-screen SD with a 16x9 aspect ratio (anamorphic).
14x9: Image is reduced slightly with aspect ratio preserved. Black is added top and bottom, and the left and right sides are cropped.
Auto AFD: Automatically selects the best Downconvert mode based on the input video's Active Format Description (AFD) code. If the input video is not carrying an AFD VANC code, the Downconverter defaults to crop.
Letterbox: Image is reduced with black top and bottom added to image area, with the aspect ratio preserved.
Aspect Convert: Determines the mode when converting from SD input video to an SD output video format. There is no DIP switch equivalent for this control. The setting is saved in nonvolatile memory in the module and used for all subsequent operation. These are the choices:
Off (default): The input image is copied to the output with no scaling.
Letterbox: The input frame is scaled vertically to a 16x9 "letterboxed" size (anamorphic to letterbox conversion).
H Crop: The input frame is scaled horizontally to 16x9, then center-cropped (anamorphic to center crop conversion).
Pillarbox: The input frame is scaled horizontally to make a pillarbox output (4x3 to anamorphic conversion).
V Crop: The input frame is scaled vertically to make a vertically cropped output (letterbox to anamorphic conversion).
14x9: The input frame is scaled horizontally and vertically as a compromise between H Crop and Letterbox (anamorphic to 14x9 conversion).
Loss of Input: Determines what action is taken when input video is lost. These are the choices:
Black (default): The output goes to black.
Freeze: The output freezes on the last good frame.
HDMI Tab Screen
Provides user selection of the HDMI output modes. There is no DIP switch equivalent for these controls. The setting is saved in nonvolatile memory in the module and used for all subsequent operation.
Mini Config, HDMI Screen
HDMI Video Output: The HDMI video output always mirrors the SDI video output, both in content and output format selection. Note: when the output format is set to 1080psf23.98 or 1080psf24 the HDMI output is disabled since HDMI does not have a corresponding supported format.
Protocol: Selects whether the HDMI output uses DVI or HDMI protocols for sending video to the destination device. These are the choices:
Auto: UDC automatically selects the output protocol based on getting the attached HDMI device's EDID information. This is the recommended setting. The selected protocol is shown to the right of the popup control.
HDMI: UDC uses HDMI protocols regardless of the attached device's EDID.
DVI: UDC uses DVI protocols regardless of the attached device's EDID. Because DVI protocols do not support audio or HDMI InfoFrame ancillary data, select this mode only if you know that the attached device requires it.
Color Space: Selects the HDMI output color space and depth. These are the choices:
Auto: UDC automatically selects the mode based on getting the attached HDMI device's EDID information. This is the recommended setting. The selected mode is shown to the right of the pull-down control.
RGB 8Bit: UDC uses 8-bit RGB mode regardless of the attached device's EDID.
RGB 10Bit: UDC uses 10-bit RGB mode regardless of the attached device's EDID.
YCbCr 10Bit: UDC uses 10-bit YCbCr mode regardless of the attached device's EDID.
RGB Range: Selects the HDMI video levels when the Color Space is RGB 8Bit or RGB 10Bit.
Auto: The UDC automatically selects the mode based on getting the attached HDMI device's EDID information. This is the recommended setting. The selected mode is shown to the right of the popup control.
SMPTE: The UDC scales the output video level to 8-bit range 16 - 235 (10-bit 64 - 940) regardless of the attached device's EDID.
Full Range: The UDC scales the output video level to 8-bit range 0 - 255 (10-bit 0 - 1023) regardless of the attached device's EDID.
Audio Tab Screen
The Audio Screen is where you can configure UDC HDMI and analog (RCA-style) audio output channels. Pull down menu settings are described following the screen graphic. There is no DIP switch equivalent for these controls. The setting is saved in nonvolatile memory in the module and used for all subsequent operation.
Mini Config, Audio Screen
SDI Output (Embedded) Audio: The output audio is a channel-for-channel copy of the input SDI embedded audio. There are no user controls.
HDMI Audio: Selects how many SDI channels are passed to the HDMI connector and which channel pairs are selected. These are the choices:
Auto: The UDC automatically selects the audio output configuration based on communicating with the attached HDMI device. The resulting mode is displayed to the right of the popup control.
2 Channel: Outputs a pair of channels from the SDI stream to two channels on the HDMI output connector. The selected audio pair is determined by the Analog Audio setting (below).
8 Channel: Outputs SDI channels 1 through 8 to the HDMI output connector.
Analog Audio: Selects the channel pair that will be output to the Analog RCA connectors (L/R) and the HDMI audio output (when HDMI Audio is in 2-channel mode). These are the choices:
Channel 1+2, Channel 3+4, Channel 5+6, Channel 7+8, Channel 9+10, Channel 11+12, Channel 13+14, Channel 15+16
Update Tab Screen
Use this Update screen to view the software version currently installed on the UDC or to install new software.
Mini Config, Update Screen
Note: When discussing Mini-Converters, "Firmware" is software that will be stored in the Mini-Converter's non-volatile memory and used when it is powered up. This is different from the Mini Config application software. The version numbers shown in the Update screen refer only to the firmware.
The following fields and controls are present in this screen:
Installed: This field shows the version of the UDC firmware currently installed.
Desired: This field shows the version of firmware embedded in the Mini-Config application, which you can install into the Mini-Converter by clicking the Update button.
Update: This button initiates a software update operation, loading the "Desired" version of firmware into the Mini-Converter's non-volatile memory.
Progress: This indicator bar shows the progress of software being installed.
Software Update Procedure
Use the Update screen to update the UDC software as follows:
-
Check the A JA website for new Mini-Config software for your Mini-Converter. If you find new software, download it and uncompress the (zip) file archive. Use this URL to check for new software: http://www.aja.com/support/converters/converters-mini-rackmount.php
-
Connect the Mini-Converter to a Mac or PC via a USB port on the computer, and run the new Mini-Config software you just downloaded.
-
Click on the Update tab screen.
-
Check the installed version level against the Desired version level. If the Desired is newer, click the Update button to download the new firmware to the MiniConverter; progress will be shown via the "Progress" thermometer bar. When you click Update, Mini Config will provide a dialog asking you to confirm that you really want to update the firmware (see below).
Info Tab Screen
This screen provides basic information about the Mini-Converter. This information, which consists of unit identifying information, is mostly useful when calling AJA Support for service or technical support.
Mini Config, Info Screen
Name: This field allows you to give your Mini-Converter a name. This may be useful if you have several Mini-Converters attached to a single Mac/PC via USB so you can distinguish one of them easily (especially if they're the same model). In the example show previously, the UDC has been named "pilot." To change the value, type in a new name and click the "Set Name" button.
Type: This is the factory set model name of the Mini-Converter (UDC).
Assembly: This is the factory assembly number.
Serial Number: This is the factory set unique serial number of your UDC. If you ever call AJA Support for service, you may be asked for this number.
Using DIP Switches to Control the UDC
In addition to the Mini-Config application discussed earlier, you can also control the unit via an 8-switch DIP, accessible through a cut-out in the bottom of the unit.
The default positions are shown in the figure on the left. The default settings result in an output of 1080i59.94 with NTSC related inputs and 1080i50 with PAL related inputs.
For 1080p23.98/1080psf23.98 inputs, the input can be converted to 720p23.98, 1080p23.98, 1080i59.94, or 1080p59.94. The latter two would use the 3:2 DIP switch to add 3:2 pulldown.
Note: HDMI monitors may not support all frame rates or "pSF" formats.
The compliance label, found on the back of the UDC, lists the DIP switch settings. The functions of the DIP switches and what they control are also described on the following pages.
Switch 1 (CONTROL)
This switch determines whether the UDC is configured via DIP switch or Mini-Config software.
| LOCAL (LEFT) REMOTE (RIGHT) | |

Conversion Mode Discussion and Examples
Upconvert Mode
The UDC allows you to select the type of Upconversion performed on an SD source input. This mode is in effect only when the input is SD (525i or 625i) and the selected output format is HD (720p, 1080i, or 1080p).
Upconvert Mode
escriptions
Full Screen - 4x3 image is stretched horizontally to fill a 16x9 frame.
4x3 Pillar - 4x3 image at center screen with black sidebars.
LB to Full - 4x3 letterboxed image is scaled to fit horizontally in a 16x9 frame. Black bars top and bottom are cropped off.
14x9 Pillar (default) - 4x3 image is scaled to create a 14x9 image with black sidebars and slightly cropping top and bottom of original image.
Wide Zoom – A combination of scaling and stretching is used to fit to a 16x9 frame. Slight cropping of top and bottom and a small aspect ratio change

This mode determines the type of Downconversion performed on the selected HD source input. See the following Downconvert Illustrations for Downconversion examples. This mode is in effect only when the input is HD (720p, 1080i, or 1080p) and the selected output format is SD (525i or 625i).
| Downconvert Mode | Descriptions |
| Letterbox – Image is reduced with black top and bottom added to image area, with the aspect ratio preserved.Crop (default) – Image is cropped to fit new screen size.Anamorphic – HD image is converted to full-screen SD with a 16x9 aspect ratio (anamorphic).14:9 – Image is reduced slightly with aspect ratio preserved. Black is added top and bottom, and the left and right sides are cropped.Auto AFD – Automatically selects the best Downconvert mode based on the input video's Active Format Description (AFD) code. |
Note: Active Format Description (AFD) codes are carried in the vertical ancillary (VANC) portion of HD SDI video signals, specified in SMPTE 2016 as follows: "AFD information is intended to guide DTV receivers and/or intermediate professional video equipment regarding the display of video of one aspect ratio on a display of another aspect ratio."
In the UDC Downconverter, the AFD code on the video input can be used to guide the Downconverter in choosing which mode to use to best display the important content of the 16:9 HD input video on the 4:3 SD output. For example, if the input AFD code is 10 (Full Frame), it means that the input video has important picture information throughout the full 16:9 frame, so the Downconverter should use Letterbox mode to be sure none of the content is cropped off. An AFD code of 9 (Pillarbox) says that the input video only has content within the center 4:3 area of the picture (usually because it originally came from an Upconverted SD signal) so the Downconverter Crop mode would be the best choice. There are 16 possible HD AFD codes, of which 8 are in common use. The UDC does not process or use SD AFD codes.

SD Aspect Ratio Convert
This mode selects the type of SD-to-SD Aspect Ratio Conversion (ARC) performed on an incoming selected SD source. This mode is in effect only when the input and output are both SD (525i or 625i). (In Europe 16:9 anamorphic video is also known as "wide screen" video.)
