U-TAP Series HDMI or SDI to USB Mini-Converter v1.2 4 www.aja.com
Chapter 1 – Introduction
Overview
AJA’s U-TAP Mini-Converter series provides video professionals with inexpensive,
extremely compact devices that convert an HDMI 1.4a or 3G-SDI video stream to
USB 3.0. U-TAP accepts up to 1920x1080 HDMI or SDI inputs ranging from 23.98
fps up to 60 fps. The input signal is automatically scaled (if necessary) to the
output size determined by the host application.
The USB 3.0 interface provides enough bandwidth for full broadcast-quality video
and audio, available if the host environment can support that bandwidth. U-TAP is
powered via the USB 3.0 connection with no need for an additional power supply,
minimizing cabling and maximizing portability.
NOTE: U-TAP is compatible with standard UVC video/UAC audio drivers, which means
wide USB support by OS X and Windows operating systems, with no need
to install special drivers, and can work directly with a broad range of video
applications (for example, VLC or QuickTime player).
Two models of U-TAP are available, each with different input capabilities.
U-TAP Features
• One USB 3.0 port
• 8-bit video support
• 2-Channel embedded audio support
• Rugged compact size
• Power via USB
U-TAP-HDMI Models
• One HDMI v1.4a input
NOTE: U-TAP does not support HDCP.

U-TAP Series HDMI or SDI to USB Mini-Converter v1.2 5 www.aja.com

• One 3G-SDI BNC looping output
Video Signal Formats
The Video Signal Formats supported by U-TAP are listed in Appendix A:
Specifications (see page 11).
U-TAP Firmware
The latest U-TAP-HDMI and U-TAP-SDI firmware is installed on the units before
shipment. The firmware can be updated using a downloadable zip file for either

Chapter 2 – Installation
Unpacking U-TAP
As you unpack U-TAP, carefully examine the unit to ensure that nothing was
damaged during shipment. If you find any damage, immediately notify the
shipping service and supply them with a complete description of the damage.
AJA will repair or replace damaged units. If you find shipping damage, contact
your AJA dealer or distributor for details on how to have your U-TAP repaired or
replaced.
Save packing materials and the shipping box. If you ever require service or move
your system—use the packaging materials and box for safe shipment.
After you unpack your U-TAP, go to the AJA website to download the latest
software package and updated documentation. You will need a USB cable to
connect to your computer.
Installation Overview
The installation and setup of U-TAP is very simple. The steps of installation and
configuration are discussed here and summarized as follows:
1. Unpack the shipping box (see above).
2. Ensure that appropriate application software is installed on your USB
equipped computer, as detailed in its user documentation.
3. Connect the U-TAP USB output port to your computer, using the provided
cable. The U-TAP is powered through the USB 3.0 port.
NOTE: The first time U-TAP is connected to a computer extra time may be required for
the OS to access and configure the appropriate drivers. On Windows machines
could take from 3 to 5 minutes. On Macs this time should be much shorter.
Each OS should report successful driver installation. Subsequent U-TAP USB
connections should occur immediately.
4. Connect the SDI or HDMI input to your source device.
5. U-TAP will now be operational, automatically detecting the input signal
format and decoding the video (and two channels of embedded audio if
present) to the USB output.
NOTE: Connecting multiple U-TAPs could compromise power delivery, and excessive USB
bus traffic (from another U-TAP or other devices sharing that USB bus) can reduce
the computer’s performance.
6. Launch your video application on the connected computer and use its
UI controls to access the video and audio being converted by U-TAP. For
example:
• For VLC, go to Media/Open Capture device, and select U-TAP.
• For QuickTime Player, go to File menu, click New Movie Recording, and
select U-TAP using the down arrow next to the record button.
