DVI2USB 3.0 User Guide
1. Introduction
DVI2USB 3.0™ is Epiphan's external frame grabber uses a single-link DVI input
connection to transmit data to a video capture workstation through a USB 3.0 port.
The video capture workstation can capture, record and broadcast uncompressed
diagnostic-quality images and videos from a VGA and DVI sources. Both audio and
video capture is supported for HDMI sources. No peripheral component interface
(PCI) is required. This product is designed specifically for applications that require the
support of a DVI/VGA/HDMI input.
DVI2USB 3.0 captures video from any single link DVI, unencrypted HDMI, or VGA
video source. Meeting greater demands for transferring larger files at faster speeds,
this external frame grabber supports USB 3.0 technology, capable of transferring
uncompressed data with speeds of up to 5.0 (Gbits/s) - about ten times faster than
USB 2.0.
Note: In practice transfer speeds are dependent on factors such as the task and
hardware configuration.
DVI2USB 3.0 is versatile and can be used with multiple workstation configurations. It
is backward compatible with USB 2.0 connections, however it transfers compressed
video with a lower quality when using USB 2.0.
DVI2USB 3.0 supports full HD capture rate of 30 frames per second for 1080p video
and video sources with resolutions up to 1920x1200. When DVI2USB 3.0 is
configured to capture and transfer video to a third-party software, such as Windows
Media Encoder using YUV 4:2:0 color format, video can be captured and recorded up
to 60 frames per second.
For more information about increasing the frame rate when capturing, recording and
streaming video using third-party applications, refer to the How to Record Video using
Window Media Encoder tutorial on Epiphan’s website.
Physical Attributes

DVI2USB 3.0 User Guide
The DVI2USB 3.0 frame grabber is fully compatible with DirectShow in Windows,
Video4Linux in Linux, and QuickTime in Mac OS.
In addition to capturing video from DVI, VGA, HDMI (video and audio) sources,
DVI2USB 3.0 supports DisplayPort, Mini DisplayPort, and Thunderbolt sources using
a converter cable, sold separately. Resolutions of up to 1920x1200 are supported,
with a minimum capture rate of 30 frames per second.

2.2 USB 2.0 Backwards Compatibility
DVI2USB 3.0 is USB 2.0 backwards-compatible; you can connect it to the USB 2.0
port in situations when a laptop or workstation has a USB 2.0 port only. It will not
prevent you from using the frame grabber in these circumstances. DVI2USB 3.0 uses
green and blue LEDs to indicate whether it is connected to a USB 2.0 or 3.0 port.
Refer to section System Hardware Features for information on LED indicators.
Configuration Tips:
The DVI2USB 3.0 cannot transfer uncompressed video when connected to
the workstation’s USB 2.0 port. This standard provides lower transfer speed
than the USB 3.0 standard therefore the frame grabber will compress the
captured data before transferring.
Physical Attributes

DVI2USB 3.0 User Guide
The DVI2USB 3.0 must be connected to the USB 3.0 port on the video
capture workstation when capturing video and audio from an HDMI source,
otherwise only video is captured. For information about configuring a video
capture workstation to capture video and audio from an HDMI source, refer to
section Windows Capture Application.
2.3 Cables, Connectors and Adapters
High speed data transfer (up to 1.5 GB/s) is supported by USB 3.0 when you connect
your DVI2USB 3.0 to the USB 3.0 port on the video capture workstation.

Whenever possible, when splitting the VGA signal, use an active VGA splitter rather
than a passive VGA splitter (also called a Yadapter). This will help maintain a cleaner
video signal.
If the capture application cannot find the frame grabber:
Confirm that the frame grabber is connected to a video capture workstation
USB port and has power connected and the device LEDs are lit.
Disconnect and re-connect the frame grabber. This prompts Windows to

7 Linux Video Capture Workstation Software
Epiphan provides the Epiphan USB device driver and the Epiphan capture API for
Linux. Epiphan does not provide a video capture application for Linux. However, the
USB device driver is compatible with Video4Linux so you can use Video4Linux
compatible applications to receive and process captured images. You can also use
the Epiphan Linux SDK to write your own custom video capture application that
receives captured images from the Epiphan capture API. The following software
components operate on a video capture workstation running Linux:
The Epiphan USB device driver
Video4Linux
The Epiphan capture API
V4L custom video capture applications
7.1 The Epiphan USB Device Driver
The Linux Epiphan USB device driver receives images from an Epiphan DVI2USB 3.0
and delivers the images to the Epiphan capture API and to Video4Linux. Before
delivering the images the Epiphan USB device driver also performs image adjustment
to improve the quality of the image. Image adjustments include setting the sampling
phase, PLL adjustments, and Horizontal shift. The USB device driver can also change
the color depth of the captured image before sending the image to the video API. For
example, if the DVI2USB 3.0 is capturing the frames at a color depth that is different
than that required by the video capture application, the USB device driver converts the
images to the required color depth.
