DVI2USB uses the ubiquitous and inexpensive USB port to capture output from virtually any VGA or DVI or HDMI source source—such as a Windows PC, a Macintosh OSX, a Unix machine, an embedded system, a medical device, scientific or lab equipment, and more. Using Epiphan or 3rd party applications, can then broadcasts these images over public, private or broadband wireless networks, enabling remote diagnosis of medical, military, and other situations in which a precise image is required for accurate decision-making.

This digital video capture device provides a simple, lightweight and rapid means of conveying mission-critical VGA, DVI and HDMI images without degradation due to traditional methods of compression. DVI2USB also enables users to:

Control the trade-off between image quality and image refresh rate, making it a flexible solution for a variety of applications
Carry a single capture device that can capture VGA, DVI or HDMI

As a compact external device, DVI2USB is easy to use and to transport. About the size of a small paperback book, it is easily plugged in making it simple to set-up for any individual with basic knowledge of computers.

The product ships complete with all required hardware and connectivity and a power supply. Software development kits are also available for specialized applications.

VGA Capture
In order for the DVI2USB to capture a VGA video source signal, the VGA-to-DVI adapter must be connected to the DVI port of the DVI2USB (included with DVI2USB).

DVI Capture
DVI2USB is capable of capturing any single-link DVI signal (up to 1920×1200). If you require dual-link DVI capture or support for resolutions above 1920×1200, you need DVI2USB DUO.

HDMI Capture
HDMI capture is possible using a HDMI to DVI adapter (purchased separately). The audio stream will not be captured during HDMI capture. Furthermore, HDCP or copy-protected content cannot be captured using DVI2USB.

Display Port and Mini Display Port Capture
Mac users can use an adapter to capture DVI from mini display port, display port and thunderbolt interfaces.
