DVI2USB - External DVI Frame Grabber
|
DVI2USB is the only external, dual-mode (VGA & DVI) frame grabber that can capture and broadcast diagnostic-quality images and videos from any device with a monitor and transfer to a USB port on another computer. No peripheral component interface (PCI) is required. Its high-quality output is designed specifically for medical and military applications.
DVI2USB uses the ubiquitous and inexpensive USB port to capture output from virtually any VGA or DVI source—such as a Windows PC, a Macintosh OSX, a Unix machine, an embedded system, a medical device, scientific or lab equipment, and more. It 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.
The product provides a simple, lightweight and rapid means of conveying mission-critical VGA and DVI 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
- Print or record the captured image with the touch of a button using Epiphan's VGA Printer or VGA Recorder products
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.
