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 th
