The HDGrabber-DVI is a high performance, High Definition, video capture and overlay card for PCI-104 systems. The HDGrabber-DVI provides a powerful and flexible solution for capturing HDMI/DVI digital video for software analysis and processing or local system display.

The HDGrabber-DVI features an advanced video scalar that reduces the frame rate of the incoming video allowing high frame-rate high resolution sources to be captured without any compression. This powerful solution supports raw video capture at Full HD resolution at 10fps (1920x1080@10Hz) from a 1080p60/1080p30 source. The flexible capture engine also supports lower resolution capture at higher frame rates. The capture engine is configurable under software control.

The HDGrabber-DVI is supported by drivers and example applications for Windows and Linux that use the OS standard DirectShow and V4L interfaces.
