Introduction

The VisionHD4 is a high end, four channel, high definition video capture card delivering performance

and flexibility in demanding environments.

The VisionHD4 has four independent video capture channels, supporting high definition capture and

analogue video. The signals are input on four DVI-I connectors provided by a pair of Datapath DVI

splitter cables. Each input can support HDMI, DVI, VGA and analogue Component (YPbPr) at all

resolutions up to 4096 x 2048, at 165 MHz Pixel Clock (digital modes) or 170 Msps in analogue modes.

The VisionHD4 captures all four video channels simultaneously and triple buffers them into onboard

storage for tear free video, alongside up to four audio streams that can be selected from the HDMI

audio ports. This data can then be processed and copied using DMA transfers to the host system for

display, storage or streaming.
