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.
