Using the card with other Datapath products

The VisionAV-SDI captures data and stores it in an on-board video buffer.  This data is then copied using 
DMA to the host system for display, storage or streaming.

When a Datapath graphics card is used, VisionAV-SDI transfers the data directly to the graphics card 
thereby increasing performance.  The VisionAV-SDI sends the relevant portions of each captured image 
to each display channel and instructs each channel to use its graphics engine to render the data.  This fully 
utilises the hardware and dramatically increases performance.

When a Direct3D compatible graphics card is used the data can be transferred direct to the graphics card 
in a similar manner to the Datapath graphics card with the same benefit of non-tearing captures.

When the data is displayed on a non Datapath graphics card, the VisionAV-SDI sends the data to system 
memory or direct to the graphics card, dependant on the software used for display.
