Using the card with other EMS products
The XtremeAV-HD1+ 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 EMS graphics card is used, XtremeAV-HD1+ transfers the data directly to the graphics card
thereby increasing performance. The XtremeAV-HD1+ 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 EMS graphics card with the same benefit of non-tearing captures.
When the data is displayed on a non EMS graphics card, the XtremeAV-HD1+ sends the data to system
memory or direct to the graphics card, dependant on the software used for display.
