Using the card with other Datapath products
The VisionRGB-X2 captures the HD/HDMI/ RGB/DVI 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, the VisionRGB-X2 transfers the data directly to the graphics
card thereby increasing performance. The VisionRGB-X2 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 VisionRGB-X2 sends the data to
system memory or direct to the graphics card, dependant on the software used for display.
