Using the card with other Datapath products
The VisionRGB-E2/E2S captures the HD/HDMI/analog 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, VisionRGB-E2/E2S transfers the data directly to the graphics card
thereby increasing performance. The VisionRGB-E2/E2S sends the relevant portions of each captured im-
age 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 RGB/DVI data is displayed on a non Datapath graphics card, the VisionRGB-E2/E2S sends the
data to system memory or direct to the graphics card, dependant on the software used for display.
