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

buer. 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 benet 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.
