Using the card with other Radian Video Wall Processor products
The Video Capture Cards 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 Radian Video Wall Processor graphics card is used, the Video Capture Card transfers the data directly to
the graphics card, increasing performance. The Video Capture Card 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 uses 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 graphics card with the same benefit of non-tearing captures.
When the data is displayed on a non Radian Video Wall Processor graphics card, the Video Capture Card sends
the data to system memory or direct to the graphics card, depending on the software used for display.
