Introduction
The VisionRGB-PRO captures most RGB/VGA video sources.
The VisionRGB-PRO is an ideal solution in many applications where information is
distributed as RGB/VGA, including display/process monitoring in engineering, and for
secure data in financial institutions and trading floors.
Windows Media Encoder® can be used to stream video across a network or save the
video to disk. Windows Media Player® can be used to display the stream or the
video that has previously been saved.
Using our SDK, you can interface to your own application programs.
Hardware Overview
Each VisionRGB-PRO channel can capture up to 1664x1260 pixels from a RGB
source with a dot clock up to 280MHz. The RGB data is stored in a 6MB frame buffer
on the VisionRGB-PRO card in real time.
The RGB data is transferred using PCI bus master DMA with scatter gather.
The RGB data can be transferred to system memory or to off-screen memory on a
Datapath iH graphics card.
The RGB data can be displayed or processed in other ways.
Typical update rates with a standard VGA graphics card are:
1 channel at 1280 x 1024
1 channel at 1024 x 768
Typical update rates with a Datapath iH4 or Horizon graphics card are:
-
12Hz.
-
17Hz.
