Some working environments require constant access to RGB/VGA data from another source. Traditionally this data is transmitted over special cabling as an analog RGB signal for display on dedicated screens which sit alongside other Windows® based screens. The drawback of such a solution is that you need an extra monitor for every RGB data feed and therefore reduced space in the work environment. The VisionRGB-PRO is the ideal solution to this problem - and means you can integrate the RGB data and get rid of the dedicated terminal.

A standalone PCI plug in card, the VisionRGB-PRO captures the display output (e.g. the analogue RGB data) from 1 computer screen and then displays it as an independent application, on your Windows® desktop. The VisionRGB-PRO2 has 2 VGA compatible inputs for simultaneously feeding 2 independent data sources directly into your main PC. The data is then converted on the VisionRGB-PRO and displayed as a standard Windows® application on your desktop. All your data in one place, and no need for that dedicated monitor.

The VisionRGB-PRO can be operated with any standard graphics adapter and is supplied with Windows® XP-Pro/Windows® 2000 drivers. For applications requiring improved update rates and lower system overhead then we recommend using the Vantage4 or iH4 range of graphics adapters. The Vision RGB software, when used with the Datapath graphics cards, implements direct DMA to the graphics texture memory. The captured RGB is then rendered to the display using hardware texture mapping to greatly improve performance. This implementation dramatically improves update rates when the image is up-scaled as would be required with video wall and data wall applications

Each part of the up-scaled image is rendered by the associated graphics processor, effectively parallel processing the up-scaling process.

The VisionRGB-PRO is also supplied with a powerful software application for configuring the timing and the format of the input sources and displaying the captured data. We also provide an SDK so you can interface the VisionRGB-PRO to your own applications.

Application Guide

Desktop Applications

Display Captured RGB Video in a scaleable window


Multi-Screen Desktop Application

Use the Vantage4 or iH4 range for high performance multi-screen and multi-channel RGB capture

Video Wall and Data Wall Applications

VisionRGB-PRO, in conjunction with the Vantage4 or iH4graphics adapters providing high performance upscaling and multiple RGB capture channels.


RGB Streaming

For streaming applications the VisionRGB-PRO can be used with Windows Media Encoder® to compress and stream captured video. To replay the video use Windows Media Player®.



The Vision RGB software application now supports the recording of captured frames to disk for subsequent playback using Datapath VisionPlayer. Both VisionRecorder and VisionPlayer applications are included in the latest release of the VisionRGB-PRO driver and application software.

  • Record and playback RGB data at high frame rates.
  • Adjustable compression control for increased storage capacity.
  • Noise reduction control for improved image quality.
  • Recording rate selection in frames per second/minute/hour.

  • DMA transfers the data across the PCI bus without using host CPU cycles.
  • When used with Datapath Vantage4 or iH4 adapters, the CPU load is negligable even if the image is being upscaled to a video wall, resulting in real time performance.
  • Hardware up and downscaling for resizing the captured video.
  • The VisionRGB-PRO uses specialised dual ported video memory to ensure the highest possible performance with low system overhead.
  • The Vision RGB has 6MBytes of video capture memory per channel and can capture data at 640 x 480, 800 x 600, 1024 x 768 and 1600 x 1200 resolutions. PAL and NTSC are also supported as well as many non standard modes.
  • The VisionRGB-PRO captures data at a maximum pixel rate of 280MHz. Once captured, the data is converted to either 555, 565 or 888 pixel display formats and then transferred over the PCI bus to host memory, for display on the desktop.
  • Dynamic Input Source Selection.
  • Administrator Mode.
  • Update Indicator.
  • The VisionRGB-PRO application program is also built into the Datapath Wall Control software for video wall systems.
  • The VisionRGB-PRO is optimised for operation with the range of Vantage4 and iH4 graphics cards for maximum update rates.


The VisionRGB-PRO is available in two models:

  • VisionRGB-PRO1 - A single channel PCI capture card
  • VisionRGB-PRO2 - A dual channel PCI capture card
