Dual channel video capture card DVI/HD/RGB

  • High performance DMA to system memory or direct to graphics memory with scatter gather
  • On board processor for real time mode and sink detection
  • Dynamic input source selection
  • Administrator mode
  • HD capture for each channel up to 1080P at 60 frames per second, HDMI capture up to 1080p and DVI up to 1920×1200


Dual channel video capture card

This video capture has two complete capture channels supporting up to 1920×1200 DVI or 2048×1536 Analog resolution.

The XtremeRGB-Ex2+captures the Analog/DVI data and triple buffers it into onboard storage. This data is then copied using DMA to the host system for display, storage or streaming.

When a EMS graphics card is used, the XtremeRGB-Ex2+ capture card transfers the data directly to the graphics card thereby increasing performance. The XtremeRGB-Ex2+ capture card sends the relevant portions of each channel to use its graphics engine to render the data. This fully utilises the hardware and dramatically increases performance.

When the RGB/DVI data is displayed on a non EMS graphics card, the XtremeRGB-Ex2+ sends the data to system memory or direct to the graphics card, dependent on the software used for display.

The XtremeRGB-Ex2+ capture card is an ideal solution for applications require the capture of Analog or DVI sources in real time. Typical applications include:

  • Viewing Analog or DVI sources from PCs, MACs, Industrial/medical equipment, cameras and other video equipment
  • Streaming video applications
  • Video wall controllers

For streaming applications, theXtremeRGB-Ex2+ can be used with Windows® Media Encoder to compress and stream captures video. To replay the video, use Windows® Media Player.

Any application compatible with Windows® Direct-Show technology can use the XtremeRGB-Ex2+ video capture card due to its built in WDM support.
