XtremeRGB-Ex4+ video capture card with five complete video capture channels supporting a single channel for up to 1920×1080 DVI or 2048×1536 Analog resolution, plus four SD Analog capture channels, and provides a maximum data rate of 650 MB/s.


XtremeRGB-Ex4+- Four channel SD capture card

This video capture card has five complete video capture channels supporting a single channel for up to 1920×1080 DVI or 2048×1536 Analog resolution, plus four SD Analog capture channels.

The XtremeRGB-Ex4+ 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-Ex4+ transfers the data directly to the graphics card thereby increasing performance. The XtremeRGB-Ex4+ 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 utilises the hardware and dramatically increases performance.

When the RGB/DVI data is displayed on a non EMS graphics card, the XtremeRGB-Ex4+ sends the data to system memory or direct to the graphics card, dependent on the software used for display.

The XtremeRGB-Ex4+ is an ideal solution for applications that require the capture of an RGB/DVI source simultaneously with up to four SD video sources. 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

RGB Streaming

For streaming applications, the XtremeRGB-Ex4+ can be used with Windows Media Encoder to compress and stream captured video. To replay the video, use Windows® Media Player. Any application compatible with Windows® DirectShow technology can use the XtremeRGB-Ex4+ due to its built-in WDM support.

Video Streaming Support

DirectX WDM streaming driver supports the following applications, to encode, record and stream video over networks or the Internet:

  • Dataton WatchOut
  • Microsoft Expression Encoder
  • Microsoft Windows® Media Encoder
  • VideoLAN VLC
  • NorPix StreamPix
  • VitualDub
  • Adobe Flash Encoder
  • VidBlaster
  • AMCap and other DirectShow compatible software

For further details see the EMS DirectShow SDK documentation supplied as part of a typical installation.


The XtremeRGB-Ex4+ video capture card is supplied with a powerful software application for configuring the timing and format of the input sources and displaying the data. Simply connect your external DVI, Analog or video source into the card, run the XtremeRGB-Ex4+ application to automatically detect the video source format and display the captured video in a window on your desktop.
