The VisionRGB-E2S, a stand alone PCI Express x4 plug in capture card, delivers extreme performance with 650MB/s transfer bus bandwidth providing a further improvement to the 480 MB/s of the VisionRGB-E2. This video capture has two complete capture channels supporting up to 1920×1200 DVI or 2048×1536 Analog resolution.
The VisionRGB-E2S 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 Datapath graphics card is used, the VisionRGB-E2S capture card transfers the data directly to the graphics card thereby increasing performance. The VisionRGB-E2S 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 Datapath graphics card, the VisionRGB-E2S sends the data to system memory or direct to the graphics card, dependant on the software used for display.
The VisionRGB-E2S capture card is an ideal solution for applications require the capture of Analog or DVI sources in real time. Typical applications include:
For streaming applications, the VisionRGB-E2S 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 VisionRGB-E2S video capture card due to its built in WDM support.

DirectX WDM streaming driver supports the following applications, to encode, record and stream video over networks or the Internet:
For further details see the Datapath DirectShow SDK documentation supplied as part of a typical installation.
The VisionRGB-E2S capture card is supplied with a powerful software application for configuring timing and format of the input sources and displaying the data. Simply connect your external DVI or Analog source into the card, run the VisionRGB-E2S application to automatically detect the video source format and display the captured video in a window on your desktop.
