The VisionSD4+1 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/Data Wall Controllers

RGB Streaming
For streaming applications, the VisionSD4+1 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 VisionSD4+1 due to its
built-in WDM support.
VisionRGB Software:
The VisionSD4+1 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 VisionSD4+1 application to automatically detect the video source format and display the
captured video in a window on your desktop.
Hardware Overview:
The VisionSD4+1 has five complete capture channels supporting a single channel for up to 1920x1080
DVI or 2048x1536 Analog resolution, plus four SD analog capture channels.
The VisionSD4+1 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 VisionSD4+1 transfers the data directly to the graphics card
thereby increasing performance. The VisionSD4+1 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 Datapath graphics card, the VisionSD4+1 sends the data
to system memory or direct to the graphics card, dependant on the software used for display.
