Instant Capture and Display

Many video applications demand the highest level of accuracy. Video needs to not only be captured for storage or processing, but also needs to be seen in real time by professionals in cutting edge events. Datapath’s VisionIO range of capture cards offer the ability to capture high quality video and loop inputs directly to outputs, creating latency at just a few pixels. Signals are delivered to the primary display, even if the host PC stops functioning.

Zero Latency Overlay

The VisionIO series also offers an on-board alpha blending capability, allowing a secondary source of frames to be overlaid on to the outgoing display in real time. The optional use of an overlay watchdog ensures that the application supplying the overlay is in constant control. If any problems are detected the card will ensure the integrity of the primary signal by preventing the overlay from obscuring the live signal.

Video Streaming

DirectShow drivers for WDM Streaming support the following applications, to encode, record and stream video over networks or the Internet:

• Microsoft Media Encoder®
• VLC
• VirtualDub
• Any other DirectShow encoding software

For streaming applications, the VisionSC-SDI4 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 VisionIO due to the built-in WDM support.
