Datapath VisionAV-HD Triple Channel HDMI/DVI/RGB/YPbPr/SD/Composite Video Capture Card

The VisionAV-HD is a four lane PCI Express capture card with three video capture inputs - two supporting HD capture and a third supporting SD composite video, these three independent video channels can be captured simultaneously. The VisionAV-HD also adds multiple channels of audio capture, which can be synchronised in software using time stamping with all video capture channels.
