Epiphan AV.io HD+ and AV.io SDI+ USB Capture Cards

The AV.io+ capture cards turn a video source into a USB webcam that any application already knows how to open. They are UVC devices, so there is no driver to install and no vendor software to fight with: plug the card into a Mac, Windows, or Linux machine and the source appears in Teams, Zoom, OBS, Wirecast, or whatever else is running. Two models cover the two common connector worlds. AV.io HD+ takes HDMI or DVI sources; AV.io SDI+ takes SD-SDI, HD-SDI, and 3G-SDI, and captures the embedded audio with the picture.

Both capture at up to 1080p and run 60 fps at any resolution unless the host application asks for something slower. The card scales automatically to whatever frame size the application requests, from 320 x 240 up to 1920 x 1200 at 5 to 60 fps, and by default preserves the source aspect ratio by pillarboxing or letterboxing rather than stretching the image. That matters when the source is a laptop or a medical scope running an odd resolution. USB 3.0 SuperSpeed is the intended connection; a USB 2.0 port will still work at reduced performance, but without audio capture.
