SDI2USB 3.0 Overview 1. SDI2USB 3.0 Overview SDI2USB 3.0™ Epiphan's newest external frame grabber uses an SDI input connection to transmit data to a video capture workstation through a USB 3.0 port or a USB 2.0 port. The video capture workstation can capture, record and broadcast uncompressed production-quality images and videos directly from 3G-SDI, HD-SDI and SD-SDI sources. Both audio and video capture is supported and no peripheral component interface (PCI) is required. SDI2USB 3.
Figure 1 SDI2USB 3.0 sample configuration including confidence monitoring The SDI2USB 3.0 frame grabber is fully compatible with DirectShow on Windows, Video4Linux on Linux, and QuickTime on Mac OS X. SDI2USB 3.0 is part of Epiphan’s complete line of video and audio signal capture products. For more information about all Epiphan’s video signal capture products, refer to Frame Grabbers Overview on Epiphan’s website. 1.1 Package Contents Epiphan SDI2USB 3.0 device package includes the following: 1.

Note: the SDI output port is active when the SDI2USB 3.0 is connected to a powered up video capture workstation running the SDI2USB 3.0 driver. 4 SDI Input Connect an input source with an SD-SDI, HD-SDI or a 3G-SDI signal. 2.2 USB 2.0 Backwards Compatibility SDI2USB 3.0 is USB 2.0 backwards-compatible; you can connect it to the USB 2.
Physical Attributes High speed data transfer (up to 5 GB/s) is supported by USB 3.0 when you connect your SDI2USB 3.0 to the USB 3.0 port on the video capture workstation. This section describes compatible connectors and cables. 2.3.1 USB AM-BM Cable The USB AM-BM cable connects the SDI2USB 3.0 frame grabber to the USB 3.0 or 2.0 port on the video capture workstation. Figure 4 USB AM-BM cable 2.3.2 SDI to SDI Cable Connects an SDI source to the SDI2USB 3.0 SDI in port.
System Requirements Figure 5 SDI to SDI cable 3 System Requirements Epiphan’s SDI2USB 3.0 frame grabber requires the following hardware and software: Video source any SDI video source Video capture workstation compatible USB 3.0 host controller for SuperSpeed operation; USB 2.0 controller for High Speed operation.
Getting Started available from the Software Download page. 3.1 USB 3.0 controllers To take advantage of the high transfer rate of USB 3.0, ensure your video capture workstation is equipped with an adequate USB 3.0 controller capable of supporting the transfer rate. This is especially important when capturing high-definition video and large audio files, and capturing 60 fps. Epiphan recommends the following USB 3.0 controller. Linux requirements: kernel version 3.5 or later (Ubuntu 12.
Installing SDI2USB 3.0 on a video capture workstation running Windows 3. Install the Epiphan drivers and capture software for the SDI2USB 3.0 on the video capture workstation. These procedures are specific to the workstation OS and are explained in the following chapters. 4. Connect the SDI2USB 3.0 to the video source. Refer to Connecting SDI2USB 3.0. 5. Connect the SDI2USB 3.0 to the video capture workstation. Refer to Connecting SDI2USB 3.0. 6.
Installing SDI2USB 3.0 on a video capture workstation running Windows 5. Unzip the downloaded file. Right-click on the .zip file and choose Extract All. 6. Run the Setup Utility (setup.exe) and follow the prompts to install the software. 7. The Windows drivers and Epiphan Capture Tool is now installed. 5.2 To upgrade to the latest Windows software version From time to time Epiphan releases new versions of Epiphan capture software available from the Epiphan web site.
Mac OS X Video Capture Workstation Installation 5.4 Troubleshooting a Windows Installation If you experience any difficulty viewing captured images with the Windows capture application, review the following items prior to contacting technical support. If the capture application cannot find the frame grabber: • Confirm that the frame grabber is connected to a video capture workstation USB port and has power connected and the device LEDs are lit. • Disconnect and re-connect the frame grabber.
Mac OS X Video Capture Workstation Installation 1. Find the latest Mac drivers and application software. Browse to http://www.epiphan.com/products/dvi-frame-grabbers/sdi2usb-30/downloads/ and scroll down to the Mac section of the download page. 2. Download the latest version of the drivers and application that will run on the video capture workstation. Make sure you note the download destination folder. 3. Double-click on the .dmg file to unpack it if it does not unpack automatically. 4.
Linux Video Capture Workstation Software Note: Some versions of the SDI2USB 3.0 user interface do not install a shortcut on the Mac OS X desktop. You can drag the Epiphan icon from the Applications folder to your desktop or add it to the Dock after installing a new version of the SDI2USB 3.0 user interface. You may also need to delete older versions of the Epiphan icon. 6.4 Finding Software Updates To find the latest versions of all Epiphan software and drivers for Mac OS X, browse to http://www.epiphan.
Linux Video Capture Workstation Software 7.1 The Epiphan USB Device Driver The Linux Epiphan USB device driver receives images from an Epiphan SDI2USB 3.0 and delivers the images to the Epiphan capture API and to Video4Linux. Before delivering the images the Epiphan USB device driver also performs image adjustment to improve the quality of the image. Image adjustments include setting the sampling phase, PLL adjustments, and horizontal shift.
Connecting SDI2USB 3.0 7.3 The Epiphan Capture API The Epiphan capture API also receives captured images from the Epiphan USB device driver. The Epiphan capture API is optimized for processing Epiphan SDI2USB 3.0 captured images. The Epiphan capture API analyzes individual images, performs on-device cropping, and handles video mode changes. The Epiphan capture API is an alternative to using Video4Linux to capture images on Linux video capture workstations.
Windows Capture Application 4. Connect the SDI2USB 3.0 to the video capture workstation by connecting the USB AM-BM cable from the SDI2USB 3.0 to the workstation’s USB 3.0 or 2.0 port.
