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. You can use the Epiphan software development kit (SDK) to create
custom video capture applications to record captured images from the Epiphan
capture API.
7.4 V4L Custom Video Capture Applications
Epiphan does not provide a video capture application for Linux. However, you can use
Video4Linux-compatible applications to perform many video capture operations such
as recording images or video, copying, printing and saving images, or broadcasting
images over the Internet. You can also use the Epiphan Linux SDK to create your own
custom video capture application. The SDK along with some example applications is
available from the products Downloads page (
http://www.epiphan.com/products/dvi-
frame-grabbers/dvi2usb-3-0/downloads/).
8 Connecting SDI2USB 3.0
This section describes how to connect an SDI source and video capture workstation to
the SDI2USB 3.0. Ensure the Epiphan capture software is installed on the video
capture workstation before connecting the SDI2USB 3.0.
1. Connect the SDI2USB 3.0 to the video source.
2. Connect an SDI source directly to the IN port on the SDI2USB 3.0 using the SDI
cable included in the package.
3. Optionally, connect an external monitor, for confidence monitoring, to the OUT
port on the SDI2USB 3.0 using a standard SDI cable.
