Description
Model 2271 is a USB 2.0 HD video capture device. It accepts SDI, DVI, and composite video. It captures uncompressed SD or scaled down HD video and will compress resolutions up to 1080p30 (from one of 3 inputs at a time). It can simultaneously send both compressed and uncompressed video to the host computer.

Software
The unit is a fully compliant UVC (USB Video Class) device that works with any standard UVC driver, thus eliminating the need for a custom driver and allowing seamless control through video APIs such as DirectShow and Video4Linux.
Free Linux and Windows software development kits (SDKs) are available for model 2271. The SDKs include our versatile high-level API with popular functions such as snapshot capture, recording to files (in AVI, MP4 and TS formats), overlay management and, to facilitate styled text, functions for drawing Unicode text on video overlays. Also included is a comprehensive demo program that shows off the device's full capabilities, complete with source code that serves as an ideal starting point for custom applications.
Packaging options
Model 2271 is available as a bare board (2271) or as an enclosed unit (2271S).
