The Gefen EXT-3GSDI-2-HDMI1.3S Scaler enables broadcast quality content scaling to complement any HDTV resolution, an inexpensive way of viewing 3G-SDI content from a network. View 3G-SDI video directly from a 3G-SDI network on any hi-def display complete with digital and analog audio.

How It Works

Scale or convert 3G-SDI sources with the Gefen 3G-SDI to HDMI Scaler. A wide variety of image processing functions are provided by the on-screen menu that easily enables intuitive adjustment including color balance, brightness, contrast and other options to create the best possible video output signal.

Local 3G-SDI output for each of the two 3G-SDI sources permits connection to additional 3G-SDI products on a network. Alternatively, it can be used for viewing on 3G-SDI based monitors prior to processing an HDMI signal conversion.
