3G-SDI to HDMI 1.3 Scaler, Gefen EXT-3GSDI-2-HDMI1.3S


Convert 3G-SDI to HDMI with scaled video and separate multichannel S/PDIF digital audio output

View 3G-SDI video directly from a 3G-SDI network on any hi-def display complete with digital and analog audio.

Gefen's 3G-SDI to HDMI1.3 Scaler enables broadcast quality content scaling to complement any HDTV resolution, an inexpensive way of viewing 3G-SDI content from a network.

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. The unit can be synchronized to other television picture sources utilizing the genlock reference signal input jack on the rear panel. (This supports both tri-level and blackburst methods of genlock.)
