The GefenPRO GEF-HDVI-2-3GSDIS 3GSDI Scaler for HDMI and DVI converts both HDMI and DVI to single-link or dual-link SDI / HD-SDI / 3GSDI formats. Resolutions can be scaled up to 1080p Full HD, 1920 x 1200, and 2K. Genlock frame synchronization and up to eight channels of audio are supported.

The GEF-HDVI-2-3GSDIS provides high-performance scaling plus adaptive video interlacing with edge interpolation, advanced noise reduction, alpha blending, image enhancement, and a fully-integrated menu system. It also supports SDI, ED-SDI, HD-SDI, and 3G-SDI SMPTE formats. The built-in S/PDIF coaxial output can be used to send digital audio to a separate A/V receiver.

The GEF-HDVI-2-3GSDIS 3GSDI Scaler for HDMI and DVI provides superior 3G-SDI video packaged in a single-rack mount 1U tall unit with an internal power supply.

How It Works

Use the included cables to connect up to two Hi-Def sources, one with an HDMI output and another with a DVI output, to the GEF-HDVI-2-3GSDIS 3GSDI Scaler. Two HDMI or two DVI sources can also be used by connecting HDMI-to-DVI or DVI-to-HDMI adaptors. Connect coaxial cables from the BNC video output connectors to downstream SDI equipment such as processors and displays. If synchronization between other SDI components is desired, use another coaxial cable to connect an external clock to the Genlock BNC connector. Connect a digital audio cable between the S/PDIF connector on the scaler and an A/V or audio receiver. To control the scaler using RS-232, connect an RS-232 cable between the scaler and the RS-232 automation device such as the Gefen EXT-PACS or GTB-MINI-PACS. Connect the included AC power cord to the scaler and an available electrical outlet. Apply power to the source, the display, any other associated equipment, and the scaler. Use the included IR remote to control the scaling features via the built-in on-screen menu system.
