Product Code: EXT-HDMI1.3-2-3GSDI


Convert HDMI 1.3 into SD/HD/3G-SDI at 1080p/60 Hz with L/R analog audio

The Gefen HDMI1.3-2-3GSDI Converter takes an HDMI input signal and converts it to SDI/HD-SDI/3G-SDI output format (either SDI standard definition, HD-SDI high-definition, or 3G-SDI high-definition with ultra high bandwidth). Converted HDMI signals are mirrored onto two identical SDI BNC outputs. A single pair of RCA-type L/R analog audio output jacks enables monitoring of embedded HDMI audio via an external analog amplifier or receiver.

LED indicators on the front and bottom of the unit provide HDMI and SDI signal status and troubleshooting assistance in the event of errors.

How It Works

An HDMI source is connected to the HDMI input on the HDMI 1.3 to 3GSDI Converter. An SDI device is connected to the SDI outputs on the Converter. The included power supply is connected to the HDMI 1.3 to 3GSDI Converter. When the HDMI source and the HDMI 1.3 to 3GSDI Converter are connected and powered on, audio/video signals are converted to the proper format on connected A/V output devices (displays, audio receivers).

DIP switches on the underside of the unit allow presetting critical functions inside the Converter such as 3G Mapping Level, Test Pattern and RGB Range.

Three (3) LED indicators on the front panel indicate the presence of data rates up to 3G-SDI, the presence of locked-on HDMI, and power to the unit.

Note:  In accordance with the HDCP specification, encrypted HDMI signals will not be converted to SD/HD/3G-SDI formats.

PC video input formats are not supported. This device does not scale video. Only SMPTE formats are supported when using the SDI outputs; PC formats will not be converted.
