ESTONE HDMI2SDI Video Converter

The ESTONE HDMI2SDI converts a single HDMI source into two simultaneous SDI feeds. It accepts HDMI 1.3a input up to 1080p at 60 Hz with embedded audio and outputs 3G-SDI, HD-SDI or SD-SDI signals automatically. The unit is aimed at broadcast, security and AV installers who need reliable long-distance signal distribution.

Upgrade From Short HDMI Runs

This converter replaces direct HDMI cabling when the signal must travel beyond typical copper limits. It supports 3G-SDI transmission up to 100 metres and HD-SDI up to 200 metres without repeaters. The jump is worth it for fixed installations such as studio floors, auditoriums or camera chains where HDMI drop-outs or length restrictions make a direct connection impractical.

Plug-And-Play BNC Installation

The box requires no external power supply and draws power from the HDMI source, so setup is a single cable from the camera or switcher and two BNC cables to the displays. Common issues are mismatched frame rates — ensure the source outputs one of the listed 1080p or 720p modes — and loose BNC connectors, which can interrupt the clock detection that auto-selects the SDI standard.

Questions about this item

What HDMI connector type does the ESTONE HDMI2SDI use for its single input?

It uses a standard HDMI Type A connector for the single input.

Does the converter require an external power supply, and what is the first step after connecting cables?

No external power supply is needed; the unit draws power from the HDMI source, so the first step is to ensure the source device is powered on before expecting SDI output.

How many BNC SDI output ports are on the unit, and what SMPTE standards do they follow?

The converter has two BNC SDI outputs that auto-select between SD-SDI, HD-SDI and 3G-SDI following SMPTE 259, 274, 292, 296, 372, 424 and 425.
