HDMI to Dual 3G-SDI Converter

The ESTONE HDMI2SDI converts a single HDMI 1.3a source into two simultaneous SDI outputs, supporting SMPTE 259, 274, 292, 296, 372, 424 and 425 standards. It handles input resolutions from 480i up to 1080p at 60 Hz with embedded 8-channel audio. The unit requires no external power supply and includes built-in ESD protection for reliable operation in professional video workflows.

Integration Into a Broadcast Chain

Connect cameras, switchers or playback devices via the HDMI Type A input and feed two SDI monitors, recorders or transmission links from the dual BNC outputs. Automatic detection selects between SD-SDI, HD-SDI and 3G-SDI to match the incoming signal, while the 2.97 Gbit/s bit rate preserves full 10-bit colour depth. The compact 5.83 x 4.49 x 2.44 inch enclosure fits easily into rack drawers or portable kits.

Upgrade From Single-Output Adapters

This converter replaces basic HDMI-to-SDI dongles that offer only one BNC port, eliminating the need for a separate distribution amplifier when feeding two destinations. The jump is worth it for crews who regularly split a camera feed to a recorder and a director’s monitor, or for fixed installs driving a local display and a long-haul fibre link up to 100 metres at 3G-SDI or 200 metres at HD-SDI.

Questions about this item

Does the HDMI2SDI converter need an external power supply to run continuously?

No, the unit draws power from the HDMI source so no external adapter is required for all‑day operation.

How much heat or fan noise does the HDMI2SDI produce during extended use?

The converter has no fan and runs cool because it is powered directly from the HDMI input, so it adds no audible noise or noticeable heat.

What cables and displays must I already own to use the HDMI2SDI?

You need one HDMI Type‑A source cable and up to two BNC‑terminated SDI cables connected to SD‑SDI, HD‑SDI or 3G‑SDI monitors.
