HDMI to Dual SDI Converter for Broadcast

The ESTONE HDMI2SDI converts a single HDMI source into two simultaneous SDI outputs for professional cameras, monitors and long-distance video distribution. It accepts HDMI 1.3a input with embedded audio up to 1080p 60 Hz and auto-detects SD-SDI, HD-SDI or 3G-SDI formats on each BNC port. The compact unit requires no external power supply and includes built-in ESD protection for reliable operation in studio or field environments.

Passive Cooling and Low Power Operation

The converter runs without a fan or external adapter, drawing power directly from the HDMI source for silent operation in noise-sensitive settings such as recording rooms or conference suites. Its circuitry maintains a 2.97 Gbit/s bit rate across both outputs, delivering full 10-bit conversion and synchronised 8-channel audio without added latency or heat buildup during continuous use.

Replaces Separate Distribution Amplifiers and Cables

This single box replaces a distribution amplifier plus multiple cable runs when feeding two SDI displays or recorders from one HDMI camera or switcher. The jump is worth it for crews needing 100 m 3G-SDI or 200 m HD-SDI reach without signal degradation, but it does not serve workflows requiring SDI-to-HDMI conversion or resolutions beyond 1080p.

Questions about this item

How do I connect the ESTONE HDMI2SDI converter to my camera and two SDI monitors, and what step do users often miss?

Connect the camera HDMI output to the Type A input using a standard HDMI cable, then run BNC cables from the two SDI outputs to each monitor; the step often missed is confirming the camera outputs one of the listed HDMI formats such as 1080P@50/60Hz so the converter can auto-detect and match the SDI signal.

What maintenance or replacement will the ESTONE HDMI2SDI need during long-term use?

The unit has no fan or moving parts and draws power from the included adapter, so routine maintenance is limited to checking the BNC connectors for corrosion and replacing the external power adapter if it fails; the built-in ESD protection helps prevent electrostatic damage to the internal circuitry.

What is the first limit I will hit when running the ESTONE HDMI2SDI continuously at 1080P 60Hz?

The converter supports a maximum SDI cable run of 100 meters at 3G-SDI (1080P@50/60Hz) before signal degradation becomes the limiting factor; the 2.97 Gbit/s bit-rate and automatic format detection remain stable as long as the cable length stays within that distance.
