HDMI to Dual SDI Converter

The Jansicotek converter transforms a single HDMI source into two identical SDI streams for broadcast or surveillance workflows. It accepts 1080p at 24, 25, 30, 50 and 60 Hz plus common 720p and PC resolutions, making it suitable for camera feeds, CCTV recorders or professional monitors that require SDI connectivity.

Build and connections

A single HDMI Type A input feeds two SDI outputs, allowing one source to drive dual displays or a recorder and a monitor simultaneously. The unit ships with a dedicated power adapter and operates as a compact plug-and-play module that can be tucked behind equipment racks or camera rigs without blocking adjacent ports.

Signal limits

Conversion is strictly one-way from HDMI to SDI; the device cannot pass SDI signals back to an HDMI display. Output formats are limited to 720p at 50 or 60 Hz and 1080p at the listed frame rates, so higher resolutions such as 4K or frame rates beyond 60 Hz are not supported. The interface runs at 2.970 Gbit/s, matching standard 3G-SDI bandwidth.

Questions about this item

What SDI standard does the 2.970 Gbit/s bit-rate limit the output to?

The converter outputs HD-SDI and 3G-SDI at 720p 50/60 Hz and 1080p 24/25/30/50/60 Hz, matching the 2.970 Gbit/s ceiling.

What power supply is included and what connector does the unit need?

A power adapter ships in the box and plugs into the converter's DC jack; no separate supply is required.

How is the converter installed and which step is often missed?

Connect HDMI source to the input, link both SDI outputs to displays, attach the supplied power adapter, then power on the source — skipping the power step leaves the unit inactive.
