Product Features

  • Converts serial digital interface video for output to an HDMI display.
  • Supports 3G-SDI (3 Gbps), HD-SDI, and SD-SDI input on coax BNC.
  • For adding an HDMI screen to a high-end broadcasting or AV application.
  • Also has SDI loopout for a local SDI monitor or daisychaining.
  • Handles higher SDI bit rates of 2.97 Gbps (3G-SDI).
  • Autodetects SDI video standard on its 75-ohm coax input.
  • Supports 1080p HDMI video with Deep Color depth.
  • Reclocks SDI data for low-jitter video output.
  • Provides up to eight-channel audio support.
  • No software or driver installation required.


Essential for any professional video and broadcast engineering application, this handy converter enables you to connect a 3G-SDI, HD-SDI, or SD-SDI source for output on an HDMI display. This way, you can repurpose an ordinary LCD for video monitoring in your SDI setup.

The affordably priced device provides digitally pure SDI-to-HDMI conversion, ensuring no loss in the conversion for both video and audio signaling.

Use it in a TV studio, post-production, digital cinema, or AV application where you need to show uncompressed digital video from professional video equipment on a consumer-grade HDTV.

Even better, it features SDI loopout via a second coax connector. This way you can display a 3G-SDI signal from a camera on an HDMI panel while simultaneously outputting the 3G-SDI signal to a second SDI device for local monitoring. Or use the loopout to daisychain to additional SDI equipment.

The 3G-SDI/HD-SDI to HDMI Converter processes up to eight channels of audio, including 7.1-channel or 5.1-channel audio in addition to HDMI video. If your SDI source device supplies multiple channels of surround sound or Dolby® TrueHD audio, for example, the converter outputs the same number of channels for the HDMI connector's pinning.

For both older and newer SDI interfaces, the converter processes bit rates from 270 Mbps up to 2.97 Gbps.

Cable equalization helps compensate for loss when connecting the converter to an SDI source at maximum standard distances*.
