What’s HDBaseT?

HDBaseT is a technology created for long-distance AV signal transmission and distribution. It’s now a global standard for audio, visual, controls, and USB signals transmission (and reception) & Ethernet connectivity.

How Does HDBaseT Work?

Just like an HDMI balun, an HDBaseT HDMI extender contains two main units – a transmitter and a receiver.

Audio, visual, controls, and USB signals are received by the HDBaseT transmitter on the source device end and transferred through the category twisted pair cable; the receiver would be placed near the displays and peripherals. It’s responsible for converting the CAT signals back to HDMI and USB and sending them over to electronic devices.

HDBaseT technology is able to transmit

  • Uncompressed high-definition video (up to 4K@60hz 4:4:4 for Spec 3.0)
  • High-quality audio data (such as Dolby Atmos), USB (2.0 standard)
  • Control signals (IR, RS232)
  • Ethernet (up to 1Gbps)
