HDBaseT™ 1.0 and HDBaseT™ 2.0 – What’s the Difference?

As you may already know, HDBaseT™ has become the industry standard for the transmission of Ultra HD video & audio, HDBASETEthernet, controls, USB and up to 100W of power over a single, long-distance, cable.

So, what are the differences between HDBaseT 1.0 and HDBaseT 2.0?

Let’s break it down:

Version 2.0 adds USB 2.0 support, which means no more need for running an additional extender for any USB devices.


touch-screen.jpgHow many people in the world own a smart phone? Just over 79.1%, as of the writing of this article. That’s only 198.5 Million People – and, I can make a pretty safe bet that almost 100% of the people reading this have a smart phone. One of the main features on a smart phone is the Touch Screen functionality, and probably the main reason why most people will never go back to the non-smart phone era. That touch screen technology is now on laptops, tablets, TV’s, commercial displays, digital signage, etc. So, unless you want to go back to non-touch screen devices, you would need HDBaseT version 2.0 to continue to use it.


no-more-latency.jpgLet’s face it, we are all impatient… just as soon as the internet got away from dial-up and was much faster, it shortly became not fast enough. If you were giving a presentation, how professional would you look if you were waiting for the system to catch up to you? If you’re in the technology industry, how much confidence are you instilling in your client for their new AV, IT or control system if your presentation is having issues with latency, stalling or unresponsive? HDBaseT 2.0 removes all past latency issues.


HDBaseT uses UTP or STP, so why does it need fiber support? If I’m already using the best cable for transmission, why would I want to use fiber? Currently in the AV and IT industries, Category cable is fine, but what about the medical industry or military? Looking at those markets, even the smallest amount of interference can cause huge problems. Currently, HDBaseT 2.0 runs 330ft on category cable – imagine the distances you can go with fiber, plus, there is no loss with a light signal.

300U.jpgComprehensive’s CHE-HDBT300U HDBaseT 2.0 Extender with USB can extend your uncompressed HDMI signal up to 330ft to a compatible display. This HDBaseT Extender features full 5Play and USB convergence allowing the transmission of Video, Audio, Control (Bi-Directional IR/RS-232), Power over Ethernet (PoE) and LAN serving (Ethernet). Supports HDCP 2.2 for video signals up to Ultra-high-definition 4k@60Hz (YCbCr 4:2:0), including 1080p@60Hz. With LAN serving connection and external digital and analog audio capability that gives users the convenience of additional audio connection. It also supports the connection of USB host and 2 USB device ports that can control the source on the sink side 330ft away. The transmitter or receiver can be powered by the 24V@1A PoE function with only one power cable, allowing for greater flexibility in installations.


Just as HDMI 2.0 created the ability to send multiple video streams from one port over one HDMI cable, HDBaseT can now take those multiple video streams and continue the run without killing one of the streams. So essentially you started with two video streams and after everything is connected you still have two video streams at the other end.


The ability to daisy chain devices, rather than using full setup for each display makes a system not only less expensive, but also more flexible. The cost savings alone is a huge benefit.


4k-uhd.jpgHDBaseT 2.0 can handle of all the different levels of 4K, as you can imagine 4k@60 4:4:4 is currently the highest resolution you can get before we make the jump to 8K.

And there you have it! Everything HDBaseT 2.0 you need for the long-distance signal traveler…
