Inside the HDBaseT 2.0 Specification, Part 1

Okay now in applications with the 2.0 spec, is this going to require shielded cable or are you still able to go with regular unshielded Cat-5, Cat-5/e, Cat-6 or whatever?

Cat-5/e and just like the first version. Another use case—I think this is one of the reasons USB 2.0 is so important—is if I take my flatscreen display in my bedroom, for example, again that’s connected to a switch and the switch is also connected to my PC—again somewhere downstairs or in the basement—I can select the PC as a source and with a single click, my TV or my flatscreen display on my wall turns into my PC. And since we’re sending USB as well, so with a wireless keyboard and mouse I can, of course, control it and work on it just like a regular PC. [Timestamp: 6:18]

Now with the 2.0 spec is there going to be any impact on the power-carrying capability of HDBaseT? Is that still going to be 100W to the full 320ft.?

No impact on the power capability. We’re still at 100W over 100 meters. [Timestamp: 6:32]

So now that you’ve had the 2.0 spec announcement and the initial wave of news about that, what’s the next step toward implementation?

The improvement and release of HDBaseT 2.0 specification is a very important milestone, which really leads the way to the development and release of HDBaseT 2.0 chips followed by HDBaseT 2.0 products. [Timestamp: 6:53]

So the manufacturers get onboard just like they did before and that seems to be a fairly rapid process.

Well they’re already involved. It was a joint work by all Alliance members, so manufacturers are really, most of them at least, are already involved. It’s not the first time that they’ve heard about it. [Timestamp: 7:11]

I was talking about power just a minute ago and we’ve had a lot of discussion generated about HDBaseT and the power spec and how much you can actually send over the line and to what distance. How much actual line loss are we talking about with PoH on say, a hundred meter run with Cat-5 or Cat-5e? Is there a significant power loss?

No, we don’t think it’s significant. We may encounter up to 10 percent line loss, which is pretty common, but really it’s still sufficient to power many TV models in the market. And I think that’s the reason everyone talks about the power of our HDBaseT feature because it’s such an amazing one. [Timestamp: 7:48]

And an especially handy feature for digital signage applications and using LCD displays.

There are already TV models with the power feature implemented, so they’re actually a single-wire TV, which is a great product. [Timestamp: 8:04]

Yeah, there have been a lot of those demonstrated at infoComm and it’s sort of strange seeing nothing but one twisted-pair cable going into the display. You have to sort of get used to that.

Yes. At industry shows and events we’ll be participating, people just stop at our booth, even if they didn’t hear about HDBaseT. They take pictures of the single-wire TV; they call their friends. They’re not used to seeing that, but they will get used to it. [Timestamp: 8:28]

Yeah, they were initially ducking about and trying to find the secret power cable somewhere.


And it’s a little strange but I still see articles online about HDBaseT being the so-called HDMI killer and replacing it, but that’s not really the case is it? It’s really a technology to be the missing link for HDMI to be able to carry it a useful distance in addition to the 5Play features.

Yes. We don’t see HDBaseT as a replacement of HDMI. We actually see it as a complimentary technology to HDMI. I mean HDMI is great for connecting your Blu-ray or anything else to your TV, of course when it’s in close proximity. Also, of course, you can find HDMI today in almost every TV and almost every device, so it’s there and it’s important. However, HDMI, as you said, just cannot go the distance that some use cases require. So I guess when you need more than a simple point-to-point closed connection or when you need greater distances, or like in HDBaseT 2.0 when you want to connect all your devices throughout the home, HDBaseT is the option for you. [Timestamp: 9:41]

Filling in the distance problem with HDMI and adding the 5Play features have really put HDBaseT on the map over past couple of years. Dana thanks so much for joining us for part one and in part two we’ll get into some more details on HDBaseT and the new 2.0 spec and what you can do with it. It’s been nice having you here.

Great. Thank you.
