First it was HDBaseT and now HDBaseT 2.0 has made the news, and Dana Zelitzki of Valens is back with us for part two to get into the power-carrying capability, HDBaseT Class B and some other things on the horizon for Valens. That’s coming up next on the SVC Podcast.

SVC: Dana Zelitzki from Valens, coming to us all the way from Israel. And we’ve had an interesting time difference to work out, 5:00 in the morning in the Eastern U.S., so you’re probably a little more awake than I am.

Dana Zelitzki: Yes. I really appreciate it.

We’re talking about HDBaseT and the HDBaseT 2.0 specification. What are the various types of products so far with native HDBaseT, the devices that now have it built-in?

There are many products and in the beginning we really started mainly with HDMI extenders and various types of HDBaseT dongles, which were followed by matrices and switchers by the pro AV companies. But lately, in the past year or two, we’ve seen HDBaseT penetrating new types of products and devices like many projectors. Really we have lots of projectors from leading companies and we expect to see many more to come. We’ve started seeing HDBaseT in displays now; mainly for commercial uses but also in TVs for the homes. And just recently many HDBaseT AV receivers were introduced to the market from companies like Pioneer and Onkyo and Integra, so we expect to see more like that as well. [Timestamp: 2:03]

And those are all over the InfoComm YouTube videos and I saw that Epson just released, I think, three new projectors this summer with native HDBaseT and I think the company market its own HDBaseT transmitter box specifically for those projectors. Things are moving along with the Alliance. How many companies are now members of the HDBaseT Alliance?

As of today we have 66 member companies and counting. I think what’s unique about HDBaseT Alliance is not necessarily the number, although it is growing very, very quickly, but it is the combination—the mix of type of companies. I think we’re a unique alliance by having both leading pro AV companies and leading consumer electronic companies. This unique combination was specifically important in spec 2.0 development, for example. It enables us to address the needs of both markets. [Timestamp: 2:57]

And since there’s such a wide range of companies in that, you probably tend to get a lot of different opinions on things during the initial discussions because people are coming to it from quite different directions.


So when they get onboard, what does a company with a product have to do to be able to carry the HDBaseT logo on it?

So that’s a pretty simple process, actually. The first step is to become an HDBaseT Alliance member. Once you are a member, you have access to the compliance test specification so you know what to expect when you submit a product for testing and you can check it beforehand to see if it passes the testing successfully. The next step would be to send the product for testing with an Alliance-recognized testing facility. If you pass the test, congratulations and you can put the HDBaseT logo on. It was actually very important for the Alliance to make the testing procedure—the certification procedure—as simple as possible. [Timestamp: 3:55]

I’ve noticed that there are a number of manufacturers who have implemented the Valens VS100 and VS010 chip set but refer to the feature set with their own proprietary terminology.

That’s true, but it’s changing actually. And this is the main reason that it was so important for us to release the certification program because this is exactly what’s going to change that. The Alliance then, many HDBaseT products were out in the market very, very quickly and really before we had the certification program in place. So this is a process and it’s changing. Actually with the new type of products like the projectors and the displays, the compliance and interoperability is so much more important that we see that these manufacturers actually send the products for testing and certification even before the product is released. So when it’s out on the market, it’s already out there with an HDBaseT logo on it. [Timestamp: 4:54]

And of course at this stage of adoption one of the key words is interoperability. People see that it says HDBaseT but will it really work when I connect it to this other manufacturer’s hardware? Obviously, a big step when you get to where you know it will work and deliver all the features no matter what company name is on the case.

Exactly and this is really the purpose of the certification program, to guarantee products into operability and that products from different vendors will work seamlessly with one another. [Timestamp: 5:22]
