It escaped from the lab and now it can’t be stopped. HDBaseT, one of the biggest developments in pro AV now goes to the next level with HDBaseT 2. Chipset manufacturer Valens is at the forefront of HDBaseT and Dana Zelitzki is here from Valens to give us the latest on the new HDBaseT 2 specification. That’s coming up next on the SVC Podcast.

Dana, thanks for joining us on the SVC Podcast from Israel and Valens, the originating company and driving force behind HDBaseT. And we’re leading off with HDBaseT 2, the new spec that’s in all the AV news lately. Tell us a little about HDBaseT 2.0. What’s it all about and why all the hoopla about it right now?

Dana Zelitzki: Thanks. I’m happy to be here with you also. First of all, we’re excited about HDBaseT 2.0 as well. It is the latest specification released by HDBaseT Alliance and it’s the result of long development work by all HDBaseT Alliance members, so it’s really joint development of both leading professional AV companies and leading consumer electronics companies. And this is exactly what the purpose of the new spec is, actually to bring the HDBaseT user experience that the professional AV are already familiar with and are already accustomed to, to the mainstream consumers’ homes.

So this mainly impacts the residential AV market?

Well it does, of course, add improvements to the professional AV also in terms of performance and implementation. It will make the implementation of the equipment much simpler, and adds many features to it. But I think the big news, and this is why everyone is so excited about HDBaseT 2.0, is that we are really bringing HDBaseT to the consumers. [Timestamp: 2:21]

And with HDBaseT initially we heard a lot about 5Play and now we’re hearing about HomePlay. Is that a different feature set?

Well, yes. Of course we’re not neglecting the 5Play feature set. 5Play is the essence of HDBaseT, but we’re adding some features to it. From a technical perspective, we’re adding features such as networking capabilities, control point capabilities, switching capabilities. These will all enable true HDBaseT switching, unlike the first specification that really was focused on the physical link. Also the first specification was point-to-point connectivity standard. The second specification adds multi-point connectivity and multi-stream support. [Timestamp: 3:11]

I would think that the really big thing about this is the ability to go point to multi-point with HDBaseT now because this should bring in a whole range of new applications.

Exactly. So we’re actually enabling sending the entire 5Play feature set from any source to any display, including switching and multiple streams from multiple types. In addition, we’re adding integrated supports for USB 2.0 as well as other native interfaces. It is true that it was also available, in some way, in HDBase1.0, but now this is an inherent part of the chip set so that will make an HDBaseT switch smaller, less expensive, and simpler to implement. [Timestamp: 3:58]

How will the HDBaseT switches work? What sorts of specific applications are you going to be able to implement with these?

Let’s talk about the classic use case, or classic application, of an HDBaseT switch inside a home. Basically the HDBaseT switch is designed to provide all required services for a multimedia home, and let me describe the use case. Let’s say you have an HDBaseT switch in a home and it’s connected to all the sources that you have in the house; to your Blu-ray player, to your PC, your laptop, to your gaming platform, to anything—basically anything. And instead of having multiple devices in every room in your house, you can have all these devices connected to the HDBaseT switch tucked away in the basement or some communication cabinet. And from this switch, you’re connected by HDBaseT with a single Cat-5 cable to all the displays around the house. And with a simple control application that can be installed on your smart phone or tablet, you can select from any room in the house what source you’d like to use. Let’s say I’d like to watch a movie from my Blu-ray player. I can select it, I can control it since we’re sending the controls as well, I can pause it, go to the bedroom, continue to watch it from my bedroom and basically do whatever I want.
