The HDMI Forum has just released the HDMI 2.0a spec, this is great news if you are a movie buff, or at least it will be in the coming months.

In a nutshell all the current 4K HDMI 2.0 TVs on the market wont support this change,¬†while new ICs wont necessarily be required, they could be to support all the features this new specification offers. So it might be worth delaying that TV purchase a bit longer….

The main reason for this specification release is to appease content creators and specifically the carriers of that content. The first and most obvious of those is the Blu-ray Disc Association (BDA), these guys have held off producing a 4K Disc for sometime now and it’s been clear to us that the reason was the lack of definition available in the HDMI 2.0 specification. Their (BDA) work with the CEA has been squarely aimed at getting the feature support they want. So that the media they want to release is as good (or as bad*) as they want to release.

Our products (including our USB-CEC Adapter) will already handle the HDMI 2.0a specification so anything you buy from us now or already own will remain cutting edge.

* Despite all the technical efforts truly dire movies can’t be made better with sharper graphics.

Introducing the Intel NUC HDMI-CEC Adapter!

So it’s been a long time coming and after much discussion with Intel we’ve managed to create an adapter that will work in the very popular Intel NUCs, instead of requiring 3.3V we’ve switched to using 5V removing the compatibility issue some customers have faced historically. We’ve also spent a great deal of time shrinking the board to fit inside the case.

This isn’t an easy problem to solve as the NUC although having a custom solutions header on the board doesn’t actually give any thought to how you might use it. In the end we’ve resorted to a double sided sticky pad that will hold it in place directly on the motherboard but without causing any electrical shorts or thermal issues.

If your wondering why the cable loom has larger connectors than needed on one end, you will be amazed to find out that despite our best efforts no-one seems to make a 2mm pitch 1×1 box header, the best we could find was 2×1. If our new adapter is popular then we promise to invest in tooling to develop a 1×1 box header. That said it should not cause you a problem!

We’re taking pre-orders right now, the initial batch size is limited so I suggest placing an order now if you want to guarantee one as soon as they become available later in April.

While quite a mouthful of a title for a blog post it does cut to the chase, thanks to the hard work of the LinuxMCE team they have let us know that they now directly support our USB-CEC Adapter and Internal HDMI-CEC Adapter in their home automation software solution! It works on all i386 platforms that LinuxMCE supports and the RaspberryPi too.



Sorry all for the downtime this weekend, we had to perform a server move on a rather unplanned basis. Services are now being restored, if you discover a broken link, please email

We are pleased to announce the latest update to our libCEC (Consumer Electronics Control) technology, this point release addresses stability issues discovered by our customers.

We advise all users to upgrade to the latest version which addresses a number of issues relating to standby and reconnection with one of our hardware products connected.

The latest update can be found on our USB-CEC Adapter product page.

We are pleased to report the issue concerning BBC iPlayer and no sound has now been resolved in the DTR-Z500HD and DTR-HD500 units, sadly we are unable to resolve the issue if it is affecting the DTR-HV250.

You can receive a firmware update via the Internet Software Upgrade option on your TVonics box, press MENU, then Service, and select Internet Software Update.

As some users are aware there is currently an issue on TVonics boxes (DTR-HV250, DTR-HD500, DTR-Z500HD) which causes the unit to crash and/or play no sound when accessing the BBC iPlayer service via the red button.

We are aware of this situation and working with the BBC currently to resolve the issue, the issue has arisen due to a platform change to the BBC iPlayer MHEG service. Both the BBC and ourselves are still trying to narrow down the exact cause of the issue, however we have found a temporary work around. You can find details about this on our forums here.

Please be assured we are doing everything we can to get this issue resolved for all customers at this time and hope to have an update out shortly.
