What are the challenges of distributing 4K or 8K video?
By David Aleksandersen 14. March 2019
“4K video delivers stunning beauty and resolution. But like most new technology, it comes with challenges to overcome as well.” These were the opening sentences of a Crestron white paper, published in 2014. Now it says 2019 on the calendar, and we have a wide range of display technologies with 8K resolution. Are we ready to rumble or are we stuck with the same challenges?

Network basics for media server operators
By David Aleksandersen 13. December 2018
We live in a networked world – more and more services and products use networks for communication and content distribution. Do you need to be an IT engineer to be able to do network setups for your AV installation? Absolutely not.
If you rewind just a few years, sound, audio and lighting devices had their own, dedicated, communication connectivity. Not only did they have dedicated protocols, but also physical cables and connectors. What's more, inter-operability between these technologies was not a focus – neither for the users nor the developers. And IP (Internet Protocol) based networks were for the IT world, a completely different realm from the world of AV. But this is about to change.
You don't need to be an IT engineer to do AV networks, but you really need to have some key network skills. In this blog post, we take a look at the following topics:

What are genlock, framelock, & timecode sync and when do I need them?
By David Aleksandersen 27. September 2018
In the world of professional video and audio production, maintaining a synchronized signal across multiple units, such as video cameras, screens, LED walls and multi-projector installations can be the difference between success or… disappointment (putting it mildly!).
So how can you synchronise the video signals coming out of different sources? In this blog, we take a look at genlock, framelock and timecode sync.

What is MPCDI?
By David Aleksandersen 16. August 2018
We all love an acronym and here's one that seems to be popping up more and more. MPCDI is a standard format for multi-projector alignment systems, allowing full integration among a range of devices, programs and display systems. But what does that mean in reality, and why are industry standards important?
In this article, we’ll cover the following topics related to Multiple Projection Common Data Interchange (that’s MPCDI to us!)

Getting ready to invest in a media server? Take your time, because choosing the right solution for your application requires careful thought and consideration. And before you do anything, you need to tackle the central issue: should you build your own media server or opt for a pro off-the-shelf unit? In this blog post, we take a look at some of the key factors to keep in mind before making the final call.

4K, 8K, 16K – the race for higher resolutions is on!
By David Aleksandersen 14. June 2018
We have embraced 4K, and while some are still struggling to get on top of the challenges that 4K brought, several manufacturers are gearing up for 8K resolutions – and beyond! What are the benefits and challenges of higher resolutions? What products are there in the market?
In this blog, I’ve taken a look at the race for higher resolutions, and sounded out two projector manufacturers, Barco and Digital Projection, as they ramp up for 8K.
