Artificial Intelligence (AI) was a hot topic of both conversation and display at this year’s NAB show. While the early demonstrations merely hint the potential of AI, there is clearly plenty of interest by users and manufacturers. Artificial Intelligence is being compared to and with Machine Learning (ML).

An in-depth article by The Broadcast Bridge Editor, David Austerberry, helps clear the confusion and hints at the benefits of these technologies in media production and playout.

This week’s second article highlights the second of a three-part series on audio over IP technology. Surprising to many video engineers, the telco’s have been distributing broadcast signals using IP networks for many years without us being fully aware. Gateways, are used to provide the necessary format translation from SDI, AES, or analogue, to IP. The underlying network remained hidden from most broadcasters.

Now that IP is central to broadcast facilities, engineers need to better understand how Layer-2 switching and Layer-3 routing operates, and how these relate to the Open Systems Interconnect (OSI) model. The Broadcast Bridge Technology Editor and consulting engineer, Tony Orme, provides a deep technology discussion on moving IP through production and broadcast facilities.

Deep learning is a technique for machine learning, one way to achieve artificial intelligence.

Many new software applications now claim Artificial Intelligence (AI) or machine learning as their underlying power. But is this just marketing hype, or is AI going to be really useful technology for the media and entertainment sector?

AI is not new, it’s been around for half a century or so, but it is only in the last couple of years that the term has been cropping up in product descriptions. And for an industry that prides itself on creativity, it may seem an anathema to automate processes with smart machines. Yet, there are many areas of the media business that can benefit from AI.

The article, “AI: Real or Hype?” will help you better understand more about AI and how it may benefit your workflows and productivity.

To fully leverage the benefits of IP networks we need to think in IT terms. Just replacing the acronym MADI or AES with IP is insufficient as all we end up with is a very complex, poorly utilized, static network.

It doesn’t help that broadcast engineers refer to signal switching devices as routers, such as an SDI router or audio router. The terminology becomes even more challenged as Layer-2 switches sometimes incorporate Layer-3 routing functionality. These switches are often referred to as multilayer switches. Confused?

Need help in getting from SDI to IP?

See that hill up ahead? It’s not a hill, it’s Mt Everest and your job is to conquer that mountain. Rendered into familiar industry vernacular, you, video engineer, are charged with building an IT-centric facility. A SMPTE standard was just approved, so what’s taking you so long?

The book, “Building IP Media Facilities – Keys to Migrating from SDI,” is a video engineer’s guide to transitioning from digital SDI infrastructures to IT-centric facilities. The book is comprised of 15 chapters focused on key operational aspects of IT and IP terminology, networks and ‘how-to’ practical discussion.
