The term, “metadata” may be one of the most misunderstood terms in the video business. It is often defined as, “data about data.” Even that phrase does not encompass the real value of metadata when it is combined with the latest production technology.
There’s been a lot of talk about the resource efficiencies related to remote operations for live production, but the cost of bandwidth to connect all of the disparate locations continues to make this way of working prohibitive for most second-tier producers.
Protecting media systems from hacking, malware and viruses are genuine concerns to every broadcast and production facility engineer. Unfortunately, antimalware protection software is seldom used on audio and video media systems because the two technologies often prove incompatible.
“May you live in interesting times.” The expression suggests there is more than one interpretation of the word interesting. There can be no doubt that the media industry is living in those interesting times as it tries to navigate its way through a radical change in the way media is delivered to and consumed by the end customer.
Audio is arguably the most complex aspect of broadcast television. The human auditory systems are extremely sensitive to distortion and noise. For IT engineers to progress in broadcast television they must understand the sampling rates and formats of sound, and in this article, we delve into digital audio.
Virtually every audio engineer experiences ground loop noise at some point in their working career. It can be caused by many things and happens at the least expected times. Here’s a guide to what causes ground loops and how to get rid of them.

Picture stutter and breakup are just a few of the symptoms of synchronization and timing errors.
Part One of this two-part series explored the various layers and protocols of ATSC 3.0 that broadcasters must understand to take full advantage of the opportunities available through the technology. This second and final installment explores best practices for signal verification and compliance across the ATSC 3.0 ecosystem.
