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.

Timing is the most fundamental aspect of broadcast television. From the early days of tube cameras, to modern OLED displays, timing continues to play a crucial role for maintaining an optimal viewer experience. 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.
The IEEE Standards Association (IEEE-SA) has adopted the OpenFog Consortium’s reference architecture for fog computing. This may prove significant to broadcasters in the OTT era.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s, and in this article, we investigate microphones and how they are used in television.
The Cloud itself is pretty simple, but for broadcasters, leveraging it can be complex. It isn’t that difficult technically, but Broadcast still straddles requirements that demand real time, high resolution, quick turnaround solutions; and this is coupled with the need to connect geographically separate locations, reduce costs, and extend access to assets regardless of where the data is stored with multi-format distribution capabilities.
Cloud is undoubtedly one of the hottest topics in the broadcast and media industry at present, and if you were to judge the state of cloud adoption by the huge volume of noise around the subject, you could be forgiven for feeling like a dinosaur if you haven’t already fully embraced it.
Part one of this article, first published in the Journal of the IABM asks what’s the real state of play? We spoke to eight IABM members to find out what their end-user customers are actually doing now in the cloud, what they’re not, whether it’s public, private or hybrid, and where the future will take us. Are we truly heading towards a dematerialized industry, and if so, what’s holding us back today?
