Well, NAB is hardly what you’d call “free.” But Chris Tobin and Kirk Harnack were there, and were able to spend a little time scouting the Central Hall where most of the radio industry manufacturers are.
Chris Tarr joins us from NOT NAB – in Mukwanago, Wisconsin – where engineering life is good.
We’re dishing’ on NAB – some new products and the state of affairs we call “radio.”
What’s new at NAB? What equipment, software, and services will engineers be asking about? Chris Tobin, Tom Ray, and Kirk Harnack discuss these and other NAB Preview subjects.
One of the challenges in transferring audio programming over IP networks, especially over the Public Internet, is data loss caused by two factors: congestion-related packet loss and varying latency or jitter.
IP links may drop packets for several reasons; though some transmission protocols are designed to mitigate or correct such losses, they require extra bandwidth and extra time to make these corrections.
In this episode we examine several data transmission error mitigation techniques in the context of their application to real-time, low-latency IP-audio transport. We suggest how different techniques may be applied to different data loss or jitter scenarios.
Legal matters in broadcasting both frame and dictate the way we work. On this episode of TWiRT, John Garziglia joins us to talk about the legal, process, and practical sides of FM translators and more.
John is a Partner in the Washington, DC, office of Womble Carlyle Sandridge & Rice, representing radio and television broadcasters with Federal Communications Commission and communications law matters. John was formerly a broadcaster, working in the industry in St. Louis, Washington, D.C., and several smaller markets. John represents many broadcasters large and small with regard to questions that arise in the day-to-day operations of stations. He is a frequent speaker at both national and state broadcaster conventions.
He was instrumental in the creation of the Class C0 FM class.
He’s also a big proponent of translators for AMs and recently caused a bit of controversy by saying many LPFM people were “hobby broadcasters who would like to play radio.”
John fills us in on recent FCC translator matters, including the so-called “Tell City Waiver” and the “Mattoon Waiver.”
We also get to talk about John’s favorite ride – a Tesla Roadster.
In radio industry news this week: More IP-Audio products on the markets. Talk show call screening and social media get on the same User Interface. More cameras in radio studios. The Sequester will stop FEMA-IPAWS reps from talking with broadcasters at NAB. And, meet Jake Bechtold. He’s another up-and-coming radio engineer who started in IT. Jake represents the next generation of engineers who approach radio from an IT perspective.
Chris Tobin and Tom Ray join me to chat with Jake about radio engineering, and the news of the week for radio engineers.
