TWiRT 161 - Audio Reliability Over the Public Internet

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.

TWiRT 161 - Audio Reliability Over the Public Internet

TWiRT 160 - John Garziglia

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.

TWiRT 158 - Where's My Radio?

Could AM/FM radios disappear from new car dashboards in 2 or 3 years? That’s the word from an auto industry insider. Whether or not traditional radios disappear from autos, radio stations better be working on their digital delivery future.

Chris Tobin, Tom Ray, Chris Tarr, and Kirk Harnack raise the volume on discussing digital delivery platforms, apps, FM chips, and traditional radio listening.
