AoIP Comes to IPR

Posted by Dave Sarkies on Feb 21, 2018 12:00:00 PM

Gary Langley is Chief Broadcast Engineer at Interlochen Public Radio, a service of the Interlochen Center for the Arts consisting of two radio stations featuring fine arts and public affairs programming for Northwest Lower Michigan and reaching into the state's Upper Peninsula. A relative newcomer to Audio over IP, Gary says learning the ropes of AoIP was simple thanks to a fresh Axia installation at IPR shortly before he came on. But it wasn't just a transition to AoIP for Gary—it was a transition to radio from the TV world. Gary tells us how Axia, AoIP, and VoIP have made his dual transitions easier than he'd have expected.

Routing Alternate Content the Wright Way

Posted by Tim Wright on Dec 6, 2017 12:25:00 PM

Many stations that carry sports programming—particularly pro sports broadcasts—are likely to be limited by league rules when it comes to streaming game broadcasts due to copyright regulations. As the flagship station for Chicago White Sox baseball and Chicago Bulls basketball, we are one such station here at WLS-AM in Chicago. Due to licensing restrictions of MLB and the NBA, WLS isn’t allowed to stream these teams’ games on their normal internet stream. Instead, alternate programming such as “Best of” editions of local or satellite-delivered shows—usually put together and aired by a producer in the control room—are routed to the internet stream.

To make the routing of the alternate content easier, I devised a solution using Axia Pathfinder. The only requirement is a spare PC capable of running Livewire audio drivers and VLC.

Slaying the Lost Packet Dragon with Pathfinder

Posted by Trevor Stuart on Nov 15, 2017 12:20:00 PM

Using IP radios as your STLs has many advantages. One disadvantage though is that they can be more susceptible to rain and snow fade than other STLs.

Using Axia Pathfinder and syslog, I’ve been able to keep my stations on-air, without hearing a dropped packet. Though I am using syslog, the same result can be achieved using SNMP. Even if the IP radio you have is not capable of sending syslog, you can still make this work for you with a little tweaking...

Untangling EAS with Pathfinder

Posted by Shane Toven on Feb 8, 2017 3:13:23 PM

For many years, broadcast stations have been required by law to incorporate emergency alerting into their air chains—usually directly in line with the program path as the last stage prior to the transmitter. As station groups have consolidated and air chains have become more complex, however, managing this insertion gets a bit trickier. What used to be a 1:1 correspondence between studios, transmitters, and everything in between is often now a matrix of possibilities including multiple studios or automation outputs, along with main and backup program paths and transmitters.
