Can I Use You as a Reference?

Everyone knows a bad reference can cost you a promotion or a job opportunity, but it can also be the source of frustrating intermittent television audio problems.

The widespread use of embedded SDI signals in lieu of discrete AES I/O makes dealing with clock reference a bit easier since the reference is an inherent part of the SDI bundle, but it doesn’t eliminate clock-related issues altogether.

xNodes Mark the Spot on Florida's Gulf Coast

Fans of public broadcasting outlets PBS and NPR living in southwestern Florida are served by WGCU, where the TV-FM public broadcaster has operated from the campus of Florida Gulf Coast University in Fort Myers for two decades. The station's Director of Engineering, Kevin Trueblood, has likewise been in the broadcast industry for 20 years, though only the last two of those years have been spent at WGCU.

Make a Proper IP Address Scheme for Your Livewire Facility

Want to get started quickly and correctly with your new Livewire facility? Axia Support Engineer Jeff McGinley offers up an important tip for optimal operation.

One of the first things to consider when planning your Livewire installation is a proper IP address scheme. We recommend reserving a small block of IP addresses per studio, and then assigning the same IP address to identical devices.

5 Tips for Converting to an AoIP Studio

If you’re a general manager, considering an Audio over IP network for your facility makes sense. The technology is faster, cheaper, and better than previous methods to build broadcast facilities. By converting to AoIP, you not only tap into the power of current technology, you allow your facility to leverage the enormous universe of “off the shelf” IT devices that are used worldwide, and not just in the broadcast industry. Here are our top five considerations for general managers thinking about a move to Audio over IP. 

TWiRT 340 - War Stories with Robbie Green

Move 4 radio studios across town.  You’ve got two weeks.  Go!  Oh, and scrounge some equipment to make the STL systems work with an old T-1 circuit.  And, find some time to replace seven FM transmitters with new, solid-state units and full HD Radio. That’s the world of engineer, Robbie Green. Robbie joins Chris Tobin and Kirk Harnack on This Week in Radio Tech.

Hosts:

Chris Tobin, IP-Solutionist
Kirk Harnack, The Telos Alliance, Delta Radio, & South Seas Broadcasting

Audio Monitoring Within the Transition to AoIP

As signal chains have become increasingly complex, the challenges involved in managing and monitoring these paths have multiplied exponentially. Over the past few decades, we've migrated from handling a single channel of content using composite video and analog audio pairs, to elaborate multi-channel facilities routing HD video with embedded audio over SDI or in many cases discrete AES pairs. These audio signals are often a mix of 5.1 and stereo programs and in many cases encoded to or decoded from Dolby® at some point in the chain.

25-Seven Launches TVC-15 Broadcast Audio Watermarking Monitor

The Telos Alliance this week announced the launch of the 25-Seven TVC-15 Broadcast Watermark Analyzer & Monitor, the first modulation monitor for watermarking. With TVC-15, radio stations in electronically measured markets can now monitor how each element in their programming supports audio watermarking.

Measurements happen in real time, without the need of a watermark encoder. Every 400 milliseconds, TVC-15 detects watermarks in any audio you feed it. This could be your own station's audio, or that of a competing station in your market. You can monitor any source, live or recorded.

Saving Sounds from the Dumpster

As the Twentieth Century is rapidly receding in the rear-view mirror, historians, archivists and collectors furiously gather artifacts and documents before they all disappear. Forgotten by many, but not all, are the soundscapes of the past; both technological and natural in origin.

If you've worked in radio long enough, you already know something about changing soundscapes. The clattering of a teletype machine in the newsroom, the sound of records and reel tapes being cued and the once per second chunk-chunk-chunk of the Western Union master clock as it counts down the time remaining till the next hourly newscast, are all gone but not forgotten.
