Keeping Your Broadcast IP Network Safe in the Age of IoT

Considering an Audio over IP (AoIP) network for your facility makes sense; it’s faster, cheaper, and better than previous technologies. 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.

Telos Alliance Thought Leadership on Display at NAB 2017 

For more than three decades, the Telos Alliance has led the way for the broadcast industry with an array of groundbreaking products. As an example of how this leadership continues today, Telos Alliance personnel will lead five important sessions on broadcast technology at NAB 2017 next month in Las Vegas.

TWiRT 341 - Sports and Studio Mics with Chris Wygal

How many of us broadcast engineers learned by on-the-job training? Have you had a mentor or did you learn by doing it yourself?  Chris Wygal is the engineer and ops manager for a network of stations in Virginia and shares with us his tricks for on-location sports production and broadcast studios.

Choosing a Baseline AoIP Protocol

Since the AES67 standard was ratified nearly three years ago, a paradigm shift has occurred in the broadcast indus­try with AoIP becoming the topic both around the water cooler and in facilities around the globe.

By now, you probably already know and understand AoIP's benefits: It saves money. It makes for more efficient work­flows. It reduces the amount of equip­ment you need. It eliminates massive amounts of wiring. It leverages “off the shelf” IP-based components from the larger IT industry for easy integration.

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.

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.
