Music Choice chooses Omnia A/XE
Dozens of audio streams, under complete control

Music Choice logo Music Choice, the multi-platform video and music network, delivers its music programming to millions of consumers nationwide through their televisions, online and mobile devices. Last month, they expanded their services when they launched their first Android app, currently streaming 46 channels, live! And guess what: all of the Music Choice channels are streamed with Omnia A/XE encoding and processing software.

 

A Music Choice's spokesperson notes that, after considering several streaming systems, Omnia A/XE was the clear choice. "It has integrated well with our audio playout system. The audio quality is outstanding, and comparable to what is available from our leading providers. Since it is software-based, it also turned out to be the most cost-effective solution." Omnia A/XE is a stand-alone software signal processor and MPEG encoder (MP3 and AAC). It doesn't require a dedicated PC hardware card to operate, instead using the host processor inside the computer.

 

Music Choice
Music Choice uses Omnia A/XE to process and stream more than 40 channels of audio. 
User-friendly configuration and setup also earned praise from Music Choice. Through the main control panel screen, users can access all audio processing and encoding instances, the audio meters and processing presets assigned. Users can also create additional audioprocessing or encoder instances, delete existing ones, and start or stop individual instances.

 

Music Choice also uses Omnia A/XE to insert metadata, using the UDP port. What makes their application unique is that the data is inserted using proprietary techniques so that it can be read by their mobile apps and website - but not by other players. A/XE can accept just about any metadata format, from simple, line-based messages to XML messages and anything in between. Included with the software is a set of metadata filters which can be further edited and customized by users.

 

With 46 streams, Music Choice is one of the largest users of Omnia A/XE. To insure uninterrupted service, they maintain primary, backup and test systems. Since A/XE works in the background as a Windows service, it has no visible user interface - it's configured and managed via web browser, from any computer that can connect to the A/XE host PC.

With so many streams running simultaneously, quality control is important. "We use A/XE's log files for troubleshooting issues," says the Music Choice spokesperson. "We also rely on third-party monitoring tools to check for glitches and outages." Omnia A/XE writes system messages to log files. A new log file is created for each 24 hour period. Users may retrieve log files through the web interface, or directly from the PC on the directory where they are stored, and A/XE sends an e-mail in the event of an application error. 

 

Music Choice uses many audio streaming protocols for their Web and Mobile products. Again, Omnia A/XE was a great fit, thanks to its support for ShoutCAST-compatible servers, including ShoutCAST v2, ICEcast, Adobe Flash Media server, Wowza, Live365 and Windows Media Server, delivering audio with a wide variety of codec options: MP3 (from 8kbps, 11025 Hz mono to 320kbps, 44100 Hz stereo) Low complexity AAC (AAC-LC) and high efficiency AAC (HE-AAC). 


Not everyone has so many channels of streaming audio to manage, but Omnia A/XE is so affordable it's within nearly everyone's price range. Find out all the details here.

North To Alaska with IP-Audio
Fairbanks' KQHE proves you don't have to be big to sound big

Mention Axia installs to most engineers and they'll usually conjure up images of multiple Element consoles, engines, nodes and processors all linked together with Livewire. But KQHE 92.7 in Fairbanks, Alaska is living proof that you don't need to be nearly that big to reap the benefits of IP audio with Livewire. The newest radio station in The Last Frontier is starting out with one Axia DESQ console, an Omnia ONE FM processor, Telos Z/IP ONE IP codec and an Hx1 phone system. That's it.

KQHE Studio

For Jason Sagers, VP and engineer for KQHE, and for owner Little Flower Ministries, the expected September launch of the station marks the end of an 8-year journey. The story begins with Sager's relationship with John Bisset, Telos' Director of Western Radio Sales. "John and I had been talking about audio processors for the station, and he recommended the Omnia ONE," recalls Sagers. "When I checked it out on the web site, I discovered that Telos made lots of other cool equipment. I also liked the simplicity of how it all could all be linked together with Livewire connections. It just seemed to make a lot of sense."

 

Although KQHE may be the newest and smallest station in Fairbanks, their Axia gear has garnished a lot of attention from other area broadcasters. "Contract engineers who have visited our studio have expressed a keen interest in the Axia gear. Even though we're one of the smallest operations, our technology is way ahead of most other stations in the Fairbanks market., and they feel like they need to catch up." He adds that while some have offered to help, installation has been so simple that no assistance has been necessary.

 

Sagers wears two hats. When he is not VP and Engineer at KQHE, he's a field service tech for the FAA, often traveling to remote villages to repair and maintain navigation equipment. Until he started work on KQHE, he had no broadcast and limited IT experience. "One of the things that appealed to me about Telos-Axia is that Livewire is largely a plug-and-play medium, and I've taught myself about broadcast engineering along the way." From out of the box to ready to broadcast took Sager about two months. And it wasn't finished a moment too soon.

While most of us in the lower 48 states can look forward to another one or two months of warm weather, the beginning of September means that winter is fast approaching in Fairbanks. Sagers needed to make sure all the FM antenna and other outside work was complete. As plans were being finalized for the STL, he began to have doubts. "We had line-of-sight to the transmitter, but it was marginal. I talked to our ISP, and watched a YouTube video from Telos. The Z/IP ONE IP codec began to look like a better solution than a conventional RF STL." The desire to have an end-to-end Livewire installation also led Sagers to purchase a Nautel VS2.5 to broadcast the 2 Kw, 92.7 signal. Every Nautel transmitter is Livewire-ready, right out of the box.

 

Sagers describes the level of tech support he has received from Telos as 'fantastic.' "All companies claim to have great support, but sometimes that turns out not to be the case. I was also a little concerned because of the four-hour time difference between Alaska and the East coast," he explains. "But whenever I called or e-mailed, I either got an immediate response, or someone got back to me within 20 minutes. Since all the equipment is IP-based, they are able to log into it remotely and see what is going on right away."

 

While KQHE is starting small with Axia, they don't plan to stay that way for long. The station is an affiliate of EWTN, the Global Catholic Radio Network. Sagers notes that initially most of the programming will be streaming EWTN's content, but eventual plans are to incorporate more local programming. "There are 55 parishes spread across Alaska," Sagers explains. "We want to expand our operations to include them all, even the small villages in remote locations."

 

He is also quite pleased with the growth potential of Axia and Livewire. "The simplicity of Livewire, the modularity of the equipment, and the ease with which it all goes together means that we'll be with Telos for the long haul. There's a certain wisdom that comes from choosing the proper equipment, and it's good to know that other stations are envious of us."

Tech Tip of the Month
Find Problems before the Jocks Do with SysLog Alerting
(This month we feature a guest Tech Tip! Anthony Eden works for Hope 103.2, in the beautiful city of Sydney, Australia by day and writes about his experiences with technology on his personal website by night.)

Look inside with Syslog "How do you know when something has gone wrong on your Livewire network? Do the jocks come screaming to you? You can get ahead of the curve by configuring your Telos Alliance gear to message you using a little logging and alerting protocol called "SysLog."

 

"This nifty protocol allows you to centrally log messages from a variety of equipment, and trigger alerts based on their importance. There are two components: the client and the server. The client simply sends a UDP packet to the server, and it's up to the server to actually do something with it.

 

"You get to choose what software you use. Telos has their own free SysLog Server, but I prefer the What's Up Gold FREE SysLog Server for it's more advanced event-based alerting. If you have Nagios or another network monitoring tool, you may be able to use that. Hey, you could even write your own in under 20 lines of code!

 

"Configuration is a simple matter of putting the server's IP address into the Web GUI of your equipment. This can be found in the System page of your Axia Node, the Diagnostics page of your Element Engine and the Log Setup page of a QOR engine. Most IP-enabled Telos Alliance gear supports this protocol.

 

"Once you've done this, you should start seeing log entries appear in your server software. When navigating around the Web GUI, you'll probably see some Error messages but otherwise on a healthy Livewire network you won't see too much.

 

"The next step is to setup your alerting. How you do this and what rules you use is a matter of personal preference. In the What's Up Gold server, I choose to have anything at the Critical level or above trigger an email. I find there is too much noise at the Error level so I tend to ignore this. After a while you will get a feel for the types of messages your equipment generates, and you can setup keyword filters to treat the various messages differently.

 

"Bonus Tip: You can also setup other devices such as a Cisco Switches to send SysLog alerts to that exact same server! It's a common protocol so plenty of devices support it."

Discrepancy Sheet
Love and Rockets, Cleveland-style

Corny + Rocket All of us at the Telos Alliance share with our clients a fatal attraction to broadcasting, as well as a passion for making great audio. But many of us have other hobbies and interests that might surprise you. From time to time, we'll profile members of the Telos Alliance and what they do when they're not inventing the next generation of broadcast audio gear.

 

As a kid growing up during the 80s in the Cleveland area, Cornelius Gould became fascinated with rocketry. He put together and launched Estes kit rockets, designed and built a flying scale model of the space shuttle out of cardstock and read extensively about the space program. "My earliest memories of NASA are from the Apollo-Soyuz flight in July of 1975," recalls Gould. As his knowledge and skills developed, he became interested in the problem of designing and building a remote control (RC) boost glider, a tall order with 1980s rocketry technology. One of the first challenges was determining whether 1980s state-of-the-art RC transceivers would have enough range to control the glider once it was deployed. Gould's tests with RC gear led to his developing low-power transmitters, which in turn, led to an interest and career in radio broadcasting and audio processors.

 

Fast forward twenty five years, and Omnia brand manager and developer Corny Gould takes his stepdaughter to see the launch of Space Shuttle Atlantis. "That was the point when I knew that I wanted to get back into rocketry and build the boost glider," notes Gould. A lot had changed while he was away from the hobby. Rocket engines had become more powerful, microprocessors were everywhere and RC equipment was smaller, lighter and more versatile. His dreams of flying remote control boost gliders seemed well within reach.

 

Gould found a group of like-minded geeks in the Mantua Township Missile Agency, and became vice president of the club. He also created a blog, CPGAeronautics.com, to chronicle his research and design work.

 

Gradually, the plans for creating his boost glider became clearer. Beginning with a series of smaller custom rockets, he plans to collect data about G-forces and acceleration curves under various launch conditions for use in designing the RC boost glider. Various electronic data gathering and computerized control of key recovery functions will be developed on this portion of the project for general use in exploration of model rocketry.

 

After gathering data with an Artemis booster, which has a ceiling of about 1,000 feet, he plans to step up to the Perseus booster, which can reach about 2,000 feet. The following step, the Sagitta Heavy lift booster, will require Gould to gain additional certifications from the National Association of Rocketry. It will be this booster that will lift the glider into the air. At this point, many computerized functions will need to be developed and debugged, such as computer controlled parachute deployment as well as "mockup" shuttle / booster flight tests. "This will be a busy period of testing," notes Gould, "and the results should prove to be very interesting!"

 

The final stage will be development of the Carina Shuttle, or remote controlled glider It will be mounted on the Sagitta heavy lift booster, and released at the apogee of the Sagitta booster's flight path. As the booster returns on parachute, Gould will fly the shuttle portion back to the launch site by remote control.

 

So, when will the boost glider finally take flight? That's hard to say. Gould has no hard and fast timetable. "Getting there may take a bit longer than planned, but that's OK. It's all about the journey!"
