An IP audio revolution is taking place and Tieline is at the forefront in developing cutting edge technology for radio and TV broadcasters.

With a team of 15 full-time specialist IP engineers and technologists, backed by a dedicated team of hardware and production engineers, sales and support staff, Tieline has been busy building a new portfolio of IP products to lead broadcasters well into the 21st century.

Tieline won both Radio World ‘Cool Stuff’ and Radio Magazine ‘Pick Hit’ awards for two years running at NAB 2009 and 2010 for its Bridge-IT multipoint IP audio codecs and then Report-IT for iPhone®, which continues to take the radio broadcast world by storm.

Both these products have significant enhancements on-show at NAB 2011. Bridge-IT now has numerous multipoint connection features as well as AAC and apt-X Enhanced algorithm options. Report-IT Live Enterprise Edition can be fully programmed by engineers from the studio and will also be on display for the first at NAB.

Tieline’s new Mic Adapter* for iPhone will also be on show. It lets you connect your favorite pro dynamic mic and use dual headphones with Report-IT when you go live.

Look out for the new Tieline Genie 1RU IP STL codec making waves as the most advanced new generation STL grade audio codec for studio-to-transmitter links and multipoint or multichannel audio distribution applications.

Tieline is also the first audio codec manufacturer to announce that it is IPv4 and IPv6 ready, so you can be sure that your new codec hardware is future-proofed for connection over the new IPv6 internet infrastructure that is currently being deployed with Tieline’s SmartStream Technology.

Tieline 4G Saves the Day for Cumulus during the Super Bowl

Gary Kline, Vice President of Engineering and IT for Cumulus Broadcasting has been remote broadcasting over 3G wireless networks for several years. Recently at Super Bowl 2011 in Dallas, Texas, the team at KTCK-AM (The Ticket) used a codec with ISDN for the main broadcast link and a Tieline Commander G3 wireless codec was configured for wireless 3G IP remotes.

Acting on an educated hunch, Gary said he had a feeling that the 3G wireless network might ‘max out’ during the Super Bowl coverage with all the people at the game strangling available bandwidth and choking the data available for broadcasting. As a result, the Cumulus team performed a test broadcast using a Verizon 4G LTE modem in conjunction with a CradlePoint router connected to a Tieline Commander G3 IP audio codec - to see if it was a viable wireless backup option.

The test worked flawlessly, so the team configured their Commander G3 codec with both a 3G wireless module and the 4G LTE modem in case either network was required on short notice.

Before the game an extremely important press conference with Jerry Jones, the owner of the Dallas Cowboys, was taking place deep within the Sheraton down town. The room in which it was held was a large meeting room without any windows. The wireless-enabled Commander G3 was set up to cover the press conference, but just as Gary predicted, the 3G network was so congested that it was impossible to get a reliable connection.

Luckily the Cumulus team had the 4G LTE modem connected to the codec so they simply connected over 4G and used this throughout the press conference with great success.

Another situation occurred later during the main broadcast when unexpectedly the ISDN codec used for the main program link lost its connection. Luckily the team was concurrently running a Tieline

Commander codec over IP as a standby link and they simply switched across until the ISDN path was reestablished.

The Cumulus team read the play well in relation to 3G and had sound redundancy plans in place using 4G LTE and wired IP – Gary’s foresight and Tieline’s 4G IP literally saved the day for this critical sports broadcast.


Tieline’s Neil Morrish Discusses Why New Codecs Should Now Be IPv6 Compatible…

Neil Morrish, Tieline’s R&D Manager

The internet is running out of IP addresses and as a result IPv6 is the ‘new internet’ that has been chosen as the successor to the current IPv4 version. IPv6 solves the internet address shortage by adding many billions of new addresses to the internet. IPv4 will not be going away anytime soon, but it will be overtaken and consumed by IPv6 over time.

Although they use the same physical network, they are, for all intents and purposes, different internets. For example, an IPv4 only device cannot talk to an IPv6 only device, or vice versa. In the very near future all broadcasters will have to manage connections to both IPv4 and IPv6 network infrastructure in order to maintain connectivity across networks and the internet.

Ideally new hardware you purchase should be IPv4 and IPv6 ready, just like Tieline’s new Genie shipping later this year and Bridge-IT, so you are not left out in the cold.

Report-IT Enterprise has Changed the Newscasting Game

Report-IT Enterprise Edition has changed the way broadcasters approach newsgathering by turning your iPhone into a pocket-sized portable 15kHz live IP audio codec and ultra-slim high fidelity 20kHz audio recorder.

With the award winning Report-IT Live you can:

  • Broadcast 15kHz live two-way interviews between the talent/reporter and the studio live to air.
  • Take advantage of the inbuilt 20kHz quality mic on all 3G/3GS/4 iPhones, by prerecording interviews to the phone and then FTP these 20kHz audio quality files to the studio without needing a codec.
  • Prerecord interviews, trim them offline, build a user-friendly playlist of edited clips and insert them into your live cross to the studio later.

Safe, Secure and Simple to Connect…
To use Report-IT simply download the FREE Enterprise Edition app from the iTunes App Store and use the unique login provided by the studio to automatically log in to TieServer and download all settings for connecting to specific Tieline studio codecs or FTP servers. All you need to do is open the app, enter the password and hit ‘Connect’ to go live to the studio in a snap - it doesn’t get any simpler than that!

Reporters, announcers and remote talent don’t even need to program Report-IT to use it. Studio Engineers can use an iPhone with a special Report-IT administrator login to remotely create a unique password and define specific connection settings for each user.

This process not only makes it very simple for users to connect, it also significantly enhances broadcast IP network security by never exposing IP address details of studio codecs to reporters and contributors in the field.

Bridge-IT Delivers New Opportunities in ‘The Big Land’

“The Newfoundland and Labrador regions are vast, mountainous and sparsely populated,” said Shawn Basha, Director of Engineering for Steele Communications. “This area is known as ‘The Big Land’ and traditionally a lot of our transmitters have been fed program using either satellite or Telco copper. Both of these options are very expensive to install, operate and maintain.”

“We first bought a pair of Tieline Bridge-IT IP codecs as a backup STL connection for sending IP audio from our studio in St. John’s to our transmitter site in Carbonear, Newfoundland,” said Shawn. “They performed extremely well over the regular internet so we decided to use Bridge-IT multi-unicast codecs to replace the mono satellite links from our studios in St. John’s to our three main STL transmission sites in Labrador, Newfoundland.”

“The impetus for the change came not only from a cost perspective, but also because we were performing AM to FM conversions for the stations,” said Shawn. “The sites had previously received mono audio via satellite and adding another channel would have been very costly. The reliability and cost effectiveness of the Bridge-ITs changed our way of thinking and has allowed us to place our product in communities where cost would originally have deemed this impossible.”

“The FM stations in Labrador consist of one main transmitter site and two repeaters at remote locations, where receiving repeater signals using off-air receivers was not an option,” he said. “These transmitters are located 2800km from St. John`s and 600km apart. Transmitter one is located at Labrador City, the second is at Churchill Falls and the third at Goosebay.”

“We installed regular DSL connections with static public IP addresses at the studio and each of the transmitter sites,” he said. “Using the multi-unicasting and AAC codec package at our St. John’s studio we send high quality stereo LC-AAC audio at 128Kbps to all sites and have been on air live successfully for 6 months. The satellite is now our mono back up.”

“In general Bridge-IT codecs are very simple to set up, reliable, and the automatic gain control is very transparent,” said Shawn. “When one of our sites had a bad cable pair for the DSL line we discovered that the codec link quality reading was jumping from 30 to 99 in high winds. This helped immensely to find the source of the problem and to this day I am not sure how we would have figured this out so precisely without this feature.”

“Another very useful feature is the Bridge-IT web-GUI, which is a very user friendly and easy way to program the codec,” he said. It is very convenient, especially for our remote locations. We can log in and view our connections via the internet using a web browser and check the link quality of our remote transmitter sites from a single page anytime, from anywhere!”

“You shouldn’t have to sacrifice convenience for cost and with Bridge-IT you don’t have to,” said Shawn. Overall, when you broadcast using IP you get better value for your investment dollars and more control over your connections,” he said. “Our engineers love sound of the codecs and they are very compact and cost effective.”

Report-IT ‘Codec Moments’ Score a Hole in One Every Time

Kevin Allen, “Views from the Rough”, Interviewing Allen Wronowski, President of The PGA of America with Report-IT

By Kevin Allen, Producer/Host, “Views from the Rough”

We’ve all heard of those Kodak moments and in my career as a professional photographer and now as producer and host of the weekly golf talk show “Views from the Rough”, I’ve had many of these. I’d also like to share a more recent experience, what I call my “codec moments”.

After close to 20 years in the game, and a professional sports career, I am on a first name basis with hundreds of professional athletes from every sport imaginable. The common thread – they all like golf, and they love to talk about it with me.

When interviewing hundreds of professional athletes in the past I needed my cassette recorder, mike, fresh cassettes, batteries and headphones with me at all times. More than once, something would be missing. I’d get the interview, but all the equipment was a burden and foul-ups were embarrassing. I kept thinking there had to be a better way - something simple, something compact, yet reliable.

Views from the Rough differs from other golfing shows in that it is rich in first-person interviews, and this is where my “codec moments” come in. Tieline has developed the Report-IT Live iPhone application which turns the iPhone into an audio codec and professional portable recorder. This development is huge for field reporters like me - now all I have to carry is my iPhone.

The iPhone mic has a studio quality response and I press just one button on Report-IT to connect to my studio and feed broadcast quality audio. Report-IT also lets me record and edit interviews and then play back these selections as a wrap-around within my live reports. I can also feed raw audio back to my FTP site for editing when I’m back in the studio.

For anyone who has tried to interview a celebrity at a moment’s notice, the advantages of this new technology are obvious. I can capture comments and intriguing conversations that would be missed while setting up a traditional recorder. Plus I’m not lugging ten pounds of equipment around 18 holes!

Back at the club house or the media room, I don’t have to keep an eye on equipment, and my iPhone or my iPad is ready to record those personal nuggets that make Views from the Rough so unique. I invite you to listen and judge for yourself at
