IP Audio Networking for TV... It Takes More Than a Network


WheatNet-IP is more than just an IP network that routes audio within a TV facility. It is a full system that combines a complete audio tool kit, an integrated control layer, and a distributed intelligent network that takes full advantage of IP audio.

By combining these three components seamlessly into one system, we can deliver the following:

  • A distributed network of intelligent I/O devices to gather and process audio throughout your facility
  • Control, via both hardware GPI and software logic ports, that can be extended throughout the plant as well
  • Rapid route changes via both salvos and presets to instantly change audio, mic control, and tallies between sets
  • A suite of software apps and third party devices that all communicate via the common gigabit IP interface
  • True plug 'n play scalabilty - devices are easily added to the IP network
  • Triggered crosspoints to create routable IFB throughout the facility

Just about any complication in post or live production is manageable using the highly routable features of this broadcast-proven IP audio routing and control system.

Andy Calvanese Discusses WheatNet-IP for Television

Wheatstone's VP/Technology, Andy Calvanese, discusses some of the advantages of the seamless, built-in control layer of the WheatNet-IP audio-over-IP network when used in television applications.

Tips for a Smooth IP Transition

IP Transition_2560The transition to IP may be inevitable, but suffering is optional.

You could always start with a camera with IP output and an IP audio network, two simple additions that would join both video and audio in the IP realm so you’ll never have to step into the edit room again to embed AES audio into the video.

Those cameras are available today, as are audio over IP systems like WheatNet-IP. Simple changes like this can impact workflow now, and set you up for all the benefits of a total IP infrastructure later.

The transition to IP will take time, of course. And some thought. Here are four things that your friends at Wheatstone would like you to think about:


1. Think hybrid. The ideal is a fully interoperable studio, where disparate systems and peripheral gear can talk to one another. Broadcast equipment manufacturers are working toward that goal, Wheatstone included, which is why our WheatNet-IP audio network is AES67 compatible. But until this and other interoperable standards are widely adopted, it’s important to be able to work with existing gear and systems. For many, this includes some MADI gear, some AES/EBU, some analog and some custom control interfacing to critical systems now used in the studio. For this reason, we’ve made it a priority to be able to ingest into our WheatNet-IP system virtually every audio format out there, including native analog, microphone, AES/EBU, SPDIF, IP audio, MADI and SDI.

2. Think beyond access. Think control. IP connectivity isn’t just about access. It’s about control. The more logic you can put on the network, the more control you’ll have over change. For example, WheatNet-IP has an integrated control layer that carries all the logic functions for audio. This makes a world of difference when it comes to being able to handle the unexpected or to repurpose a news set for multiple productions. Control is built into each WheatNet-IP connection point that is shared with other IP connection points across the network, giving you access to not only all sources at once, but also the presets and any associated logic that go along with each feed for controlling such things as mic ON/OFF, or changing remote mic settings for IFB, processing and other parameters.

3. Think distributed network intelligence. Centralized network management is a single-point-of-failure waiting to happen. Distributing network intelligence throughout to every IP point in the network is the smarter approach, because distributed networks like WheatNet-IP automatically build in redundancy - if one part of the network fails for any reason, the rest can keep on functioning. Each IP connection point – or BLADE – stores the entire configuration of the network onboard, which means that failover is immediate. And because WheatNet-IP BLADEs talk to each other, adding onto the network is plug-and-play for easy system expansion -- which in turn adds more control resources, audio mixing and processing tools, and more intelligence for whatever new services come along.

4. Think routable tools. Having the right tools for the job is important. That’s why we place audio tools at all IP connection points in the WheatNet-IP audio network. For example, having two stereo 8x2 utility mixers at the point of I/O makes it practical to do online mixing of sounds, segue remotely between feeds, virtually overdub and pan, you name it. Just recently, we added audio processing to our I/O BLADEs as yet another routable tool in our audio toolkit. Adding new tools is possible because each of our I/O BLADEs has a CPU with operating system inside, which we can add to, change, and make to fit just about any scenario that’s needed.

Oregon State's WheatNet-IP TV Audio System


A $3.1 million, 14,000-square-foot media center allows students at Oregon State University in Corvallis, Ore., to get hands-on experience producing content for television, FM radio, the Web, social media, newspaper and magazine.  This state-of-the-art operation could serve as a model for broadcasters looking to integrate media.

Memorial Day weekend is usually an exciting time for students wrapping up their spring semesters and heading out for summer vacation, but this year’s holiday weekend was particularly stirring for media-savvy students at Oregon State University in Corvallis, Ore.

That’s because Friday, May 22, marked the inauguration of TV production at a new 14,000-square-foot media center located on the fourth floor of the also new Student Experience Center near the university's student union.

The modern, multifaceted media center is a largely open, collaborative environment where students will get hands-on experience producing content for television, FM radio, the Web, social media, newspaper and magazines that could serve as a model for broadcasters looking to integrate media in a collegial environment.

The inaugural production, a 25-minute live preview of one of the musical groups scheduled to perform at this weekend’s Oregon State Battle of the Bands, was a test-drive before the $3.1 million facility shifts into high gear for the fall semester.

“It was an opportunity to pull the Ferrari out of the garage and take it for a spin around the block,” says Bill Gross, assistant director of the Orange Media Network, which operates all the university's media.

“We wanted our seniors to put their signature touch on the facility so they could claim they did the first live show out of the new facility.”

The new facility replaces a surplus dormitory purchased from student housing in the 1970s for media operations. “Essentially, it was a rabbit’s warren of small rooms,” says Michael Henthorne, executive director of Memorial Union and Educational Activities at the university.

“We are shifting from what traditionally has been an individualized organizational structure for each product to now being more of a single news organization with multiple means of reaching its clientele,” he says.

The facility consists of two studios and two control rooms as well as a common newsroom where student journalists working on stories for their newscast can collaborate with their colleagues working on content for KBVR-FM, the student newspaper, quarterly magazine, website and social media. The retooled KBVR-TV, which has been on a bit of a hiatus from its regular program schedule while relocating to the new digs, will begin producing a live newscast five nights a week as part of its 24/7 program lineup on a community Public, Educational and Government Access Channel provided by Comcast, says Gross.

Besides news, KBVR-TV airs public affairs, variety and music shows, educational programming and sports. The station also simulcasts online as a live Internet stream.

The facility was designed to make it easy to reconfigure and share production equipment, says Erik Utter, director of engineering and president of Erik Utter Associates, the Seattle-based video engineering and consulting firm responsible for its planning. For instance, the six Grass Valley LDX HD studio cameras — one of which is on a crane — can be moved between studios or broken down and transported for live productions from around the campus, he says.

Similarly, the three M/E busses of the Ross Video Acuity production switcher can be shared between the new facility’s two production control rooms, each of which is equipped with an Acuity control surface. Grass Valley Kaleido multiviewers also can be shared and reconfigured on the fly to display every video source in the facility as needed, Utter says.

Another example of the facility’s flexibility is the Wheatstone WheatNet audio-over-IP network. “They are completely reconfiguring their resources depending upon whether the production is a newscast, a music production or a production in concert with the FM station,” Utter says.

“They are reconfiguring that on a production-by-production basis, so the audio-over-IP was absolutely critical to having that ability.” Rounding out the lineup of news production technology in the control rooms are a Wheatstone Dimension Three audio console and Ross Video Xpression graphics and titling.

HD-SDI video is routed to the control rooms and throughout the facility via an 80-by-80 Grass Valley NVision routing switcher. Eight PTZ remote-controlled cameras provide live shots from the newsroom, rooftop, radio studios and elsewhere around the facility. Master control playout is handled by a Tightrope Media Systems server and a Ross Video MC1 master control system. Live video streams are encoded on Elemental servers.

A large, open area on the fourth floor takes the place of separate newsrooms for each medium. The common work area, dubbed “the bullpen” by students, offers a large media lab for video editing on Apple Final Cut Pro; lounge seating for spontaneous editorial meetings; and 30 Ross Video Inception newsroom computer system seats for assignment editors, reporters and producers.

Newscasts are to be run out of the control rooms under MOS control from Inception, and reporters in the field have access to the newsroom system on their laptops and mobile devices via a virtual private network, Utter says.

Inception was a good fit for the facility because it was conceived as a single software application supporting social media, online, TV, radio and print, not simply as a TV news system with Web and print modules bolted on, he says.

“It has very simplified publishing tools to publish to TV, print, Facebook, the Web or whatever.”

Inception is tied into a new Oregon State EditShare media asset management system, which is used not only by the Orange Media Network but also the athletic department and campus media services, says Gross. For KBVR-TV, the MAM provides eight channels of studio playout and recording. For ENG, students will shoot stories with eight new Sony NX-5 HD camcorders as well as with eight existing Canon EOS Rebel DSLR cameras, Gross says. Ross Video’s Inception Social Media Management will tie social media into newscasts and other programs by enabling live Facebook and Twitter polling to generate Xpression graphics.

Support for social media was a must-have requirement for the paid student managers of Orange Media Network who had a major hand in designing the new facility, Utter says.

Unlike many other university media operations, funding for the Oregon State media facility as well as the $42 million Student Experience Center comes from student activity fees. In 2010, a student referendum to fund the project passed by nearly a 3-to-1 margin, according to Henthorne.

While the annual turnover of student managers during the three-year design phase was a bit of a challenge, Utter says any drawbacks were more than offset by the fresh perspective and effort students brought to the process. That’s not surprising because not only do they have skin in the game, but many also are motivated to produce media with tools that will make them more marketable after graduation.

“Students want a place to hone their skills, to collaborate and leave the institution with state-of-the-art experience,” Henthorne says.

Trends Beyond 5.1. We Take it One Track at a Time.

RBC Headshot_BIGFor those of you who are trying to balance all the latest audio trends and having a hard time adjusting the EQ in your head, we take it one track at a time in this discussion with Roger Charlesworth, the Executive Director of DTV Audio Group.

WS: Where to start? There are so many trends that television broadcasters should be paying attention to.

RC: That’s the thing. This is a period of rapid change. We started the DTV Audio Group about six years ago, as a vehicle for network operations and engineering management to share insights on the practical application of emerging television audio technology. At the time DTV loudness was a big issue. Since then, the rate at which the technological landscape is evolving has accelerated. Stuff that we thought would take decades is happening in a matter of years. For example, it’s been fairly recent that we have had these experiences with our smart phones and tablets. You can be watching a movie in your living room and get up to go to your bedroom, and you can bring that movie with you. It’s a seamless transition. Manufacturers are working hard on all this and they got some good technology. The transition to mobile is huge, but …


WS: But?

RC: But… what’s behind that is this universal transition to streaming. Whether it is streamed to a fixed device or mobile device, it all starts to look the same. And what we’ve learned is that even the cable companies are transitioning to the stream model inside the cable plant. So linear channels are going away, and they’re able to use more efficient video codecs like MPEG-4 and they’re able to roll out new services like 4K more efficiently when they’re streamed. Everything is being streamed. That means things can move faster, change can happen faster; it’s not hardware bound.

And all of this leverages core IT technology, which is the biggest trend. That is what’s accommodated things like mobile, whether it’s streamed in your living room or to your phone.

WS: We’ve heard that this NAB could be the year of IP video switchers. What do you know?

RC: Could be, because when we look at 4K and the economics of packet switching as opposed to a traditional video switcher, it just becomes so compelling. When you get up to these higher data rates the IP switches are an order of magnitude more cost efficient than traditional SDI. I think people that play in that space are going in this direction; those companies see the value. Our member networks tell us they have already started this transition and within five years pure IP video infrastructure will be the norm for the broadcast plant.

On the audio side, IP transport is pretty easy. Radio has utilized IP audio for a long time. It’s comparable to IP telephony. That seemed exotic ten years ago and now it’s ubiquitous and leverages the same sort of standards, protocols and methodologies required for IP audio.

WS: So, where are we with regard to audio over IP in the television operation?

RC: Audio IP is happening fairly fast, as you know, but I think it’s not understood how widely important it is. If you look at the Olympics and the World Cup, we’re seeing it on the contribution side. We’re seeing large scale IP networking there and I think we’ll see it in the plant.

But the thing about IP audio that gets missed is that it’s not just a transport. It’s really about control, and that it’s an easy way to automate processes. So if you want to talk to someone in IFB across the cloud, you can do that using well-established telecommunications protocols and other proven protocols. People are just beginning to pick up on this. If you have an IP routing cloud, then communications, IFB and audio signals can all be in the same routing cloud. Instead of feeding them from one system to another, they can exist in the same environment with the audio itself.

In radio that’s pretty common, as you know. The telephone interfaces are digitally delivered and controlled around the plant digitally. But for us in television, it’s really the metadata, the management and control of processes that we should be thinking about, and then the audio routing that comes along with that.

WS: We’re probably just scratching the surface of what this will mean for live production, right?

RC: Absolutely. In sports especially, we’re seeing this trend of insourcing of production. This is where some of the production is done at the venue, but there’s also the mixing and other production done back at the central studio. So instead of having your best director in the field, he or she can just drive into work and do the Detroit game from a control room in Bristol or Stamford. The economics of that is so compelling and IP is what makes that work because you can bring a whole bunch of different kinds of signals in and mix them virtually. Because the metadata can travel in the same network, you can organically create labels and markers that this is a particular microphone, this is a camera; that metadata helps us automatically create a mix. We’re seeing a little of this in college sports, and it’s probably something you’ll see more of in the universities that have a high degree of connectivity or where the production budgets are lower.

WS: Let’s switch tracks for a minute. We’ve been hearing a lot about immersive or object audio. What’s happening with that?

RC: I think object audio is coming. It’s funny. It seemed so far off, and now we already have consumer (Dolby) Atmos available and we can buy these receivers from Best Buy and Amazon. There is a certain amount of theatrical content becoming available to consumers now and I suspect folks like Amazon, HBO, Netflix, Starz and others will start streaming a wide range of Atmos material in the near future. Still, in all, I don’t know whether immersive will drive the transition to objects as much as personalization. A big part of that personalization is accessibility and to a certain extent, there’s really a crying need for better video description and multiple language support and I think that’s where objects used in a modular approach are very useful.

WS: Where are we at with object audio?

RC: Simple, static objects are useful now. For instance, we have to have a better solution for video descriptive and an object approach is very helpful. If we can have a stream of objects in the main program and we want to have video descriptive on top of it, we can still have surround sound in the program, and have the descriptive come on top of the program and that’s really great for people that are visually impaired. Same thing for people who are hearing impaired, to be able to turn up the dialog or turn down the effects, that’s where objects have enormous value. Obviously in immersive audio, being able to fly things around and being able to render in different ways, rather than having linear channels, that’s great. But I think the real value now is in more mundane things like alternate language.

WS: Let’s talk about headphones and immersive audio.

RC: Rendering headphones and virtualized surround headphones, that’s definitely something that makes immersive audio more relevant. I don’t remember what the exact stats are, but it’s something like 70 percent of content people are listening to on mobile devices, they’re listening through headphones.

It’s a cultural phenomenon.

The gamers have had headphone surround for a while. In film post-production and sound effects editing they often employ a very sophisticated surround simulating headphone system from Smyth Research called the Realiser. They cost a fortune, but these systems are incredibly accurate and track head movement, etc. So the technology to simulate surround in headphones is pretty mature. I think we’ll see these creeping into the consumer products, and that’s what will make immersive audio more relevant. It’s not just for high-end home theaters. There’s this idea that we can probably do it in headphones, too, and we can do it in virtualized soundbars -- these surround soundbars are just starting to come out, actually, and they are mind-blowing

WS: In practical terms, what does that mean to television?

RC: For regular day-to-day television, we’re still struggling with 5.1. So the answer is we will see maybe at first just height channels added, and we’ll see that on premium sports content, for example. Even having just the height helps a little bit. It lets you take some effects off the front so you can get a little more audience or crowd reaction in or say the sound of the PA in a hockey game…and maybe in the rendering for stereo you take a little of that out. I think it’s relevant. We’ll see it ultimately because program distributors and big MVPDs like Comcast always want to offer premium content, and they’re starting to push the envelope. From a production standpoint, it’s hard to take on much more though, which is why, initially, object audio will be based on the linear, 5.1 format with some enhanced personalization or immersive elements added in.

WS: Thanks, Roger, you’ve given us a lot to think about.

Roger is the Executive Director for DTV Audio Group, but don’t let his lofty title fool you. He’s a former recording engineer and he’s done more than his share of live music production for entertainment television, including work for the David Letterman, Conan O’Brien, and Jimmy Fallon shows. He shares a passion for digital audio along with other network operators and technology managers who belong to DTV Audio Group, a trade association that spans news, sports and entertainment genres and is primarily focused on practical production issues surrounding real-time programming.

Live Production Made Easy Using IP Audio Networking with Integrated Control

WNIP Toolbox2_2000Switching between video feeds can be fairly straightforward. But switching audio feeds and creating an intercom between field reporters and the studio, not to mention setting mix-minuses – all of this can be cumbersome and time consuming. And that is where a new breed of digital mixing consoles with IP audio networking and integrated control can make all the difference.
