It is definitely no secret that radio broadcasting has been transferring away from its century-old analog over-the-air supply platform.
One massive media firm, the Sinclair Broadcast Group, is now field-testing a supply modality that will show to be the medium’s subsequent step into twenty first century broadcast ecosystems.
The ATSC 3.0 or “NextGen TV” IP-based digital tv transmission system is being rolled out quickly throughout the nation, with a projected availability in 82 % of US markets by yr’s finish; and the know-how is being beta-tested at a Sinclair-owned ATSC 3.0 Class A tv property within the Washington, DC market, WIAV(CD).
However for Radio World readers, the story of curiosity right here is that, along with a number of streams of NextGen TV content material, the station is offering a “multiplex” of audio providers that features Hubbard Broadcasting’s all-news operation within the nation’s capital, WTOP( FM).
Nonetheless open door?
Mark Aitken, Sinclair’s senior vp of superior know-how and president of One Media 3.0, says the initiative is an element of a bigger effort exploring the complete potential of the hybrid over-the-air/web digital tv transmission commonplace by way of new enterprise fashions and alternatives for broadcasters.
“We have been constructing out the Baltimore/Washington market with some ATSC 3 showcase functions for automotive,” mentioned Aitken. “ATSC 3 opens the door for offering extra content material past tv providers.”
The package deal of a dozen or so audio providers, together with WTOP, is offered free to homeowners of ATSC 3.0 tv receivers. That is enabled via an app that is simply executed on the units themselves as a perform of the NextGen TV interactive layer.
“With an ATSC 3 tv set, the consumer launches the app that is introduced on the channel,” mentioned Aitken. “The app lists the obtainable providers. We launched the audio providers within STIRR XT (Sinclair’s model for NextGen TV various providers).
“Once you flip to the channel there is a very recognizable icon that appears like a distant management that questions the viewer about launching the app. Utilizing the distant management the consumer can navigate round numerous providers; climate, information, visitors, headlines, and so on. As effectively, there may be STIRR XT, and within which are music providers which embrace nation, rock, classical and different providers. The WTOP audio is only one piece of this [although] it is on the high of the audio service checklist as we needed to convey native radio into the atmosphere.”
Aitken added that the “radio” app just isn’t particular to at least one make of NextGen TV however is designed to put in on any of the LG, Samsung and Sony units that supply ATSC 3.0 functionality.
The music channels accompanying WTOP are by a third-party Stingray, which gives custom-made audio providers.
Various to satellite tv for pc?
Aitken famous that this NextGen TV audio supply service is regarded as a doable various to that offered by satellite tv for pc broadcaster SiriusXM, however with the addition of current native radio providers that is already conversant in listeners.
“If we are able to embrace native radio in numerous markets as a part of that entire expertise, we consider that there is a compelling shopper proposition to supply that as a paid service. You would possibly get 100 channels which are evenly the identical and never a lot totally different than SiriusXM — for instance ’70s, ’80s, ’90s channels, an Elvis channel, a classical channel, all of these — however a part of that blend needs to be native radio .”
Aitken mentioned the inclusion of native radio programming streams and different audio with tv is sensible, particularly with the plethora of shopper units for consuming content material that exist at present.
“When content material is available in on totally different platforms … this can be a barrier to many shoppers — having to change from one platform to a different,” he mentioned.
“A part of the equation is getting the consumer interface proper. Folks do not like having to push buttons apart from ‘channel up/channel down’ and ‘quantity up/quantity down’ in between providers. NextGen TV could be the widespread platform that brings totally different providers collectively for a fantastic shopper expertise.”
Aitken envisions utilizing the improved capability for delivering knowledge that is a part of the ATSC 3.0 commonplace for supply of maybe 50 to 100 or extra audio providers, with out affecting the potential for concurrently offering very high-quality tv.
“[With ATSC 3.0] we’re doing HD video with 3 mbps sometimes, if one of many channels is working with HDR (excessive dynamic vary), we would use extra bits. Nonetheless, the bits used [for AC-4 audio] proper now are inconsequential. You might do a voice-only service utilizing xHE-AAC compression with solely 6 or 7 kbps. You are able to do stereo music providers beginning at 12 kbps. So, you are not speaking about utilizing up an entire lot of capability.
“What meaning on the inverse facet is that you may present a really sturdy tier — a really sturdy PLP (bodily layer pipe) inside ATSC 3 with a really sturdy modulation and coding formulation — and supply wonderful indoor and cell service with out having to sacrifice a whole lot of spectrum.”
(The unique ATSC 1.0 digital tv compression scheme caps knowledge charges at about 19 mbps inside a 6 MHz tv channel, whereas the rather more environment friendly ATSC 3.0 coding methodology can present upwards of 25 mbps throughout the identical 6 MHz of broadcast spectrum at comparable SNR. )
When requested about promotion of the ancillary audio service obtainable on Sinclair’s DC TV station, Aitken mentioned that there had been none.
“There’s been no advance publicity; individuals uncover it via the method of discovering ATSC 3. The response to [the audio service] has been constructive, primarily based on knowledge analytics collected on these units.”

Such knowledge analytics results in one other huge plus that is related to ATSC 3.0, whether or not the programming being consumed is video or audio. The hybrid OTA/web connectivity of the NextGen TVs gives a return channel from shoppers that may present content material producers or distributors with “instantaneous” demographics on how their content material goes over with shoppers.
“Within the ATSC world the place the sensible TV is linked to the web, we are able to get actual knowledge about shopper actions,” mentioned Aitken. “That is actual knowledge, not knowledge extrapolated via Nielsen.”
Aitken mentioned that at this level within the trial his firm just isn’t paying a whole lot of consideration to such suggestions for actionable exercise, nevertheless it might be precious because the idea of radio-via-ATSC 3.0 takes off.
He talked about that the potential interactivity between content material originators and shoppers afforded by NextGen TV is beginning to get some artistic juices flowing throughout the radio group.
“A few of the radio guys have concepts about issues that they’d love to do, however cannot do in radio at present, like promotions for concert events,” mentioned Aitken. He mentioned Sinclair has been approached by some radio teams for extra details about “3.0 radio.”
Sinclair just isn’t presently within the radio broadcasting enterprise, however has owned properties within the Seattle market prior to now, and beforehand experimented with airing radio audio there in reference to its ATSC 3.0 TV broadcasts. Requested if the corporate is contemplating re-entering radio, Aitken replied that there had been some dialogue, however nothing has been determined but. The on-going DC market “proof of idea” trial is being performed simply “to indicate that there are automotive and audio enterprise alternatives.”
“As we’re not within the radio enterprise [now]we’re in all probability partnering the place we promote the bits and another person gives the audio service.”
I’ve noticed that whereas the audio providers at the moment are offered free, this could finally change in at present’s world of “bits for bucks,” particularly when 3.0 capabilities are prolonged to vehicles.
“Within the automotive atmosphere, we expect that such providers needs to be for pay,” mentioned Aitken. “We expect that there are alternatives, or definitely worth, in offering competitors to SiriusXM, [which comes] with an interactivity that is not obtainable on some other platform.”
