Here are two more presentations that should convince you to head to Sin City for NAB Show this year
Once per year, the center of the broadcasting universe is in Las Vegas. You need to be there.
If you still need a little help deciding, let’s look at some additional presentations to be made at this year’s NAB 2018 Broadcast Engineering and Information Technology Conference. Last time we brought up a couple of interesting ones happening on Saturday; this time, we look at Sunday. And, keep in mind this is only a small fraction of what is going on. Take a look here to see the entire schedule.
Keyur Parikh, director of GatesAir’s Intraplex Business Unit, will present Reliability for E2X and other IP traffic across Radio Studio to Transmitter Link on Sunday, from 10:40 a.m. until noon in N260-D. The abstract reads as follows:
“While the IP based Studio to Transmitter Links (STLs) have both reduced operational cost and increased connection flexibility, they are prone to packet losses that can degrade the quality. To overcome quality problems due to packet losses, audio over IP codec vendors have come up with innovative methods such as dual-streaming, FEC etc. While these methods provided reliability for the main audio and FM MPX signals, broadcasters were still struggling to achieve reliability and security for all other network traffic across the STL, most notably, HD Radio’s Exporter to Exciter (E2X) stream. Packet losses with E2X stream can have a detrimental effect on the quality, which is causing most broadcasters to locate HD Radio equipment at the transmitter site. In this paper, we will introduce a new IP technique which leverages the current transport technology for the main audio and extends it to reliably transport any TCP/IP application packets, including E2X streams, multiplexed or non-multiplexed with the main audio signal. We will review details on how the technique protect critical application data against both packet losses and security threats and becomes a key enabler for broadcasters to locate their FM and HD processing equipment at the Studio. We will also describe different operational use cases where this technique is being used to accomplish reliability of audio, E2X and other IP traffic over public networks.”
Ken Tankel, product manager for Linear Acoustic, will be giving the presentation “Latest Updates on Audio over IP & AES67″ on Sunday, also from 10:40 to noon, but in N260.
“Audio over IP has been a revolutionary innovation, changing almost everything about how the job of professional audio gets done. The hallmark of a true revolution is that it keeps going, the change keeps evolving and growing. This paper will give an overview of the current state of the audio over IP technology, and its impact on the industry as of 2018. Coverage will include the use of AES67 as part of the latest SMPTE standards, the growth of interoperation of both industry standards and proprietary AoIP systems, the penetration into the automotive, entertainment, government, and public address wired sound systems. “
It’s too early to tell what the end result will be, we’re anxious to answer this question
OSLO — One of the advantages radio has over the years had with respect to other services like Pandora, Spotify (and other online sources) is that everyone already had one or more radios in their homes or cars.
Now, though, with the ubiquitous presence of smartphones, that advantage is gone, with the possible exception of inside the car.
So the question must be posed: Why would you force all of your listeners throw out all the radios they already have and buy a new one? How many of them will bother? That’s the operative question as we watch the results of the FM switch off in Norway. By the way — though it’s too early to tell what the end result will be, we’re anxious to answer this question and I, for one, can’t help but pour over the initial findings.
“The number of weekly listeners is almost the same as before the switch off. However, the number of daily listeners is down by 463000, according to listening figures just published for January 2018,” reports Radio.no . The Director of Digital Radio Norway, Ole Jørgen Torvmark, thinks that since there are fewer radios in Norwegian households, that there are fewer places and times to listen, thus explaining the drop.
The number of radio devices that can receive national radio stations has been reduced by almost 50% after the FM-switch off, according to the Digital Radio Survey, citing research from Kantar Media. Notably, though, according to the PPM survey (also Kantar Media) almost 3.7 million Norwegians listened weekly to radio in January 2018. That is only 44,000 less than in 2017. 2.6 million Norwegians listened to radio every day in January 2018, 463,000 fewer daily listeners compared to 2017, according to the same article.
“Our experience from the early switch off regions has shown that the listening figures drop at first, and they then start to rise again when consumers have had time to replace their FM radios,” said Torvmark, quoted in the same article.
Our correspondent in Norway doesn’t share the optimism of Mr. Torvmark. Eivind Engberg, whom we have quoted previously, thinks local FMs will be unprofitable with two–three years, and many of them will have to go dark. “It’s a really bad idea to shut down the FM system. Reason number one is clear: Every listener has access to many FM radio sets these days. So lesson number one is to not shut down the feed that can access millions of receivers and end-users,” writes Eivind. “The second reason: Don’t forget the end users. If they are not happy — then you’re out of business very soon. It’s the end-user that will decide the future distribution of radio — not the broadcasters. If the end-user loves the radio — don’t make him lose the signal so that he’s forced to find other workarounds…then the end-user might end up at Pandora or Spotify.”
