Intercom Mobility, Standards Trend Over Past Year, Says Browne

Simon Browne.

When it comes to intercoms for use in television production, the ability to move from fixed positions while doing video and audio production work and the development of audio-over-IP standards are the two most important trends over the past year, says Simon Browne, director of product management at Clear-Com.

“Some of that is being solved by conventional belt pack wireless, and some of it is being addressed in a less conventional manner using smartphones,” he says.

Growing reliance on the ability to be mobile with intercom communications reflects changes in production workflow, says Browne.

“More people involved with productions are doing different things, and I think today’s intercom capabilities are enabling that kind of flow,” he says.

The other major development is growing interest among intercom users in interoperability of systems between vendors.

“I think there is a lot of interest,” he says. “You are seeing it in things like AIMS [the Alliance for IP Media Solutions], and the fact that Dante has become pretty much an established audio standard for interoperability.”

“It’s now supplanting MADI, which was the previous technology for establishing an audio link to intercom consoles,” he says.

But what about AES67? Isn’t that the audio standard enabling AoIP interoperability?

Actually, that’s one of the reasons Clear-Com jumped on the Dante bandwagon.

“Once they [Audinate, the company responsible for Dante,] committed themselves to AES67 compatibility it closed the deal for us because we are keen on AES67,” says Browne.

AES67 is “the likely glue” between Clear-Com’s products and other audio-only and audio-video devices, he adds.


IP In TV Production Is Viable, Says VRT-EBU Project Manager

The LiveIP project being conducted by Belgian public broadcaster VRT and the EBU with the cooperation of multiple vendors has demonstrated after 18 months that IP in live television production is viable, says the effort’s project manager.

Speaking Sept. 8 at the EVS press conference during IBC 2016 in Amsterdam, Karel De Bondt reported that the LiveIP project has succeeded in delivering live television produced using IP to viewers and most recently delivered for the entire summer of 2016 a children’s channel produced out of its IP production facility, which includes a studio, production control room and data center tied.

“Every day, we went fully on-air with an IP studio that reaches households and people were watching us,” he said of the children’s channel.

“To us that is the ultimate proof that IP can make real TV that people are watching at home.”

Telos Alliance, QSC Audio To Teach AES67 Seminar

Representatives from The Telos Alliance and QSC Audio will present an Infocomm University seminar at Infocomm 2016 in Las Vegas on AES67 and network interoperability, the company announced today.

The class, entitled “AES67: Achieving Interoperability Between Audio Networks” will be held Friday, June 10, 9-10 a.m. at the Las Vegas Convention Center. The class offers attendees one CTS credit.

Marty Sacks, The Telos Alliance VP of sales, support and marketing, and Rich Zwiebel, VP of systems strategy for QSC Audio will conduct the class.

AES67 is an open standard that provides a means of exchanging audio between equipment from multiple manufacturers that are AES67-compliant using standard IP-based Ethernet network technology.

Mediaproxy Joins AIMS

AIMS logo RGBMediaproxy, a MelbourneAustralia-based company specializing in broadcast compliance logging, content monitoring and transport stream analysis, has joined the Alliance for IP Media Solutions, AIMS, the alliance said today. 

Mediaproxy offers products to broadcasters, IPTV, MSOs, cable and satellite providers worldwide. Its product portfolio includes the LogServer platform, which provides 24/7 multichannel recording, live monitoring and transport stream analysis of broadcast sources and real-time data.

AIMS is working to promote adoption, standardization and development of open protocols for media over IP. It’s initial emphasis is on the Video Services Forum’s TR-03 and TR-04 protocols, SMPTE 2022-6 and AES67.

Calrec Stands For Freedom Of Choice In IP Transport

Why does IP transport have to be an either/or sort of thing? That’s what Calrec Audio has asked itself and, as a result, is taking steps to enable one video-over-IP and three audio-over-IP approaches.

Calrec will show support for multiple IP transport formats and protocols at NAB 2016.

Calrec will show support for multiple IP transport formats and protocols at NAB 2016.

“We had held back on publicly stating Calrec’s formal direction on AoIP until we had properly assessed the market and talked to our customers,” said Dave Letson, company VP of sales in a press release. “We strongly feel that it is not the role of a manufacturer to dictate which route to take, but to facilitate the broadcasters’ choices”

In keeping with that philosophy, Calrec at the 2016 NAB Show will feature support for three audio-over-IP protocols via an AES67/Ravenna interface, an AVB interface, and a modular I/O Dante card with AES67 compatibility, as well as the SMPTE 2022-6 video IP transport standard.

Calrec’s approach will enable gateway functionality, allowing audio-over-IP in one standard to be translated into another, the release said.

For instance, and AES67 signal can be sent out as SMPTE-2022, AVB, Ravenna, Dante or AES67, it said.

“Each signal also benefits from the management facilities inherent in Hydra2. This benefit is especially powerful in remote environments where multiple trucks are connected. It means that different units can operate across multiple formats in the field, and Calrec always has them covered,” said Letson in the press release.

AIMS Adds Three Members

AIMS logo RGBAIMS, the Alliance for IP Media Solutions, today announced three new members: 5280 Broadcast, AJA Video Systems and Harmonic.

The alliance is focused on promoting the adoption, standardization and development of open protocols to transport media via IP. It has placed an emphasis on the Video Services Forum’s TR-03 and TR-04 protocols, SMPTE 2022-6 and AES67.

More information is available on the AIMS website.

New Group Takes Aim At IP ‘Splinter-Operability’

AIMS LogoA new industry group has been inaugurated to head off fragmentation in IP standards development and implementation that otherwise could make it next to impossible to realize the full benefits of IP technology when compared to existing baseband video transport and processing.

The group, the Alliance for IP Media Solutions, or AIMS, was formed by broadcast and media industry suppliers including Grass Valley, Imagine Communications, Lawo and Snell Advanced Media. It is an independent trade association with the stated goal of bringing “IP solutions to market that offer complete interoperability” are “based on open standards” and “integrate seamlessly into media workflow environments,” according to a press release issued today announcing the formation.

AIMS will promote the adoption and development of open protocols for media over IP and place an initial emphasis on VSF TR-03 and TR-04, SMPTE 2022-6 and AES67, the press release said.

Priorities of the alliance include:

  • Initiatives that facilitate education about the importance of open standards and their adoption;
  • Facilitating activities that accelerate development of solutions that support these open standards; and
  • Nurturing the creation of new standards by supporting standards bodies with participation and testing in real-world environments.

AES67: Two More Ships Set A Course For Interoperability

Two weeks ago in this space, I posted “AES67: Are Two Ships Passing In The Night?,” an interview with Aidan Williams, CTO of Audinate, regarding AES67 and the ramifications of having four separate system discovery options as part of the audio-over-IP standard.

The underlying issue, according to Williams, is that having different system discovery options can lead to problems for end users of AES67-enabled equipment because they expect it to be essentially plug-and-play.

As I wrote at the time:

Understand, Williams and Audinate have settled on one of the four discovery options specified in AES67 and would like to see the whole industry do the same. Other vendors selecting other discovery options undoubtedly would like to see the industry support their selections.

Not surprisingly, I have begun to receive other points of view on the topic. Today, I present the thoughts of Andreas Hildebrand, senior product manager at digital media technology at ALC NetworXand Kevin Gross, founder of AVA Networks, on system discovery and AES67.

AES67: Are Two Ships Passing In The Night?

“Ships that pass in the night, and speak each other in passing,
Only a signal shown and a distant voice in the darkness…”
— Henry Wadsworth Longfellow, Tales of a Wayside Inn

A funny thing happened on the way to IP audio interoperability. The Audio Engineering Society committee that developed the AES67 standard for IP audio couldn’t agree on a discovery mechanism, so it included four optional methods, says Aidan Williams, CTO of Audinate, developer of the Dante networking tech used by more than 200 OEMs in products for the professional audio and broadcast markets.

Just to review, AES67 is supposed to provide a way for audio equipment with an IP connection from one manufacturer to hook up to a piece of IP-enabled audio gear from another and communicate.

At a very basic level, before that sort of IP communications can happen, each device needs to know what it’s connected to — a process known as system discovery.

In a pure sense, AES67 provides for interoperability because all a user or vendor has to know is which system discovery options manufacturers have chosen, write some custom code to translate between the different discovery options in use and voila, the devices can communicate.
