SMPTE, DPP To Tackle IMF For Broadcast, Online

The Society of Motion Picture and Television Engineers today announced it will work with the Digital Production Partnership on a joint pilot specification project to create an IMF specification for broadcast and online.

The aim of the project is to provide a technical specification for IMF in broadcast and online applications as a breakdown of various elements, including video and audio packages composition playlists and output profile lists, SMPTE said in a press release.

Final publication of the IMF specification is expected before the 2018 NAB show in April, SMPTE said.

More information is available on the SMPTE website.

AMWA Announces New NMOS Identifiers

The Advanced Media Workflow Association (AMWA) this week announced two new identifiers for the work product of two NMOS working groups.

The identifiers are IS-05, the connection management API; and IS-06, the network control API. AMWA is encouraging the industry to use the identifiers to distinguish the ongoing work of the NMOS working groups from the existing published NMOS specification IS-04, which is the designation for discovery and registration.

NMOS, or Networked Media Open Specifications, is a family of network-related specifications AMWA makes available at no charge to vendors and end users to support product and service development.

More information on AMWA is available on its website.

AMWA has also set up an NMOS website.

Evertz, Panasonic Conduct SMPTE ST 2110 Interop Testing

Evertz today announced successful SMPTE ST 2110 interoperability testing with Panasonic.

Mo Goyal, director of product marketing at Evertz, said interoperability tests demonstrate the company’s commitment to “a smooth and glitch-free industry transition to IP-based workflows.”

The testing with Panasonic “is another example of our commitment to deliver to the industry a full IP solution based around SMPTE ST 2110.”

Apple HEVC Adoption Is A Good Sign For Next-Gen TV

Much has been said and written, including various articles by me, about ATSC 3.0 being IP-based rather than relying on transport stream as in ATSC 1 (A/53).

That is a reflection of a philosophical underpinning of the new standard that aligns next-gen television to the greatest degree possible with the rest of “digital media.” (It’s always kind of bugged me that there is a distinction made between TV and digital media, because TV was the original digital media. But that’s a discussion for a different time.)

The point is ATSC 3.0 will be able to leverage all manner of developments available to other digital media platforms that were off the table with the original DTV standard.

A case in point is HEVC or High Efficiency Video Coding. In fact, ATSC 3.0 will enable an even more powerful extension of the codec known as Scalable High Efficiency Coding. Sinclair Broadcast Group plans to leverage this extension in delivering content to mobile devices. (See: “Sinclair Free Chips Offer Key To Mobile Future.”)

The architects of ATSC 3.0 should see Apple’s announcement this week of HEVC support in macOS and iOS 11 as a strong affirmation that they are on track in aligning the next-gen TV standard with the digital media industry at large.

An article by Dan Rayburn at discusses the Apple move.

A special thanks to Mark Donnigan, VP of marketing at Beamr, for sending me a link to the Rayburn article.

JVC Cameras To Support Sports Exchange Standard

JVC Professional will upgrade most of its video production cameras models to include workflow enhancements for sports production and video coaching applications, the company announced today.

The move is centered on incorporating an interoperability standard developed by the Sport Video Interoperability Group, which the company recently joined.

Over the next six months, JVC will upgrade its GY-HM660SC ProHD sports coaching camera and GY-HM200SP sports production camera to conform to the group’s Sports Exchange Standard. The company will also upgrade the 4KCAM GY-HM170 and GY-HM200, as well as the KY-PZ100 PTZ production camera and models of the ProHD 600 and 800 Series.

Doing so will make the cameras fully compatible with applications from DV Sport and XOS Digital, the company said.

More information is available on the company’s website.

AIMS Members To Back SMPTE ST 2110 With 2017 Introductions

Nearly three in four members of the Alliance for IP Media Solutions (AIMS) are targeting the end of the year to begin offering products that are compliant with SMPTE ST 2110, the Society of Motion Pictures and Television Engineers’ professional media over IP networks standard that is in final draft form, according to a new survey of members released by AIMS today.

Seventy-two percent of members responding to the survey said they will begin shipping SMPTE ST 2100-compliant products by the end of this year, the survey found.

The survey asked about the types of ST 2110-compliant products companies planned to make available. Products are envisioned in 25 categories, including routers, line cards, video servers, switchers, encoders, audio and video processors, cameras, multiviewers, and integrated playout, the survey said.

At the upcoming IP Showcase at the 2017 NAB Show, AIMS members will participate in SMPTE ST 2110 interoperability demonstrations and show products expected to come to market in the coming year at the IP Showcase, which is part of the 2017 NAB Show.

Focus On ATSC 3.0 At 2017 NAB Show


TV broadcasters attending the 2017 NAB Show will travel to Las Vegas with two industry-transforming topics in mind: TV spectrum repack and the approaching rollout of next-gen TV based on the ATSC 3.0 standard.

Like it or not, the two are intertwined -so much so that at times it can be tough to tell where one topic begins and the other ends.

That’s especially true when it comes to the nitty-gritty of the technical decisions to be made about transmitters, antennas and other RF infrastructure for the repack.

While broadcasters are not allowed to pay for the expense of ATSC 3.0 deployment with reimbursements from the $1.75 billion broadcast relocation fund authorized by Congress, they won’t want to make a decision about moving to a new channel assignment without considering how to do so in a way that’s consistent with their business goals for next-gen TV service.

What follows is list of NAB Show and PBS TechCon sessions that address ATSC 3.0 directly, or in some cases, such as FCC Chairman Ajit Pai’s keynote, are likely to include important information relevant to next-gen TV.

Besides sessions, the NAB Show will offer special events and pavilions devoted to ATSC 3.0, which are also listed.

A special effort has been made to separate ATSC 3.0 sessions and events from those related to the repack for your convenience when planning your visit to Las Vegas. However, there may be some overlap. If your primary interest is the repack, I have segregated those sessions on a separate blog post found here.

Of course, more details about the sessions, pavilions and other ATSC 3.0 happenings are available on the NAB Show website and the PBS TechCon website.

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.
