With NAB 2017 almost upon us, it’s a good time to reflect on how far the industry has travelled in the last few months when it comes to standards for IP in the facilities, as well as what visitors can expect from Nevion at the show.
The key role of AIMS
It’s only 16 months since 5 vendors, including Nevion, came together to found the Alliance for IP Media Solutions (AIMS) to promote open standards in the facilities. At the time, there were initially several competing proprietary standards proposed by vendors. In contrast, the standards backed by AIMS were not developed by any one vendor, and are the result of bringing together the diverse experience of many specialists in the industry. This means these standards were (and still are) not skewed or limited by the perspective of any single supplier.
By the end of 2016, all key vendors in the industry had agreed to support those standards, including the suppliers who had previously pushed their own standards (the future of which must now be in doubt).

SMPTE 2110 and NMOS
With the support of AIMS, SMPTE began work in January 2016 to develop a set of standards (documented as SMPTE 2110) specifying the carriage, synchronization, and description of separate elementary essence streams over IP (i.e. separate video, audio, and data) for the purposes of live production, based on VSF Technical Recommendations TR-03 and TR-04.
SMPTE 2110 is now becoming the de facto for essence based transport over IP.
SMPTE 2110 comprises multiple parts:
- SMPTE ST-2110-10: System Timing and Definitions
- SMPTE ST-2110-20: Uncompressed Active Video
- SMPTE ST-2110-30: PCM Digital Audio
- SMPTE ST-2110-40: Ancillary data
- SMPTE ST-2210-21: Timing Model for Uncompressed Active Video
- SMPTE ST-2210-31: AES3 Transparent Transport
- SMPTE ST-2210-50: Interoperation of ST 2022-6 streams
At the time of writing (April 2017), these parts are at different stages of definition and approval. The ST-2110-10/20/30 parts are now completed (though yet to be officially published). Good progress is also being made on ST-2110-/40/21, which once ratified, will effectively enable SMPTE 2110 to be implemented. The ratification is expected in a matter of months.
While SMPTE 2110 focuses on the transport of essences in an IP world, a separate and complementary initiative by AMWA (Advance Media Workflow Association) called NMOS (Network Media Open Specification) is defining how so-called “media nodes” (e.g. equipment) can make themselves and their capabilities known to the media network (registration), how other media nodes can find out about them (discovery).

Nevion showcases support for standards @ NAB 2017
As a champion of standards for many years, Nevion has been (and remains) actively involved in both the definition and interoperability testing of these standards.
At NAB, Nevion’s commitment will be on display. On Nevion’s booth (SU5510), products will of course be shown that are based on approved standards (SMPTE 2022-6, TR-01) and are evolving to handle 2110. Nevion will also be participating elsewhere on the show floor.
On the IP Showcase booth, aka AIMS, booth (N4824):
- Nevion will be part of the SMPTE 2110-10/20/30 interop demo
- Nevion will be showing 2110-10 with 2022-7 (“Seamless Protection Switching of SMPTE ST 2022 IP Datagrams” – know to Nevion as SIPS), for dual path protection
- Nevion will be part of the NMOS registration and discovery interop demo
- Nevion’s SVP of Engineering, Andy Rayner will be on presenting “IP Media in the LAN and WAN – what happens in between?” (Monday 24 April: 11:00-11:20am, Tuesday 25 April: 3:30-4:00pm, and Wednesday 26 April: 3:30-4:00pm)
On the Arista booth (SL13905), Nevion equipment will be involved in a SMPTE 2110 (video + PTP) demo, led by FOX Networks Engineering and Operation.
Nevion will also host an exclusive event for customers and partners on Sunday 21 April, which will feature amongst other a speaker from TV 2, who will share details of their intra- and inter-facility IP media transport project – based of standards, of course.
And finally, Nevion will be publishing the 4th edition of its popular “From Baseband to IP to Virtualization – Architecting the media production infrastructure for the future” booklet, which features detailed discussions on standards and how to architect IP networks in an essence based world. Come to Nevion’s booth (SU5510) to get your copy!
This is all very exciting, as well as a real mark of how much has happened in the industry in the last 18 months, and especially since the last NAB Show.
