How Do I Verify My NMOS Solution?
Rob Porter — Sony Europe
Gareth Sylvester-Bradly — NVIDIA
Jonathan Thorpe— Sony Europe
Watch:
Session Summary:
As the adoption of NMOS continues to increase, members of the AMWA have been busy improving and expanding the NMOS Testing Tool. This free and easy-to-use tool allows vendors, systems integrators and end users to test their NMOS solutions and ensure that they comply with the AMWA NMOS specifications such as IS-04 and IS-05. The tool can be used at any time from the initial specification of a new product or service to deployment in the field. The NMOS Testing Tool has supported Node and Registry testing for several years, but any testing of Controllers had to be carried out manually. In the last year, AMWA members collaborated to add Controller testing to the tool. This adopts a semi-automated approach with the tool instructing the Controller operator to carry out various tasks. It then automatically validates these, both by checking the messages sent out by the Controller and by confirming that the operator can see the correct information on the Controller’s interface. In this talk we will introduce the testing tool and describe these latest developments. We’ll explain how to get started with the testing tool and demonstrate some of the functionality, in particular the new Controller testing features. We will also explain how the NMOS Testing Tool has previously been used at JT-NM Tested events and how users were able to prepare themselves for future events by getting familiar with the tool at the recent AMWA workshop. The workshop additionally gave participants the opportunity to perform security scanning on their solutions with guidance from the EBU’s MCS team, on which we’ll also briefly report. We’ll finish by indicating how these tools might be developed further in the future.

The Good, the Bad, and the Ugly
Axel Kern, LAWO
Watch:
Session Summary:
Our industry has finally embraced IP. We have designed, built and implemented connected solutions of all sizes, from small flight packs to large facility projects. We have successfully leveraged many opportunities of end-to-end network systems, adding a host of benefits over the past two, remotely managed years. And we’ve all been through a lot of pain on this rocky road to discovery and registration, stream routing, status and parameter control. As an innovative industry that has faced multiple disruptions in technology over the past few decades, and has successfully adapted, we are in an excellent position to channel our experiences, learn from them, and turn them into actionable approaches. With NMOS, we launched a whole bundle of specifications to keep a clear line of sight amidst the storm of technical change, and to keep pace with innovation. This has not only brought us a lot of attention, but also recognition for forging a community out of a motley crew of competitors and customers pursuing the higher goal of mitigating rising incompatibilities in heterogeneous production systems. Today, after more than five years of intensive groundwork, extensive tests and unprecedented cooperation, we approach every new project with a well-stocked quiver of arrows. Yet, we repeatedly have to ask ourselves why some of them did not hit home and others did not fly at all. The paper presents an interim conclusion as to why a good idea doesn’t always eliminate all the bad things from the broadcast world, and why we will have to live with ugly solutions for some time to come, because they simply work.

Managing Mono Audio in an ST 2110 / NMOS Environment
John Mailhot, Imagine Communications
Watch:
Session Summary:
ST 2110 describes a system with video and audio streams, and in most systems the audio streams contain a multiplex of channels – 2, 4, 8, or even 16 channels per stream. In television production environments, there is often the requirement to route or manage audio at the mono-track granularity. By leveraging AMWA NMOS and the IS-08 audio channel mapping extension, a control system can implement a mono-track granularity of control even when using multi-channel streams. This talk describes the standards-based methodologies for doing this often-required task.
AES67 Beyond the LAN
Nicolas Sturmel, Merging Technologies
Watch:
Session Summary:
The pandemic accelerated the already ongoing trend of remote broadcasting, this led to more and more AES67 users experimenting with Wide Area Networks (WANs) despite AES67 being originally designed for Local Area Networks (LAN). The AES SC-02-12M working group on AES67 development saw here a need of describing what to expect on WANs and issued the AES-R20-2021 report in September 2021 on best practices of using AES67 outside of the typical LAN use case. We will present typical problems that arise when doing transmissions over long distance and leased networks and how to solve them while keeping interoperability with ST2210 and AES67. Be it over the internet, over a privately owned WAN, or in a data center, some constrained and limitations are to be taken into consideration: How to keep multiple sites PTP synchronous? How to prevent the issues of an unavoidable packet loss? Multicast or unicast? How to handle Quality Of Service? While most of those solutions are use case dependant, they often need a compromise. We will explain the origin of those problems and propose solutions that allow streaming of AES67 beyond the LAN.

1. A Review of ST2110 Architectures - Looking Back From the Field; and 2. Maximizing Scale and Performance With Network Orchestration
Ryan Morris & Sakti Arunachalam, Arista Networks
Watch:
Session Summary:
Part 1 – A Review of ST2110 Architectures – Looking Back From the Field
Deployed architectures for ST2110 live production have evolved and matured since the initial Monolithic installations. Leaf and Spine provides flexibility and a closer alignment to “Cloud Architecture”. This review of architectural deployments will dig into the lessons we should draw from these deployments, with regard to flexibility, initial and ongoing costs, ease of use and expansion, and provide some pointers to current and potential future direction.
Part 2 – Maximizing Scale and Performance With Network Orchestration
Dynamic Multicast works well in smaller installations, but when scale and all-out performance are needed, SDN, or Network Orchestration for ST2110 flows is essential. Orchestration allows a system to be maximally efficient in bandwidth terms, while also providing much-improved performance and scale over dynamic IGMP/PIM systems.
Practicalities and Analysis of Using PTP Over 5G Systems With Dedicated Time Synchronization Support for Media Production
Ievgen Kostiukevych, European Broadcast Union (EB)
Watch:
Session Summary:
5G systems are becoming more and more ambiguous and widespread, making them a suitable choice for remote production and wireless mobile studios scenarios, extending the local OB Van facilities, and replacing the traditional RF cameras. However, the nature of the 5G systems can often make them tricky to use for high-performance media over IP due to inherited jitter and path asymmetries. In such cases, the synchronization between media sources can be challenging. The presentation explores the possibility of using IEEE 1588, Precision Time Protocol for such applications. With 3GPP Release 16, the 5G System specifications include a dedicated time synchronization enabler tailored for IEEE 1588. It describes lab sessions performed by the 5G RECORDS consortium members testing the performance of the PTP over 5G with and without the dedicated time synchronization support. The presentation also describes the open-sourced testing setup used by the team and the methodology developed. The presentation will draw conclusions on the performance and the synchronization quality when using PTP over various 5G systems, analyze the results from the lab trials and explore possible practical applications.
Interoperable JPEG-XS with ST 2110 and NMOS
John Mailhot, Imagine Communications
Watch:
Session Summary:
JPEG-XS is the latest contribution codec from ITU, offering production contribution performance at around 3 BPP (bits per pixel) and a range of operating points above and below for different applications. In order to gain widespread adoption, it is critical to have a common mapping into IP-based transport, and a common management API. The Video Services Forum (VSF) recently published TR-08, describing in detail how to combine JPEG-XS using RFC 9132 into SMPTE ST2110-22, and AMWA is finishing the development of BCP-006-01 describing how to use NMOS for JPEG-XS streams. By combining JPEG-XS over IP using SMPTE ST 2110-22 and using AMWA NMOS, interoperable solutions can be deployed.
