An Open Platform for Media Over IP Network Load Testing With Off-the-Shelf Hardware
Acceptance testing of the new media over IP networks is a critical part of any newly built broadcast center that should not be overlooked. However, many broadcasters and system integrators often skip this step and rely on the manufacturer's performance claims. SMPTE ST 2110-21 imposes strict timing and jitter requirements that depend on predictable network behavior that must be tested and verified before commissioning the facility. Inadequate network traffic behavior due to load may impair the performance of the traffic shape, network timing, and endpoints synchronization, as well as introduce unexpected behavior in media flows traversing the network forwarding. Often this step is skipped due to cost and/or the unavailability of equipment that can generate adequate network traffic load and proper traffic profiles. The presentation proposes a solution for media over IP network load testing with the possibility of using specific media traffic profiles using off-the-shelf hardware and open-source software.
Andy Rayner, Nevion
This presentation will form a tutorial on how timing is defined currently in ST 2110 and how it is evolving to provide a more wholistic system-wide end-to-end capability. It will also look at the impact on non-linear computer-based media processing and how this timing can reconciled into ST 2110 workflows.
Open Platform for Media over IP Networks

Chris Lapp, Cisco
Multicast Routing can at times be difficult, between configuring RPs, MSDP Sessions, SSM flows, ASM flows. Why is it still so difficult?
In this Paper we will review current multicast routing technologies, Which includes PIM Dense Mode, PIM Sparse Mode, and PIM SSM. We will then jump into a new technology that plug and play for all types of multicast.
Ground-to-Cloud Media Transport Integration - Standards and Approaches
Kieran Kunhya, Open Broadcast Systems
John Mailhot, Imagine Communications
The integration of live signals into cloud-based production and playout applications across vendors brings unique challenges - the multitude of possible codecs, how to signal and find the endpoints, and making the transport robust against troubles. Within cloud-based workflows the fun really starts - how to send media signals between elements of a large-scale workflow such that the timing of the whole chain is managed - without replicating the traditional "frame-lock-step" approach we use on the ground. This session talks about the current work within the VSF to establish a flexible timing model and set of recommended practices for ground-to-cloud-to-cloud-to-ground workflows.
Jed Deame, Nextera Video
"SMPTE ST2110 has emerged as a key technology enabling flexible and scalable Video over IP infrastructures to deployed. NMOS is the control layer that makes it plug and play. The latest advancements in NMOS take it to a new level, surpassing the level of control provided in SDI while also adding a layer of security that has been sorely needed in control systems for quite some time.
It also addresses the needs of the system integrator and studio builder, enabling automatic discovery of important services required to configure endpoints automatically on startup.
More recently, features have been added to ensure stream compatibility, address compressed video of multiple types, and the most radical advancement, extending to device configuration and control.
This paper will dive into the details about what NMOS is, how it works, and then look at where it is going and how it adds significant value to the system designer and integrator."
Monitoring Live Video Delivery in the Era of Cloud and Internet, Why Video Delivery Intelligence is Important?
Adi Rozenberg, AlvaLinks
Live video production workflows have changed in the recent years as the industry is turning more and more to Internet and cloud work flows. One overlooked step that has critical impact on the outcome is the link evaluation (also called as Speedtest).
No matter if you plan to use plain Unicast, WebRTC, RTMP, RIST, SRT, NDI, JpegXs or ST2110 - you have to evaluate your link performance to the destination.
In this presentation we will explore the short coming of traditional tools like : Speedtest, Traceroute, MTR and Iperf. While those are great tools developed over the years for day by day usage by the IT teams - they are not touching base on the video problems.
The presentation will highlight a Video delivery testing approach, how it should be conducted and describe some testing parameters and their impact on the video delivery."
NMOS- Open Discussion with Jed Deame (Nextera Video)
David Grindle, SMPTE
We will present the latest news in the SMPTE ST 2110 standards suite and the developments therein, and talk about the future standardizations, focusing on the importance of widening the IP ecosystems in the M&E industry, how SMPTE can help, enabling workflows in the cloud and remotely, responsiveness to the market needs today (Rapid Industry Solutions), security and compliance of systems and devices.

QC, Monitoring and Maintenance in IP-Based Environments - We've Learnt a lot From SDI That's Still Applicable in IP Operations
Kevin Salvidge, Leader Europe Limited
"If you have made the transition from SDI to IP, you will already be enjoying the operational benefits and flexibility that IP brings. You can now handle multiple video and audio services bi-directionally over a single fibre. You can also expand your system without the eye-watering capital costs inherent in SDI expansion.
However, like any technology migration, the transition to IP has highlighted several legacy operations that we have been taking for granted in SDI. It is only when you start to use your IP systems in full that you realise some areas of IP operation behave differently from their SDI equivalent. Before we explore these areas, keep in mind that the objective of your new IP-based facility remains the same as the old SDI one: to deliver high-quality content to your customers.
Over the past 30 years, SDI equipment manufacturers have developed some highly refined operating practices that IP implementations may not have fully equalled. Hindsight would be a wonderful thing with your IP deployment.
At Leader & PHABRIX, we are extremely fortunate to have been selected as the IP Test and Measurement solution for many IP projects/. As a test and measurement equipment manufacturer, we are in effect the referees in broadcast facilities, accurately reporting and recording the in-depth impact that broadcast products have on the IP and SDI streams.
In this presentation, we are pleased to be able to share knowledge based on years of experience. This includes:
• Managing and keeping synchronised IP and SDI facilities.
• Analysing and monitoring PTP and Blackburst reference.
• Analysing and monitoring both IP and SDI video sources.
•. Analysing SDI VPID in an IP world
• Vision engineering camera switching.
• IP latency
Although you have started your IP migration, you will still have legacy SDI-based equipment to monitor in parallel with your new IP operations. Having ‘True Hybrid’ reference generators and test and measurement tools that can display simultaneous SDI and IP measurements will ensure your facility seamlessly performs whilst you initiate your IP deployment."
What you didn't know SMPTE could do for you
Let SMPTE know what you want from your membership in an open discussion with leadership.
Nemanja Kamenica, Cisco
World of IP networks allow much of flexibility, and opportunity than SDI. How can you leverage those so you can have live remote production at different location from a master control room.
Consider connecting multiple sites, geographically distant but flexible to be controlled from one master control room or import media signals so they can be processed in single location.
For user that want to move post production to the public cloud, users can leverage IP network flexibility and features, by converting transport signal to unicast, and transport over public internet.

Discussion of the relationship between the AIMS-promoting standards and the ARIB standards in Japan
Adam Salkin, Diversified
Two 2110 Systems - for IBC (International Broadcast Center) and Production Studio. Using EVS Cerebrum orchestration and Arista 7508 switches. Each system has 20 racks, split into 4 pallets of 5 racks each. Each pallet weighs between 5,000 to 6,000 lbs and uses custom racks that fold in the middle. This allows the system to travel in aircraft cargo holds. The system can be rapidly deployed - after flying across the world, an empty room can become a working CER in about 5 hours.
This presentation will discuss how this was done, the engineering trade-offs and lessons learned."

JT-NM Tested, what is it and why should you care?
Discussion with Ievgen Kostiukevych (EBU)
Chris Lennon, Ross Video
Interoperability is at the heart of everything we do. When it works well, we don't even notice it. But watch out when it doesn't!
With today's hybrid environments, stitching together cloud and on-prem, monoliths and microservices, and everything in-between, interoperability is not a given. Also, setting up and maintaining operations in such an environment is no longer practical to be done manually. Automation in the area of onboarding and orchestrating new products and services is no longer a luxury‚ it's absolutely necessary.
Catena is an open-standards approach to making all of these disparate pieces work seamlessly together, despite their existence on different platforms. It's designed for today's multi-vendor reality. It provides a simple way to orchestrate all of this, and keep it running, even when things change constantly. We'll look at what Catena is, how it's being developed within the Open Services Alliance (OSA) and SMPTE, its embrace of open source for its SDK, and the excitement in the industry for a standardized solution to the ubiquitous challenge of interoperability among media systems.
Growth of NMOS and Why We More Than Ever Need an Open Control Plane
Felix Poulin, CBC/Radio Canada
"In this presentation, we will review the roadmap of Network Media Open Specification (NMOS), covering the latest publications and the work in progress. And we will show that NMOS has reached a level of wide adoption and has the momentum to become the primary Open, Interoperable and Secure control plane we need.
NMOS being format agnostic since day one, the Advanced Media Workflow Association (AMWA) now provides guidance for using JPEG-XS with NMOS (BCP-006-01) and is working on further support for compressed format transports such as NDI, H.264/H.265 and MPEG Transport Stream. We are also actively working on improving the plug and play with NMOS Stream Compatibility Management (IS-11 ), and improved usability with added Distinguishing Information for NMOS Node and Device Resources (BCP-002-02). Last but not least, a long awaited work on IS-12 NMOS Control Protocol will bring NMOS into the layer of operational control.
The NMOS community is more dynamic than ever, showing the traction of a large segment of our industry who choose to work together on common methods rather than spending more effort into their own secret sauce that ends up restricting the choice of the users to a subset of supported products. At the last Joint Taskforce on Networked Media (JT-NM) Tested event in August 2022, 74 devices (+110% from 2020 event) from 35 vendors (+75% from 2020) and 87% of all ST 2110 devices were supporting NMOS. At the recent AMWA Incubator Workshop in March 2023, 25 organizations showed up to prototype implementations of the developing specs. Moreover, the community work methodology has evolved following agile principles which improved time to market and maturity of specifications.
With fast growing complexity of live media systems into software and IT era, and the need for more dynamic facility from sharing of resources on-premise and extending with cloud elasticity, the need for our industry to invest our efforts on functionality and workflows rather than spending on interoperability issues is expressed as a strong traction of NMOS as an Open, Interoperable and Secure control plane.
Felix Poulin is the user-chair of the NMOS Steering committee.
Next-Generation Television Broadcasting in the Amazon Rainforest With ST 2110

Bruno Parreiras
We recently completed a project for a television system that utilized the ST-2110 standard to provide high image and sound quality for up to 18 open TV channels. This system utilized virtual machines on Cisco HX servers to manage and operate the channels. Of these channels, 16 were affiliated with Globo and 2 with Amazon Sat, providing a diverse range of content for viewers.
This system was managed by Nevion's IPath, which allowed for the conversion of 128 input SDI signals and 128 output SDI signals to the ST-2110 standard. To ensure stability and reliability, we utilized a Spine-Leaf network, with Cisco 93240 switches serving as the Spine and 9336 switches serving as the Leaf. This network architecture was designed to handle high traffic and provide consistent performance.
The system also included R&S Prismon multiviewers, which allowed for efficient monitoring and control of multiple channels. This was especially important as the system was designed to accommodate up to 10 workstations, each capable of operating up to 4 channels simultaneously. These workstations were equipped with user-friendly interfaces to ensure easy operation and control of the system.
In conclusion, this television system project was designed to meet the needs of the broadcaster and its viewers. It utilized the latest technology and network architecture to provide high image and sound quality for up to 18 open TV channels. The use of Nevion's IPath, Spine-Leaf network, and R&S Prismon multiviewers ensured efficient operation and reliable performance. We believe that this project will be a valuable addition to the television broadcasting industry and we look forward to its continued success.
Benefits of Using SMPTE ST2110 and PTP in Virtual Production
Thomas True, NVIDIA Corp.
Virtual production stages combine state-of-the-art LED displays with high-resolution computer generated content rendered on a complex cluster of synchronized render nodes to achieve the illusion of reality. The integration of ST2110-20 video essence streams synchronized with the IEEE 1588 Precision Time Protocol (PTP) is bringing benefits in two primary areas, a significant latency reduction in the communication of the camera view frustums between render nodes and a simplification in deployment removing the complexities of traditional SDI/HDMI and Display Port
creating a complete network-based environment built upon Common-Off-The-Shelf (COTS) hardware. This presentation will provide a technical overview of the integration of these technologies in virtual production workflows and the benefits achieved using the integration into Unreal Engine as an example.
Minimizing the motion-to-photon latency between camera movement and the resulting display of content is extremely important to maintain the illusion of reality. At the same time, the content that the camera captures must be extremely high resolution such that it is indisquishable from reality. Unfortunately, generating all the content display within the virtual production volume at such a high
resolution at all times would require an excessive amount of computing resources. As a result, only the content within the in-camera view frustum is rendered at high resolution as the camera is moved around the displays. To achieve this, the coordinates of the view frustum must be computed and communicated between the render nodes. Traditionally, each render node has recomputed the in-camera view frustum. Using PTP synchronized multicast ST2110 100Gbps essence streams the view frustum can be recomputed and multicast to each render node with sub-frame latency. In addition, the in-camera view frustum can also be larger resolution, so instead of 1 GPU generating 4K you could feasibly have 4 GPUs generating a combined 8K for high quality.
When PTP-synchronized ST2110-20 video essence streams are used to drive the video display wall controller rather than traditional SDI/HDMI or DisplayPort latency is further reduced. Traditional display technologies require a complete frame to be rendered and placed in a frame buffer prior to scan out while packet-based networking permit render frames to be communicated to the display
controller as groups of lines at sub-frame latency. The length restriction complexities of HDMI and DisplayPort cabling are also removed IP video essence streams are utilized.
PTP-synchronized ST2110-20 capture and playout video essence streams have now been integrated into Unreal Engine 5.1. Users can now configure and use ST2110-20 input video essence streams from cameras or other environments directly in the virtual production environment. Meanwhile, final composited video output to the LED wall controller is transmitted as multiple PTP-synchronized
video essence streams.

Discussion with Carlos Eduardo Lopes (Rede Amazonica)
"Your Flight Will Be Delayed by 5 ms" - Understanding Latency in AoIP Systems
Andreas Hildebrand, ALC NetworX
The presentation sets the scene by explaining the fundamental differences between circuit-switched packet-switched networks (in principal, the difference between traditional analog / digital and network-based transport mechanisms). While circuit-switched networks in principal are only affected by the speed of light and thus latency is a direct result of distance, packet-switched networks add a number of additional factors to the calculation. Even more complex, most of these additional factors are highly dynamical, depend on other factors or can be configured to match particular applications or use cases. The presentation looks at important factors like network technology and topology, stream and packet configuration, device implementation and many more aspects. It also describes the highly dynamic effect of other network traffic with respect to latency.
While all of these factors appear to implicit that IP-based media transport technologies are not applicable to use cases with low latency requirements, attendees will learn how to counter all these variable factors, what latencies are actually achievable and what benefits are offered by flexibility IP-based systems are offering.
Kent Terry, Dolby Laboratories
Work has been progressing in SMPTE and other standards bodies to define standards that will fully enable all features of Next Generation Audio codecs, such as Dolby AC-4 and MPEG-H, in ST 2110 networks. Standards are in place to support many current applications, but upcoming standards will enable new capabilities that can fully exploit all NGA capabilities, as well as future advanced audio applications. The SMPTE ST 2110-41 Fast Metadata standard currently is one key standard that will enable these functions. This session will cover recent work on ST 2110-41 and related standards for carrying rich audio metadata, including Serial ADM (ITU-R BS.2095) metadata. Recent work on file format standards that will enable seamless interchange of ST 2110 audio and metadata with file based workflows will also be discussed.
Discussion of RIST Control
The RIST Activity Group in the Video Services Forum is currently working on subjects related to control and management of RIST systems. This work can also possibly be extended to manage other streaming protocols. The plan is to eventually release this as one of the TR-06-4 Parts. The objective of this meetup is to solicit technical input, requirements, and feedback on where this work should go. It is intended to be an open discussion with all interested parties.
Andy Rayner, Nevion
This presentation will explore the use of video compression in IP production and will look at the drivers and considerations, including commercial viability of required connectivity, meeting latency requirements, meeting quality requirements etc.
It will cover the standardisation of the compression integration into ST2110 IP production in both the data plane and control plane as well as in other proprietary approaches.
It will give examples of compression deployments and also look and how it might be used in future. It will also address the concerns of compression concatenation

Do We Really Need PTP? A Comparison of Clocking & Synchronization in RTP, RAVENNA/AES67 & ST2110, AVB and IPMX
Andreas Hildebrand, ALC NetworX
The presentation starts by introducing the differences between asynchronous, plesiochronous, isochronous and fully synchronous operations. It then looks at particular synchronization requirements of professional media transport systems.
After setting the scene, the individual synchronization methods provided by various common transport technologies are explained and compared against the requirements. The presentation looks at the inherent asynchronous operation of RTP as specified in RFC 3550. It then explains why RAVENNA, AES67 & SMPTE ST 2110 required a more advanced synchronization method, why PTP had been chosen and how synchronization is actually achieved.
Another popular transport mechanism for certain fields of application is AVB; it turns out that AVB also utilizes a variant of PTP but differs from the before mentioned standards in the way it actually implements synchronization.
Finally, the presentation looks on how IPMX implements synchronization, in particular as it claims to be SMPTE ST 2110-compliant but can also work without PTP. In the conclusion, the benefits and drawbacks of each method are highlighted and the question if we really need PTP will be answered (or not?).
Tools for Managing Deployments - Ground or Cloud or Both
John Mailhot, Imagine Communications
Ansible, Terraform, CI/CD, we all hear these terms - but what do these tools really do, and could I use them for deploying and managing television infrastructure? This presentation will cover a new-user level of detail about these popular Infrastructure-As-Code tools, and how they might be applied to the unique challenges of managing television infrastructure.
Do we really need PTP?

VSF TR-10, The IPMX Open Specifications Detailed Review
Jean Lapierre, Matrox
In this presentation we will review the VSF TR-10 suite of specifications. IPMX is based on the SMPTE ST 2110 standard and as such the VSF TR-10 suite of technical recommendations is a set of differences between SMPTE ST 2110 and IPMX.
It has been more than a year since a detailed presentation on the IPMX specification was done. A few things have changed, and the transport protocol part of the specification has been published.
We will go over the TR-10 transport and timing specifications an explain the main differences between IPMX and SMPTE ST-2110. We will cover the mechanism that enables IPMX to offer low latency transport of AV signals over an IP network. We will spend time discussing details of VSF TR-10-1, the System Timing specification. TR-10-1 contains the main aspects of IPMX that are different from SMPTE ST 2110. We will also cover the transport of audio and video using uncompressed and compressed essences.
Finally, we will review the role of the AMWA NMOS suite of specifications in a IPMX network.
Samuel Recine, Matrox
This presentation will review how the links between ST 2110 and IPMX combined with the ingredients in IPMX offer valuable utility to end users, developers, and integrators.
We will investigate how IPMX is designed to allow IPMX equipment to work in ST 2110 networks with PTP, in AV/IT asynchronous networks with asynchronous sources, and in modes of operation that leverage PTP differently and advantageously.
We will investigate which types of equipment are already implementing IPMX and reasons for its growing popularity.
We will discuss the latent demand for a robust IPMX road map.
We will discuss the place of IPMX amidst a field of other media over IP approaches.
Andy Rayner, Nevion

IPMX - All your questions answered
Discussion with Andrew Starks (Macnica)
Paul Atwell, Media Transport Solutions
A common theme of all NAB presentations is how advancements in technology can be applied to lower costs. Underneath all the IP applications are the IP connections necessary for transport and workflow. This presentation will explain to both newcomers and experienced IP veterans how low-cost IP connections can be provisioned and deployed for reliable, high-bandwidth connectivity when combined with new resources available through RIST, SMPTE2022-7, and other TCP & UDP packet protecting tools.
The presentation will include real-world price comparisons demonstrating how lower Total Cost of Ownership, lower Monthly Operating Cost, and high Service Level expectations can be achieved with low-cost connectivity and compared to higher-priced, facilities-based, contracted connectivity with high SLAs.
A real-world application from actual multi-ISP connected delivery will be displayed in the final example, comparing the total cost of multiple, low-cost connections with high service availability to traditional high-bandwidth, high-cost Ethernet/IP WAN/Internet connectivity.
Discussion about audio capabilities and requirements for IPMX
Discussion about audio capabilities and requirements for IPMX
Chris Lapp, Cisco
Kubernetes is an ideal platform for deploying web applications, but lacks some features needed to support real-time media applications. For example media production requires minimal loss and jitter when forwarding multi-gigabit media streams between different stages of the media ingest pipeline. Likewise edge video deployments often require each camera feed to be replicated to multiple real-time machine learning applications. In this presentation, we will look at current technologies that exist inside of K8s and how they lack support for Real Time Media. We will then look at a potential solution to this problem with Media Streaming Mesh. Media Streaming Mesh is an open-source project that addresses these use cases in a cloud-native fashion by deploying real-time media proxies to each Kubernetes node, with a per-cluster control plane ensuring that camera feeds, real-time micro-services, and external viewers are meshed together through the proxies. In this presentation Chris will give an overview of Media Streaming Mesh and how it can be used to distribute a video feed to multiple downstream applications in a Kubernetes cluster.
First Step in Media-over-IP Network Design: What Should We Do?
Koji Oyama, Xcelux Design
One of the current biggest issues in the design and development of the SMPTE ST-2110-based broadcasting facilities is the shortage of Media-over-IP (MoIP) network design engineers who understand both broadcasting and network communications. This is the topic that has been discussed for several years, and I have been working to train engineers over the past years through my experience of the MoIP network design, the situation is getting worse and more serious as the number of the facility developments increases.
This presentation can help the target audience, broadcast engineers, who are studying or to study MoIP network technology. When trying to build an actual ST-2110-based network, the first question would be how we design a specific IP network. Unlike peer-to-peer SDI network where we can focus on the physical connection, the data on the MoIP network can be transmitted with inbounded multiple streams in an Ethernet optical cables, and multicast routing settings are required in its network switches. In other words, not only physical design but also logical design becomes more important. The more complicated the system becomes, the more complicated the logical configuration becomes. The network architecture design and its IP addressing could be a key to success of the reliable and scalable network. These technique and idea would be similar as the ones in software engineering, which kind of knowledge and skill set has never been needed by broadcast engineers before.
If the SDN controller manages the configuration of its network switches in the near future, it may be possible to build a system without knowing specifically how to implement the logic network design. However, once the network occurs in trouble, engineers who don’t have the network design skill would be at a loss, there should be a risk that we would not be able to analyze to take workarounds. For this reason, I believe it is necessary to study the fundamental skill of such appropriate MoIP network design.
At the previous NAB2022 and IBC2022 IPShowcase, I introduced the essential terminologies for configuring network switches that network engineers should know (VLAN, VRF, Multicast routing, IGMP, PIM, OSPF, LAG/LACP etc.), and how to design and verify the logical network. In addition, I shared some information about the actual issues I have faced so far.
In this presentation, after summarizing the previous two talks, I will focus on the 'design' that engineers should think a little bit more serious, such as network architecture, network switch selection, physical connection design, and logical connection design including IP address assignment. I would also like to explain some more tips on how to do the design. In addition, I would like to talk about things to be careful about in the design, and things to think about in the future, such as safety design to prevent unexpected failures and errors.
Ciro Noronha, Cobalt Digital
In November 2022 the Video Services Forum (VSF) published TR-06-4 Part 1, Reliable Internet Stream Transport (RIST) Source Adaptation. The purpose of RIST is to provide a common industry specification for low-latency, reliable video contribution over the Internet, so that broadcasters are not locked into proprietary solutions. Source Adaptation adds the ability for the content sender to dynamically adapt to network conditions. In its simplest form, a live encoder can change its bit rate based on the instantaneous available bandwidth. In a multi-link situation, the sender can also dynamically change the way the content is split between the links. Such techniques are not new and have been in use for years, especially for cell bonding solutions. However, these are all proprietary systems. VSF TR-06-4 Part 1 opens it for multi-vendor interoperability, while allowing individual implementers to innovate. This presentation includes a technical description of TR-06-4 Part 1, as well as preliminary field data from tests performed over the Internet. The tests indicate that the Specification works well in practice and is a viable open alternative for proprietary systems. Moreover, since RIST is based on RTP, it ensures backward interoperability with existing systems.
IP Works, Until it Doesn't. Maintaining SMPTE ST 2110/NMOS Installations in Practice
Stefan Ledergerber, Simplexity GmbH
Oliver Ettlin
SMPTE ST 2110 and NMOS installations are becoming more common these days and seem to work well. However, due to the complexity of setting up such systems, they largely become static installations, losing some of the greatest advantages of IP networks, like being inherently flexible. However, practical experience shows that detailed, stream-based monitoring is often lacking. If the system is to be flexible, a good option would be that end devices actively report back if one of their configured streams has errors. Based on experience, this presentation highlights some typical problems in operating an IP-based audio/video-over-IP system and suggests a number of parameters that should be monitored in real-world situations. It also illustrates that a possible standalone monitoring solution must be closely synchronized with the control system, since the streams naturally change constantly. The authors searched for a minimal set of alarms that are helpful to make the majority of practical problems obvious. They come up with a short list of specific alarms that should ideally be implemented in every audio/video-over-IP device - and possibly find their way into standards such as NMOS.
A concluding section illustrates how these few alarms, if reported on an interface-basis, can identify the typical practical problems observed in audio/video IP networks today.

Sync, Time, and Timestamps – using the new tools in SMPTE ST2110
How to manage the timing of signals within a SMPTE 2110 environment? this meet-up is hosted by some of the 2110 participants to address questions and comments about the ST 2110 timestamping model.
How Can the Delivery of IP Broadcast Workflows be Simplified With the Adoption of IS-12 Control Protocol
Nikolaos Katsampekis, Pebble
This presentation introduces the IS-12 Control Protocol (work in progress), one of the latest NMOS specifications provided by AMWA.
We will outline an end-to-end scenario typically found in a ST 2110 compliant IP Broadcast facility and touch on the key roles that an NMOS Broadcast Controller/Orchestrator tool plays in that facility and that workflow. E.g., from signal acquisition to signal monitoring, including parameters adjustment and finally leading to the desired edited material ready for distribution.
As part of the workflow exploration, we will highlight some of the typical tasks its users are likely to perform and bring to focus some of the challenges that the workflows implementors face during its design and delivery, highlighting the importance of interoperability. We will then cover the benefits that the wider adoption of IS-12 specification has for the broadcast community e.g., where vendors adopt it within their future ST 2110 platforms and it becoming the de facto API for Broadcast controllers to provide run time device configuration and control of individual parameters.
Overall, attendees of this talk will come away with a greater understanding and the significance of the IS-12 specification, what an IP future looks like using SMPTE 2110 and NMOS standards and the benefits of achieving interoperability for the wider industry.
RIST on Demand Enhances IPMX in Network's Production and Monitoring Streams
Sergio Ammirata, Sipradius
We look at a solution crafted for one of the big three U.S. networks for sharing and monitoring of services and production streams created in North America and Europe. SDI, MPEGTS and SMPTE ST 2110 sources are encoded at either New York or London facilities to h264 (6 and 3 Mbps). The services are then forwarded freely to other locations via RIST Error Correcting Transport Protocol, using libRIST. At the receiving facilities, a media server solution comprising several virtual servers reads the RIST directly using a new concept we have coined as RIST On-Demand. The media servers then serve MPEG/TS or WebRTC to a mix of engineers, general staff and network personnel, some of whom work remote and others at the production facility. The media servers additionally relay the RIST to headquarters locations using dedicated RIST enabled players. The resulting IPMX is both high quality and low latency.
Cloud-Based Live Production: How To Orchestrate a Multi-Vendor Environment in the Cloud
Thomas Gunkel, Skyline Communications
This presentation discusses a case study, developed together with Grass Valley and RTS, of how multiple hybrid/cloud-native solutions from different vendors are managed together to make cloud-based productions as easy as they were in the past using on-premises infrastructure. The first part presents the underlying architecture, which is based on media services blueprints. Those include a set of virtual functions (e.g. a playout or multi-viewer function) and also describe how the functions get connected to each other. Profiles are defined to apply different configurations to a virtual function. A resource management layer maps resources that are available and have the capabilities and the required capacity to execute the live production. Mediation translates the profile parameters into the required API calls to ensure that solutions from different vendors can be used independently of the supported protocols. The 2nd part discusses the entire lifecycle management of a production and how a CI/CD approach is used to automate things as much as possible: enter planning data, deploy/configure resources, present control surfaces, monitor the event and finally decommission resources again.
