RIST Enhances IPMX in Network's Production and Monitoring Streams
Sergio Ammirata - SipRadius LLC
With Internet Protocol Media Experience (IPMX) being the latest buzzword, we look at a solution crafted for one of the big three U.S. networks for sharing and monitoring of feeds and production streams created in North America and Europe. SMPTE ST 2110 (typically 3.0 and 1.5 Gbps) are encoded at either New York or London facilities to h264 (6 and 3 Mbps). They are then forwarded to the opposite side via RIST Error Correcting Transport Protocol, using libRIST. At the receiving end, a Media Server solution comprising several virtual servers reads the RIST directly. The Media Servers then serve MPEG/TS or WebRTC to a mix of engineers and other network personnel, some of whom work from home, others at the production facility. The Media Servers additionally relay the RIST to headquarters locations, where set top boxes and PCs have RIST enabled VLC viewers. The resulting IPMX is both high quality and low latency. The talk shall complement a demo at the VSF booth, which we will call "RIST on Demand." The talk will attempt to show the on demand aspect -- in bandwidth savings, scalability, etc. -- that the solution just described entails.

A Master's Toolbox and Algorithms for Low-Latency Live Streaming
Ali C. Begen – Comcast-Ozyegin University
Today, a glass-to-glass latency of 10-30 seconds is practically achievable in live streaming and such a range is acceptable in most cases. Yet, the increasing number of cord-cutters is putting pressure on streaming providers to offer low-latency (2-10 seconds) streaming, especially for sports content. In the last few years, the streaming industry produced a number of solutions. At the high level, there are common features across all these solutions but there are also obvious as well as subtle differences in their requirements and implementations. Independent of the technology, low-latency live streaming brings up new challenges. This talk covers some of these aspects, shows examples and surveys various efforts that are underway in the streaming industry.

How SMPTE ST2110 Technologies will Facilitate the Spread of Next Generation Audio Codecs
Thomas Burnichon - ATEME
While the initial goal of SMPTE ST2110 standards was to make the production workflows more cost-effective and future-proof by replacing aging SDI infrastructures, these IP based technologies could even go further, leading to major content production headway for broadcasters, but also consumption experience improvements for the end users.
ST2110 based production workflows allow simpler and faster interconnectivity between production equipment, regardless of the distance between them and thus facilitating cloud-based end to end deployments. Also, the type and rate of data transmitted over the link is now practically unlimited, breaking through a major bottleneck imposed by legacy SDI and its constant bit rate point to point link model.
This paper describes and breaks down a ST2110 based live production workflow, with emphasis on how these technologies address advanced Next Generation Audio codecs scenarios such as Immersive Audio, High Order Ambisonics and dynamic configuration changes, from authoring to delivery steps. The live production workflow pertains to distributing highly immersive live sport events and music concerts to the widest audience while offering a personalized example.

Cloud-Based Live Productions - How to Orchestrate a Multi-vendor Environment in the Cloud
Thomas Gunkel – Skyline Communications
Synopsis: 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.
> IPMX Demonstration
This Internet Protocol Media Experience (IPMX) demonstration presents several aspects of the Technical Recommendation TR-10. Hardware and Software based IPMX Senders (Encoders) and IPMX Receivers (Decoders) from various companies taking part in this demonstration are implementing the System Timing as per TR-10-1. The network in this demonstration contains no PTP Grand Master in order to demonstrate that IPMX devices can operate without PTP present in the network. All video sources in this demonstration are asynchronous and part of the exhibit shows the low latency that is possible between the input signal of an IPMX Sender and the output of the IPMX Receiver.

Private 5G Networks at the Queen's funeral and elsewhere
Kieran Kunhya – Open Broadcast Systems
The Queen's funeral led to an unplanned, real-world use of a Private 5G network as the primary broadcast path during her departure from Scotland. This presentation will go into the technical details behind this world-first broadcast, which was the first known use of a Private 5G network for TV news and also the first known use of a private 5G network at an airport. It came at a challenging time for resources in the UK as there was a shortage of staff and equipment during this major event, which also clashed with IBC. It will also explain how the Private 5G network was used at the Pitlochry Highland Games a few days before and also at IBC. Private 5G has many promising applications and this presentation will explore how it can be used in the future.

Making multi-vendor cloud-based production just work
Chris Lennon – Ross Video
The move to the cloud for production (and other aspects of media) in undeniable.
While the top priority during the pandemic was staying on air, media organizations are now focusing on making the multi-vendor reality of cloud production work as smoothly as possible. And what about ground to cloud and cloud to ground? The reality is that a hybrid environment for production is one in which we will live for quite a while.
A new open standards and open source initiative, Catena, promises to evolve what was previously learned in on-premises interoperability to the cloud, with proven technology and approaches, coupled with new capabilities centered around industry-accepted technologies and approaches. We will examine what Catena is, and the promise it brings to multi-vendor cloud based production (and other parts of media).

RIST Source Adaptation
Ciro Noronha, Ph.D. – Cobalt Digital
The RIST AG has recently published TR-06-4 Part 1, Source Adaptation. The TR defines a mechanism whereby devices receiving a RIST stream can provide feedback to senders on the current network conditions. Using these messages, the sender can adapt to the current conditions either by adjusting the stream bit rate, or by adjusting the stream routing if multiple links are available. This presentation will provide an overview of TR-06-4 Part 1, followed by some initial test data over actual Internet links.

Unified System Design: Physical and Logical Design
Lukas Odhner - NTC, a Deloitte Business
Longstanding approaches to system documentation based on AutoCAD drawings are not keeping up with the transition to IP infrastructure. As systems move into the virtual realm signal flow has less and less correlation to physical cables. New approaches are required to design and build modern media systems. NTC, a Deloitte business, is confronting this challenge by building on new open source tools (namely Netbox) to create a design and documentation database that unifies the physical and logical designs into a shared single source of truth. We will share the approaches used in multiple large projects and how leveraging the approaches of the IT industry can streamline ST-2110 and all media network designs. The data-driven design approach that we will share increases design engineering efficiency to enable media systems to be faster and with more precision. Our experience has shown that it also enables better communication between stakeholders with joint responsibility for maintaining media infrastructure. We look forward to sharing more about what we have learned through the process of rethinking media system design processes.

Bringing Distributed Hybrid IP Production Technologies Together – Overcoming Current Performance Limitations
Andy Rayner - Nevion
The evolution of live production is a hybrid of appliance and compute processing, located both locally and remotely, hosted on both private and ‘public’ infrastructure.
This in turn enables people - engineering & talent to be distributed.
There are additionally a wealth of compute/AI/ML tools currently the preserve of non-linear post production that have the potential to become used in mainstream live production.
In this presentation, we will examine the outworking of this production evolution, the current deployment scenarios and what potential the future holds.
We will look at what performance restrictions of current deployments are due to implementations and which are due to fundamental scientific limitations.
We will also look at the tool kit of existing Technical Recommendations from VSF as well as other organizations and we will also consider what outstanding areas of TRs could be needed to complete future solutions.

Advance techniques for monitoring Live video delivery- why Video delivery intelligence is important?
Adi Rozenberg - AlvaLinks Media System
IP based transport is becoming the new backbone of our industry; Live ingest, content acquisition and transport to the cloud and in the cloud.
Protocols like RIST, SRT, NDI, JpegXs and ST2110 have easy setup but they still require dedicated Link evaluation and very accurate measurement of the network behavior. something that the standard IT tools don't offer. How do I troubleshoot a problem when it arises? What do I need to monitor? Keep track of? And what are the option in my bag of tricks to identify a problem, isolate and avert it?
IP networks are complex "living organisms" that are dynamic and have unpredictable behavior and performance. Routes can change, flows can join, elements may get congested. The cloud is yet another challenge that we need to overcome. How are we monitoring network that are not under our control or visibility?
The presentation will address these question head-on and present open source tools and what is missing to fill the void.
