RIST is all about the combination of interoperability and innovation that provides an open, interoperable, and technically robust solution for low-latency live video over unmanaged networks. RIST is developed jointly by a large group of experts, pouring hundreds of years of real-world experience into the specifications as well as on top of existing RFC standards.

Join us to see how hundreds of years of experience created the protocol of choice for video delivery over the Internet. Learn about RIST advances as well as about the promising roadmap of RIST.

1.00-1.30pm: Cobalt – RIST Main Profile Overview

VSF TR-06-1, RIST Simple Profile, was published in October 2018 after a very successful demo at IBC. It provides low-latency communication over the Internet, with advanced methods for packet recovery. Now, the work on the follow-up specification, VSF TR-06-2, RIST Main Profile, is nearing completion. RIST Main Profile adds the following features to RIST Simple Profile:

  • Authentication and Encryption: ensures that the endpoints are who they say they are, and protects the stream in transit.

  • Tunneling and Multiplexing: allows multiple streams to share a single RIST connection.

  • Support for in-band traffic and/or control: allows generic traffic to be mixed with RIST streams

  • Bandwidth Optimization through NULL packet deletion and re-insertion

  • Support for high bit rate/high latency links

This presentation will cover the main features of the upcoming RIST Main Profile and the technologies behind it.

Presenter: Ciro Noronha, Director of Technology Compression Systems, Cobalt Digital

1.30-2.00pm: DVEO - Encryption with PSK (Pre-shared Keys)

The main profile provides two methods of protection for your RIST streams: DTLS (UDP version of TLS, the authentication and encryption method used on the web) and Pre-Shared Key (PSK). The typical DTLS use case is for scenarios requiring authentication and encryption in a one-transmitter-to-one-receiver bidirectional network.

The focus of this presentation is on scenarios where traditional DTLS cannot be used, and one needs a Pre-Shared Key solution. We describe three such scenarios where PSK must be used. Firstly, where no real-time clock is available on one side or the other. Secondly, in any one-transmitter-to-many-receiver scenario, including multicast. And finally, in any network lacking the physical ability for two-way communications, such as a one-way satellite link. We will also consider the role Forward Error Correction (FEC) plays in these scenarios.

Presenter: Sergio Ammirata, CTO, DVEO

2.00-2.30pm: Video Flow - Adaptivity (future RIST capability)

Adaptation is critical to maintaining service continuity and in particular, over the internet. Unlike high SLA services, the Internet cannot guaranty the bandwidth due to network or user behavior, including oversubscription, network congestion, and local service problems.

However, combining dynamic link bonding and adaptivity in real time can reach reliability levels similar to those of a satellite link or a fiber connection. This presentation explains both how dynamic bonding is making use of multiple Internet links and other mediums to achieve higher reliability levels and how adaptive delivery and dynamic MPTS adaptation in real time will make sure that premium services stay on-the-air.

Learn why the Internet cannot guarantee bitrate, how dynamic bonding adds stability and reliability to video delivery over the Internet, why adaptivity is imperative to ensuring the reliability of your premium services and how to enhance service reliability over the Internet.

Presenter: Adi Rozenberg, Co-Founder and CTO, VideoFlow

2.30-3.00pm: Net Insight - RIST for high-end live media workflows

With new support for higher bandwidth services introduced in the RIST main profile, RIST can now be used also for high-end (and as a consequence higher bandwidth) workflows such as low-latency contribution using JPEG 2000 compression (instead of HEVC/AVC), and remote production with stringent low-latency requirements that also use JPEG 2000.

Net Insight has been providing broadcasters and production companies with high-quality JPEG 2000 based live transport solutions for contribution and remote production for many years, and have seen an increasing interest in moving also these high-end workflows to simpler and more cost-efficient infrastructure. Infrastructure, such as leased enterprise-grade lines or even the public Internet, that comes with challenging characteristics and impairments from high levels of continuous packet drop. With the addition of high bandwidth support in RIST main profile, RIST can now be used to provide broadcast quality lossless transport over such lossy infrastructure.

This presentation explains how one of the new features in the RIST main profile, support for higher bandwidth services, enables even more use cases and live workflows to move to simpler and more cost-efficient infrastructure. The presentation furthermore explains the requirements from broadcasters and production companies for high quality transport in live production workflows, based on many years of real-world experience.

Presenter: Love Thyresson, Head of Internet Media Transport, Net Insight

3.00-3.30pm: Open Broadcast Systems - RIST for delivering content to tens of millions

In late-2018, Open Broadcast Systems added RIST support to its encoder and decoder products, replacing a similar protocol. Subsequently, a number of customers deployed the technology in various locations around the world and provided immediate feedback.

This presentation will talk about some of the workflows involved and the benefits of using RIST compared to other solutions (e.g bonding, monitoring with tcpdump).

It will also cover future workflows such as cloud ingest, rewrap and distribution of content that we intend to support.

Presenter: Kieran Kunhya, Founder, Open Broadcast Systems

3.30-4.00pm: AWS - How RIST and the cloud are transforming content distribution

Transport Stream over IP is now a top-of-mind consideration when it comes to live content distribution. Learn how RIST and AWS Elemental are transforming the landscape of terrestrial distribution by giving customers secure, reliable software distribution technologies, deployable in minutes, to solve content distribution challenges on a global scale.

UDP/IP is, by design, an unreliable way to move live video data from one location to another. In this session, we’ll look at why RIST is transformative when it comes to terrestrial content distribution strategies. We’ll also look at how RIST plus the reach of the AWS cloud can be powerful combination for moving for your live video content from one part of the world to the other.

Presenter: David Griggs, Senior Product Manager Media Services, AWS Elemental
