Video: RIST in the Cloud

Cloud workflows are starting to become an integral part of broadcasters’ live production. However, the quality of video is often not sufficient for high-end broadcast applications where cloud infrastructure providers such as Google, Oracle or AWS are accessed through the public Internet or leased lines.

A number of protocols based on ARQ (Adaptive Repeat reQuest) retransmission technology have been created (including SRT, Zixi, VideoFlow and RIST) to solve the challenge of moving professional media over the Internet which is fraught with dropped packets and unwanted delays. Protocols such as a SRT and RIST enable broadcast-grade video delivery at a much lower cost than fibre or satellite links.

The RIST (Reliable Internet Streaming Transport) protocol has been created as an open alternative to commercial options such as Zixi. This protocol is a merging of technologies from around the industry built upon current standards in IETF RFCs, providing an open, interoperable and technically robust solution for low-latency live video over unmanaged networks.

In this presentation David Griggs from Amazon Web Services (AWS) talks about how the RIST protocol with cloud technology is transforming broadcast content distribution. He explains that delivery of live content is essential for the broadcasters and they look for a way to deliver this content without using expensive private fibre optics or satellite links. With unmanaged networks you can get content from one side of the world to the other with very little investment in time and infrastructure, but it is only possible with protocols based on ARQ like RIST.

Next, David discusses the major advantages of cloud technology, being dynamic and flexible. Historically dimensioning the entire production environment for peak utilisation was financially challenging. Now it is possible to dimension it for average use, while leveraging cloud resources for peak usage, providing a more elastic cost model. Moreover, the cloud is a good place to innovate and to experiment because the barrier to entry in terms of cost is low. It encourages both customers and vendors to experiment and to be innovative and ultimately build more compelling and better solutions.

David believes that open and interoperable QoS protocols like RIST will be instrumental in building complex distribution networks in the cloud. He hopes that AWS by working together with Net Insight, Zixi and Cobalt Digital can start to build innovative and interoperable cloud solutions for live sports.

Webinar: AWS – Behind the Stream

Date: November 14, 2019 / 8am PST / 11am EST / 16:00 GMT

Behind The Stream is an online show containing three webinars designed for sports media broadcasters, athletic teams, and digital rights holders.

The first of the three sessions here covers creating the right experience for the service. Particularly in sports, there are different ways to present graphics and stats, to have interactivity and to innovate in order to keep the audience with you and interested.

The second session is an intriguing look into using machine learning to analyse the video to create metadata, including player tracking and then how to process and display that data to add an extra layer of interest for the audience.

Lastly, but the longest session of the three, is an hour spent whiteboarding the streaming system itself, how the different elements in the cloud work together and the things to look out for when implementing this for yourself.

Whilst these sessions are specifically about AWS services, much of the principles can be carried over to other cloud providers. With this factor and AWS being synonymous, for many, with ‘cloud’, learning the AWS way of doing things is a fantastic way to learn about operating in the cloud in general.

Video: AWS Networking Fundamentals

Networking in the cloud, by rights, should be the same in your office but with it’s a lot easier when you’re led through it. From subnets to VPN’s, this talk from AWS makes sure you can get your VPC (Virtual Private Cloud) talking to other parts of your cloud infrastructure and your office.

Starting with the basics and building up, Perry and Tom take us through the IP address allocation, address choices, firewall configuration, security configuration and then on to Direct Connect, VPNs sharing VPC resources and much more.

From the AWS Summit 2019, this is a great talk for those who know networking well and are new to AWS, as well as those who are comfortable with AWS names, but are a little rusty on the finer points of networking.
