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.
Super Bowl 53 has come and gone with another victory for the New England Patriots. CBS Interactive responsible for streaming of this event built a new system to deal with all the online viewers. Previously they used one vendor for acquisition and encoding and another vendor for origin storage, service delivery and security. This time the encoders were located in CBS Broadcast Centre in New York and all other systems moved to AWS cloud. Such approach gave CBS full control over the streams.
Due to a very high volume of traffic (between 30 and 35 terabits) four different CDN vendors had to be engaged. A cloud storage service optimized for live streaming video not only provided performance, consistency, and low latency, but also allowed to manage multi-CDN delivery in effective way.
In this video Krystal presents a step-by-step approach to creating a hybrid cloud/on premise infrastructure for the Super Bowl, including ad insertion, Multi-CDN delivery, monitoring and operational visibility. She emphasizes importance of scaling infrastructure to meet audience demands, taking ownership of end to end workflow, performing rigorous testing and handling communication across multiple teams and vendors.
Webinar Date: Thursday May 30th 2019
Time: Duration 4 hours. 7am PT / 10am ET / 15:00 BST
AWS is synonymous with cloud computing so an insight into managing media on AWS is an insight into cloud computing in general. AWS is offering a 4-hour showcase of implementing content creation, distribution and your supply chain in the cloud.
The online event starts with a keynote on the motivations for moving your workflows into the cloud and how AWS meets them. After that, there are 3 tracks which track the 3 topics.
The complete list is available here. AWS Elemental dominates the distribution track explaining the use cases that can be met and going through the many in-cloud transcoding options.
The creation and supply chain tracks finish with a customer spotlight from FuseFX and Deluxe respectively. For anyone considering a move to the cloud for any part of their operation, these sessions should shed light on what is actually achievable and what is still wishful thinking.
AWS is synonymous with cloud computing and whether you use it or not, knowing how to do things in AWS reaps benefits when trying to understand or implement systems in a cloud infrastructure. Knowing what’s possible and what others are doing is really useful, so whilst I don’t usually cover heavily product-specific resources here on The Broadcast Knowledge I still believe that knowing AWS is knowing part of the industry.
Here, there are 3 consecutive webinars which cover building a live streaming channel from the fundamentals through to making it operational and ongoing monitoring and maintenance.
Session one at 3pm GMT looks at end-to-end workflows and strategies for redundancy. It looks at both contribution of video into the cloud as much as what happens when it arrives and the delivery.
Session two at 4pm GMT looks examines the more complex workflows where you spread processing/failover across multiple regions and other similar situations.
Session three is the last of the day at 5pm GMT looking at setting up end-to-end monitoring to take the guesswork out of delivering the service on an on-going basis.
