Video: Low Latency and High QOE for Live Streaming


Low latency streaming is always a compromise, but what can be done to keep QOE high?

This on-demand webinar looks at CMAF and presents some real-world data on this low latency technique. The webinar starts by explaining that CMAF is a low-latency streaming technology similar to HLS and other streaming protocols where the idea is to deliver the video as small files. Olivier and Alain from Harmonic explain how this is done and look at some of the trade-offs and compromises that are needed and introduce techniques to keep QOE high. They also look at deployment in cloud vs. on premise.

Pieter-Jan Speelmans talks about play tradeoffs and optimisations within the player. CMAF allows the buffer to be reduced and whilst a bad network may mean you buffer is similar to ‘normal’, but in good networks, this buffer can be brought down significantly. He also talks about how ABR switching is impacted by GOP length even in CMAF.

Viaccess-Orca explains how DRM works with CMAF and looks at some of the challenges including licences acquisition time and overloading licence servers at the beginning of events. Akamai’s Will Law explains some benefits of CMAF and the near-real-time of chunk-based transfer (HTTP 1.1) and how downloading chunks at full speed leads to problems when the same broadband link is used by several clients.

There are lots of good talks on CMAF, but this is one of the few which talks about CMAF not as theory, but as is deployable today.

Webinar: Low-Latency CMAF vs. WebRTC

CMAF brings low latency streams of less than 4 seconds into the realms of possibility, WebRTC pushes that below a second – but which is the right technology for you?

Date: June 12th 2019 Time: 11am PST / 2pm EST / 19:00 BST

CMAF represents an evolution of the tried and tested technologies HLS and DASH. With massive scalability and built upon the well-worn tenants of HTTP, Netflix and a whole industry was born and is thriving on these still-evolving technologies. The push to reduce latency further and further has resulted in CMAF which can be used to deliver streams with five to ten times lower latencies.

WebRTC is a Google-backed streaming protocol with the traditional meaning of streaming; it pushes a stream to you a opposed to the HLS-style methods of making small files available for download and reassembly into a stream. One benefit of this is extremely low bitrates of 1 second or less. Used widely by Google Hangouts and Facebook messenger, WebRTC is increasingly an option for more broadcast-style streaming services from live sports & music to gaming and gambling.

Both have advantages and draw-backs so Wowza’s Barry Owen and Anne Balistreri are here to help navigate the ins and outs of both technologies plus answer your questions.

Video: An Overview of the ISO Base Media File Format

ISO BMFF a standardised MPEG media container developed from Apple’s Quicktime and is the basis for cutting edge low-latency streaming as much as it is for tried and trusted mp4 video files. Here we look into why we have it, what it’s used for and how it works.

ISO BMFF provides a structure to place around timed media streams whilst accommodating the metadata we need for professional workflows. Key to its continued utility is its extensible nature allowing additional abilities to be added as they are developed such as adding new codecs and metadata types.

ATSC 3.0’s streaming mechanism MMT is based on ISO BMFF as well as the low-latency streaming format CMAF which shows that despite being over 18 years old, the ISO BMFF container is still highly relevant.

Thomas Stockhammer is the Director of Technical Standards at Qualcomm. He explains the container format in structure and origin before explaining why it’s ideal for CMAF’s low-latency streaming use case, finishing off with a look at immersive media in ISO BMFF.

Video: Understanding Video Performance: QoE is not QoS

Mux’s Justin Sanford explains the difference between Quality of Service and Quality of Experience; the latter being about the entire viewer experience. Justin looks at ‘Startup time’ showing that it’s a combination of an number of factors which can include loading a web page showing the dependence of your player on the whole ecosystem.

Justin discusses rebuffering and what ‘quality’ is when we talk about streaming. Quality is a combination of encoding quality, resolution but also whether the playback judders.

“Not every optimisation is a tradeoff, however startup time vs. rebuffering is a canonical tradeoff.”

Justin Sanford, Mux

Finally we look at ways of dealing with this, including gathering analytics, standards for measuring quality of experience, and understanding the types of issues your viewers care most about.

Webinar: Talking to the TV: Transforming the viewing experience with voice control

Thursday 16th May 2019, 16:00 BST / 11am EDT / 8am PDT

Controlling services by voice is on the rise. Recently we have seen Google move all their Nest hardware control into Google Assistant and the abilities of Alexa and Siri continue to grow. All of these smart speakers and voice-controlled AI assistants have seen rapid adoption in homes, the UK being the biggest adopter with voice assistant devices now used in more than a quarter of all households.

With a shift away from the on-screen EPG and clunky remote controls to a world where any content is a voice command away, who owns the voice interface with the consumer and the vast amount of valuable data it creates? Does this put more power in the hands of the Silicon Valley tech giants as their voice assistants and AI algorithms become a new gatekeeper? And how should content owners respond?

This webinar explores the value of voice control for content, and finds the best strategies for broadcasters and platform operators to develop voice interfaces and maintain control of the user experience.

Video: Per-title Encoding at Scale

MUX is a very pro-active company pushing forward streaming technology. At NAB 2019 they have announced Audience Adaptive Encoding which is offers encodes tailored to both your content but also the typical bitrate of your viewing demographic. Underpinning this technology is machine learning and their Per-title encoding technology which was released last year.

This talk with Nick Chadwick looks at what per-title encoding is, how you can work out which resolutions and bitrates to encode at and how to deliver this as a useful product.

Nick takes some time to explain MUX’s ‘convex hulls’ which give a shape to the content’s performance at different bitrates and helps visualise the optimum encoding parameters the content. Moreover we see that using this technique, we see some surprising circumstances when it makes sense to start at high resolutions, even for low bitrates.

Looking then at how to actually work out on a title-by-title basis, Nick explains the pros and cons of the different approaches going on to explain how MUX used machine learning to generate the model they created to make this work.

Finishing off with an extensive Q&A, this talk is a great overview on how to pick great encoding parameters, manually or otherwise.

Video: Using CMAF to Cut Costs, Simplify Workflows & Reduce Latency

There are two ways to stream video online, either pushing from the server to the device like WebRTC, MPEG transport streams and similar technologies, or allowing the receiving device to request chunks of the stream which is how the majority of internet streaming is done – using HLS and similar formats.

Chunk-based streaming is generally seen as more scalable of these two methods but suffers extra latency due to buffering several chunks each of which can represent between 1 and, typically, 10 seconds of video.

CMAF is one technology here to change that by allowing players to buffer less video. How does this achieve this? An, perhaps more important, can it really cut costs? Iraj Sodagar from NexTreams is here to explain how in this talk from Streaming Media West, 2018.

Iraj covers:

  • A brief history of CMAF (Common Media Format)
  • The core technologies (ISO BMFF, Codecs, captions etc.)
  • Media Data Object (Chunks, Fragments, Segments)
  • Different ways of video delivery
  • Switching Sets (for ABR)
  • Content Protection
  • CTA WAVE project
  • Wave content specifications
  • Live Linear Content with Wave & CMAF
  • Low-latency CMAF usage
  • HTTP 1.1 Chunked Transfer Encoding
  • MPEG DASH

Video: OTT Moves Toward Microservices


 

Using microservices is a way of architecting your software platform to be nimble, simple and is just as applicable to on-premise platforms as cloud. As scaling is important for OTT providers, it’s not surprising that much work is being done in the OTT sector to utilise microservice architectures.

Even companies that are not yet actively operating on a microservices architecture are looking for vendors who at least have a strategy to cater to it for the future. This session will examine the core benefits (including redundancy, dev ops, scalability, and self-healing), the different approaches (including containerisation and orchestration via Docker, Kubernetes, and Mesos, as well as native microservices models like Erlang), and the complexities of migrating a generic architecture to a microservices architecture.

This panel covers:

    • Why is OTT so suited to microservices?
    • How microservices enable companies to be flexible to changing customer demands
    • How microservices reduce complexity
    • Benefits of continuous deployment

plus much more!
