Webinar: Low-Latency CMAF vs. WebRTC

Posted on by Russell Trafford-Jones

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: Sub-Second Live Streaming: Changing How Online Audiences Experience Live Events

Posted on by Russell Trafford-Jones

There are two main modern approaches to low-latency live streaming, one is CMAF which used fragmented MP4s to allow frame by frame delivery of chunks of data. Similar to HLS, this is becoming a common ‘next step’ for companies already using HLS. Keeping the chunk size down reduces latency, but it remains doubtful if sub-second streaming is practical in real world situations.

Steve Miller Jones from Limelight explains the WebRTC solution to this problem. Being a protocol which is streamed from the source to the destination, this is capable of sub-second latency, too, and seems a better fit. Limelight differentiate themselves on offering a scalable WebRTC streaming service with Adaptive Bitrate (ABR). ABR is traditionally not available with WebRTC and Steve Miller Jones uses this as an example of where Limelight is helping this technology achieve its true potential.

Comparing and contrasting Limelight’s solution with HLS and CMAF, we can see the benefit of WebRTC and that it’s equally capable of supporting features like encryption, Geoblocking and the like.

Ultimately, the importance of latency and the scalability you require may be the biggest factor in deciding which way to go with your sub-second live streaming.

Video: WebRTC: The Future Champion of Low Latency

Posted on by Russell Trafford-Jones


With the continual quest for lower and lower latencies in streamed video, WebRTC is an attractive technology with latencies in the milliseconds rather than seconds. Limelight’s lowest latency offerings are based on WebRTC.

Alex Gouaillard from millicast explains the brief history and current status of WebRTC including which browsers are supported. After talking about optimisations that have been made, he talks about Bandwidth Adaptive Media and other use cases to be solved.

Supported codecs and, importantly, Scalable Video Coding support is discussed along with ways of implementing WebRTC. Alex also talks about the testing that’s gone in to the standard looking at bandwidth and latencies.

Lastly, a key question around WebRTC is ‘does it scale’ which is discussed before the conclusion.

Webinar: Deliver global sub-second live streaming experiences to increase viewer engagement

Posted on by Russell Trafford-Jones

Date: Thursday March 21st, 2019
Time: 15:00 GMT

With live online viewing delayed by up to 30 seconds or more compared to broadcast TV, enriching the viewing experience with online content, while ensuring that all viewers see the action at the same time, is a significant challenge. To provide viewers with engaging online experiences that keep them coming back for more, service providers need true real-time streaming.

This webinar will cover questions such as:

  • How important is latency for live online streaming?
  • Which live streaming workflows offers the greatest opportunity to generate additional revenue?
  • What are the main challenges faced by online video service providers when live-streaming major events such as sports tournaments?

Being a webinar from Limelight, you will also hear

  • How Limelight realtime streaming minimizes latency
  • How to reach the widest audience with native browser support
  • How to enable new business models with interactivity
  • How to reach viewers everywhere

All this along with key findings from DTVE’s industry survey, showing that industry executives believe live streaming could ultimately supplant broadcast technology, but challenges remain.
