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.

In this webinar Limelight discuss some of the challenges with delivering low latency video and take a deeper dive to look at what causes latency, the WebRTC protocol and how Limelight Networks delivers real-time streaming at global scale.
Topics that will be discussed during this webinar include:
Challenges delivering low-latency video
Various approaches for reducing latency (small chunk HLS, peer-to-peer, WebRTC)
Encoding and codecs
Stream access and security
How to implement interactivity into live streaming video

Webinar: Thursday, December 7 – 11:00am PT / 2:00pm ET / 19:00 GMT
Keith Weinberger from Limelight with colleague Charles Kraus discuss latency. As viewers spend more time online watching live and on-demand video content, broadcasters and content distributors are under increasing pressure to deliver an exceptional low-latency live video streaming and on-demand experience, on any device.
Join the video delivery experts from Limelight Networks when they share strategies for implementing a cost-effective solution at global scale, without sacrificing the quality your audiences expect. They will also discuss how to:
Deliver live video at 3 to 5 second latencies through HLS and DASH chunked streaming techniques or sub-second latencies through emerging WebRTC technology
Reach the widest possible audience with multi-device streaming
Optimize all points in your video workflow to ensure broadcast-quality experiences
