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

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: ABR Streaming and CDN Performance

Hot on the heel’s of yesterday’s video all about Adaptive Bitrate (ABR) streaming we have research engineer Yuriy Reznik from Brightcove looking at the subject in detail. We outlined the use of ABR yesterday showing how it is fundamental to online streaming.

Brightcove, an online video hosting platform with its own video player, has a lot of experience of delivery over the CDN. We saw yesterday the principles that the player, and to an extent the server, can use to deal with changing network (and to an extent changing client CPU usage) by going up and down through the ABR ladder. However this talk focusses on how the CDN in the middle complicates matters as it tries its best to get the right chunks in the right place at the right time.

How often are there ‘cache misses’ where the right file isn’t already in place? And how can you predict what’s necessary?

Yuriy even goes in to detail about how to work out when HEVC deployment makes sense for you. After all, even if you do deploy HEVC – do you need to do it for all assets? And if you do only deploy for some assets, how do you know which? Also, when does it make sense to deploy CMAF? In this talk, we hear the answers.

Webinar: Video Delivery Trends


Date: Thursday February 28th 2019, 10am PT / 1PM ET / 18:00 GMT

Streaming continues to grow, in amount streamed, in people consuming it and in importance within this and other industries. One things which has always been an enabler yet made streaming harder to deploy is its rapid evolution. Whilst this has been a boon for smaller, nimbler companies – both content producers and service providers – the streaming has now arrived at most companies in one way or another and this breadth of use-cases has kept streaming tech moving forward and showing no signs of abatement.

Some aspects are changing. For instance we are seeing the first patent-free MPEG standard proposals (EVC, which has basic patent-free functionality and a better performing patent-controlled profile) on the heels of AV1. We’re seeing low-latency efforts such as CMAF taking hold as an alternative to WebRTC. With CMAF being much closer to the ever popular HLS, this may well beat out WebRTC in deployments at the cost of a slightly higher, but much improved latency.

To bring all of this in to focus for 2019, Jason Thibeault from the Streaming Video Alliance is bringing together a panel of experts to look at the coming trends and to give us an idea of what to look out for, and how to make sense, of 2019’s year of video delivery.

Webinar: Latency Still Sucks – So What Can You Do About It Today?

[Update]
An more recent panel event on this topic from Streaming Media is available on-demand

Date: Thursday 6th December, 2018. 11AM PT / 2PM ET / 19:00 GMT

Nobody wants to find out about a big play or major news event on Twitter before they see it in their video stream, so reducing latency is crucial for OTT services’ success. Likewise, ultra-low latency is crucial for interactive streaming applications. Depending on your use case, a few seconds of latency might be fine, or you might need to try to hit that sub-second target.

Learn which technologies and solutions are best for your business, and make sure your viewers get their video on time, every time. In this webinar, you’ll learn the following:

  • Why it’s important to evaluate and improve latency end-to-end, including software and services, encoder, platform, and player
  • How to decide which technology and solution is best for your use case (e.g. CMAF, HLS/DASH, WebRTC, Websocket)
  • How chunked CMAF offers a standards-based approach that allows latency to be decoupled from segment duration
  • How chunked CMAF leverages existing CDN HTTP capacity to provide low-latency solutions at high scale
  • How WebRTC can be used to deliver live video sub-second latency at scale, and provide rich, interactive experiences for live streaming applications
  • How a single misconfigured component can undo any other effort to achieve low latency
  • How integrated solutions create new business opportunities for low latency interactive use cases
  • How to achieve low latency across all platforms and devices
