Webinar: Multicast ABR opens the door to a new DVB era

Now available on demand

With video delivery constituting the majority of traffic, it’s clear there’s a big market for it. ON the internet, this is done with unicast streaming where for each receiver, the stream source has to send another stream. The way this has been implemented using HTTP allows for a very natural system, allied Adaptive Bit Rate (ABR), which means that every when your network capacity is constrained (by the network itself or bandwidth contention), you can still get a picture just at a lower bit rate.

But when extrapolating this system linear television, we find that large audience place massive demands on the originating infrastructure. This load on the infrastructure drives its architects to implement a lot of redundancy making it expensive to run. Within a broadcaster, such loads would be dealt with by multicast traffic but on the internet, Multicast is not enabled. For an IPTV system where each employee had access via a program on their PC and/or a set-top-box on their desk, the video would be sent by multicast meaning that it is the network that was providing the duplication of the streams to each endpoint, not the source.

By combining existing media encoding and packaging formats with the efficiency of point-to-multipoint distribution to the edge of IP-based access networks, it is possible to design a system for linear media distribution that is both efficient and scalable to very large audiences, while remaining technically compatible with the largest possible set of already-deployed end user equipment.

This webinar by Guillaume Bichot which is in place of his talk at the cancelled DVB World 2020 event explains DVB’s approach to doing thus that; combining multicast ordination of content with delivery of an ABR feed, called DVB-mABR.

Video broadcast has been digitised since it’s initial broadcasts in the 30s, and more than once. In Europe, we have seen IP carriage (IPTV) services and most recently the hybrid approach where broadband access is merged into transmitted content with the aim of delivering a unified service to the viewer called HbbTV. Multicast ABR (mABR) defines the carriage of Adaptive Bit Rate video formats and protocols over a broadcast/multicast feed. Guillaume explains the mABR architecture and then looks at the deployment possibilities and what the future might hold.

mABR comprises a multicast server at the video headend. This server/transcaster, receives standard ABR feeds and then encapsulates it into multicast before sending. The decoder does the opposite, removing any multicast headers revealing the ABR underneath. It’s not uncommon for mABR to be combined with HTTP unicast allowing the unicast to pick up the less popular channels but for the main services to benefit from multicast.

Guillaume explores these topics plus whether mABR saves bit rate, how it’s deployed and how it can change in the future to keep up with viewers’ requirements.

Webinar: Scaling Video Delivery

There is no doubt that streaming video is here to stay. Every month, more consumers log into and subscribe to one or more OTT services. But as those services grow beyond geographical borders, providers are forced to ensure that their offerings can meet the demands of a swelling user base located around the world. Given that this involves employing the public Internet to deliver video to different pockets of the globe, OTT operators often struggle with implementing the best video delivery architecture: what infrastructure to purchase, to install, where & which partners to employ, and how to ensure the best possible viewer experience. This webinar explores some of the proven methods for scaling video delivery as well as best practices employed by some of the world’s biggest streamers.

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: Content Delivery Challenges in a New Era


Streaming Media discusses moving away from Flash and the alternatives. Viewers want better viewing experiences than ever, meaning CDNs have to stay one step ahead. This prompts a move to HTML5 delivery, an emphasis on live streaming, and a commitment to lower latency than ever before – with all this on any device.
This webinar will bring you up to date on the cutting edge of content delivery, with a focus on the following topics:

  • Why enterprise streaming professionals need to develop a strategy for transitioning away from Flash
  • From Flash-free to plugin-free: live encoding and playback on any device
  • Interactive live streaming: Live video and audio has turned away from broadcast towards two-way or multi-directional communication
  • Why an agnostic content delivery strategy is a must for live streaming inside the enterprise
  • Scalable distribution of ultra-low-latency live streams worldwide
  • The importance of utilizing solutions that can analyze the quality of the live streaming viewing experience
