Multicast ABR

Multicast ABR (May)

Wednesday, May 2, 2018 at 10:00am (PST)

When it comes to online streaming, we live in a unicast world. And that’s a problem. As more consumers gravitate towards anytime, anywhere video consumption, the capacity to serve single streams of high-quality video content to millions of viewers reaches its breaking point. The question is whether multicast ABR is the solution or just a technological unicorn. In this panel, you’ll learn about the differences between unicast and multicast, how multicast ABR might be achieved (and under what conditions) using a variety of technologies such as LTE-B, and the challenges that may keep this solution from ever coming to fruition.

Topics Covered

This webinar will address (or addressed) the following:

  1. What is Multicast ABR? How does it work?
  2. What are the primary use cases for M-ABR? Where does it work really well? Where does it fail?
  3. What are the benefits of M-ABR? To the operator? To the viewer?
  4. How do we make M-ABR work in today’s heterogenous delivery environments? (i.e., Internet + ISP network/mobile + home network)
  5. What are the technical “gotchas” for implementing M-ABR? What do network operators have to keep in mind when considering deployment?
  6. Have we seen any deployments today? If not, why not?
  7. The industry has been talking about M-ABR for several years now. What is the primary obstacle to seeing widespread deployment?
  8. What needs to still happen before M-ABR will become a reality?
  9. How does M-ABR work in conjunction with other streaming latency-reducing technologies like WebRTC? Is it needed? Are these approaches mutually-exclusive? Is M-ABR just one component of the overall solution to reducing delivery latency or is it the “silver bullet?”
  10. Will M-ABR be needed when 5G is widely deployed?
  11. What is the one piece of advice you can give network operators considering deployment of M-ABR?
