Reducing Stream Latency

Reducing Stream Latency (June)

Thursday, June 27, 2019 at 10:00am (PST)

Consumers have been spoiled by traditional broadcast television—they sit on the couch, grab the remote, press the power button, and, WHAM, TV jitter free and without delay. But that’s not always the case with streaming video. Travelling over an unmanaged network like the Internet, streaming can be subject to an innumerable number of small events that can add up to a lot of latency. And, especially when it comes to live events like sports, any kind of latency can turn viewers off from the streaming experience. In this webinar, we’ll explore some of the ways that video distributors can reduce stream latency and a few of the best practices being employed by some of the biggest streamers on the planet.

Topics Covered

This webinar will address (or addressed) the following:

  1. When it comes to streaming video, what is latency? What isn’t? Should the industry be focusing on “glass-to-glass” or just “cache-to-glass?”
  2. Caching can significantly reduce round-trip time, but what happens when there’s a cache miss? What can be done to improve caching efficiency and the time to fetch content from origin?
  3. Can choices made during encoding reduce, or add to, latency? What are some of the best practices regarding chunk size and other profile variables?
  4. HLS, probably the most widely used HTTP chunked streaming container, has always had an issue with latency. What does Apple’s new LHLS promise in terms of reducing latency and what does it mean for video distributors who want to adopt it?
  5. There are a number of competing protocols floating around to help accelerate the delivery of streaming video: QUIC (HTTP/2), SRT, WebRTC, etc. How can, and will, these protocols help reduce latency?
  6. What part does hardware play in reducing stream latency? Will the “edge” make a difference?
  7. How do new technologies like 5G (both fixed and mobile) and ATSC 3.0 play a role in reducing latency? Is the answer to a better viewing experience just more bandwidth?
  8. What’s the state of Multicast ABR? Can it ever be used over the Internet? Can it prove useful within operator networks?
  9. With so many components potentially impacting latency, is it even possible to get a complete picture of what’s impacting stream performance? How do you measure all this? What are the KPIs?
  10. Where will streaming latency be in two-year’s time? The same? Better? Worse? Can streaming latency ever come close to broadcast?
