Prerequisite knowledge

  • A general understanding of networking for the web

What you'll learn

  • Discover approaches that can help solve the issues presented by WebRTC and HTTP livestreaming using existing techologies


A lot of app developers right now are taking cues from HQ Trivia and adding the ability for viewers to interact with livestreamers in relative real time through chat, answering questions, betting, bidding, and more. They are all currently running into the same challenge of bringing the latency of live-streaming video down while syncing up interactions between the livestreamer and thousands of viewers.

There’s currently a race between WebRTC-based approaches, which are very low in latency but hard to scale, and HTTP-based approaches, which are easy to scale but higher in latency. Neither are great. Steve Heffernan details available approaches as well as the standards-based approaches that will soon help solve the issue using technologies that are already available to us.
