Does the site support adaptive bitrate streaming?

Yes. For optimal viewing, adaptive bitrate streaming (ABR) runs in the background in a completely transparent mode. This enables your computing environment’s available bandwidth to be evaluated. It also enables our servers to deliver you the most efficient live stream for your computer to consume for clear uninterrupted viewing. ABR works by detecting a user's bandwidth and CPU capacity in real time, adjusting video stream quality accordingly. When you stream our live events, you'll experience the highest quality content delivery when adaptive bitrate streaming is used because playback conditions are automatically adapted for delivering the best quality live streams.
