> Requirements: Live streaming uses Apple’s HTTP Live Streaming (HLS) technology. HLS requires an iPhone, iPad, or iPod touch with Safari on iOS 7.0 or later, a Mac with Safari 6.0.5 or later on OS X v10.8.5 or later, or a PC with Microsoft Edge on Windows 10.

So this event is only intended for people who already are Apple customers? MS Edge as the only other way seems very weird.

How common is this HLS thing, what would be the more open alternative and what advantages do they believe HLS has over it?
