So there's 2 things going on here; "satellite broadcasting" (whatever that is) and "HTML5" which is pretty straightforward….

HTML5 is the latest version of HTML, or "HyperText Markup Language." HTML is the main markup language for web pages. It's one -- of many -- markup languages that are used to make all websites. Because of it's extreme popularity and ubiquity, HTML is one of the few markup languages that is virtually universal across all major web platforms (Windows, Mac, Linux, iOS, etc etc). HTML5 in particular ha a lot of people excited because it now includes many features that were previously reserved for commercial design languages like Adobe Flash, i.e. stuff that's NOT compatible on your iPhone and iPad.

So, in essence, one of the "killer" features of HTML5 is the ability to embed live-streaming video, simply by the inclusion of the tag in the markup of the website. And because HTML is totally compatible with iOS (iPhone, iPad, etc etc) that means that you can watch live streaming video on you iPad or iPhone simply by going to a website RATHER than installing an app from the app store.

What Moonalice has done is just this. They've designed their site with HTML5 and use HTML5's video features to embed live streams of their concerts directly on to the website. Which means that you can open up Safari on your iPad, go to Moonalice's website, and watch live streaming video or previously recorded videos directly in Safari and you don't have to install anything or buy anything from the App Store.

The "Satellite broadcasting" is evidently Moonalice's method of producing a live video stream of their remote concerts. They don't really go into detail on how they do that part of it but there's tons of ways. I wouldn't be surprised if they were doing the live streaming via the internet rather than an actual terrestrial satellite.

Hope this helps, let me know!!

Thanks Ryan
