There is no "standard" around DRM. Google, Microsoft and Apple each will have their own different DRM platform. If you're outside of those 3 platforms, tough luck. Their only hope is to have a popular enough 3rd party DRM platform, like from Adobe, to be able to play those videos if their OS isn't from Google, Microsoft or Apple.

How will Jolla Sailfish play these DRM'ed videos? They cannot. Unless they implement the Adobe DRM, too, which can only be implemented as a plugin, into these non-Google/Apple/MS solutions.

So now instead of just Adobe's flash , and a Silverlight that was dying anyway since Microsoft deprecated it, we'll have at least four different DRM platforms. Yay for the "HTML5 DRM"!
