Is there a way to use DRM on HTML5 video?

Question

Since Flash is losing ground I would like to know if there are ways to protect html5 videos with DRM (H264, .ogg and WebM).

Answer 1

You could implement some kind of encryption scheme with public/private key - I recently heard about http://www.widevine.com/ who seem to be doing something like that for html5 and h.264 . But I am not aware of anyone having applied to web video in general.
