I stopped reading at "Content Protection"
Seriously, haven't they learned from the past? As soon as you remove DRM your sales will sky rocket. Just look at iTunes where the first DRM-free song quickly overtook a big chunk of their DRM titles. Anybody still designing DRM into their systems shows he has no idea about reality. As Wau Holland, founder of the Chaos Computer Club once put it, "Es gibt keinen Kopierschutz, nur einen Kapierschutz". (There is no copy protection, only protection from understanding)
Other than that, there always has been something called "scalable codecs" which tried to do the same as MPEG-DASH does. Essentially you have multiple streams, one basic streams, and others allowing you to have higher resolutions or more details. It's technology from the 1990s.
