DRM requires hardware support to be useful. If the Widevine software
component was solely responsible for DRM then another software
component running on the same system (e.g. in the kernel) would be
able to capture all video frames.

Please study Intel PAVP and Intel Insider. The best information I
have seen on the topic so far is Intel's ME book. Free PDF download
after registration.

Management Engine"

My irony-meter immediately went to 11 ... million.
