I guess that most of America can't enjoy any of those 4K programs then, as there are only a handful of DOCSIS 3.1 systems in the country (at this time). Good thing that I don't have DSL either, as DSL can never be DOCSIS 3.1 compliant. And I was so looking forward to season 2 of The Man in the High Castle on Amazon.

DOCSIS has nothing at all to do with linear channels (QAM or analog). DOCSIS (1.0, 2.0, 3.0, or 3.1 is a specification concerning internet).

When fully implemented, yes a 3.1 will be required for > 2x HD. In the interim MPEG4 is accepted as I understand as a sufficient encryption method. Comcast seems IMO to be moving toward IP service, away from QAM. I guess time will tell unless someone here has heard definitively.
