But the HTML5 stuff is surely just a bolt-on - and could just as easily be bolted on to ATSC 1.0 ? That's what HbbTV did in Europe - where it was retrospectively added to both first gen and second...

Yep - though I suspect it would be easier just to IP stream a totally self-contained 2160p signal. This is how UHD is likely to get to OTA-only TVs in Europe - with services like the BBC iPlayer...

Couple of things to know.

1. All European TV broadcasts are 50Hz. US broadcasts are 59.94/60Hz. Many US TVs are 59.94/60Hz only - so even if you buy an external set-top box to receive local TV...

I wasn't aware that European countries weren't licensing codecs. Certainly I've had to buy both MPEG2 and VC-1 codecs for my Raspberry Pis in the UK. That could be because they enforce their codec...

Are all the Denon's inputs HDMI 2.0+HDCP2.2? Some AVRs have a couple of HDMI 1.4b inputs - if you connect your STB to those it shouldn't see any HDCP 2.2 support in the chain?

Interesting. The EBU have been pushing better-pixels not more-pixels for a while now. 1080p50 or 1080p59.94 with HDR makes a lot of sense on smaller screens (i.e. <55")

Germany has gone 1080p50...
