Channel List Management (HD and SD swapping).

Channel List Management (CLM) would actually be quite beneficial for a Freeview-IPTV platform as it actually supports non-red button IP channels, and also an IP fallback, mostly there for viewers without an aerial, or who are served by a relay transmitter and are missing the likes of Dave, Sky Arts and Drama. This also might be crucial if or when DTT loses its frequencies.

Alas, this only works with Freeview Play televisions and set-top-boxes made from 2020 onwards. (In fact last I checked the IP/IP fallback idea was included in the CLM spec, but hadn't been utilised yet) Isn't Freeview Play practically the same as YouView? Standard DTT but also integrates with internet/VOD services?
