Many generic DVB receivers also have built in teletext decoders to work around the HDMI issue.

Would be interesting to know how Sky does it in Germany (where teletext remains popular) and Italy - isn't it the same hardware as is used in the UK

SkyQ In Germany is actually completely different hardware. When Sky Germany launched UHD the accompanying box was called Sky+Pro, wich (like the older German Sky+ boxes) had a buit in Teletext decoder.

Later these Sky+Pro boxes were upgraded with a modified version of the UK SkyQ software, which removed the Teletext feature (to the annoyence of many).
