For the UK, what is used for the Freeview OTA Broadcast lineup is the TV Guide data from https://www.freeview.co.uk/ - The main issue was that the data was April 2019 data and missed out the freeview change announcements for May and June. This was addressed but there are still few errors like E4 and Home and Movies4Men+1 plus a few more
Also freeview themselves have errors in their data - eg 235 is missing
