AIUI there are various feeds available via the EBU from the host broadcaster, but most will take an HD feed, clean of commentary but with the Country identifier DOG (saying who's performing, usually bottom left) and clean straps with the song number and a big gap for the broadcasters to insert their own phone number, sms number, cost details etc. This feed is a complete programme, starting at 1900gmt/utc with the Eurovision Logo and ending whenever it ends (again with the Eurovision logo.)
This feed contains several (three?) opt points of fixed lengths for broadcasters who wish to insert commercial breaks, but those breaks are filled by the host broadcaster, often with green room, for broadcasters who don't show commercials during programmes. At the host country, most broadcasters send commentators, some more than one, for different languages, TV and radio etc. Those signals are fed back to the broadcasters via isdn or quality VoIP links. In the host countries themselves, there is another gallery which mixes the commentary with the clean contest feed and adds locally relevant captions. This may be a TV gallery, or might all be done in the presentation gallery/mcr where the ads are also inserted. It depends on the complexity of what needs to be done and the facilities (and budget) the broadcaster has at their disposal.
There may be some broadcasters who send a small video production team and presenters to the contest and provide their own filler material during commercial breaks (like the bbc does for bbc three semi finals). This is fed back to the broadcasting country by a separate satellite link and mixed into the local feed.
I'm not fully across what happens with the voting contributions where spokespersons from each country call in their results. I imagine there are several links to the host broadcaster which are switched in sequence between each participating EBU country... I'd have thought there would be backup phone links just in case, but can't recall one ever being used since I'm vision voting began in the mid 90s.
