3PM EDT (if I got it right) on Tuesday, Thursday, and Saturday. Probably airing on the usual suspects on 97W Ku (RTP, RTS, TVR, BVN) although some may have it live and some may delay it to NA evening (usually BVN.)
Saturday is on Logo. I didn't check whether they're running the semifinals also, but they never did before.
I can't decide whether RTPI or RTS Sat have the better picture. BVN looks good as long as there isn't a lot of motion or flashing lights -- which rules out most of Eurovision! They just don't have enough bandwidth for that. I had hoped that the version on 97W instead of 113W would be OK since it looks sharper in normal programming, but I saw a sports report on it yesterday and it was still horrible...
Actually, 720p was originally the EBU's preferred HD format, so several EBU members chose that for their HD broadcasts. But, yes, the contest is produced in 1080i.
That must be for the finale only. The first semifinal wasn't live today on RTPI or RTS, which of course were the ones I was recording. It was on Belarus 24, and I didn't check Romania. It wasn't on the Lithuanian channel, although I'm not sure whether they usually carry it.
