The UK OTA standard is MP2 for SD and AAC for HD (partially because Dolby didn't have an Audio Description solution for TV) The BBC HD channels dynamically switch between AAC 2.0 and AAC 5.1 for surround content (and change audio bitrate too - bumping up the bitrate for 5.1 stuff)

The BBC UHD tests on DVB-T2 in 2014 (World Cup and Commonwealth Games) were AAC 2.0 too.

I don't know. I thought I read somewhere that UHD-1 DVB standards specified AC-3 for audio. I think the U.S. broadcasts are looking for AC-4. Looks like ATSC committee has recommended AC-4 over MPEG-H Audio Alliance System for ATSC 3.0
