For all the video nerds out there who watched the #ESC and wondered how die video encoders of the TV stations handled the demoshow level visuals of the Swedish act at the beginning of the #esc2024, here a comparison:

  1. Picture EBU feed from Malmö to the TV-Stations via DVB-S2 (1080i50 422 35mbit/s h264)
  2. Picture ARD received via DVB-T2 (1080p50 6mbit/s h265)
  3. Picture ORF1 HD received via DVB-S2 (720p50 10mbit/s h264)
  4. Picture FM4 via ORF TV-Thek (720p25 2.8mbit/s h264)

Screengrab of the Swedish performance from ARD transmitted via DVB-T2 Same frame as 1. Picture. You can see significant banding and blocking in some areas.
Screengrab of the Swedish performance from ORF1 HD transmitted via DVB-S2 Same frame as 1. Picture. You can see significant banding and blocking in some areas, not as bad as ARD.
Screengrab of the Swedish performance from ORF TV-Thek Same frame as 1. Picture. You can see really bad banding and blocking in some areas. The letters are unreadable in segments.

@HackyScientress Was 1080i50 the actual production format, or is that already a downscaled version? I would have expected the world's largest live show to be produced in 2160p50 with some kind of HDR in 2024 ...

    @tony @HackyScientress The source signal that was used for providing the German satellite signal ("Das Erste", broadcast in 720p50 because of reasons, don't get me started about that ...) was definitely 1080i. You could see the deinterlacing artifacts.
