The subtitles depicted dialogue from the PBS children’s TV show Dinosaur Train.
The head of the channel’s subtitle department, Anna Zetterson, smells a rat (or is it a dinosaur?), it seems. It turns out that on some older television models you can swap out the “teletext” page from another channel while keeping the current image. On Facebook she wrote in Swedish, “On some older TVs can still choose the old teletext page for the different channels’ subtitles, while checking on a different channel. So SVT, or any operator, didn’t send these out. But it is something you can amuse yourself with on an older television set.”
We don’t care. Maybe nobody made a mixup and it was all a plot to tickle our brains. All we can say is, mission accomplished!
