@benjojo H"L"S

@benjojo I remember something similar during the DVB switchover. Digital goals were a fraction of a second behind analogue ones.

@benjojo TBH satellite was the same.

I remember the "me listening to the radio" then "family watching the TV" then "maybe neighbors following via God knows what, probably some kind of early pirate internet streaming" experience.

@benjojo (non-apple-)HLS, and especially hls.js actually have built-in support for syncing viewers, including polling the server's current time in order to not rely on the clients time being synced.
The website dev/operator is to blame for not making use of that feature
