eurosport tv rights started in 2018, in 2016 it was up to the single national tv to put a streaming platform in place...
nothing to say about the coverage, they had all the feeds of every single race, normally with multiple commentaries (all the events that were shown on the linear tv channels in the various countries had their commentary put on the streams, too)...
what I didn't like at all, it was the fact that the tv pictures were awful*, since they only had 25 frame per second, which makes any sport almost unwatchble to me...
the English commentary was also a disaster for 95% of the events (it was the IBC's one, not the usual Eurosport commentators)...
and the worst thing of them all, the app for apple tv 4/4K was highly unstable, I had to uninstall and reinstall that app at least twice a day...
so, the idea was amazing, the actual result was to say the least reviewable...
I hope the picture quality improves a lot by the next Olympics (right now, it's better than 2 years ago, but still a bit under par if compared to the best OTT services in the world in these terms -NHL.tv and MLB.tv), but what I think does really need to change upsidedown are the apps for connected device...some of them (amazon fire tv stick, for instance) are just impossible to be used because they just can't manage the framerate correctly and the app design is a pure mess...
*it wasn't just because of my internet broadband connection, at that time I had a 200mbps FTTC connection, which worked at max speed with all the streaming services I tried (now I'm on a gigabit FTTH true fiber connection)...
p.s. don't get scared more than necessary...I'm well known to be a very, very diffcult man to be satisfied under this technical point of view...
