Startover is available on around 30 channels, not just BBC.
It is true that BBC channels implement this using the BBC iPlayer app.
The other channels use what you might consider a cloud copy of the Startover program.
Programs which support Startover are shown in the Guide with what looks like the Catch Up symbol but it will be white, rather than greyed out, Greyed out signifies that a program will be available later in Catch Up.

Not much on TV just sitting down after dinner, ok let's watch some old NCIS on 5USA missed the start of the 1st episode but seen it before so can remember what's happening, no startover, next episode same series, can watch on startover, next episode same series, no startover. Who's controlling that cloud startover service, to me you don't have any on startover or they all are.
I don't expect you to be able to give a definitive answer but a different thought logic might help.
Thanks for your input Ernie, on those 3 episodes only the middle episode had a Startover icon and it was white, but when I had finished watching it and looked at the guide hoping to see a Startover icon on the next episode the Startover icon had gone from the episode I had just watched.
At least I can now watch the Euro's and forget about Startover.
Sorry if someone has already posted this but on the TV guide if the programme you want has a circular arrow symbol after it, when you click on the programme you are given the option to watch live or watch from start, hope this helps
