Yes, this was notable during the 2012 Olympics when BBC News Channel was showing highlights of the opening ceremony until midnight and then could only show stills. 

I worked for a non-rights holder at the time and the rules were such that it wasn't worth us showing any clips at all. We had to wait until  every rights holder had shown it, which because of timezones meant by the time that had happened it was almost 24 hours later and it was old news. 

As a non-rights holder, what would be the incentive to comply with these rules? I know the government passed some laws around the Olympics so maybe in that case they were not only rules but laws.

On a more general note though, what's to stop a channel, say GB News, showing some football highlights recorded from Sky Sports without waiting for Match of the Day to be broadcast?
