The only bit of a video signal ABSOLUTELY guaranteed to be carried everywhere is the active picture area. Any auxilliary data can (and is) stripped by other bits of kit in the chain, and so you'd need to implement an alternate system (either separate data circuits, or some kind of watermarking system). Both of these require extra kit to be installed at all locations that would need to see the signalling - whereas at the moment an underscanned monitor is all that is required.
The BBC stopped using Cue Dots because they used them in reverse (sending signals from broadcast centres to remote contribution locations via off-air) because off-air reception had variable and significant amounts of delay in it. The ITV system (which the BBC now use at Wimbledon) where the remote contribution provider signals using cue-dots on their output has been in use continuously - though the dual dots for sponsor bumper vs ad break signals are presumably more frequent since in years gone by there was no sponsorship...

You'd think by now really they'd have a way of showing these cue dots to those who need to know about them without them being broadcast to the public. Indeed didn't cue dots disappear for a whilst about a decade ago before coming back with a vengeance?

Does anyone know how ABC in America will be scheduling their ad breaks? 45 minutes is a very, very long time to go without adverts in the US and having seen bits of the Superbowl they manage to get an ad in ever few minutes. They're not going to stick a sneaky advert in whenever someone's been injured are they?!

Oh no ITV1 HD cut away to a sponsership 3 minutes into the match & missed Gerrards goal. It looks as if the channel is now airing the SD feed.
Note: The SD feed seemed to be unaffected. Not good to convince people to watch ITV1 HD, and not good for any pubs airing it.
Is there any reason why this would have affected the HD feed only?
In relation to the above question of how ABC are handling ad breaks, hopefully better than ITV (well the HD feed anyway)

ITV1 HD just missed the England goal! Not sure if it affected everyone, but the London ITV1 HD feed on Sky went to the sponsorship ad just before the goal and then crashed into SD ITV1 after.

Once again...ITV have messed up! I'm watching on Freesat HD.......and missed the first goal. Now HD seems to have been lost on Freesat and Sky :
