From a transmission tech perspective, how do +1 channels work?
Presumably most of the time they are literally a box which takes the live feed of the normal channel, delays it by 3600 seconds, and spits it back out for tx with a different DOG?
However does the broadcaster have the ability to break into this process, either at the box side or the tx side, with different content? I have seen before where, for rights reasons, the +1 has had to be blocked. Is this done at the box or downstream from this? Could broadcasters, if they chose to, put some completely different content up instead of the blanking?
Do any +1 broadcasters have a completely separate playout chain for their +1 channels instead of this delay box, where they could put different content/adverts/trailers on the +1 version?
Are the delay boxes located at the playout side (and require a separate uplink) or the tx side?
