I know earlier in the thread it was said that live broadcasts will almost always have standby programmes just in case they conclude earlier, get postponed or fall of air.
In light of the Jeremy Kyle situation, and more specifically STV getting an announcement out stating in a change ot the schedule Real Deal was airing I wonder if there is some kind of alternative schedule for all programmes - or at least a small number of programmes (i.e. Coast) which they'd put out, with associated pre-recorded announcements, at short notice. Real Deal is a fairly safe show for daytime ITV, whilst the quiz shows I guess might have repeat episodes on standby if there is a legal reason around one of the contestants preventing a new episode airing.
