...... because the playout system did not preserve them Or the network directors edited the schedule and deleted or did not add the PDC codes ... so we put the display in the stack to remind them!!!!

This was typical of the lack of support that play out systems/ work flow gave to PDC (and for many years DVB SI P/F )
- with a a move/change of automation the PDC codes were safe from Network Directors editing
....which was a great step forward
- which is why there are few issues with DVB accurate record which uses the same information....
But i still think Red Bee uses a stand alone system not provided by the playout manfacturer
But P/F is a lot easier than PDC... it requires less clairvoyance! (which may be why ITV companies had a issue)

Just to give you an example - one system changed its PDC current day at 1pm local not Midnight UTC....
(reason was that too much happened at midnight so they moved some to noon - but that was a bit busy...
so they moved to 1pm ... sorted out by doing things at say 1am less to go wrong then!)
another version of the same system omitted December so November had 31 more days!
(Months 0-11 not 1-12 at different parts of program but no Days<32)
