On another note, sort of related to the Presfax/Playout changes - the Trails on BBC1 still seem to be in SD, except the Oneness bumpers and a QT trail a bit earlier. Are they not making Trails in HD yet?
Trails made by the BBC Creative team (who replaced Red Bee for trail production I think) are still being played out (not sure about production) in SD.
Bumpers made by the shows themselves and delivered to playout close to transmission (or played out by the teams themselves) will be in HD. (Question Time, The One Show, Watchdog, Springwatch etc. all make their own 'on-the-day' bumpers and deliver them in HD, and they are usually played out in HD)

I’ve seen some of the same trailers on BBC World News HD and they are in HD.
Was there a delay of any sort on the analog Presfax?
Not sure what you mean by an analogue version except for sending schedules through the post
I suspect rkolsen means the first-generation version that was only ever distributed in the analogue network VBI, unlike the current version which is digital WST packets (as there is no VBI left to insert it in!) - though it may also have been distributed in the analogue network (itself carried as 140Mbs digital signals in most areas) VBI at one point.
The current 'CEEFAX-like' version (i.e. the one that uses a teletext packet distribution and teletext-style display) is definitely a newer version than the one in use in the mid-90s which was entirely monochrome and could display much larger numbers for the junction count-downs (don't think they were Teletext chunky bitmaps but they could have been). (It didn't look to use a teletext character generator for output)
And to answer the question - YES! It wasn't unusual for it not to be updated (or not to be received) and to be totally incorrect...
I’m quite sure it was all ok when my wife was on duty!!
So:
* Scrape twitter content, grab so many tweets
* Run through processor to generate a few pages with them on
* Send to right folder and the teletext app will read them the next time the carousel rolls around to that page number (remembering how teletext works, constant cycle)

That and could a region reliably know when to opt based on PresFax data and time stamp if lines of communication such as talk back failed?
The 1990s/early 2000s analogue TV version of Presfax, coming from the NTA, was essentially a static list of the events in the junction. It was monochrome, and didn't update as the junction was happening. It was ok as long as nothing changed during the junction... but was rather useless if it did (if a trail was dropped or added, etc). There was however a counter that was decoded and shown on the network feed monitors, counting you through each event in the network junction. Along with talkback, this was enough to get you through junctions.
From the late 90s the DTA (Digital Transmission Area) schedules generated an SSD (Schedule Status Display). This was much better than Presfax, was in colour and it gave you real-time info on exactly what was happening (including bus cuts on the mixer).
Presfax was shutdown along with the NTA in the early 2000s.
Then when the DTA closed, and playout moved to the Broadcast Centre, we lost the SSD and gained "new" Presfax... which is the one seen in the pictures at the start of this thread. It wasn't as good as the SSD. It would move along with the events in the junction as they happened... Unfortunately it would sometimes also do it even if the programme was overrunning and the junction hadn't actually started yet! Not terribly reliable.
The new HUD feels a lot more reliable, and even has a notes field that can be used to tell you who the network news presenter is.

Except in NI, where all locally produced trails have been HD for the past 5 years.
