I got annoyed that they kept asking if I prefer 2034 or 2044 as a switch off date
There is a much more fundamental problem that the people running the 'consultation' have seemingly failed to grasp, which is one of numeric overflow.
DVB uses Modified Julian Dates (MJD) in its EPG data and to ease calculations between DD/MM/YYYY and MJD, has certain fixed points covering 200 years (which ought to be enough for anyone, right?).
These are 1 Mar 1900 = MJD 15079 and 28 Feb 2100 = MJD 88127 (which neatly avoids the /100 & /400 leap year problems - 2000 was a leap year every 4, 2100 isn't).
When they were designing/specifying the system in 1995, they decided to use MJD and 10 Oct 1995 was already day 50000.
The real trouble is that they only allocated 16 bits for the value of the day (and effectively wasted 2 of them to start with), so the max MJD in DVB is 65535 = 22 Apr 2038, which is nowhere near the other year 2100 calculation limit.
What complete utter morons they were, having used up about 77% of the number range before they even started.
As a result all kit has this baked in to all of the software, both at the transmitting end and the receiving end.
The coding kit is not so much of a problem, as there is
relatively little of it and broadcasters are seemingly always changing coders/muxers to claim better efficiencies and ever more reductions in bit-rates for 'no change in picture quality'. This is of course largely a lie (HD now isn't like HD was 15 years ago), but that would given manufacturers an opportunity for implementing a change in the spec. somehow to accommodate later dates.
The real problem is all of the huge amount of receiving kit which will never get any updates for anything. As we know, most manufacturers give up on things 5 minutes after they stop selling whatever bit of kit, and some of them even before that.
So, basically, 22 Apr 2038 23:59:59 UTC is the end of the line, regardless of any pointless consultation by clueless muppets in so-called power. The incompetents already sealed the deal over 30 years ago. Staggering isn't it?
