DTT HD broadcasts in the UK, are dynamically switched on a GOP level
(every 12 frames) basis


GoP lengths are not fixed any more. A quick check of a couple of things
recorded a day or two ago shows them varying between about 10 and 40 frames.


Oooh. GOPs can be anything of course, though the HD channels
traditionally have been 12 frames I think (Until now it would seem!)

I do recall C5 SD having something really whacky a few years ago,
something like 60 frames (2.4 seconds !)
