That's NOT what it's about!  Analogue TV is quite bandwidth-hungry
(though with proper, effective and intelligent frequency planning, the
UHF TV band could be a quarter of its present size).  Analogue TV
transmitters are also very power hungry.

The move to digital TV allows introduction of many more broadcast
channels, in smaller bandwidth, with reduced power transmitters.  The
degradation of picture quality is supposed to be so insignificant that
"the viewing public won't notice", which is obviously untrue to anyone
with normal eyesight!  The broadcasters are hoping that they'll get away
with it because of the wide adoption of the abysmal LCD and other flat
screen technologies.

The object is really to free up huge areas of UHF frequencies that can
be sold off to bale out the Exchequer again!
