Actually the world cup was converted from 1080i to 720P for Dutch cable
(reportedly the Samsung boxes couldn't handle 1080i too well when using AVC
compression).
The BBC has chosen 1080i for their broadcasts (including the DVB-T trial),
believe Sky eventualy chose the same, after publicly stating they would go
with 720P.
German satellite broadcasts seem to be all or mostly 1080i.
The only more regular DVB-T HD broadcasts are in France, not sure if they
are also using 1080i. Anyway there is no official EU standard/guideline.
You can see some of the 14:9 compromise on BBC Prime/(World?) as well.
16:10 is something SGI introduced to lcd's in the late nineties.
Indeed constant height 2.35:1 set-ups using two blended projectors are all
the rage at avsforum.com lately. The NTT SHR system I mentioned can also be
used for 5K by 1K, instead of 4/2K.

Hi,

No it isn't. It's 1280x720p terrestrial, and 1920x1080i on satellite
and cable (as far as I know anyway).
The only reason that 1280x768 and 1920x1200 displays exist is because
they have the same number of lines as popular computer standards.
Thus you can also display 1024x768 or 1600x1200 without any scaling.
Other than that, I think that 16:10 is stupid. 16:9 was already a
compromise between all the various aspect ratios in existence, and
now they want a compromise between the compromise and the old 4:3 ?
It's similar to the BBC broadcasting (analog terrestrial) in 14:9
(letterboxed), because the market wasn't ready for 16:9 yet. Yet.
Now they're sending full 16:9 on all digital satellite channels.
My old 30" LCD at home is also 16:10, so it makes me choose between
"16:9" and "widescreen". The former is slightly letterboxed, and the
latter is slightly distorted. Go figure.
Moving on to even wider aspect ratios...
