I thought those were 14:9 sets in Europe.

I guess I was remembering that some EBU programs were produced in 14:9:
A common compromise is to shoot or create material at an aspect ratio of
14:9, and to lose some image at each side for 4:3 presentation, and some
image at top and bottom for 16:9 presentation.

The 14:9 format -sometimes known as 14:9 letterbox - is an agreed
specification of the European Broadcasting Union. This specifies that
programmes made in 16:9 must be produced in a 'shoot and protect' mode
of 14:9 to ensure that viewers using conventional 4:3 TV receivers do
not lose any essential picture information.

If you are watching analogue television on a 4:3 set, however, you will
see a picture a little smaller than you are used to, with narrow black
'letterboxing' bars above and below the picture. This image has an
aspect ratio of 14:9 and is a curiously British compromise between
widescreen and 4:3.

Currently from a broadcast point of view there are aspect ratios other
than 4:3, 16:9 and 2.35:1 being broadcast, I assume they are ment to be
the standard but there are other formats being used with smaller bands
at the top. I think some transmissions are based on 14:9 source
material. I also have the official DVD from the Avalon Airshow that
Celebrated 100 Years of Powered Flight
<http://www.geocities.com/saussie01au/avalon.html>. For some reason it
was produced in the 14:9 format...

"For some years to come it is fair to say that the majority of viewers
will see 14:9."
