And you can back that up with what verifiable proof that 1080 lines marks
a significant increase in perceived quality to mark it out as
"proper" HD
whereas 720 lines doesn't? Why is 1080 lines "proper" HD? Why not
(taking
a semi-random number) 1440 lines?

Again, can you show me verifiable proof that the whole world should adopt
1080 lines as a hidef standard rather than 720 (or my example of 1440) or
is that just your opinion? Are you playing the "bigger number must be
better" game?

A broadcast camera will be designed to work in the highest possible format
that it would be expected to provide a feed for - if at some point it had
been decided that a further format could be (for example) 1440 lines then
you would find that broadcast cameras would be being built that could
provide source at that resolution.

I'm glad you feel that you have the perception to decide what the entire
planet should adopt (myself I would never be so bold as to make such a
statement of fact however I have my opinions).

Unfortunately even given your valuable input the agreed European standard
for high definition broadcasting is that *EITHER* 720 or 1080 lines can be
used. As part of the European standard they are *BOTH* high defintion and
therefore any display device capable of displaying a signal at either 720
or 1080 lines is just as correctly labelled as high definition as any
other.

The likelyhood is that 720p will be the predominant format (at least in
the short term) as it is the most efficient tradeoff of bandwidth
requirement and the best match with current display technology.
