1080P displays

Richard,
Regarding your question about 1080p, I am writing an article about the
HDTV industry, one section deals with 1080p and includes SED, SXRD and
all the others, and the findings at CES 2005.
I made the effort to review the newer 70" RPTVs 1080p sets at CES,
most aligned for mid-year, Sony for Jan 05.
I saw the Sony SXRD 70" and as said to Hugh at CES I was not impressed
(and I wanted to buy that unit for me this year), even for $13000, not
anymore.
Sony first listed the set this person is asking for $10K as XBR, now
is a QUALIA for $13000, the same set (after getting into details with
Sony reps they admitted it); consumers would be paying another $3000
for the QUALIA emblem in the front.
The ones that were the best:
The DLP on TI's booth (70" made by them, but is not for sale), and
The D-ILA 70" from JVC (outstanding, for Sep 05, $9K).
Samsung and Sony have a level of quality that I would put after those
two.
SED was demo on a private reception, I do not have time for those if I
have to cover all CES Hi Def properly, I am on the run all the time to
get all the information I need, in fact I made an exception with JVC
on their typical Mandalay Bay set up out of the LVCC.
I cannot paste the material because it was not published yet, my final
is due on Tuesday.
I am including the complete version (of the one for HDTVetc) of the
1080p subject in the CES report for our mag.
People should be made aware that "some" manufacturers that do not
accept 1080p are artificially building 1080p from 1080i by taking the
two separate 540 line/fields, and each scaled to create a single 1080p
frame to make 60 of them in one second so it does not produce flicker
(in other words interpolating on a 540x1920 field another 540x 1920 of
created pixels, to complete a1080x1920 frame), The next filed the same
and so on.
We could be debating all afternoon with their R&D gurus about how
artificial and how many speed artifacts that final image would be,
rather than putting the two 540 fields together in a 1080 frame and
repeating the 1080 frame once to make 60 in a second. They do wonders
to save in the processing bandwidth than a true 1080p deinterlacer
should have to get to a cleaner 1080p.
But no one wants to talk about details of how they did it on their TV,
this is like the magic poison formulas video processing companies
never reveal.
It is also a similar disappointing feeling I had when TI disclosed how
the xHD3 chip actually works (with a chip of 1080x 960 for a 1080x1920
image), although it was a way to get to the same result I actually
wanted a chip with all the 2 million mirrors, they have it, but it is
very expensive for consumer applications yet.
The Optoma 777 for $30K 1280x720 DLP FPTV does that, it takes a
540x1920 field, scale it to a 720x1280, and shoots the next frame
built with the next 540 field on the input. Certainly it is one way
to do it but is not my cup of tea, much less for $30K.
This reminds me at the origins of line doublers for 480i.
