It says on the website above that Mitsubishi implemented their High
Resolution 3D Y/C seperation filter that's in the HLD-X9 into several
of their television sets. Did Mitsubishi ever use this technology in
their American products? I know that the recent Pioneer Elite HDTVs
supposedly used the High Resolution filters, but I'm surprised I
haven't heard anything about Mitsubishi's HDTVs. You'd think that this
9-year old technology would be more commonplace by now.

Every high-end television that I know of incorporates a 3D Y/C filter. And I'd
imagine that their more or less ALL better than the 9 year old chip in the X9.
Mitsubishi's top of the line Platinum series sets incorporate a 3D Y/C filter,
as well as 9" CRTs. They're fantastic sets, but expensive.

The comb filter in many HDTV's aren't that great. Most HDTV sets are
designed for HD and 480p content and put design consideration into
480i or analog material, so usually the comb fitlers are not top of
the line, which helps keep costs down. The current Elite and Diamond
HDTV sets use the same high resolution comb filter as in the X9. I
have an Elite 530 and it's comb filter is adjustable in a range from 1
to 5, which I believe adds in 3D processing as you turn it up. Most
HDTV's comb filters do not allow any control. The X9's filter has
three algorithims, Standard, Sports, and Art. When you select one you
can then go in and adjust the Y/C level (Normal, C-Wide, and High
Resolution), you can adjust the level of 3D processing on I believe a
10 point scale, and you can adjust the level of 3D noise reduction for
the chroma and luminance signals individually on a 10 point scale. So
even though the current Elites and the X9 have the same filter, the
X9's is much more flexible to suit different program material.

Yes, but I was speaking specifically about the Mitsubishi/Pioneer
filter that is "composed of horizontal 1-dimensional filter and
non-separable vertical-temporal 2-dimensional filter".

I wouldn't jump to conclusions, unless I had access to some technical
specifications. There appears to be two different types of 3D Y/C
filters, the conventional adaptively switched kind, and the
non-separable vertical-temporal model described in the website above.
It lists a number of Mitsubishi sets that contain the filter, but I
don't think any of them are American. The newer Pioneer Elite HDTVs
are said to have them, but they have much less adjustability than the
LD players. I'd also like some solid proof that the Pioneer Elite sets
actually contain this filter.

I agree with everything MR. Taylor said but I brought home a Mits Diamond
and returned it the next day as it looked very average when watching NTSC
material. The Pioneer I brought home the next day looked just as good in
Hi-Def but was much better with NTSC material.

Even though they both use the same Mits filter, in my experience Pioneer did
a much better job with the remainder of the electronics.

Does anyone now witch Y-C separation filter the Pioneer CLD-D925 contains
and how the quality of this filter is?

That might have to do with Pioneer's internal line doubler, which is
supposed to be real good.
