Just received from the SIM2 mailing list. I don't think they mind me posting it here:

NO RAINBOW EFFECT and 16:9 IMAGES WITHOUT PRE-PROCESSING with the new features available on the HT 200DM DLPTM technology-base


SIM2 Multimedia, the leading manufacturer in home theatre applications, announces a new version of the HT200 DLPTM technology-based model - the HT200DM (Dual Mode) - the latest addition to the Grand Cinema series. The award-winning HT200 will also have a version with new features that will take this Grand Cinema projector to a higher level.


The new HT200DM projector - based on the new 480p DLP? component set by Texas Instruments - has been designed specifically to match the 16:9 widescreen standard. The HT200DM provides two different resolution modes (selectable by remote control):


1. the 16:9 widescreen standard with a resolution of 848 x 480 pixels - the HT200DM delivers top quality, distortion-free images without artefacts resulting from digital down-scaling.


2. the normal 4:3 video format with a resolution of 800 x600 pixels ˜ best for computer image display or traditional 4:3 video sources (VHS, etc.).


Also, the HT200DM is equipped with a new 6-segment colour wheel (instead of the 4-segment normally used) that, by increasing the frequency of the coloured images, mitigates the colour separation artefacts (also called "rainbow effect") which are visible to a small part of the population.


The colour wheel is customised to SIM2 specifications having a larger Red segment and smaller Green and Blue segments. Indeed, this new, state-of-the-art colour wheel further improves the colorimetry of the image displayed.


So if you are looking for excellent colour balance and saturation, and you have top quality video processing equipment and DVD players, the HT200DM will deliver every bit of information in those signals onto your screen. Indeed, handling clear, content-rich signals is where the HT200DM shines.


The HT200DM will be unveiled for the first time at the 2001 Home Entertainment Show (New York, 11-13 May 2001). Availability is forecasted for June 2001.


Powerful and fully compatible with a wide range of multimedia signal sources, yet very small, light and stylish, SIM2's HT200DM provides the ideal solution for users who want to have a future-ready projection system in place to meet the growing demand for 16:9 images without pre-processing.


With these new special features, SIM2 continues to raise the bar of excellence in projector performance.

Wasnt the *original* HT200 supposed to have a 6-segment color wheel? And now this post seems to suggest that (the original) has a 4-segment wheel? Whats a 4-segment wheel doing in a premium HT projector? (as opposed to a 3-segment wheel)

I am slightly confused...is there a new panel on this version of the HT200? Is it 848x600? How else would it be able to do the 848x480?


So if this is true then this means some new possibilities:


Run 848x480, throw an anamorphic lense in front of it, and have 2.35:1


Run 848x600 full panel with an anamorphic lense using Powerstrip and have 16:9 at a slightly higher res than 800x600 full panel w/ anamorphic

I don't accept #1:


"the 16:9 widescreen standard with a resolution of 848 x 480 pixels - the HT200DM delivers top quality, distortion-free images without artefacts resulting from digital down-scaling."


How can this be? It would appear to be adequate for the 480p mode of HDTV, but 1080i and 720p would both be downscaled - 1080i would require 1920X540 pixels to avoid downscaling (although 1280X540 would suffice for many sources which only use 1280 horizontal pixels) and 720p would require 1280X720 pixels.


I know it's advertizing copy, but they should not quote specifications that bely the claims being made in the same press release.

I find "rainbow visible to a small segment of the population" funny. The population doesn't seem that small based on all the posts I've read here. I hope the six segment wheel works.


I wonder if the entire panel will be addressable via HTPC. That could lead to some interesting combinations.


I wonder if they'll discontinue the standard HT200. Seems reasonable if their new product is successful.


Thanks for the post.

The original HT200 was special because it had a color wheel with an unusual small clear section (plus a true red section). I believe the term 'double frame rate' that sprang up in a HT200 discussion caused some confusion (frame rate is 30Hz - must be truely horrible to watch on a one chip DLP).

Yes - I believe all SVGA DMDs have always been 848x600. However, until now the control chips couldn't make use of it.

They don't sell it as an HDTV projector (that will come later probably). If you want to nitpick you should complain that it has to downscale 576x50Hz sources - which, ironically, is the video standard in Italy.

I agree. Taken in context with the Plus Piano announcement, it means that TI's new HT-optimized DMD driver chips are now ready. No doubt there will be more projectors using this technology.

Hello,


does anybody know if the mentioned specs for focus range ( 2.2-13.5m ) and resulting picture size ( 50-250 inches diagonal ) are for 4:3 or 16:9? My room is a little bit smaller than usual and with the present 200HT I must use an Isco. It seems that the new Ht200DM makes a bigger picture.


Thanks, Walter.

The standard HT200 will not be discontinued, the Dual Mode version is simply an addition to the Grand Cinema series.


Unfortunately the new TI component set is not available as a upgrade for existing HT200 owners.


Kind Regards
