This weekend I have felt sympathy for Cliff. I tried to play "Goofy Movie" for a bunch of children on the 21:9 TV. I put it in the BluRay player, whose brand name begins with a "P" and ends in a "c". For some reason it would only display with white side panels on the left and right. When I put it in the SACD/DVD player, it would fill the entire screen, and without too much visible distortion. I haven't yet figured out why this happened, I just want to admit that it is indeed annoying ! Interestingly, the aspect ratio for this movie is mentioned as 1.66:1 (that's 5:3): http://www.imdb.com/title/tt0113198/ , for the negative...

It is like when 16:9 was introduced: if you don't increase the height too much, then it won't look overwhelmingly big. 56.0" 64:27, 44.5" 16:9, and 36.3" 4:3 all have the same height (21.8"). Before this I had a 46" 16:9 RPTV, and its screen was necessarily a bit further from the wall, so I am seeing a lower screen height than before. > It does look bigger than for instance the 56" CMO panel I would not say that...

Haven't seen it for a while, it has probably been confiscated by Research. There's all kinds of neat things you can do with a quad-full-HD panel. > 4:3 content can not be made to fit on this 21:9 TV, believe it doesn't > do 1:1 mapping either of 4:3 content just 16:9 (14:9?) stretching.

But let's be clear on the terminology: normal stretching has always been there, so that 4:3 content is seen 4:3 with black side panels, and 16:9 content is seen 16:9 full-screen. Then there has always been the "movie expand" mode, where letterboxed 16:9 content in a 4:3 signal format is seen 16:9 full-screen. The 4th mode is "panorama" or "super-wide" mode, where 4:3 content is non-linearly stretched (plus a bit of vertical cropping) to be seen 16:9. The method of geometric distortion varies between TV brands, and we believe that ours is the pleasant variant. > following the demise of PAL Plus and the introduction of anamorphic > 16:9 broadcasts.

There is no good definition of "anamorphic", but I've understood it to mean that the picture is looking horizontally compressed on a 4:3 TV. (Unless you squeeze the vertical on such TV, which our CRTs could also do.) It really applies only to legacy standards (PAL, Secam, NTSC), which are targeted only at 4:3 screens. A DVD player or settop box needs to know which screen it is connected to, because it can be 4:3 or 16:9. And the screen has to know which content it is receiving, because it can be both too. This is done with the voltage on pin 8 of the Scart (12 V for 4:3, 5 V for 16:9), or with "wide screen signalling bits" in the vertical blanking interval. And these things will go wrong, of course. In that sense it is a great simplification that the (HD) output of a BluRay player is implied to always give the correct geometry on a 16:9 screen. Be grateful for small favors...

Any 2.35:1 content that is letterboxed in a 16:9 signal format can be zoomed to undistorted 21:9 full-screen. SD as well as HD. Of course, the best quality is with a movie on BluRay, then you have 3/4 * 1080 = 810 lines of vertical resolution. This is more than enough for this screen size. > I cannot zoom successfully with any anamorphic content, as far as I have > been able to determine. Not sure what you mean ? AFAIK I can not connect a PC at 2560x1080 resolution. Some modes are not possible. "Not a use case." > We need a new anamorphic option standardized, for the full 2.35:1 stretch. > And it has to be for TV transmission as well as DVDs and BluRay. Let's not include the SD standards, they should not be changed anymore. Yes, it might be nice to have a true 1920x810p or even 2560x1080p format on BluRay, and let the player add the black bars and the subtitles in the black bars for the 16:9 1080p displays. However, the added value for the viewers of 21:9 screens would be close to zero, as the picture is already superb. It's not really worth the effort to add more standards, in MY (personal) opinion. Such effort is better spent on standards for 3D. Are you aware that we have shown a 3D prototype of this screen on the IFA ? It uses a striped retarder (a.k.a. Xpol), for 540 lines per eye. It is viewed with passive polarizer goggles, same as the RealD 3D cinema. Just to show what the ultimate home cinematic experience would look like. Groeten, -- Jeroen Jeroen H.
