When dolby gets involved usually it means ''mainstream'' .Complete control of the disc etc authoring to another dolby logo on your avr Impressive converting SBS format into frame packed on the fly perfect for bandwidth starved fta and compressed 3d bd rips

Why phillips ? Glasses free tv is the tie in... Current active shutter displays are still compatible thankfully This has implications for more than the projector forum needless to say but 3d is best when its big so posted here ..

The core component of Dolby 3D is a pixel-accurate conversion/multiview-rendering module. It’s designed to deliver the industry’s most "depth-accurate" 3D video for glasses-free (autostereoscopic) displays. Other important features of the module include:
Real-time conversion of 2D content to 3D
User control to adjust depth and perspective for any 3D display
Dolby 3D also features bandwidth-efficient frame-compatible full-resolution (FCFR) video-codec enhancement technology for all H.264 devices. This ensures full HD playback at any connection speed.

Ahh cool.  I only hope that hit the projection market as well.  Dolby 3D is the best passive solution in the cinema and it is a shame it lost out (due to the cost of the glasses) to REAL D.  Unless they have had a re-think about thier 'colour wheel' the only way to use their system in the home is a twin projeection system, so here is hoping that they do release their spinning disc system.

For filmmakers, Dolby 3D Digital Cinema simplifies the process of creating and distributing 3D movies - no need for extra colour correction or other processes in postproduction

Seems to tie in with the dolby 3d encoded discs that was mentioned hopefully ? sounds compelling in any case ...

There are so many 2d ..> 3d conversion algorithms available from display to dvdfab it will be interesting to see how good the one mentioned here is as well

From what I read, these TV's have 25+ different viewing angles, and is done by having a hugely high resolution screen. This is a quad (4K) sample, so I would assume that the end result is a whole lot of 720p images? Almost need an 8K display before you can pump out 25+ 1080p images. Seems like a lot of pixels to produce 1080p 3D.

I note that the established Dolby 3D cinema projection system differentiates Left and Right by using subtly different wavelengths in the light sources. If it were attempted with a TV, you'd neded to use duplicate slightly different wavelength sets of phosphors, e.g. Red1, Red 2, Green 1, Green 2, Blue 1, Blue 2. There would be no parallax barrier: you could view from any angle. The passive glasses would allow Red wavelength 1 through to the left eye, and Red wavelength 2 through to the Right eye. Green and Blue similarly differentiated.

Displays using parallax barriers for 25+ different vewing angles have been mooted for some time, though that type of technology tends to have low horizontal resolution, to date. To overcome that, you would need at least double the usual number of pixels of a 2D display.

I see there's another 3D projector system that relies on colour filters, called Omega 3D; which utilses two projectors. There's a recent thread about it on AVS forum: Official Omega 3D passive projection system thread

This may be an embryonic development at this point, but it is interesting, Could possibly offer a low cost home theatre 3D solution for someone who already has two projectors.  I'd be wary until further details emerge...
