Yesterday, Panasonic and XPand announced that they have developed M-3DI, which is intended to be a new interoperability standard for active shutter 3D glasses.
M-3DI is actually a communications protocol used to signal and sequence the glasses in step with the rapid flashing of left eye and right eye 3D images. Until now, you couldn’t use one manufacturer’s brand of active shutter glasses to view another manufacturer’s TV, due to different signaling codes. Panasonic AS glasses do work with 2010-vintage Samsung 3D TVs, but that was the exception.
This incompatibility problem was one of the reasons consumers cited for holding off on 3D TV purchases last year. It will still be an issue for Samsung TVs in 2011, as the new line employs the Bluetooth communications protocol instead of infrared linking.
XPand announced last year that they would come out with so-called “universal” active shutter glasses that could learn IR signaling codes, just like a universal TV remote control does. But this announcement takes things a step further by ensuring greater support among multiple manufacturers, including Changhong Electric Co., Ltd., FUNAI Electric Co., Ltd., Hisense Electric Co., Ltd., Hitachi Consumer Electronics Co., Ltd., Mitsubishi Electric Corporation, Seiko Epson Corporation, SIM2 Multimedia S.p.A. and ViewSonic Corporation.
What really caught my eye in the press release was this statement: “The technology will let consumers enjoy the immersive 3D experience across all types of compatible 3D displays as well as at movie theaters, with a single pair of 3D active-shutter eyewear.”
Currently, movie theaters do not use active shutter viewing systems as the cost of glasses would be prohibitive – and they’d break down pretty quickly. Apparently, Panasonic has plans to expand into that arena, possibly with their line of high-brightness digital cinema DLP projectors, but we’ve not heard any details previously.
The M-3DI standard will also cover active shutter eyewear for computer monitors and front projectors for home theater and commercial AV applications. But the big question remains: Will the other major players in active shutter 3D (Samsung and Sony) come aboard?
Rumors have abounded that Sony may add passive 3D TVs to their product line in the near future, something that will no doubt be influenced by LG’s success – or lack of it – with their new passive Cinema 3D TV line.
Regardless, this announcement is long overdue. And Samsung and Sony really ought to join the parade if only to help 3D TV sales pick up some momentum.
