Blu-ray Disc Association Announces Final 3D Specification

Based on the above, a long term universal 3D standard has to be based on a 120hz refresh capability.

hharris4, everything I have read on this topic points to that refresh rate. While many displays already operate at that or higher it is an internal operation. All video displays accept a maximum 60hz video signal, not 120hz (except for special PC monitors?). This is the reason new 3D displays will be required.

All 3D display technologies appear to be based on receiving a 1080p 120hz video signal and it was simply a matter of creating a standard. How they create the stereoscopic output from that signal is what differentiates 3D display technology and there are different methods out there. The active LCD shutter system (glasses) is easily adaptable to nearly all current display technologies and inexpensive in silicon but possibly pricey in IP royalties.

As for the PS3, I suspect it will be software upgradeable but they have not actually stated that; inferences are cheap marketing and not a public promise.

As for 3D on any display, my response on this thread is far more information than I could find elsewhere and Sony has not said a word.

I'll save my 3D prediction for the article...

Like any prediction, I could be dead wrong, especially since I have no inside information.My positive feeling toward this technology comes from announcements of multiple products that make the claim that most existing display technologies are compatible, complete with photographs of hardware that include 3D glasses and, in one case, connectors that plug into the PS3. But, I agree, that is no substitute for a solid understanding of the technology that is being proposed. I would find it strange, however, if it turned out that companies were announcing the glasses and connector hardware without any existing displays to use them with. In the worst case, it's possible that, although some sort of picture is possible with current displays, watchable 3D still has to wait for more advanced displays. I would hope that's not the case.

In any case, I stand by my opinion that once perfected, this technology will be revolutionary in many ways, some of which have yet to be imagined.

The active shutter 3D LCD glasses have been supported by Mitsubishi and Samsung for 3 years. We have not heard much because PC appears to be the only source and there is a lack of 3D content. I don't know if those displays will be compatible with the new 3D spec but suspect they are. Mits was showing 3D on their Laservuew DLP RP at CEDIA.

I think you're right. Being a Mac user, I've missed the PC announcements. However, the Mac is also getting into the game. See link below.

I'm pessimistic for the short term and optimistic for the far term. 3D smells like money right now with the success of Avatar, and everyone is staking their claim on 3D without defining what they mean by the term. This has the potential to be very bad for the consumer as well as retailers since the word "3D" is being bandied about without definition. For example you can now buy a "3D ready" TV without any definition of what that means, at least none that I can find.
