This is where I'm confused...any explanation would be helpful.
In one hand Sony insists that you need 1.4 hdmi but in another hand they say the Playstation will work
with 1.3 hdmi.
If it (3d) can work in Play station why can't they do whatever they're doing with play station to make it work.
Some small gizmo attached to make the conversion which would cost less than replacing equipment . If not possible how about giant rebates on the new stuff to get the ball rolling more quickly.
Have they backed off from previously stating the PS3 will work with HDMI 1.3 for 3D ?
If we're talking about a new "3D" HDTV or projector, you'll need HDMI 1.4 on the display device as HDMI 1.4 is set up to "talk" back and forth with the source component and say "send me 3D because I'm a 3D display". Older 1.3 displays, even those marked "3D ready", won't be able to talk to the source components about 3D bcs all of that protocol was agreed upon just recently and built in to the HDMI 1.4 from the start.
you *can* get away with 1.3 in certain cases... here is how the exceptions appear to work:
In the case of the PS3, because its internal processing will be able to handle 3D blu-ray with a firmware upgrade and because the PS3 was designed with upgrading in mind, they have found a way to add both full 3D decoding for the blu-ray and the "3D conversation" stuff into the HDMI port even though it's technically a 1.3 chipset (basically, as far as 3D stuff goes, the PS3 will sound and act like an actual HDMI 1.4 chipset as far as the 3D conversation and signal is concerned). This is because the 3D stuff on HDMI 1.4 doesn't really require a physical difference from 1.3... same bandwidth etc. as 1.3, just new meta-data protocols. So the PS3 is a rare exception in the "1.4 rule" because as far as 3D is concerned, it can be upgraded to *act* like an HDMI 1.4 device even though it's really a 1.3 chipset. Again, this is only possible because the PS3 was designed from the ground up with radical firmware updating in mind. It's doubtful that other processors will be so lucky, and 1.3 BD players other than the PS3 won't be lucky because they lack the internal circutry necessary to perform the 3D *decoding*, even if their 1.3 chipsets could be made to handle the output, so there's stuck in 2D mode because their MPEG decoding chips are hard-wired for 2D and not designed to be upgraded.
The other big unknown is what would happen if you routed a "1.4" 3D signal (including the 3D output of the PS3 here) through an HDMI 1.3 receiver on its way to the TV or display. Chances are that if your receiver is acting as a blind switch box, it would all work as the receiver wouldn't be manipulating the signal in any real way. But if the receiver is pulling out the audio stream for sound, as would usually be the case, it may not work with preserving the 3D bcs it has to un-pack and re-pack the bitstreams and might not know how to repack the 3D on its way back to your 3D TV.
So whether 1.3 receivers work with HDMI 1.4 3D signals will be a case-by-case issue that we won't know until we try.
That's the way it's looking so far based on what we've been told...
