To watch TRUE 3D (not that Red/Green stuff), you need a 3DTV, which can be
either Plasma (e.g. Panasonic), LED LCD (e.g Samsung) or Rear Projector DLP
(e.g. Mitsubishi/ Samsung) and 3D Active Shutter Glasses (as much as $150) for
each viewer...and are NOT (yet) interchangeable between 3DTV manufacturers....
The 3DTV ("3D Ready HDTV") takes 3D formatted information via it's HDMI
interface, separates out the L and R images, and displays them alternatively
at a fairly high refresh rate (DLP does a crazy alternative L/R checkerboard
display at a much lower refresh rate). A synchronizing signal is sent (usually
via line-of-sight IR vice RF) to Active Shutter Glasses, which turns on either
the L or R eye...and your brain is presumed to put the two images together
as if you were really there....except for those 10-20% of people for whom
it simply doesn't work....or they walk away with a severe headache.....
and/or the pain is unbearable (my wife)....and sometimes an actual seizure....
Older 3D "upgradeable" DLP's also require an external, extra cost, 3D Adapter if
you are considering this presumably lower cost/lower performance alternative.
Here are the 3D threads (the 3D FAQ thread only addresses the older DLP):http://www.avsforum.com/avs-vb/forumdisplay.php?f=193
SAT and Cable systems are currently using a reduced resolution side-by-side format,
throwing away every other pixel in each line so they can fit TWO 1920x1080 images
into a single 1920x1080 frame (which will be obvious if you tune to those channels).
Since 1080 lines are still being provided, the reduction in resolution probably isn't
all that noticeable.....esp. given the difficulties is providing a 3D image that isn't
plagued with depth perception (your eyes don't know where to focus) and blurred
Blu-Ray DVRs provide TRUE HD resolution by outputting at TWICE the above data
rate via HDMI v.1.4....but the SAT/Cable boxes and their older HDMI v.1.3 interfaces
can't support this sort of thruput...hence the current down-rezzed "demo" format.
In the future, when HDMI v.1.4a interface compliant equipment is available
(perhaps a software only upgrade to current Next Gen Cable boxes & HDTVs????),
the SAT/Cable companies will finally be able to match Blu-Ray's resolutions....and
will probably also be using MPEG4 via IPTV for delivery. Until this all gets sorted
out (and low cost 3D Glasses are standardized and HDMI v.1.4a compatible AVRs are
available for passthru and/or switching), I'm advising to wait a few more months....
PS: HDMI v.1.4a is a (host software only???) upgrade to Blu-Ray's HDMI v.1.4
high data rate interface to support a variety of high & lower rez modes desired by
SAT & Cable guys....which may or may not be compatible with the new 3DTVs....
give or take a firmware update that the manufacturer's may or may not provide....
BTW: The underlying SMPTE & ISO 3D specs are STILL under development,
including how to display 3D Captions....and hence the final is not yet approved....http://3dtaskforce.com/2009/06/smpte...ec-at-nab.htmlhttp://www.smpte.org/news/pr/view?it...1234fe4d27318c
