The standards have been set. The 3d-enabled blu-ray player is just able to shoot out two images in full HD through the HDMI output. Think of it as full HD "48p, 50p or 60p". The player attaches a label to each view to let the display device know the image stream is stereoscopic and which image is right and which is left. Blu-ray was always able to carry multiple image (and sound) streams at the same time. The only (significant) difference now is that the player is capable of decompressing/outputting two streams "at once".
It goes like this:
-The blu ray player reads the disc and it sees that it has two video streams and several audio/subtitles streams. It reads some labels on it that say that two streams are "stereoscopic pairs".
-The player then queries the display device over HDMI to see if it is 3D enabled. If the display replies it is, then it proceeds to decode both stream "at the same time" and ouput "double the frame rate" on the HDMI output. If the display doesn't respond to the 3D query, the player assumes it's 2D-only TV and ouputs only one of the video streams, making it just like a regular 2D movie and fully compatible with older TV's.
The display device then does whatever it wants to it to display the video image(s) it received in 3D.
Some display devices will "flicker" each FRAME (not field) in quick succession and use shutter glasses to filter them out. Call them frame sequential if you want. The majority of manufacturers are going this way.
Some other displays have a polarizer rotator in front of the screen. Some have it "active" covering the whole screen (think of it as a giant RealD zcreen), some have it passively covering every-other line of the TV. The first one "flickers" the image in time ... call it time-sequential-passive glasses system, if you want.
The other presents both images at the precise same time, but using different pixels (call it line-sequential if you want). These, the way it stands now, halve the horizontal resolution (but they could be manufactured with twice the normal 2D resolution to begin with).
Yet another display uses an active polarizer rotator on each pixel. Call it "vectographic" display, if you want. It mantains the same resolution in 2D and 3D and displays both pixels at the same time in the same space.
Etc, etc.
In other words, the blu-ray doesn't specify HOW the display is going to show the 3D. It just makes sure that, if the display is 3D "aware" (i.e. follows HDMI 1.4 specs), it can receive the image pair from the disc and do whatever it needs to do with them to show the 3D.
The first "real 3d" blu-ray players are expected soon, probably for the summer. Somebody will of course make sure a movie or two are available for the launch (i.e. Sony's Rain w/Meatballs and Aliens vs Monsters are announced). By years' end, there will be at least a handful of players and discs.
About the same thing with TV's. The first "fully compliant" (read HDMI 1.4) models will hit the streets any time now. By year's end, there will be plenty, as the TV's themselves need very little modification to become "frame sequential 3D" sets from what they already are today at the stores.
Be careful as the 3D blu-ray discs available so far are anaglyphic (= red/blue glasses crap ![[puke]](graemlins/puke.gif) ).

Sony's press release:
quote:
SAN DIEGO, CA, Feb. 10, 2010 – Continuing to drive innovation, Sony® today launched the new BDP-S470 stand-alone Blu-ray 3D™-ready player. The model can be upgraded to play Blu-ray 3D content with a firmware update available this summer.
The company also announced that the previously introduced BDP-S570 Blu-ray Disc™ model and the BDV-E770W and BDV-E570 Blu-ray Disc home theater systems will be Blu-ray 3D capable with firmware updates available this summer.
The new models, along with the previously announced BDP-S370, are now shipping and will be available at national retailers, Sony Style®, and www.sonystyle.com next month.
“Consumer excitement for 3D is unbelievably high and Sony is poised to deliver the best possible in-home experience,” said Chris Fawcett, vice president of Sony’s Home Division. “Involved in every facet of the 3D chain from professional equipment to content production and hardware, Sony is the one company that can lean on its broad expertise to deliver 3D to the home that truly captures consumer imagination.”
In addition to Blu-ray 3D playback, when connected to a broadband Internet network, all of the new models instantly stream movies, videos, music, and more from Netflix®, Amazon Video On Demand, YouTube™, Slacker® Internet Radio, Pandora® (Coming Spring 2010), NPR, Sony Pictures, Sony Music, and over 25 total providers through the Sony BRAVIA® Internet Video platform.
The new models also feature Sony’s Entertainment Database Browser using Gracenote™ technologies that allows users to browse details like actor and production information from a Blu-ray Disc and access related content found on BRAVIA Internet Video content.
Unique to the new models, users with an iPhone® or iPod® touch device can control the players using a free app called “BD Remote” that can be downloaded from the Apple App store. The app allows an iPhone or iPod touch device to function as a remote control that includes the ability to access a Blu-ray Disc’s details such as jacket artwork, actor, and production information as well as search for additional video clips online.
The models also offer improved start up and disc loading performance. When the quick start feature is turned on, the start-up time is quicker and disc loading is faster than previous models. The stand-alone Blu-ray Disc players can start-up from power off in about three seconds.
The Sony Playstation 3 is also announced to receive a firmware update in the near future to allow 3D video gaming on it and, most likely, also 3D blu-ray.
Samsung is also offering a $399 3D blu-ray player model, the BD-C6900, out to stores very soon.
Also, Samsung is already manufacturing 3D capable TV's and it's just waiting for the right moment to put them in stores.
As you can see, even some older models are capable of 3D with a firmware update, as the "power" to decompress 2 HD streams has been there for a while. Same thing with TV's: if the manufacturer wanted, they could offer an update for some models that would make them 3D compatible (fat chance, though, as the only thing they want from 3D is to make you buy a new TV and, by offering it only in the top-of-the-line models at the beginning, force early adopters to buy an expensive one).
But the technology to cheaply make a TV "3D" and to make a blu-ray player "3D" has been already in the market for a couple of years, just waiting for the standarization of the delivery method, which finally happened last December and will be in stores as soon as manufacturers get their firmwares ready and movie studios make some content available to play back on them.

And this is probably the best passive-glasses flat monitor yet to be announced for commercial availability. They have it at suggested retail of $10k, but it's geared for "professional use". At least, it comes with two pair of glasses (LOL...reald glasses work just as well). Still surprised they haven't announced a larger model with double the vertical resolution or even a 4K one now that ASICS to upscale 2K content to 4K with *INCREDIBLE* results are out in the wild.
Anyway, the home-theatre front doesn't seem to stop advancing anytime soon. Won't be long 'til we can shoot and show a 4K birthday party for the kids in our backyard.

In an expansion of its 3D production product offerings, Panasonic introduced the new BT-3DL2550, a 25.5-inch 3D LCD production monitor with full 1920 x 1200 resolution. The BT-3DL2550 provides 3D display with true-to-life color in a durable, production-tough LCD panel package.
“With professional connectivity, including dual HD-SDI and DVI interfaces, exceptional color performance and a ruggedized frame, the BT-3DL2550 provides everything a production team would need for 3D monitoring in the field,” said Joe Facchini, Vice President of Sales and Product Management. “It supports older frame compatible 3D formats and connects easily with common professional interfaces, so it can integrate into any production.”
The monitor displays 3D content using an Xpol®* polarizing filter, so content can be viewed with polarizing (passive) 3D eyeglasses. It switches from Left to Right image display, overlay, Left and Right two window display and 3D.
The BT-3DL2550 offers the same exceptional-quality color reproduction as Panasonic’s popular
BT-LH2550 LCD production monitor. With an In-Plane Switching (IPS) panel and 10-bit processing circuit, the monitor delivers full 1920 x 1200 resolution with exceptionally clear detail and offers six color settings - SMPTE, EBU, ITU-R BT.709, Adobe 2.2, Adobe 1.8 and D-Cinema – for superior color range and a three-dimensional look-up table (LUT) for calibration. It supports 1080i, 1080p and 720p playback, and offers pixel-to-pixel function in 720p mode.
The BT-3DL2550 is equipped with two HD/SD-SDI inputs for simultaneous display of Left image, Right image and 3D signals. 3D signals can also be supported line-by-line or side-by-side using the monitor’s DVI-D input. Additional professional level inputs include two HD/SD-SDI inputs, component and RGB, as well as standard RS-232C (9-pin) and GPI (9-pin) remote inputs, headphone jack, green and red tally lamps on the front panel. It also has an embedded audio decoder on board (through its headphone jack), time code display, closed caption (through video input only), audio level meter display of up to eight channels.
The 3D monitor can be connected directly to Panasonic’s Full HD 3D camcorder and other 3D cameras via HD-SDI inputs. It can also be connected to high-end NLE systems like Quantel’s IQ and Pablo via its two HD-SDI (simultaneous signal) or to a NLE system running Final Cut Pro via DVI-D (line-by-line signal).
Additional features include pre-installed calibration software, Cine-gamma Film-Rec compensation, Standard Markers and Blue-only, H/V delay display, monochrome and Cross Hatch overlay display, split-screen/freeze frame (live input vs. freeze frame),
Five customizable function keys on the front panel can be assigned with various display modes and settings for quick, one-touch adjustments.
The BT-3DL2550 has a durable, lightweight frame and aluminum alloy back panel, and it is VESA-mount compatible. It comes standard with two polarizing 3D glasses, a desk stand and an AC adapter.
The BT-3DL2550 3D production monitor will be available this September at a suggested list price $9,900.
Speaking of 4K ...

Mitsubishi’s new Upscalling technology turns your HD video into 4K2K wonders
Mitsubishi demonstrated today in Japan its new 4K2K upscaling technology for full HD content. According to Mitsubishi Electric, thanks to a new upscaling algorithm and software, they are now capable of uscaling your Full HD videos into a wonderful 4K2K one.
While this technology supports 1.4 HDMI, it is not yet capable of upscaling Blu-Ray contents.
This technology will equip future 4K2K TVs in order to help the transition between HD and this new resolution.
