3-D COMES HOME

ENJOY EYE-POPPING EFFECTS WITHOUT LEAVING YOUR COUCH

The 3-D thrill that swept movie theaters last year is now headed for your living room. In the wake of a new Blu-ray standard for high definition 3-D, Panasonic, Sony and Samsung are all releasing home-theater setups that can display 3-D movies in full high-def glory. Using a combo of 3-D-capable Blu-ray players, TVs and, yes, glasses, the systems are able to deliver separate, full-screen, 1080p pictures to each eye. The technique they use creates a picture as vivid as in a movie theater without requiring a major overhaul of TV technology. And within a few years, a new cable television standard could even bring live events like the Super Bowl right to your TV in high-def 3-D.—Corinne Iozzio


THE TV
We see depth when images from our left and right eyes merge into one; to re-create that in high-def, TVs must refresh the picture at least 120 times a second with alternating frames for the left and right eye, which tricks your brain into seeing only one image. Most new TVs are fast enough to do this, but to be 3-D-capable, TVs must include a converter chip and software to break down the signal and separate the left and right images. An infrared or radio beam syncs shutter glasses [below] with the screen to produce the final 3-D effect. Sony Bravia XBR-60LX900 Price not set; sonystyle.com


THE BLU-RAY PLAYER
Blu-ray discs have plenty of room to store a separate 1080p signal for each eye (that’s twice as much information as in a 2-D movie), as well as the coding necessary to specify which image is meant for the left side and which for the right. 3-D-ready players use a special chip to interpret this info and send it to a 3-D-capable TV.

THE GLASSES
Active-shutter glasses, like those included in Panasonic’s system, rapidly block one eye at a time so that each eye sees only the frame meant for it. The glasses contain two small, black-and-clear LCD lenses that darken or lighten when a radio or infrared pulse from the TV (or an add-on emitter) signals that the image is changing.

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
