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.
