Comcast, DirecTV and Internet-based AT&T U-Verse list ESPN 3D on their programming, and these providers serve about 45 million American households. It will soon be available for Time Warner Cable customers.
The games will only be available in 3-D to people who own 3-D enabled televisions and cable boxes. After both are successfully hooked up, the viewer must wear 3-D glasses to get the full effect.
Modern 3-D technology uses polarized light beams so the viewer can see the content in color and three dimensions. The screen projects two images, each with different polarizations. Each lens on the 3-D glasses also has different polarizations for each eye, thus creating the three-dimensional effect.
