For those of you who have been waiting for the advent of 3D technology for television, your wait may be over. The format will soon be here. Televisions are being made that will receive and display the 3D signal, with special glasses to separate the two images for your two eyes. The two proposed presentation formats are already in use by theaters. The one was developed by IMAX and involves switching the two sides of the glasses on and off. The other is the RealD format, which uses polarization of the two lenses 90° apart (vertical for one eye, horizontal for the other, or something like that).
ESPN and Discovery Channel are both launching all-3D channels for later this year, and other networks are expected to follow. If your set is not 3D-ready, there may also be converter boxes available soon. Check your local stores. But be patient, as this is new technology, and it might not be available right away.
