The digital revolution is old news by now, with most people having either purchased a digital converter box or made the leap and upgraded to an actual digital set. The newest technology to attract viewers is 3D televisiona technology which actually isn’t very new at all, but dates back to the creation of stereoscopic images in the 1800s. New 3D-ready TV sets and Blu-ray players are being produced by big-name manufactures like Sony, Philips, and Panasonic, and channels are already experimenting with full-3D broadcast. But the big question is whether old televisions can once again be converted to join the 3D revolution.It’s true that there are companies offering 3D TV converters, some of which have been around since 2004. The VirtualFX 2D to 3D Television Converter (74.95 from eCrater) is one of the most popular, and promises the ability to convert a standard 2D image into full 3D with the use of its included glasses. It’s hooked up similar to a DVD player and even has four different modes depending on the video source: one for DVDs and movies, one for talk shows, one for sports, and one for music videos and theater productions.It’s difficult to find other models at this time. In early January, Mitsubishi announced a converter to make their sets Blu-ray 3D-compatible, but the company now seems to be focused on its actual 3D sets. The reason for this is that converters cannot make something 3D that isn’t already there. The boxes simply split a regular TV image in half, which looks like it’s popping out when viewed with polarized lenses. Actual 3D TVs use spectroscopy to differentiate images in the background from the characters and objects in the foreground. The latter is what appears to be coming out of the screen, and what truly makes 3D television revolutionary. It seems that if you want the full experience, you will have to pay the full price.
