Home 3-D: Better than in the cinema?
Monday, January 11th, 2010by Brent Butterworth
December saw what may be the two most significant events in the history of 3-D video. On December 17, the Blu-ray Disc Association announced the finalization of the Blu-ray 3-D standard. The following day marked the release of Avatar, which will be as important to 3-D as the Magna Carta was to the rule of law and Gilligan’s Island was to the modern sitcom.
Based on what I’ve heard, read, and watched, the 3-D we see in the home might just beat out what we see in the theater.
The standard released by the Blu-ray Disc Association requires the use of a new 3-D Blu-ray player (or a Sony Playstation 3) and a 3-D TV. It will pass on the new HDMI version 1.4 interface, so no special cabling will be required. Standard 2-D Blu-rays and DVDs will play on a 3-D player, and 3-D Blu-rays can be backward-compatible with existing 2-D Blu-ray players. Discs can carry 3-D video in full 1080p resolution.
While few specifics of the new standard have been made available to the public, manufacturers tell me that the new 3-D TVs will require that viewers wear LCD “shutter glasses. When the TV is showing the left-eye image, the left LCD shutter becomes transparent and the right shutter becomes opaque. The opposite happens for the right-eye image.
These shutter glasses may be a little clunky, and they probably won’t look terribly cool, and they’ll probably cost $100 or so to replace if you accidentally sit on them. However, they may have an advantage over the polarized glasses you need to watch Avatar, Up, and other 3-D releases in the movie theater.
When watching Avatar, I noticed that if I turned my head slightly, the sides of the image went out of alignment, as if I were looking at it with my eyes out of focus. I had to be careful to stare almost straight at the screen if I wanted the whole image in focus. LCD shutter glasses shouldn’t suffer this problem. While LCDs don’t perform the same at all angles, they shouldn’t produce the blurred images that I saw during Avatar.
The CES show in January promises lots and lots of new 3-D TVs and Blu-ray players—and lots of really impressive demos—so we’ll soon have a better idea of what the new home 3-D video technology offers us. Actual products should be available sometime around summer of 2010 … just in time for the Blu-ray release of Avatar.
