What Type of Glasses Must You Wear?
FHD3D (Full HD 3D) viewing requires a way to send the left eye image exclusively to the left eye and right eye image exclusively to the right eye. A number of ways exist to do this. To date, all FHD3D vendors have announced "shutter glasses" that blink rapidly on and off in sync with the displayed frames in the following sequence: left eye image to left eye during which time the right eyeglass lens is opaque, then right eye sequence with the left eye lens opaque, then back to the left eye and so forth. The shutters blink with sufficient rapidity to avoid the perception of flicker. An infrared or RF sync signal emitted and spread throughout the room by the 3D TV, accomplishes synchronization of the 3D frames with the glasses.
While other types of 3D glasses, including âanaglyphic,â the familiar paper ones with one red lens and one green lens (or another color combination), can and have been used in movie theaters and in other applications, because that technology does not provide the image quality or color accuracy of the shutter-type glasses it is not included in the FHD3D standard.
Commercial movie theaters showing 3D movies provide RealD 3D circular polarized glasses, linear polarization glasses, Dolby 3D glasses or Xpand shutter glasses. The Dolby glasses produce the two distinct eye views by incorporating color band filters in the lenses . The Xpand glasses are similar to the ones that will be used in home 3D systems. Xpand claims its shutter glasses produce a superior 3D presentation because they are free of the inter-ocular leakage, often referred to as âghosting,â from which other systems suffer.
Unlike glasses used in other systems, which, like everyday eyewear, are passive, Xpandâs more expensive shutter glasses are active and require a power source, typically an internal rechargeable battery. Passive glasses can be inexpensive with the circular polarization type used in RealD 3D theaters costing around a dollar each.
3D HDTVs will most likely include two sets of glasses, with additional pairs available from dealers or directly from manufacturers at a retail cost of around $75, though discount coupons and other promotions from the FHD3D makers will likely lower the cost considerably.
3D HDTVs will be sold two different ways, depending on model and vendor. "3D Ready" sets will require the additional purchase of glasses and synch emitter for viewing 3D programming. âFull 3Dâ sets will include two pairs of glasses and the infrared or RF emitter.
A number of companies say they may manufacture their own 3D glasses. Higher volume and increased competition will inevitably drive prices down on 3D shutter glasses.
Display manufacturers have yet not announced whether their respective 3D shutter glasses will be interchangeable with other TV makers units. We will have to wait until early 2010 to answer this question.

The fcc will allow hd transmission in 2010. How does one purchase a digital to analog converter box .?
nashua3200
also if you have hd tv set,how do you get your old analog recorders to work properly. d/a converter?? Will the FCC grant an extention from hd transmissions until people have a better Idea of what is envolved.
Answer
There are already digital TV broadcasts, including "HD" ones. What is happening is that after 2/17/09, almost all analog over the air broadcasts will stop.
You can buy converters for your old analog TV and recorders now, but most people are waiting until March 2008 when cheaper converters should be in the stores and the government will be sending out discount coupons that will bring the cost of the first two converters down to about $20 each.
These converters are for use with an antenna only; satellite and cable companies usually supply the conversion for their customers.
The converters only tune into on channel at a time. To change that channel you have to either use a remote control (included with converter) or press buttons on the converter box. This means that you won't be able to program your analog recorders to change the channels.
All the HDTVs I know of have analog inputs, so there isn't any problem hooking your analog recorders to them. The problem is that if you have a large screen, the picture quality will not be that great
You can also buy DVD recorders with digital (ATSC) tuners built in. I was in Walmart yesterday; they had their cheapest one down to $135. They only record in SD quality, but at least you can program them like an old VCR.
The chances of the government (FCC) changing the 2/17/09 cutoff is pretty close to zero. They are planning on getting a big pile of money by selling off some surplus channels.
The transition is to digital TV (DTV), not HDTV; some programming is not in HD. This doesn't matter if you are using a converter because they convert it all to analog with about the same quality as you get from a DVD player.
