What exactly is a 3D HDTV and what will it offer me?
Question by Jason G: What exactly is a 3D HDTV and what will it offer me?
I’ve been hearing a lot about this 3D HDTV and I’m very interested. But unfortunately I live in South Africa and we don’t really get the best information on these types of things here.
When will it be released in SA? Will I need glasses? How much will it cost? What will it allow me to do with my PS3?
I have a lot more questions, but any info you can give me would be much appreciated.

I don’t have release dates or cost info re SA, but very briefly, 3D gives a sense of depth to a scene, as if you were alongside the camera while the action is being filmed. It’s done by capturing separate images for each eye. The two images are isolated by means of special electronic glasses as you watch the scene on the 3D TV.
It can only be done with a very few sets currently marketed by Samsung and Panasonic, and you need the special glasses that come with them. And it only works on programming that is originated in that technology.

The cost of a 3D TV is approximately $ 3000-4000 USD for about a 55″ display.
The first 3D TVs are expected to reach SA very shortly, as early as next month, and certainly by September you will start to see competition from several major brands.
The wireless 3D Glasses are battery powered and are quite expensive at about $ 150 USD/pair, sometimes even more.
By the end of this year, or sometime next year, you will be able to play a number of PS3 games in true stereoscopic 3D (with realistic dimension and depth). It is also possible to play 3D Blu-Ray movies on your 3D TV via your PS3.
You will also be able to watch 3D broadcast TV channels if you have a compatible set-top box (this is becoming popular for various sporting events in Australia and the United States right now).
The 3d tvs will use the field sequential or frame sequential 3d format. It looks just like polarized 3d in most theaters that use tinted glasses that are passive and have no moving parts. field sequential uses shutter glasses that open and close, with one lens opening while the other one closes and they do this back and forth very fast. Then when one lens is open the image for that eye will flash on screen. This works different from polarized which all left eye images have one polarize light wave and all right eye images a second polarized light wave. Then the lenses of the glasses block the light wave for the other eye. Field sequential is used for tv because polarized has its own draw backs when used for tv although polarized 3d televisions do exist. The screen has to be made to put out two polarized light waves.
