Hi,
been thinking, perhaps someone can clarify for me about 3D tv and so on.

Couple of months ago I went to a well known store and they had a 3D tv on display with 3D glasses so you could see the 3D in effect.

Now how does a 3D tv work?

I was under the impression I could put a 3D dvd into my normal dvd player, put some 3D glasses on and sit back and watch it on my normal Panasonic Plasma tv? Which I am pretty sure you can do.

So these 3D tv's do they just change what is broadcast into 3D? and if so does that mean any of my old normal dvd's and ps3 games, would they be then viewable in 3D?

Just confuses me a little, cannot seem to understand 3D tv's, as you still have to wear the glasses, same as normal tv's whilst watching a 3D dvd

Thanks
 
all your assumptions are wrong. 3d is only available on blu-ray, standard bluray players do not support the 3d format, 3d blu rays support much higher rates video, 100 or 120hz and thats not the pretend carp tvs blag having. andso the tv must be able to accept this much higher true signal input hence why only specific models are capable.

im sure someone else can explain indepth but the short and curly of it is that standard gear just doesnt have the hardware to do the job.
 
ok Kanifee, i hear that,

but I can go out and buy for eg: final destination 3d, stick some glasses on and then watch it on my plasma in 3d ? so isnt that it ? or ?
 
im lost, i was under the impression, (or so i though), you could buy, for eg: final destination on 3d some years ago and you just watched it on a tv whilst wearing those glasses, i must be wrong then. Nee mind.

thanks guys
 
Am sure you would be able to watch it if it is in the nasty 3D way of the two colours (Red and green) ala JAWS 3D stylee.

But if it is not this, then you will need to have a new 3D tv. This is due to it showing seperate images for the left and right eyes in rapid succesion, hence the need for the fast refresh rate on the TV. The glasses are need as each image is polarised in a different way. One vertical and one horizontal. the glasses sync with the TV and only let one eye see one image at anyone time, so your brain is tricked into thinking you are viewing the scene from two seperate view points, hence 3D.

hope that helps some
 
You require a 3DTV for the latest 3D technology and a 3D Blu-Ray player to play 3D Blu-Rays.

Sky have a 3d Channel for Sky World HD customers but that's not the only way you can get 3D. If you have a media player like a PS3 or WD TV then you can still watch 3D movies such as those found online (legal sites do exist).

To complicate things there are numerous ways to get 3D

1. Anaglyf (sp?) which are those early 3D films using the red/green glasses. To be honest, I've always thought this was a bit rubbish and never got the 3D effect. That said, you don't need to buy new hardware as this type displays as a single stream meaning that any DVD/TV combination will work

2. 3D Blu-Rays. This content does require new hardware and you'll need a 3DTV, 3D BluRay player and if you want lossless HD 5.1 surround sound a new amp which has HDMI v1.4.

3D BluRays work by having the standard 2D film on the disc with an extra 'delta' file which tells the TV the differences between the two images for the left and right eye. This way you can easily get a 1080p 3D film on a 50gb bluray disc as the delta file is not as big as the actual movie itself.

PS3 is a 3D player but does not support 3D playback with HD sound as it doesn't have the required hardware. You just get standard 5.1 audio.

3. Sky & Media players inc PS3. Sky use a different method of 3D where they have both the left and right eyes running simultenously side by side. If you ever watch a 3D movie on a standard 2D TV you will see two lots of everything. 3D tvs have a button on the remote which takes the two images and overlays them giving the 3D effect. The glasses filter this out which is how you get the depth. The downside to this is that it is common practice to send the entire stream as a regular HD broadcast which is how the current HD boxes still work. That means that both images are sent at a total size of 1920x1080. Once you press the 3D button on the remote the resolution obviously drops as both images overlap. That means that usually a side by side 3D image is not full 1080p HD.

You can sometimes find 3D movies done this way which are full 1080p HD but with the overall size now 3840x1080 the size it too great so many people don't bother.
 
I'd expect the version on Final destination 3D your talking about is using anaglyph glasses Red/Cyan and not the full hd 3D version which would require a proper 3D telly.

This is correct. Both Final Destination 3D and My Bloody Valentine 3D were released on DVD/Blu-ray, but only in anaglyph red/green glasses format.

Obviously, this is a world away from the quality of current 3D technology, for which you need a 3D TV and 3D capable Blu-ray player.
