What is 3D TV?

Put yourself at the heart of the drama. With a 3D TV, you can experience every bit of action at home. Forget the old, blurry, red and green 3D images - today's 3D is in super sharp high definition.

How does 3D TV work?

3D TV looks incredible, but the idea behind it is really simple. It’s actually an optical illusion, designed to trick your brain that it’s seeing 3D images on a 2D screen.

Try closing one eye while looking at an object in front of you. Now close the other eye and look at the same object. See two slightly different images? Our brain combines the two to see a 3D image of the world around us. That’s how we get our sense of depth – and that’s what 3D TV tries to recreate. The magic happens in both filming and watching.

Filming 3D TV

To recreate those two images needed for 3D TV, clever cameras record from two different angles – one for each eye. By using geometric correction (that's the techy term for putting the two images together) the technology creates a brilliantly clear 3D image.

Watching 3D TV

So why do you need the 3D specs?

When you watch a show on your 3D TV, your 3D glasses filter what you see to make sure each eye only sees the picture meant for it. Smart, eh? It's why, if you don't wear 3D glasses, a 3D picture just looks blurry. (Though it's good to know that you can still watch 2D shows on a 3D TV.)

And in case you were wondering, 3D TV is high definition (HD) TV.

Active or passive 3D?

3D TVs use either ‘active 3D’ or ‘passive 3D’ technology. The main difference between them is how the 3D glasses work.

Active glasses are more expensive because they have tiny LCD screens inside them which run on batteries. Passive 3D specs are like polarised sunglasses which block out sections of light to each eye to create the illusion of depth.

Virgin TV works with active and passive 3D TVs, so you’ll always be able to enjoy 3D in all its glory.
