Introduction A 3D television is a television that employs techniques of 3D presentation, such as stereoscopic capture, multi- view capture, or 2D plus depth, and a 3D display a special viewing device to project a television program into a realistic three-dimensional field. Three dimensional TV is expected to be next revolution in the TV history.

History History The stereoscope was first invented by Sir Charles Wheatstone in Stereoscopic 3D television was demonstrated for the first time on 10 August A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.

How we see 3D Basic principle tricking our dumb, binocular brain into interpreting a 2Dimage into one with depth. A key part of this process is binocular disparity. It means each eye has a slightly different viewpoint. When an object is far away, the light traveling to one eye is parallel with the light traveling to the other eye. But as an object gets closer, the lines are no longer parallel --they converge and our eyes shift to compensate.

Common 3D display technology Projecting stereoscopic image pairs to the viewer include: Passive glass: Anaglyphic 3D (with red-blue glasses) Polarization 3D (with polarized glasses) Active glass: Alternate-frame sequencing Auto stereoscopic displays (without glasses)

Viewing through glasses Two sets of images are meant to be seen by only particular eye. Hence each eye can only see one set of images, your brain interprets this to mean that both eyes are looking at the same object. That's what creates the illusion of depth.

Polarization 3D Polarized glasses Light waves of two images are projected at certain angles. Each lens only allows light to pass through that is polarized in a compatible way. It is more popular than anaglyph glasses because the polarization don't distort the color of the image. Hence it is popular in projector based display.

Architecture of 3D TV

transmission Gigabit Ethernet A transmission technology, enables super net to deliver enhanced network performance.

Application of 3D TV  video games  TV  applications for physicists, scientists, and engineers could also be extremely useful.  Richer,Lifelike and entertaining experience than 2D TV for home users.  Future use in mobile.
