3D TV next year?

What Grundig presented during the IFA consumer electronics fair in Berlin on 32-inch LCDs, which was a world first: The objects that seemed about two feet forward and stand back from the screen, did not come from a pre-produced film, but from a stereo camera, a few yards further in the live-work operation. Unlike films, which can be trimmed at the post at rest at depth remains at such Real-time applications is no scope for manual work.
To extract the 3D information needs at breakneck speed from the camera images and displayed on the display (see “How 3-D images”) are formed so that the viewer sees a liquid-dimensional image. Four companies had cooperated in order to demonstrate the entire chain of camera, image processing, 3D and television, which will bring the latest from 2007, a three-dimensional image into our living rooms.
BRIEF HISTORY: 3D approaches for television or cinema, there are many. All provide the right and left eye a slightly different image, which is interpreted by the brain as spatial information. But no method was able to prevail so far, each has specific disadvantages. Red and green (or blue) colored images for the right and left eye, for example, can be represented very easily, but who wants to reason Farbbrillen on the nose wear. Less disruptive than the color-neutral and similar light polarization glasses is felt, but can not produce the usual televisions for each eye differently polarized light.
Shutter glasses, her glasses in the bar of the images displayed on counter and dim, require from the monitors and a synchronization signal from massive fall because of the required electronics. And all of these procedures are unfavorable for eyeglass wearers.
Without glasses
Convenient for the spectators are auto stereoscopic displays, which takes place from the public, so to speak, the screen spectacles. However, they were far more suitable for workplaces where the viewer receives from a certain angle a 3DEindruck. TV viewers need more flexibility, however: Several people want from different parts of the room can see from space and not sit here quietly.
Just the screen to make possible as itX3D Technologies company in Jena, with the help of shadow masks developed (see section “The 3D display”). Philips is working on screens with lenticules. You know, this principle of holographic images showing the outward and different views.
3D FOR THE BARGAIN PRICE?
To display the 3D images on the display depth information in the data stream must be quickly translated and distributed to the appropriate screen points. Initially, this task could still carry extra receiver, then special chips in televisions. “All the leading TV manufacturers offer such devices,” expects Grevel Thomas, CEO of 3D Image Processing. “In mass production such 3D TVs are finally just about10 percent more expensive than conventional HD TVs. “In any case, the filter must be disengaged effect for establishing the 3D and conventional 2D devices to receive broadcasts.

Thanks for the post, can’t wait to see the 3D Tvs in action.
