The World of 3D Television
[attachment=19197]
INTRODUCTION:
“The world of television viewing will no longer be flat.” That statement could have easily been the resounding
theme for this year’s CES show. Everywhere you looked there was some form of demonstration with 3D technology.
The following document is designed to provide a fundamental understanding of 3D technology and what the future
holds for our television viewing experience.
“The ultimate goal of the viewing experience is to create the illusion of a real environment in its absence. If this goal is
fully achieved, there is no way for an observer to distinguish whether or not what he sees is real or an optical illusion.”
Written by John Watson
Let’s start with that basic statement: In essence the goal of recreation, whether for music or video, has always been
to create the illusion of reality. 3D is our reality.
“Human beings feel the 3D impression because each of the left and right eyes recognizes different images.”Yoshi Yamada
There are only two ways that a 3D experience can be delivered to a consumer at home. The first is with the use of
glasses to view a stereoscopic or holographic image. The second type of system is with no glasses. It uses an internal
lens system at each pixel point on the screen. Phillips WOWvx is the most prominent example of this technology.
3D television: a desirable reality?
For both technologies, the biggest barrier is that the only viewers able to watch anything would have to have a
specific 3D screen and available content or at the very least some processor like the ones mentioned below, in order
to convert 2D to 3D.
"Broadcasters are likely to want to push 3D only if it makes a strong business case. If you were to look at the uptake
of HD content and screens, 3D is going to require a similar overhaul to that of the DTV conversion, for both the
homeowners and with broadcasters," said Tom Morrod, senior analyst, head of TV technology at Screen Digest.
Technology is "pretty tried and tested" in 3D cinemas using projectors. "In the home, we could see projectors or
screens with a polarized display. Both of these would need two signals, the left and right eye. This technology will
always be glasses-dependent. For television broadcast, the main problems are that two signals must be sent, which
would double the amount of bandwidth required to send them."
Summary:
3D is still in its infancy, but is recognized by the major manufacturers, as the next big thing in
television. HD 3D will be the performance standard driving the category.
Step 1: Acquisition and transmission of a 3D signal must be adopted and agreed upon
Step 2: There has to be some standardized way of converting 2D information to 3D. This will allow
older content to be viewed in some sub-standard form of 3D.
Step 3: Content is on the rise. More and more studios have agreed to shoot and / or encode software
with 3D technology. Blu-Ray appears to have the leading edge and best performance capabilities.
Step 4: Most of the major manufacturers have agreed to begin implementation of 3D chipsets in their
display devices.
