This document provides an overview of 3D television (3DTV) technology. It discusses the key components of 3DTV systems including capture, representation, coding, transmission, signal processing, and display. Under capture, it mentions techniques like multi-camera, single camera, and holographic capture. It also addresses representation formats, coding standards, transmission methods, signal processing challenges, and various display technologies. Finally, it outlines several applications for 3DTV beyond entertainment, such as education, medicine, cultural preservation, and military/industrial uses.

5. Observations
 Stereoscopic 3DTV is quite an old concept
 Almost as old as its 2D counterpart
 2D has flourished
 3D “failed” to be popular
 Stereoscopic 3D is simpler
 Based on human visual system and
perception
 Usually creates “mismatches” of various
3D cues
 Current research on stereoscopic
3DTV is mostly targeted to overcome
such problems

6. An Overview of Candidate 3DTV
Techniques
 Stereoscopic 3DTV
 Simplest, based on “perception”
 Viewer discomfort
 Autostereoscopic
 Head-tracking stereoscopic
 Holographic 3DTV
 Basic principle -1948, first holograms – 1960
 Based on physics : duplication of light field
 Digital holographic techniques
 Holographic cameras
 Experimental holographic motion pictures – 1989
 Still at basic reseach phase

7. Integral Imaging Based 3DTV
A principle known since 1908
Based on “capturing a scene from different angles”
And then reverse projection from corresponding angles
Lenslet arrays
Variants can be classified under “holographic
techniques”
