Overview
ABSTRACT
This document describes the distribution standards of plano-stereoscopic 3DTV, either via the digital HD television broadcast networks or via the Blu-ray Disc. It then specifies the various display systems, with or without glasses. It details also the quality control of these stereoscopic pictures, detailing the potential defaults and illustrating the analysis and identification methods.

INTRODUCTION
Stereoscopy, or the technique of creating a 3D impression using binocular vision, first appeared with still images in the mid-19th century. The 1952-1954 period saw the emergence of a substantial output of stereoscopic films, which then declined, only to experience a resurgence from 2003 onwards, thanks to the use of digital techniques.
In the field of television, we had to wait until 2010 to see the emergence of 3D-s TV sets for displaying stereoscopic images, but the range of programs did not follow.
The aim of these two articles is to :
present the specificity of stereoscopy to create an impression of relief;
assess the difficulty and complexity of producing and distributing stereoscopic images for television;
understand the evolution of 3D-s TV, and its (temporary?) eclipse in favor of Ultra-High Definition TV (UHD TV).
The first article
the basic principles and parameters for creating a relief impression from two images corresponding to the two views of the left and right eyes;
the methods and tools used in 3D television production and post-production: filming, editing and 2D to 3D conversion equipment;
image formats used for storing and distributing stereoscopic images.
This article presents :
the standards used for television broadcasting of stereoscopic images, or their distribution on Blu-ray Disc ;
television display and visualization technologies ;
quality control of 3D images.
The appendix "For further information" provides references and lists a number of tools.
