Glossary on 3D video quality


The 3D@Home Consortium and the MPEG Industry Forum (MPEG IF) has released a new glossary of terms for providing a common language for discussing, identifying and improving the subjective quality of stereoscopic (i.e. 3D) video.  Over 235 terms are defined within this comprehensive glossary, targeted at 3D videographers and their crews, post production, and test facilities.  It is designed to facilitate their communication on the many distinctive aspects of digital production, testing, encoding and compressing, when considering three dimensions rather than just two. 

The terms were identified and defined in a joint effort by a Project Team of the 3D@Home’s Consortium’s Content Committee (ST1) and MPEG IF’s 3D Working Group, both lead by Sean McCarthy, Ph.D., from Motorola Mobility.  Dr. McCarthy notes, “As a vision scientist, I am pleased to have, in one place, a reference guide to this new terminology.  When all individuals involved in a project are referencing a similar vocabulary, then communication can be clear and unambiguous.  That shortens creation, evaluation and development cycles and avoids costly errors.’   

Rick Dean, chair of the 3D@Home Consortium and senior vice president at THX, commented, “3D@Home Consortium is pleased to add this document to its library of vital resources for its members and the industry at large.  We continue to strive to provide tools that can be utilized extensively by experts and novices alike as 3D video creation and analysis techniques develop further.  The glossary will also serve as a natural tool for reference as training materials, best practices documents, presentations, and other communication vehicles are developed.’ 

The glossary is considered a “living’ document and subsequent revisions and updates are anticipated.  Because, when working with video creation many of the terms are often more easily demonstrated visually than in written form, plans are in place to expand the written definitions with multimedia examples available online. 

The glossary is available in PDF format and can be found at, or at or by requests via email to info @ 3DatHome-dot-org.  An online, interactive and searchable glossary will be forthcoming in several months.
