Notes on this Report and the SMPTE Standards Process
All trademarks appearing herein are the property of their respective owners.
SMPTE Technology Committees (TCs) are tasked with the development and ongoing maintenance ofengineering documents concerning Television, Broadband, Film and Digital Cinema. TCs are set up by theStandards Vice President (SVP) and are overseen by the Standards Committee (ST).
The standards process operates under the SMPTE Standards Operations Manual (OM) All participants
must abide by these provisions.
Within Technology Committees, there may also be Working Groups (WGs), Study Groups (SGs) DraftingGroups (DGs) and Ad-Hoc Groups (AHGs).
The ‘Standards Community’ (SC) is a “parent group” that provides access to all Technology Committees. An
SC meeting is held during each meeting round to convey information that is relevant to all TC’s, such as
meeting logistics and registration information.
SMPTE Document Development Process
The document stages are:
WD = Working Draft CD = Committee Draft inc. pCD for public exposure FCD = Final Committee Draft
DP = Draft Publication, which initiates…… ST Audit - a due-process check by the Standards Committee
SMPTE Document-Type Abbreviations
ST = Standard
RP = Recommended Practice
EG = Engineering Guideline
RDD = Registered Disclosure Document
OV = Overview, usually used with multipart document suites to explain the structure
SMPTE Document Review
The SMPTE Operations Manual calls for review of published documents:- One Year after original publication - to check whether comments have been received during initial
implementations and to revise if required- At Five Year intervals after original publication - to check whether the provisions need to be revised
Options are: Revise; Reaffirm; Stabilize; Withdraw.
Other Notes
This report describes each active Project in each TC. Occasionally, there is more than one project group
working on a technology topic. In this case, those projects are grouped under a Topic headline.
SMPTE manages its standards documentation, meetings and ballots in an online system called OLC. It has
a Project View that includes a publicly-accessible project summary page. It is used to state the project
scope and details at the proposal stage and to track progress through to completion. In this report accessto the project view is via a link DG Project or Drafting Project if there is more than one document in a DG.
