RP xxxx - Measurement Methods for Resolution Characteristics of Camera Systems
To facilitate the maintenance and operation of studio equipment, the purpose of this project is to
document measurement methods for the spatial resolution characteristics of camera systems.
Specifically, to measure the Modulation Transfer Function (MTF).
New document Drafting ProjectStatus: The project was approved 2019-09-24. The work will be based on ARIB 8-TR-B41v2_0-E1. The
proponents have a Working Draft to bring to group. The group will schedule a meeting to review thedraft in early May 2020.
SMPTE 2080 Document Suite: Reference Display and Environment for Critical Viewing of Television

Status: The group has not made progress in the last quarter, but meetings will restart soon.
Part 4 passed FCD reballot 2019-01-11 with 73 comments to resolve, many of which are now
resolved. Comment resolution is ongoing.
The Part 2 revision work will restart when Part 4 has completed pre-DP-vote review.
It has been identified that Part 1 will also need revision in the light of the Part 4 work.
Business Impact: Users and industry will have common standards to assess image quality on a reference
display.
ST 2122 - Academy Spectral Similarity Index (SSI)
This new project has been initiated to standardize SSI.
Existing color-rendering metrics were designed for human vision or for television cameras, not cinema
cameras. Digital cinema cameras see light differently than human vision (and each other), so no metricto evaluate lighting based on a single set of spectral sensitivities will work for any camera. The problem isexacerbated by non-Planckian light sources such as LED; existing metrics are unreliable predictors of thecolor-rendering capability of LED lighting in cinema production.
New Standard DG ProjectStatus: A DP vote was underway at the time of the meeting, closing the end of that day. The votepassed with no comments.
ST 2094-40 – Dynamic Metadata for Color Volume Transform — Application #4
Revision addresses these issues discovered in current published document:- Two length specifications (DistributionMaxRGB, BezierCurveAnchors), two range specification(DistributionMaxRGB, KneePoint), one recommendation (DistributionMaxRGB), do not match actual
implementations.
- One metadata item (FractionBrightPixels) is optional.
Revision Drafting ProjectStatus: A DP vote was underway at the time of the meeting, closing the end of that day. The votepassed with 2 comments.
ST 2065 - ACES suite
A revision of ST 2065-1, ST 2065-2 and ST 2065-3 is necessary to address issues reported since
publication and to prepare the documents for ISO submission. This project describes the overall work
effort and sets forth the basis on which a single DG will work on the documents. There will also project torevise Parts 4 and 5 in the File Systems TC. Bug and issue tracking for all 3 documents is in place on
GitHub.

Revision Drafting Project
RP 2093 - Television Lighting Consistency Index (TLCI)The project scope is to document “Television Lighting Consistency Index (TLCI)” and “Television Lighting
Matching Factor (TLMF)”. The introduction of light emitting diode (LED) technologies is leading tounintended and possibly expensive consequences, including poor color matching between different lightsources, and very hard-to-correct color reproduction. There is currently no standard method to quantify
the quality of lighting in relation to color reproduction for television.
New document DG ProjectStatus: A DP vote was underway at the time of the meeting, closing the end of that day. The votepassed with no comments.

Business Impact of all VC-2 projects: Interoperability between systems

Digital Cinema Technology Committee (21 DC) Chaired by Steve Llamb and Jack Watts
The application of the general scope as it applies to application of mastered essence to theatrical digital
distribution, including compression, encryption, wrapping, marking, packaging, media, logging, playout,
projection, reproduction, and related topics.
Stereoscopic Subtitle / Timed Text related projects
ST 429-2 - Digital Cinema Packaging - DCP Operational Constraints
This revision addresses issues that arose during an earlier ST 428-7 revision and the development of ST
429-16.
Revision Drafting ProjectStatus: This document revision is in the publication queue. Note that there is other current work on
additional frame rates that further amends ST 429-2, and will need integration.
ST 428-7 - D-Cinema Distribution Master (DCDM) - Subtitle
Project Scope: To revise ST 428-7 to improve rendering of Japanese timed text subtitles. The standard
normatively references ISO/IEC 10646-1, which defines font files. These files provide the information toproperly render horizontal and vertical text. However, current cinema subtitle rendering
implementations do not use the vertical metrics and other features of the font file resulting in improper
vertical and horizontal positioning of Japanese characters within a vertical string.
Revision Drafting ProjectStatus: Some work-around rules have been developed to allow authors to improve rendering
consistency when font file metrics are not used.
Business Impact of Subtitles projects: Compatibility and Interoperability

Additional Digital Cinema Frame Rates

documents 428-1 and 428-2 (DCDM) and 429-2 (DCP), add HFR to DCP.
Revisions WG project
ST 428-1 - D-Cinema Distribution Master (DCDM) - Image Characteristics
Revision Drafting ProjectStatus: This document is published.
ST 429-2 - D-Cinema Packaging - DCP Operational Constraints
Amendment Drafting ProjectStatus: ST 429-2 amendment was published 2019-01. However, a problem with its normativereference to ST 429-4 was identified at the 2019-06 meeting and the publication was removed fromthe store. The way forward was complicated by the fact that other revision work on ST 429-2 forstereoscopic subtitles was underway. It was decided to take that work through to publication and tobase this amendment on that version. This amendment has reverted to FCD status to correct thereference and DP ballot will follow shortly.

Revision DG ProjectStatus: This revision has been published and this project will be closed. It has been noted that two
small editorial corrections need to be made to the published version.
The follow-on revision project, mentioned above, can now start. The revision will reflect how MXF isused in the field as well as adopt a consistent formatting for registers. The proponent outlined a
proposal to split this large document into component parts.
ST 377-4 – MXF Multichannel Audio Labeling Framework
This is a revision primarily intended to create additional MCALabelSubdescriptor properties and acontrolled vocabulary. During the development project, it was decided that the Controlled Vocabulary
would be removed and that it would be a separate document, encouraging use outside of MXF.

Working Group on Archive Exchange Format (AXF)
This Working Group (31FS-30) has defined an archive format that will promote interoperability between
all forms of archive media. Part 1 has been published for some while and deals with ‘AXF Structure andSemantics’ and includes an XML schema. A revision to the Part 1 document was published in Q2 2017. It
has been published by ISO as a Publicly Available Specification, ISO/IEC DIS 12034-1.
Business Impact: Interoperability and more cost-effective handling of technology migration issues inarchives
There are 2 current projects:
ST 2034-1 - Archive eXchange Format (AXF) — Part 1: Structure & Semantics

Project Scope: Revise ST 2034-1 to correct syntax errors in XSD file, edit text document to support XSDchanges, prepare a readme file to accompany the XSD file. It was intended to remove UML diagramsfrom the text document, but a means has been found to edit them.
Revision Drafting ProjectStatus: The text update had been complete for some while, but a requirement arose to add a“conditional any” function for extensibility that was identified in the development of Part 2. Thisfunction requires a namespace, create date/time, and update date/time version, and has thecapability to define any attribute within the namesapce.
ST 2034-2 - Archive eXchange Format (AXF) - Part 2: External Uses of XML SchemaPart 2 covers the use of AXF Structures in “Unwrapped” form, enabling aggregation of files into a“Bundle”. The schema can serve as a manifest and it can apply hierarchical structure to files. It is
intended for use from file capture on set through to archive input. There was a strong end-user demand
for this technique that gathers metadata as material passes along the workflow. Use of IMF metadata is
being considered to avoid reinvention.
New document Drafting ProjectStatus: Work is on hold until the “any” data type in Part 1 is completed.

RP xxxx - Reference Materials for DPX V2.0 HDR Implementations
This project follows hot on the heels of publishing ST 268-2 - Constrained Application of Digital MovingPicture Exchange (DPX) Format for High Dynamic Range.
Project scope: Generate a reference model and test materials that implement the essential features of
HDR DPX workflows.
New document DG ProjectStatus: The API has been rewritten in C++, the code is available on GitHub. A basic reader and writer
have been implemented. The project also includes DPX files that can be used to test reader
implementations.
Other TC-31FS businessA presentation was given by ARRI on upcoming proposed RDD projects.

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 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
TSP = Technical Specification 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.
