Send comments to Kate Murray at the Library of Congress ([email protected]). Abstract RDD 48 specifies a vendor-neutral subset of the MXF file format for the long-term archiving and preservation of moving image and other audiovisual content, including all forms of Ancillary Data, together with Associated Materials. Among other features, RDD 48 defines a means for the carriage and labeling of multiple timecodes and audio tracks; the handling of captions, subtitles, and Timed Text; a minimal core metadata set; program segmentation metadata; and embedded content integrity data. The overall Registered Disclosure Document has been written broadly, to cover a wide range of audiovisual content. One derivative or secondary related version (referred to by the former Advanced Media Workflow Association or AMWA term shim) is included via a set of constraints specified in annex J. This derivative version is named the RDD 48 Baseband Shim: Single Items from Baseband Video, and it is intended to serve the most critical current needs of many archives: the reformatting of older analog and digital videotapes and, for some organizations, the encoding and packaging of "live" video streams sent to an archive via a serial interface. Additional derivative or secondary related versions have been identified for future development including born digital (retain and rewrap essence as acquired), scanned film and other content types with RGB- and XYZ-based picture essences, and audio-only. Interest has also been expressed in some additional content types, including telemetry data, HDR imagery, and multi- and hyper-spectral imagery. The RDD 48 development project is led by the Library of Congress and other members of the Federal Agencies Digital Guidelines Initiative (FADGI). At various times, the project team included representatives of the Library, the US National Archives, EVS, Cube-Tec, AVP, the CBC, George Blood Audio/Video, and Metaglue Corporation. The core user group for RDD 48 will be archives that maintain audiovisual content for the long term. Licensed under a Creative Commons Attribution-Share Alike 4.0 International License.

Following the rules of the CC BY-SA 4.0 license for adapted material, this updated document continues with the same CC BY-SA 4.0 license as the 2016 AMWA Proposed Specification document. NOTES: The user’s attention is called to the possibility that implementation and compliance with this specification may require use of subject matter covered by patent rights.

Page 2 of 113 SMPTE RDD 48:2018 Document History This document began as the Application Specification for Archiving and Preservation (ASAP) by FADGI. The AS- 07 designation was assigned in 2012 when the specification came under AMWA auspices. Although AMWA had not yet established its Work in Progress (WIP) category, versions of AS-07 have been shared in a WIP manner with the archiving community five times and once as a Proposed Specification with peer review. The 2017 version was published under FADGI sponsorship, again with community peer review and is the last iteration to carry the AS-07 designation. Starting in 2018, the name is changed to RDD 48 and the document is published by SMPTE: • September 8, 2017 (FADGI): AS-07: MXF Archive and Preservation Format Application Specification o http://www.digitizationguidelines.gov/guidelines/AS-07_20170908.pdf • June 2016 (AMWA): AS-07 MXF Archive and Preservation Format Proposed Specification o http://www.amwa.tv/downloads/specifications/AS-07_Proposed_Application_Specification.pdf • September 2015 (AMWA): AS-07 MXF Archive and Preservation Format (draft 9/2015) o https://www.amwa.tv/downloads/as-07/AS-07_reviewDraft_20150904.pdf • September 2014 (AMWA): AS-07 MXF Archive and Preservation Format (draft 9/2014) o https://www.amwa.tv/downloads/as-07/AS-07_reviewDraft_20140923.pdf • October 2012 (FADGI): MXF Application Specification for Archiving and Preservation, version 1k o http://www.digitizationguidelines.gov/audio-visual/documents/FADGI_MXF_ASAP_1k_2012_10_05.pdf • August 2011 (FADGI): MXF Application Specification for Archiving and Preservation, version 1h o http://www.digitizationguidelines.gov/guidelines/FADGI_MXF_ASAP_Arch_Pres_1h_20110815.pdf • October 2010 (FADGI): MXF Application Specification for Archiving and Preservation, version 1d o http://www.digitizationguidelines.gov/guidelines/FADGI_MXF_ASAP_Arch_Pres_1d_cf_20101020.pdf Legacy Elements in RDD 48 The document now known as RDD 48 was developed and launched as the AS-07 Application Specification project under the AMWA process rules in effect at that time (2012-2015). The majority of the drafting work on the specification as presented in this document was completed in 2016 under a new set of AMWA process rules. This history accounts for the fact that this document retains the AS-07 identifier in some areas and includes information about the derivative version called the Baseband Shim. Some of the SMPTE ULs and other tagging elements especially the DMS Item Names established during 2014 and 2015 use "AS07" and “AS-07” in tag strings as they were created when the AS-07 designation was in in use. In addition, the Manifest XML scheme includes references to AS-07 in the target namespace. These elements and naming conventions will continue but are understood to represent RDD 48.

    MXF Application Specification for Archiving and Preservation

    AS-AP MXF Archive and Preservation DRAFT FADGI Application Specification AS-AP MXF Archive and Preservation August 15, 2011 (rev 1h) Document Status This document-in-progress is being drafted by the Audio-Visual Working Group of the Federal Agencies Digitization Guidelines Initiative (FADGI; http://www.digitizationguidelines.gov/audio-visual/). The Working Group will transmit a refined version of this MXF Application Specification for Archive and Preservation (AS-AP) for finalization and publication by the Advanced Media Workflow Association (AMWA). Finalization will also depend upon the resolution of some technical matters that are dependencies for this specification. These dependencies are highlighted in the explanatory notes within this specification and in the accompanying document Preservation Video File Format Issues and Considerations (http://www.digitizationguidelines.gov/audio-visual/documents/FADGI_MXF_ASAP_Issues_20110815.pdf). This document has been drafted in the style of other AMWA application specifications (http://www.amwa.tv/projects/application_specifications.shtml), has borrowed a number of features from AS- 03, and refers to AS-02. Since AS-02 has not been published at this writing, this document (especially Annex B) includes wording copied from draft versions of that specification. Executive Summary This document describes a vendor-neutral subset of the MXF file format to use for long-term archiving and preservation of moving image content and associated materials including audio, captions and metadata. Archive and Preservation and files (AS-AP files) may contain a single item, or an entire series of items. Various configurations of sets of AS-AP files are discussed in the Overview. AS-AP files are intended to be used in combination with external finding aids or catalog records.

Type D-11 HDCAM compressed picture data stream mapping is defined for source coded picture rates of 24/1.001/P, 24/P, 25/P, 50-I, 30/1.001/P, and 60/1.001. For the transmission of compressed picture data coded at source picture rates of 25/P and 50/I, the SDTI interface operates at a frame rate of 25 Hz. For the transmission of compressed picture data coded at source picture rates of 30/1.001P and 60/1.001I, the SDTI interface operates at a frame rate of 30/1.001 Hz. The transmission of compressed picture data coded at the source picture rates of 24/1.001/P and 24/P require the SDTI interface to operate at frame rates of 24/1.001 Hz and 24 Hz with the parameters defined in normative annex A and annex B of this standard.
