NASA-PDS/PDS4-CCB#19

💡 SCR Summary

Priority

Normal / Non-urgent

IM Build

1.22.0

Checked for duplicates

No - I haven't checked

Problem Statement

We passed CCB-325, Support for video and audio as product observational, but not all the docs have been updated. Looks like the Standards Reference received updates but some other docs did not. Perhaps this was a known decision. At a minimum the MP4 document here needs an update (attached): https://pds.nasa.gov/datastandards/documents/archiving/

Additional Details

No response

Applicable Components

Concepts Document, Data Providers Handbook (DPH), Standards Reference (SR)

Note:  The requested changes to the SR were implemented in Version 1.20.0 on 20230301.   No additional changes needed to the SR.

Proposed Solution

Note sure who needs to update the downloads and document sections as listed in the attached zip file.

Requested Changes

Applicable documentation:

  1. Update "PDS Policy on Formats for PDS4 Data and Documentation (https://pds.nasa.gov/datastandards/documents/policy/format_policies_final.pdf) to allow these restricted formats for compressed video and/or audio science data and documentation (see format_policies_230222-1.docx).

  2. Update the supplementary white paper (attached here, MP4-H264-ACC_v4.pdf) on use of compressed data to include video and audio science data. Include guidelines for setting Constant Quality (CRF) and audio bit rates. overwrite original found here: https://pds.nasa.gov/datastandards/documents/archiving/ . Probably best to change the title to:

MP4: Archiving Video (MP4: H.264 and AAC)

  1. Add requirements for DN tracking of encoded video and audio products, annual reporting, and assessment of format viability at least every five years (and transformation if not) to the existing policy on data integrity checking (https://pds.nasa.gov/datastandards/documents/policy/dataintegrity_checkingschedule_20080829.pdf) (see data_integrity_update_v2.docx).

4, Update PDS4 documentation (selected above under "Applicable Components"), see Docs_Updates_v2_rs.docx for changes. Looks like the Standards Reference was updated in Version 1.20.0.

Applicable Attachments

  1. The zip file contains changes to 2 MC policies and updates to the DPH and Concepts:

video_docs_update.zip

  1. The attachment below is an update to add a missing section for 3.3 in the PDS4 Concepts document. This version of the document includes a small edit noted by the CCB:

Docs_Updates_v2_rs_th_20240404_MNH_final.docx

Impact Statement

Impact: -- Concepts Document -- The requested change has minimal impact on the document. Text is being changed. -- DPH -- The requested change has minimal impact on the document. Text is being changed. -- SR -- The requested changes were previously implemented in Version 1.20.0 -- no no impact on the document.

No Impact: -- Information Model -- Standards Reference -- APG -- External Agencies -- ISO Standards -- PDS Tools -- PDS Website

Technical Assessment

The request includes changes / updates to 2 MC Policies.

The request is to update the Concepts Document and the Data Providers Handbook (DPH) to inform users that PDS4 supports certain video and audio data formats in Product_Observational. This change makes these document consistent with the approved and implemented CCB-325. This change request is reasonable.

System Impact

None
