DCI has published a revision of its Compliance Test Plan (CTP) from version 1.3.1 to version 1.3.3. CTP version 1.3.3 contains the following refinements:

  • Removes support for the following Test Subjects and corresponding test sequences:
    • Digital Cinema Server
    • Link Decryptor/Encryptor
    • Standalone D-Cinema Projector Consolidated Test Sequence
  • Clarified that the Test Subject of each Test Sequence is a single device and, accordingly, added a test sequence for a Projector designed to work with an IMB or IMBO
  • Removes support for Remote SPBs
  • Allows SSD in addition to HDD storage
  • Uses encrypted test material for Test Procedure 7.3.2 "Companion SPBs with Electronic Marriage"
  • Allow either 19 or 20 bits of location data in the FM payload

 

Importantly, CTP 1.3.3 also merges the "CTP Addendum on Testing" dated October 13, 2022, into Section 11.2 of the CTP. Readers will no longer need to refer to the separate document.

Pursuant to DCI's Compliance Test Plan Change Policy Statement, the revision of CTP 1.3.2 to CTP 1.3.3 is a Stage 1 change, taking effect immediately. See the Compliance Test Plan (CTP) page for CTP version 1.3.3.

The CTP Version 1.3.3 is available both as an online HTML edition and as a PDF file. The PDF version contains pagination and includes page numbers whereas the HTML version does not. The HTML version is considered the definitive instance of the Compliance Test Plan, Version 1.3.3. There is a redline version that compares CTP 1.3.3 to CTP 1.3.2, showing additions and deletions. The redline is available in an online HTML edition.
