  1. Commission Supérieure Technique de l’Image et du Son Interoperability and Security Architecture for Digital Cinema Plate forme de test pour l’interopérabilité du Cinéma Numérique www.isa-dcinema.org With the support of Matthieu Sintas / Thierry Delpit

  2. Under the leadership of the Commission Supérieure Technique de l’Image et du Son (CST), the French technical authority for the movie industry, eight companies join forces to build a complete digital cinema distribution platform compliant with DCI specifications and SMPTE standards.

  3. ECLAIR DIGITAL CINEMA

  4. An open platform • ISA testing is run by CST. It’s open to any laboratory or distributor who would like to validate the DCI/SMPTE compliance of their D-Cinema mastering process, as well as to any manufacturer who would like to test the compatibility and performance of their equipment before a commercial release. • CST will guarantee the confidentiality of the test results.

  5. The partners of ISA • CN films works with distributors to test the digitization process on current releases, including the possibility of a demonstration in I Diff (Cannes, January 2006). • CST develops the software for the creation of DCDM and conduct tests with manufacturers and laboratories. CST is also responsible for the overall coordination of the ISA test platform.

  6. The partners of ISA • Doremi provides the play-back server compliant with DCI specifications and the hardware for JPEG 2000 compression. Doremi will also work towards integrating some of Nextamp forensic tracking into the JPEG2000 player. • Éclair Digital Cinema provides feedback from theater owners, design test procedures, and act as the liaison with DCI and SMPTE DC28.

  7. The partners of ISA • Nextamp works on forensic tracking based on video watermarking. • Open Cube provides MXF tools adapted to DCI specifications. ISA

  8. The partners of ISA • SmartJog will integrate the developments of OpenCube (MXF), Thomson (encryption and key management) and Nextamp (forensic mark) for the transport of DCP. • Thomson will participate in the test exchange of files between Technicolor (Burbank) and CST, and will develop the encryption software and key management in France.

  9. Creation of the DCPs • Creation of the DCDM • Colorimetric conversion • Resizing • MXF packaging • Creation of the DCP • JPEG 2000 compression • Encryption of the data

  12. Conclusion • CST develops tools adapted for the expertise of digital distribution techniques. • The ISA test platform is open to all distributor, post production house that want to experiment the uses of digital distribution (transport, key management, versioning,…).
