ISA Matthieu Sintas / Thierry Delpit 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.

ISA Matthieu Sintas / Thierry Delpit 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.

ISA Matthieu Sintas / Thierry Delpit 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. The partners of ISA

ISA Matthieu Sintas / Thierry Delpit Nextamp works on forensic tracking based on video watermarking. Open Cube provides MXF tools adapted to DCI specifications. The partners of ISA ISA

Matthieu Sintas / Thierry Delpit 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. The partners of ISA

ISA Matthieu Sintas / Thierry Delpit 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,…).
