The Interop DCP documentation below is provided for those who seek interoperability with older digital cinema packages and equipment. Interop DCP was first created as a stopgap measure for enabling the rollout of digital cinema prior to the 2009 release of SMPTE DCP. Note that Interop KDM and Certificate documents are not presented as it is standard practice to use the SMPTE versions for all DCP types.
Important implementation details for Interop DCP can be learned by reading ISDCF’s Transitional 1, or JPEG Interop or Interop DCP (Legacy Format) document.
With the exception of the CineCanvas™ documentation, the documents below have not been maintained.  They are presented without warranty as to their fitness for a particular purpose. (Thank you TI for allowing CineCanvas to be published on this site.)
