6 KDM Information
In Dual IMB setups, encrypted content requires that the KDM being generated for the IMB-SM serial
number contain the certificates of both the IMB-LD and the ICP of the Primary projector in the TDL to
allow playback.
Figure 17 is a screen capture of the Doremi Labs mastering software illustrating that in the KDM
generation procedure, both the IMB serial number certificate and the ICP certificate selected require
the "Trust Any Projector" box to be unchecked.
The only KDMs that will be accepted by a Dual IMB configuration are the following:

Multiple Modified Transitional 1: KDMs for Interop or SMPTE packages

DCI Specific: for SMPTE packages only, with the DCI constraint for multiple projector
auditorium; one to one match of the TDL, AssumeTrust certificate thumbprint will be refused.
The link below will provide details and define these KDMs:

Note: The "AssumeTrust" certificate thumbprint will not work in Dual IMB configurations.
