Using the DCP and Self KDM
4.3 The Menu Option ’Load KDM...’
When working on other projects on a DVS DCI Mastering system, you
may want to add parts of video or audio from already created DCPs.
While unencrypted DCP track files can be added without further ado,
for encrypted material you have to use the menu option Load KDM….
It allows you to load the keys of a self KDM into the hardware of the
DCI Mastering system. Afterwards the encrypted clips can be added to
the bin and you can use them in your project.
To use an encrypted track file in another project of the DVS software
perform the following:
 On the Project menu select the menu option Load KDM….
This will open the dialog window to open a file.
 In this window select the self KDM generated for the DCP from
which the track file should be used and confirm your selection with
the button OPEN.
A message will appear on the screen warning you that the selected
KDM is not intended for the currently opened project.
 In the message window click on the button IGNORE.
This will load the keys of the self KDM into the DCI Mastering system.
 Afterwards add the wanted track file (video, audio or subtitles) to
the bin either by using a file manager or the menu option Add
clip… of the bin’s context menu.
This will make the encrypted track file available in the DVS software
and you can use it in your project.
The self KDM must have been created for the DVS system
where you are working on (see also section “Configurations for
a Self KDM” on page 4-2).
The number of keys that can be loaded at a time is limited. A
single KDM usually contains several keys (one for each track
file) and up to 256 different keys can be loaded.
You can also work the other way around: First load the en-
crypted track file and then the self KDM.
When using this function, encrypted material may sometimes
provide no thumbnails or waveforms in the DVS software.
However, the material is decrypted and can be used as usual
(e.g. video can be seen in the overlay).
