Hi all,
This is interesting. It would be good to run an open database of
cinema certificates so that indies etc. can generate keys (or we can
generate keys for them). I guess the hard part is keeping the database
updated...
Yes. There are quite a few discussions now in various forums about creating encrypted DCPs
for dedicated screens/servers. On some servers, it is quite easy to download a certificate
and email it to anyone in need. On some systems, it is complicated. Not every cinema has
skilled stuff, most would probably not even know what a 'certificate' is and how
to obtain it. Some only know about equipment serial numbers.
In germany we have received more and more inquiries from new DCP and KDM issuing companies
during the last year.
It becomes obvious that a properly maintained certificate database is a trade secret and
an instrument to keep competition at distance, as all these companies are fighting for
business with the distributors while prices for DCP and KDM generation are decreasing.
A public database or automated system would change that completely. It is not clear,
however, how things like FLMx or TKR will evolve in short term. I have been to the
Motionpicturesolutions-Site recently and it seems they are also working on tools to change
booking and key retrieval. What they are trying to do is offering a content catalog where
cinemas can book content and retrieve keys automatically, upon confirmation through the
license holder. While that will probably mean some manual intervention by the studios
booking department in the beginning, it can easily be seen that at least for classic
titles this will become a fully automated video-rental-shop-type system rather sooner than
later. Other companies like Sony are working on similiar systems.
The best thing of course would be if every cinema/equipment operator would have a
certificate stored for easy access. You could even put it up on a website and simply mail
the link to any interested party.
But for now, the major issue is, if someone want's to issue an encrypted DCP, how does
he actually get the certificate for the equipment intended for screening.
Maybe this could also be something we could put up on the DCP-o-matic site as a help, like
the list of tested equipment.
E.G. the GUI of our Sony 515 allows to download the certificate to a connected computer
through the web interface. I know it's the same for Christies IMB and Doremis IMS.
Doremi has an online service and FTP site to retrieve certificates by serial number. I
know Dolby has an FTP site as well, but I think it is not open.
