Hi all,
This is a bit of a long shot but maybe someone can help.
I'm trying to help somebody make a KDM for Cineworld Glasgow Silverburn
screen 11, which appears to be a dual-projector ATMOS room.
We have the certificates for two TI ICPs and an Doremi IMB, and an example
KDM for this screen.
The IMB and ONE of the ICP certs make sense, but the fingerprint of the
other trusted device in the working KDM does not match the other ICP cert
(if you see what I mean).
Can anybody shed any light here? Won't the ATMOS processor (CP850?) also
require a certificate in the trusted device list?
Thanks for any insights.
Carl

I guess the CP850 cert would only needed for an ATMOS KDM - did they send you a full ATMOS
feature KDM? They should have a few I guess.
Did they comment on the exact dual screen configuration? Because, there are different dual
screen setups supported by Doremi. Doremi had a training document on these different
setups, I should be able to dig it up. Each of these variations would need a different KDM
assignment.

Yes the example KDM has ATMOS keys in it (and we're trying to make a KDM
for an ATMOS CPL).

I don't know about the configuration. I believe its one of these:
https://www.cineworld.co.uk/superscreen#/
but AFAICS the film(s) we are talking about are 2D. So maybe they just
use 2 2D projectors overlaid for more brightness or something...?

In KDMs for dual-projector setups you usually want to
– target at primary IMB
– add secondary IMB (link decryptor) as authorized device
– add primary projector as authorized device
– use formulation “Multiple Modified Transitional 1” or “DCI Specific”

Hi Wolfgang,
Thank you, that's very helpful. We got it going in the end with the
approach you suggest (I think!)
All the best,
Carl
