quote: Mark Gulbrandsen Sure, thats assuming that ONLY cinedigm is going to be calling with your KDM's
Actually Cindigm sends their KDMs via satellite, currently Deluxe and Technicolor use the modems. I have not heard of any conflicts with transfers, I assume they simply queue it up and it redials when busy.
quote: Mark Gulbrandsen What do you do if Sony is loading KDm's and Technicolor is trying to call to drop in your Disney KDM's?
This problem still exists with 1 line per auditorium since the studios are authorizing all KDMs in a facility.
quote: Jack Ondracek With the other costs of digital and 3D being buried under all the vague reasons why we should have already installed it, why such a debate over pocket change?
What if you are Regal - 552 location 6800 screens . . . . 1 $25 line per location is $165,000 per year wasted for less than a few minutes of KDM transfer per week - Regal can easily absorb the low bandwidth KDM transfer into their corporate WAN with no additional cost. Yes $165,000 may be pocket change in Regal's multi million dollar world, but it is still a significant number that can be brought as profit to the bottom line.
quote: There are tons of ways for the studios to be in control, so that's a bogus argument. When you deliver the content into the system, have the server go out to the net and get the damn key itself. The content can even tell the server where to go to get it. This isn't rocket science.
Tell that to the studios - I was in the room when this was brought up, the studio people didn't like the idea too much; they want to control the delivery of the KDM to the facility.
The NATO DC System Requirements document addresses a lot of these topics, but we'll see how the studios respond when certain items are pushed - it will take the large exhibitors to refuse to put modems in for modems to become a moot point.
quote: Mark Gulbrandsen There is some question by at least one server manufacturer as to if they will allow them to continue being delivered to the LMS or not.....
The "Multiplex Theatre Architecture" diagram in DCI spec 1.2 shows only 1 modem plugged into the TMS so my interpretation is 1 modem per building if there is a TMS.
