Christopher Cookson - Warner Bros.
Cookson - The greatest value from products comes when the project enters
their library.
Cookson - Japan has a 4K by 2K display built for the home today.
Cookson - The average consumer sits 3 screen hights away from their TV
screen in their living room.
Cookson - The average viewer sits 1.5-2 screen hights away in a stadium
style theater. If the viewer has 20 20 vision, 2K is the maximum
resolution they will be capable of discerning.
Cookson - There is detail in the 4K print that is missing in the 2K. At
some future point thoes details will be important and likely visable to
the viewer with new display technologies.
Cookson - 4K maybe the theoretical limit of what lenses today will allow
capture of on 35mm film.

Behlmer - Key delivery is a slow and manual process today. As digital
cinema expands this will become a major choke. There is no analog
equivalent for key delivery in the world of film.
Behlmer - To move a film from one server to another takes almost real
time (about 2hrs). This makes moving a film from one theater to another
much more difficult than with film.
Behlmer - Key generation also takes time. When a server or projector
fails a new key must be generated for the replacement.
New Terms -
- Digital Intermediates - A digitaly scanned film file.
- DSM - Digital Source Masters are high resolution a/v files created by
a digital camera.
- DCDM - Digital Cinema Distribution Masters are the raw files packaged
in to the DCP.
- DCP - Digital Cinema Package includes the encrypted a/v files and meta
data required for "play out" in the theater. The average DCP is 150-200
GB (equevilant to 4 filled Blu-ray disks) at 2K resolution.
- DCD - Digital Cinema Delivery is the process of sending the DCP to the
theater by various methods, satalite, mailed hard drives, DVDs etc.
- Keystoning - This is the process of distorting an image from a
projector not placed even with the center line of the screen. The
process corrects the image making it rectangular instead of
trapazoidal.

JPEG2000 is the compression algorythm used. It allows for either 2K or
4K images to be extracted from the same raw data.
The Worldscreen is an EU project creating a complete Digital Cinema
workflow from backend to screen. It was a response to the US
colaboration the Digital Cinema Initiative. Partners in the Worldscreen
include among others Warner Bros., Deutch Telcom, ARRI, and Fraunhoffer.

The more formats you can transcode (dvd, mobile, theatrical, etc.), the
more revenue oportunities.
