Apart from the cost of converting those 125,000 screens mentioned above to digital there is also the security issue. Just look at the current furore over Mp3's on the net and breach of copyright. No matter what sort of encryption you have some hacker or geek is going to crack it in next to no time and then it will be a free for all. As for DVD style of distribution, how easy is it to take home after work and burn your own copy, I know that I cant take a print home and print a new one, and if I could what would I do with it? Very few people have their own 35mm projectors but a hell of a lot have PC's and DVD's. On the other hand there is no comparison between watching a film in a good cinema and at home on your laptop.

Many modern laptops have more resolution than the current prototype Digital Cinema Projectors! A Dell SXGA+ TFT active matrix display has 1400 x 1050 resolution. The prototype Digital Cinema installations use chips having only 1280 x 1024 pixels.

The use of DVD is used only for sake that DVD can hold 6.5 GB of data vs 650 MB on CD. The data contained on DVD can only be played on the QU-Bit player and not on ANY other machine.

The SMPTE DC28 Committee has a Study Group specifically assigned to this: DC28.04 Conditional Access / Encryption.

The SMPTE web site has a request for technology that might be used for compression of the data:
http://www.smpte.org/engr/dc283rft.html

SMPTE Request for Compression Technology for Digital Cinema Applications

The following request is being sent to companies known to be suppliers of compression technology. It is posted here to ensure that parties unknown to the Study
Group are not inadvertently left out of the canvass. Interested parties should reply to Mr. Cowan at the address given below.

TO: <Company Name>

The Society of Motion Picture and Television Engineers has formed a Digital Cinema Technology Committee to investigate the need for standards for the
introduction of Digital Cinema to be successful. As part of that effort, various study groups have been formed to report back on different aspects of that technology.
The DC28.3 Study Group on Compression is investigating possible encoding algorithms that might be suitable for the compression of the high-resolution images that
are required. This information will be included in a report that is being prepared for presentation to the Technology Committee later this year.

Your company has been identified as a possible supplier of compression technology. As a result, we invite you to submit a brief description of your compression
technology to be included in that report. Because this report may be published to the industry, no proprietary or confidential
information should be given in your description. Essentially the same level of detail you might provide in technical marketing collateral is appropriate.

Be advised that this information is only informational and will not be used to rate or qualify individual proposals for Digital Cinema. It is likely that the study group will
become a working group at some point in the future, and at that time decisions about standardization of a compression scheme for Digital Cinema may begin. I
encourage <Company Name> to participate in these activities.

If you need further information I may be reached at....

In looking at the flaky at best reliability of the sundry digital sound systems, red light readers, electronically controlled platters, and on and on, hell the designers of equipment for this industry can't now make a reel that will stay together, how can we believe they can make an entitrely new more complex system work day in and out. You engineer types need improve your credibility on the stuff we already have.
