Our theater will install the Digital Cinema equipment. Projector and Server.
Now, we was received the suggestion by vendor.
but, I don't know what I install among the 1.3K and 2K projector.
Our theater has screens of 110, 250, 280, 350, 500, 800 audience.

Please, show me the info.

I have always personally felt that the "1.3K" projectors had inadequate resolution for feature film presentation, regardless of the screen size --- the pixels became obvious to me even within the 2 to 4 image height distance from the screen specified by standard SMPTE 196M, and certainly objectionable for those forced to sit closer than 2 times the image height.

Here is Kodak's view:

quote:
"We are committed to doing our part to help ensure that the digital projection technology of the future matches or exceeds the best possible image quality that exhibitors can present with 35 mm equipment," says Kodak Entertainment Imaging Division President Eric Rodli. "We believe that will ultimately require higher resolution digital projectors with a capacity for faithfully reproducing the full dynamic range of nuances in colors and contrast that today's films are capable of recording."

The Kodak CineServer unveiled at the conference is designed to enable exhibitors to decrypt, decompress and send content to up to 2K resolution projectors. Rodli says that Kodak is committed to a 4K system and will provide leadership as digital projection technology continues to evolve. He also stresses that film quality sets a moving target.

If it is a NEW projector, it will most certainly be a 2K projector. TI has stopped production on the 1280 x 1024 chip set. For A/V they have moved on to the emerging 1400 x 1050 resolution and for cinema 2048 x 1080 (2K).

Current DCinema companies that are providing the real thing are Christie with their CP2000 and Barco with the DP100.

Sony? Well they trott out their 4K prototype but don't seem to be able to ship...kinda like when SDDS came out, isn't it?

What about NEC/DPI and the IS8 and IS15 2K projectors, they ar full D-cinema and in use.

John, I agree completely. I'd guess that 1.2 megapixels is the resolution of the digital projectors that Regal is using for the "Regal 20" in my area (does anyone know what Regal is using for this?). From the back of the theatre, the projected image from that looks OK, but anywhere in the front, the limited resolution is very noticeable.

I'd really like to see 4K pixels for image width become the standard for theatres before the adoption of digital projection equipment.

We used the NEC IS8 on all the media screenings of "Sin City", here in NYC. Great projector [thumbsup]

Darren, what's the resolution of that one that you have at York; assuming that it hasn't been replaced in the year or so since I saw it?

My apologies for the omission of NEC...I must admit, I lost total interest in them based on their down right childish advertisments and methods of promoting their product.

That does not take away from the fact that they are also providing DCinema solutions.

Sony won't begin to ship their 4k stuff until July. Given the yield problems they and others have had with LCOS it'll be interesting to see how they do.
