Movie Theater Question best answer = 10 pts?

Question

DLP (Digital Projection) what is the diffrent in the theater? is it better than conventional film? is that like HD quality?

Answer 1

At the movie theater (at newer ones anyway), they have a different picture aspect ratio of 1.85:1 or 2.39:1 (i.e. a wider screen format) which is unmodified like any of the consumer video screens which are typically either 4:3 or 16:9.  That's the first benefit.  The second one is that their resolutions are set at an advanced high definition quality (i.e. 2K digital projectors and 4K digital projectors -which is two and four times respectively the resolution of the 1080p HDTV).  They have to be on top of their game, otherwise most people would not visit theaters anymore.  The acoustics and surround systems are superior to most home theaters as well.

Answer 2

The only thing I know about the Movie theater is the video is showing in 1080P with 24 frames per second.

Answer 3

DLP = Digital Light Processing is a digital video technology used in some rear projection TVs and some front projectors for home use. It uses tiny mirrors to reflect light that makes up the image. See the link for a more detailed explanation.

DLP chips come in resolutions up to 1920x1080 ... which is considered "full HD" (to differentiate from 1280x720, which is a lower resolution also considered HD)

If your question relates to commercial movie theatres, DLP based theatres are limited in resolution to 1920x1080 and while they can give a great image in smaller theatres they are not suitable for the really big movie screens.  For that you still need film, or Digital Cinema = 4K,  4096x2160, such as the Sony SXRD projectors ... which are starting to be installed in commercial theatres.

How does DLP compare to film?

A master 35 mm film print is capable of the equivalent of 3000+ pixel resolution (i.e. 3x DLP), BUT commercial prints distributed and shown in theatres are typically much lower resolution (equivalent of <2000 pixels), so film is not necessarily much better resolution than 1080p DLP.

The answer to your question is therefore that DLP is considered HD, but isn't quite as high resolution as film. DLP does have some advantages over film though, in that it's a lot less expensive to provide a digital than film version of the movie ... and unlike film it doesn't wear out and have to be replaced with a new copy.
