	Movies - Digital Cinema Initiatives

Digital Cinema Initiatives or DCI is a consortium of studios and vendors formed to establish a standard architecture for digital cinema systems. The organization was formed in March 2002 as a joint venture of the following studios:

Disney
Fox
MGM
Paramount
Sony Pictures Entertainment
Universal
Warner Bros.

DCI's primary purpose is to develop a specificiation that describes a common, open standard for digital cinema that can be adopted by all distributors, studios and vendors.

Because of the relationship of DCI to many of Hollywood's key studios, conformance to DCI's specifications is considered a requirement by any software developer or equipment manufacturer targeting the digital cinema market.

Specification

On July 202005, DCI released its first version of the final overall system requirements and specifications for digital cinema and made it .

Based on many SMPTE standards, such as JPEG 2000-compressed image and "Broadcast wave" PCM/WAV sound, it explains the route to create an entire Digital Cinema Package (DCP) from a raw collection of files known as the Digital Cinema Distribution Master (DCDM), as well as the specifics of its content protection, encryption, and forensic marking.

The specification also establishes standards for the decoder requirements and the presentation environment itself, such as ambient light levels, pixel aspect and shape, image luminance, white point chromaticity, and those tolerances in which it should be kept.

Universal Pictures used their film Serenity
as the first DCP to be delivered shown to an audience at a remote theater, although it was not distributed this way to the public.
