These demonstrations, however, have not incorporated all of the components necessary for a broad based commercially viable Digital Cinema system. These demonstrations have created a great deal of discussion and confusion around defining the quality levels, system specifications, and the engineering standards necessary for implementing a comprehensive Digital Cinema system.

What is our purpose in Digital Cinema Technology?

Our main goal is to provide a secure and reliable digital movie distribution network based on DCI (Digital Cinema Initiatives) standard.

The details of DCI standard:

• Digital Cinema Distribution Master (DCDM): This section provides specifications for the image, audio, subtitle (Timed Text and subpictures) Digital Cinema Distribution Masters. The DCDM-Image defines a common set of image structures for Digital Cinema by specifying an image containers and colorimetry for a Digital Cinema Distribution Master (DCDM). The DCDM-Audio specifies the following characteristics: bit depth, sample rate, minimum channel count, channel mapping and reference levels. The DCDM-subtitles specifies the format of a Digital Cinema subtitle track file. A subtitle track file contains a set of instructions for placing rendered text or graphical overlays at precise locations on distinct groups of motion picture frames. A subtitle track file is an integral component of a Digital Cinema composition and may be present in both mastering and distribution file sets.

• Compression (Image): Specifies the DCI compliant JPEG 2000 codestream and JPEG 2000 decoder.

• Packaging: This section defines the requirements for packaging the DCDM (image, audio and subtitle) files using (where possible) existing Material eXchange Format(MXF) specifications and eXtensible Mark up Language (XML). The output of this process is the Digital Cinema Package (DCP). This section also defines the requirements for encrypting the essence (sound, picture and subtitles) of the DCP.

• Transport: Defines the movement from distribution centers to theater locations using physical media, virtual private networks or satellite communications.

• Theater Systems: Provides requirements for all equipment necessary for theatrical presentation in a typical theater environment. This encompasses digital projectors, media blocks, storage systems, sound systems, the DCP files ingest, theater automation, Screen Management   System (SMS) and Theater Management Systems (TMS).

• Projection: This section defines the projector and its controlled environment, along with the acceptable tolerances around critical image parameters for Mastering and general Exhibition applications. The goal is to provide a means for achieving consistent and repeatable color image quality. Two levels of tolerances are specified: a tighter tolerance for mastering rooms where critical color judgments are made, and a wider tolerance for satisfactory reproduction in general public exhibition.

• Security: The security chapter provides requirements and fundamental specifications for persistent content protection and controlled access in an open security architecture. These objectives are achieved with high security in a multi-user environment via the application of well respected security and encryption standards in primarily three areas: 1) content encryption, 2) security (key) management and 3) high integrity event logging and reporting.
