    2. D-Cinema System Workflow

    3. Mastering

    Digital Cinema Distribution Master (DCDM) Image: TIFF Audio: WAV Subtitles: PNG Color: 2D = 12 bit, 4:4:4, XYZ 3D = 10 bit, 4:2:2, XYZ

    4. Compression

    In 2004 DCI selected JPEG2000 as the compression technology of choice for Digital Cinema. Why use compression in Digital Cinema? 2048 x 1080 container = 2,211,840 pixels Each pixel is represented by three 12-bit values 9.5 megabytes per frame 2 hour feature = 172,800 frames (24 fps) Uncompressed = 1.5 terabytes JPEG2000 Compression = 100 - 300 gigabytes

    5. Packaging

    Digital Cinema Package (DCP) Distribution package including individual clips and CPLs Composition Play List (CPL) XML instructional document for the player What to play and when to play it
