Content Processing

Content Processing Stages DSM DCDM DCP DCDM* Image & Sound • Digital Source Master (DSM) arrives from post production. • Digital Distribution Master (DCDM) is created: – Image: JPEG2000 compressed & Media Exchange Format mapped. – Sound: Uncompressed; Broadcast Wave (.wav) formatted. – Captioning & Subtitling are supported in multiple formats. – Encryption is optionally applied to any of the above. • Digital Cinema Package (DCP) is what is distributed, as a compilation of DCDMs. • DCDM(s) are reconstituted at exhibition at time of playout. – Typical 3 hour show requires 300-400 GBytes storage (compressed) – Max compressed bit rate: 250 Mbit/sec * DCDM is recovered from slightly lossy compression 12
