This standard specifies the common features of the format of sound and picture Tracks Files for distribution of D-Cinema content using the MXF file format. It defines data structures for interchange at the signal interfaces of networks or storage media, but does not define internal storage formats for compliant devices or mappings for particular essence encodings. This document is an Application Specification for D-Cinema applications. It is based on the SMPTE 390M OP-ATOM standard, but is further constrained to address the needs of distribution of D-Cinema content to exhibition sites.
