SMPTE 408M – Television – Material Exchange Format (MXF) – Operational Patterns 1c, 2c and 3c

This standard defines operational patterns 1c, 2c and 3c, as defined in SMPTE 377M section 7, for theexchange of MXF files that represent the following levels of file complexity:

–OP1c: A choice of 2 or more alternate material packages that play out selected tracks of either a singlefile package or two or more synchronized file packages,

–OP2c: A choice of 2 or more alternate material packages that play out selected tracks of either asequence of single file packages, or a sequence of two or more synchronized file packages,

–OP3c: A choice of 2 or more alternate material packages that play out selected portions of tracks (editlist) from one or more file packages each of which may be referenced and synchronized at any givenposition along the timeline.

In each case, a top-level file package is linked to an essence container where each essence container maycomprise either a single essence element or an interleave of multiple essence elements. Furthermore, in eachcase, one or more of the essence containers may be internal or external to the file.

This standard defines the operating restrictions, structural metadata objects and individual attributes that shallbe applied to the MXF file format specification to achieve interoperability when exchanging an MXF file withthese operational patterns.

These operational patterns require the use of body partitions for internal essence containers. Subdivision ofeach essence container by using body partitions is optional.
