Abstract: MXF is a comprehensive file format being widely introduced into the broadcast world. The primary MXF standard is SMPTE 377M and this defines the file structure and metadata. In order to accommodate all currently used audio-visual stream formats and to provide for future developments, a generic essence container was developed (SMPTE 379M) that complied with SMPTE 377M and could be used to encapsulate many essence types. To date, many essence mappings have been written. Amongst these are a generic mapping of MPEG compressed data and a mapping of AES3 audio. This paper will identify those areas of MXF where constraints are applied to certain file components in order to encourage interoperability between various kinds of storage devices using both linear and non-linear storage media. The paper will consider constraints at the following two layers: Constraints on the use of the MXF file format structure Constraints on the essence data mappings. The file constraints include the operational pattern, the use of partitions, the placement of index table segments in the file partitions, the use of index table segments and use of the KLV Fill item.
