SMPTE ST 2067-5:2013

This standard defines the IMF Essence Component, an OP1a MXF structure for interchange of audio, picture and data essence. 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. It also defines metadata expressions used to communicate allowable variations in the formulation of an IMF Essence Component.
