SMPTE ST 429-18:2019

Abtract:

This standard specifies the mapping of an ST 2098-2 Immersive Audio Bitstream into an MXF file for use within a Digital Cinema Package. The MXF Generic Container (GC), as described in SMPTE ST 379:2004, is used as a normative reference for this mapping, but ST 429-18 uses Class 14 ULs which prevents full compliance. The resultant file will be referred to as an Immersive Audio Track File. — This standard specifies the Key, the Length and the Value fields of the Immersive Audio Data Element. This standard also defines the Essence Container and the Essence Descriptors. — This standard defines the SMPTE ST 429-7 Composition Playlist asset type extension required for inclusion of an Immersive Audio track.
