AES52-2006, unique identifiers in AES3 transport stream, has been reaffirmed

 AES52-2006 (r2011) AES standard for digital audio engineering — Insertion of unique identifiers into the AES3 transport stream has been reaffirmed.

The AES3 transport stream continues to be used extensively in both discrete and network based audio systems alongside audio stored as files. Audio content is moving towards being handled by asset management systems and descriptive metadata associated with that content is also being stored within systems. In order to provide a mechanism for AES3 transport streams to have similar abilities to work with content management systems, some form of unique label is required which can provide the link with these systems. One of the unique labels currently standardised in the media industry is the SMPTE UMID while another commonly used in the Information Technology area is the IEC UUID.

This standard specifies the method for inserting unique identifiers into the user data area of an AES3 stream. This specifically covers the use of UUID as well as a basic or extended SMPTE UMID.
