This Standard defines the basic structure and timing requirements of an asynchronous serial audio metadata stream with respect to an associated video signal. These requirements apply to the serial metadata streams either present on asynchronous serial data communications links between devices or present in the vertical ancillary (VANC) data packets transported by the video signal. The Standard also defines the Data ID (DID) and Secondary Data ID (SDID) values used to identify the VANC packets themselves and to associate the metadata in VANC packets with specific audio programs.
This Standard defines levels of operation for two methods of mapping the metadata into ancillary data packets.
