Description

Abtract:

This standard defines one of two methods for mapping the serial audio metadata stream related to encoded audio bitstreams into the 10-bit vertical ancillary (VANC) data space of a standard definition or high definition digital component television signal in accordance with SMPTE ST 291-1. This VANC mapping conveys the audio metadata elements and carries information about the location of the embedded audio with which the metadata is associated. — An associated standard ST 2020-1 defines the DID and SDID values assigned to the VANC packets carrying this metadata, the location where packets are to be located, the basic structure of the metadata, and the asynchronous serial data transport which is used to convey the metadata from device to device (when not embedded in a video signal). — Note: An associated standard ST 2020-3 defines an alternate method of mapping the metadata into ancillary data packets.
