This Standard defines Active Format Description (AFD) and Bar Data for origination and conveyance through the production and distribution processes for standard definition or high definition television signals. AFD and Bar Data are intended to be ultimately broadcast with the video signals that they describe, therefore references to emission and DTV receivers are included to ensure compatibility between the origination of the AFD and Bar Data and its ultimate use.
Associated standards define how this information is placed into ancillary data packets and is KLV coded as SMPTE metadata. Annex C shows the relationship among the standards.
