This Standard defines a method of coding that allows Active Format Description (AFD) and Bar Data information to be carried in the 10-bit vertical ancillary (VANC) data space of a standard definition or high definition component television signal. The standard defines how the AFD and Bar Data information is placed into an AFD/Bar Data ancillary data packet for carriage in accordance with SMPTE 291M.

An associated standard, SMPTE ST 2016-1, defines the format for AFD and Bar Data and identifies the video image and interface standards with which it may be associated. Annex C shows the relationship among the standards.
