Application of this standard includes 525-line and 625-line standard definition digital television interfaces (component or composite), and high definition digital television interfaces (750 and 1125 lines) and D-Cinema applications that provide 8-bit or 10-bit data ancillary data space. — Space available for ancillary data packets shall be defined in the document specifying the connecting interface. — Ancillary data packet payload definitions for a specific application shall be specified by a SMPTE standard, Recommended Practice, or Registered Disclosure Document, or by a document generated by another organization, company or an individual (Entity). When a payload format shall be registered with SMPTE, an application document describing the payload format shall be required and the registered ancillary data packet shall be identified by a registered data identification word.",
