It specifies the structure of packets carrying CEA-708, as well as CEA-608 closed captioning data, time code data, and ATSC A/65 closed caption descriptor information, which may be carried in vertical ancillary data space, via serial data communications interfaces, or via other means. — The related data services include data broadcast services intended for the public as well as broadcaster internal control and communications.",
