EIA/CEA-608 is the standard for legacy captions in Standard Definition, and is sometimes referred to as “Line 21.” The newer EIA/CEA-708 was created for digital broadcasts and adds new fonts, characters and symbols, text colors and styles, and more. Both EIA/CEA-608 and EIA/CEA-708 captions are required for ATSC digital broadcasts.
