Analog Caption Service
Caption1 (CC1)
CC1 is the primary caption service that synchronizes the captioning language with the
sound, used by most broadcasters. The captioning is displayed in the same language as
the program’s dialog.
Caption2 (CC2)
CC2 is the special non-synchronous caption service that does not need to be in sync with
the sound and may provide simplified captioning, which is usually delayed.
Caption3 (CC3)
CC3 serves as an alternate captioning service channel. The captioning is often a secondary
language translation such as French, Spanish, simplified English or displayed at a slower
rate.
Caption4 (CC4)
CC4 is another special non-synchronous caption service that does not need to be in sync
with the sound and may provide simplified captioning, usually delayed.
Text1-4
Text1-4 usually display information at the bottom position and is used for a data service,
generally not program related.
