Definition

“The Timed-Text specification should covers all necessary aspects of timed text on the Web. Typical applications of timed text are the real time subtitling of foreign-language movies on the Web, captioning for people lacking audio devices or having hearing impairments, karaoke, scrolling news items or teleprompter applications.” (Timed-Text, retrieved 13:02, 27 September 2007 (MEST)).

TT is quite a complex format, but in some contexts (e.g. Flash captioning) understanding of a small subset will do.

Typical applications

According to [1]:

  • Subtitles of movies on the Web (foreign languages)
  • Captions for people lacking audio devices or having hearing disabilities
  • Karaoke
  • Scrolling news, credits rolls
  • TickerTape, marquee, "crawls"
  • Text overlay
  • TelePrompter

Related formats and software

Timed Text is supported to various degrees by various software, e.g.

There is also an interaction with other formats, e.g.
