W3C has published a First Public Working Draft for Timed Text (TT) Authoring Format 1.0 — Distribution Format Exchange Profile (DFXP). The draft has been produced by members of the Timed Text (TT) Working Group as part of the W3C Synchronized Multimedia Activity.
The W3C Timed Text Working Group was chartered in January 2003 to "develop an XML-based format used for the representation of streamed text synchronized with other timed media, like audio and video. A typical application is real time captioning of movies on the Web (e.g., integrated in
* No standard method for displaying text synchronized with other media.
* Need for a standard Timed Text format synchronized with some other timed media.
Timed Text applications
* 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
SMIL Interoperability
* Good interoperability on synchronization level
* Not so good interoperability for media

Abstract
This document specifies the distribution format exchange profile (DFXP) of the timed text authoring format (TT AF) in terms of a vocabulary and semantics thereof.
The timed text authoring format is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.
The Distribution Format Exchange Profile is intended to be used for the purpose of transcoding or exchanging timed text
