Timed Divs HTML
This page specifies a subclass of HTML documents that is a time-aligned text format for audio-visual content. We call the format "timed divs within HTML" or TDHT. It is intended to be used only in a World Wide Web context i.e. everywhere that Web browser functionality is available. Use cases for the format are subtitles, captions, annotations and other time aligned text as listed at http://wiki.xiph.org/index.php/OggText#Categories_of_Text_Codecs .
Files in this format are to be of text/x-tdht mime type.
Files in this format should have a file extension of .tdht .
The TDHT format
TDHT files are time-aligned text. This means there is a time association with blocks of text and there is time-based seeking functionality on those blocks of text.
Here is an example tdht file for subtitles:
<html> <head> <title>Desperate Housewives - Season 5, Episode 6</title> </head> <body> <div start="00:00:00,070" end="00:00:02,270"> <p>Previously on...</p> </div> <div start="00:00:02,280" end="00:00:04,270"> <p>We had an agreement to keep things casual.</p> </div> <div start="00:00:04,280" end="00:00:06,660"> <p>Susan made her feelings clear.</p> </div> <div start="00:00:06,800" end="00:00:10,100"> <p>So if I was with another woman, that wouldn't bother you? No, it wouldn't.</p> </div> </body> </html>
