<blockquote type=cite class=cite cite="">I was wondering about how
broadcast (podcast) streams should be tagged. ID3 does an excellent job
of providing song recording information, and the basic structure of the
tag or something very compatible with it would seem to be useful to tag
podcast streams. <br><br>
Consider for example the NPR Radio show "This American Life".
It's got multiple distinct audio segments each show, as well as
introductory, transitional, and conclusion audio segments. It would be
nice if within the mp3 tag we could mark the offsets into the mp3 where
these parts of the broadcast exist, so that a program that reads the tag
could provide a link into the mp3 to the point where the segment begins
or ends. <br><br>
As another example consider a sports event. The final broadcast might
provide links to an outline of a game, in American football, maybe the
beginning and ending of downs, particular penalty or injury breaks,
points scored - key plays. etc. <br><br>
Further it would be nice for the end user of a broadcast to be able to
highlight the segments he/she particular likes by adding labels and
markers within the header of the stream's tag, to provide a more
customized index of the broadcast. </blockquote><br>

The new ID3v2 Chapter Addendum can do all of these things. It's available
here:<br><br>
<a href="http://www.id3.org/id3v2-chapters-1.0" eudora="autourl">
http://www.id3.org/id3v2-chapters-1.0<br><br>
</a>Unfortunately. it's not widely supported by authoring systems or
media players as yet.<br><br>

There is a Sourceforge project which provides an authoring tool for ID3v2
Chapters here:<br><br>
