You also might want to have a look at the following demo in case you are
interested in a possible link between MPEG-21 Digital Item Declarations,
SMIL and HTML + TIME: http://multimedialab.elis.ugent.be/demo.asp (look for
"Temporal synchronization of media within MPEG-21 Digital Item
Declarations"). Note that the concepts behind this demo most probably 
diverge from your thesis topic.
