Using a timecode stream is a solution. I think I am not yet at this level of specificity. What is this discontinuity thing ? You just want to specifiy a list of segments to play, period. >> (actually, possibly many audio and subtitles), should be playable in >> sync, whatever part is played in whatever sequence >> 2- a movie should be playable according to an edit list > > > ah, it's more subtle.

Why is it different from an edit list (using the QT terminology) ? Or a list of segments to play (using the MPEG-4 OD terminology). > I see 2 very much as a composition (temporal composition) requirement. I fully agree, but it is a requirement at the movie level, not at the TT level. The same is true for audio and video. A solution for the audio/video thing can be applied to the AVT triplet.
