Perception needs comparison but comparing different parts of a temporal document is not an easy task though. We have build up a set of methods to split up temporal documents (such as digital videos or musical recordings) into discrete objects. Ergonomic interfaces are then developped to exploit these results. In these interfaces, browsing fonctionnalities and extracts selection are simple and fast. Those kind of representations help contents perception as well as documents analysis. In order to do so, we propose an interface that enables to program the rendering of the discrete objects. This "un-sequencing" of the document is brought out various comparing functionalities that can be used with extracts of documents of the same or different media.
