Content Adaptation

The multiplication of execution contexts for multimedia documents requires the adaptation of document specifications to the particularities of the contexts. We proposed a semantic approach to multimedia document adaptation which was temporally defined with regards to the Allen algebra of relations. A new work [8] extends this framework to the spatial dimension of SMIL documents. It allows to find a qualitative spatial representation that computes a set of adaptation solutions close to the initial document respecting the adaptation constraints. The quality of an adaptation can be regarded on two respects : expressiveness of adaptation solutions and computation speed. In this context, we characterize the adaptation quality of existing spatial representations. We have shown that these representations do not provide optimal quality. Thus, we have proposed a new spatial representation which is sufficiently expressive and additionnaly allows to adapt SMIL documents faster.
