AdaMS: An Adaptation Multimedia System for Heterogeneous Environments

This paper presents a new adaptation platform for composite multimedia documents in SMIL (synchronized multimedia integration language) format. Our adaptation system, named AdaMS, allows users of heterogeneous terminals to reach the same multimedia content. The platform assumes the management of user´s profiles (user preferences, device characteristics...) for the adaptation process, as well as the management of the new presentations versions, created according to the user profile. The adaptation process is a combination of on stock and on demand adaptation. The aim is to have a balance between the two methods to optimize the adaptation process. Unlike other existing platforms, our system gives the possibility to the user to begin the visualisation of the multimedia presentation before the end of the adaptation process, thus reducing user waiting time.
