TL;DRAbstract

The objective of Universal Multimedia Access (UMA) is to permit any user equipped with whatever device the access to multimedia information. To handle the problems of UMA, two different approaches are commonly used: store variations of the same content and send the most appropriate one, and store the original content and adapt it on-the-fly.

The tools allowing to reach this goal are: an Annotation Tool which describes media using MPEG-7, and a Client-Server Application that takes all the steps for the browsing and retrieval of media.

Particular insight is given into the handling of user preferences and devic
