Currently, much research aims at coping with the short- comings in multimedia consumption that may exist in a user's current context, e.g., due to the absence of appro- priate devices at many locations, a lack of capabilities of mobile devices, restricted access to content, or non- personalized user interfaces. Recently, solutions to specific problems have been emerging, e.g., wireless access to mul- timedia repositories over standardized interfaces; however, due to usability restrictions the user has to spend much ef- fort to or is even incapable of fulfilling his/her demands. The vision of user-centric multimedia places the user in the center of multimedia services to support his/her multimedia consumption intelligently, dealing with the aforementioned issues while minimizing required work. Essential features of such a vision are comprehensive context awareness, per- sonalized user interfaces, and multimedia content adapta- tion. These aspects are addressed in this paper as major challenges toward a user-centric multimedia framework.
