An Adaptation Technique for Multimedia Applications Based On the User Context to Manage the Service Quality

Abstract-Currently, the adaptation of multimedia applications is necessary, because documents can be accessed at anytime and anywhere with a wide variety of devices, such as PDAs, laptops and tablets. Unfortunately, in most applications dedicated to this type of problem, are essentially based on the heterogeneity of the data (image, sound, text, video and encoding format for each type), related to a user context, the context of terminal and network receiver and transmitter. In this paper. We propose an architecture on-the-fly adaptation of multimedia documents. More precisely, we propose a procedure that selects the relevant adaptation policies to build a document adapted to ensure quality of service and to consider the limits users (physical handicap, preferences of users)

On-the-fly Multimedia Document Adaptation Architecture

International audienceCurrently, multimedia contents can be accessed at anytime and anywhere with a wide variety of devices, such as laptops, smartphones and tablets. In this paper, we present a service-based multimedia adaptation architecture where adaptation services can be available locally and remotely on multiple platforms. When conflicts are detected between some multimedia document properties and profile constraints, we propose a procedure that selects relevant adaptation services in order to compute an adapted document. This procedure may be executed locally or remotely, moreover for unsovled conflicts this one indicates which services may have to be installed
