Usage environment adaptation refers to customization of network and terminal resources based on usage and content.
Usage environment adaptation refers to the case where instead of adapting the content (i.e., its format, resolution, bit-rate, frame rate and coefficient dropping) to suit the usage environment properties, the usage environment is adapted (i.e., device resolution to accommodate video resolution, bandwidth) to suit to the content properties and hence provide better quality of service to users. Usage environment adaptation may consider the context and the content that can be described using multimedia metadata, such as the MPEG-7 and MPEG-21, respectively [1].
If the objective is to maximize content quality for an individual user by taking into account only user preferences and device constraints but disregarding shared resource constraints, then the adaptation becomes client-centric [2]. For example, client-centric...
