One of the big challenges in the convergence of networks and services to the IP technology is to maintain the Quality of service (QoS) for audio/video streams transmitted over wireless networks to heterogeneous mobiles users. In this environment, the multimedia services should face many shortcomings caused mainly by the wireless channel unreliability and its sharing among many users. These shortcomings are increased by the terminals heterogeneity (i.e. decoding capability, memory storage, display resolution, etc.) which should receive, decode and display the multimedia streams.In order to allow universal access to multimedia services anywhere, anytime and using any kind of terminal, the new generation of multimedia applications have to inte...
