An Implementation of QoS Adaptive Multimedia Content Delivery

The rapid development of technology in Internet and wireless communication makes it possible for people to access multimedia contents and services using handheld devices. However, most multimedia contents and services in the Web are optimized for desktop computing environment. They contain rich media data, which are not suitable for handheld devices with limited capabilities and resources. Moreover, depending on user preference and application scenarios, not all the data are relevant or critical to the application. In this paper, we present a scheme for adapting multimedia contents on the wireless devices for QoS-aware delivery. Especially, we seek to adapt multimedia contents based on system and network resources available, client terminals, user preferences and other environment characteristics.
