Multimedia adaptation for dynamic environments

چکیده
This paper presents a new approach for adapting a multimedia presentation into heterogeneous and dynamically changing environments. A novel media adaptation taxonomy is proposed that includes synchronized media optimization and scaling. The taxonomy incorporates multi-dimensional interaction between media, service requirements and presentation. Network properties, terminal types and integration capabilities differ in presentation requirement profile(s). Understanding the relationship between media information and these service characteristics benefits the presentation process. Using our taxonomy, a concrete service presentation are shown, with adaptation properties in different situations and for different types of terminals. The advantages of the content-based adaptation taxonomy are demonstrated with an example of an entire (end-to-end) multimedia service system in a dynamic environment.

متن کاملCOCA: A Contract-Based Infrastructure for Collaborative Quality-of-Service Adaptation
Achieving acceptable quality of service in highly dynamic computing environments requires not only adaptation and reconfiguration of individual components of the system, but also collaboration among these components. To address the integration and collaboration of adaptive computing components, we propose COCA, a contract-based collaborative adaptation infrastructure. COCA uses contract specifi...
متن کاملDynamic Configuration of Multimedia Applications
Streaming multimedia applications, such as video on demand or conferencing are increasingly deployed in heterogeneous and mobile environments including Workstations, PDAs, mobile phones, etc. These applications are very resource demanding and in general, they need to be dynamically adapted when executed on low capability terminals. The proxybased content adaptation approach is well suited to tr...
