Multimedia adaptation for dynamic environments

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 is 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
